    Hypotheses and tracking results about the longest migration: the case of the arctic tern2019Inngår i: Ecology and Evolution, E-ISSN 2045-7758Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone. Salomonsen (1967, Biologiske Meddelelser, Copenhagen Danske Videnskabernes Selskab24, 1) put forward a hypothetical comprehensive interpretation of this global migration pattern, suggesting food distribution, wind patterns, sea ice distribution, and molt habits as key ecological and evolutionary determinants. We used light‐level geolocators to record 12 annual journeys by eight individuals of arctic terns breeding in the Baltic Sea. Migration cycles were evaluated in light of Salomonsen's hypotheses and compared with results from geolocator studies of arctic tern populations from Greenland, Netherlands, and Alaska. The Baltic terns completed a 50,000 km annual migration circuit, exploiting ocean regions of high productivity in the North Atlantic, Benguela Current, and the Indian Ocean between southern Africa and Australia (sometimes including the Tasman Sea). They arrived about 1 November in the Antarctic zone at far easterly longitudes (in one case even at the Ross Sea) subsequently moving westward across 120–220 degrees of longitude toward the Weddell Sea region. They departed from here in mid‐March on a fast spring migration up the Atlantic Ocean. The geolocator data revealed unexpected segregation in time and space between tern populations in the same flyway. Terns from the Baltic and Netherlands traveled earlier and to significantly more easterly longitudes in the Indian Ocean and Antarctic zone than terns from Greenland. We suggest an adaptive explanation for this pattern. The global migration system of the arctic tern offers an extraordinary possibility to understand adaptive values and constraints in complex pelagic life cycles, as determined by environmental conditions (marine productivity, wind patterns, low‐pressure trajectories, pack‐ice distribution), inherent factors (flight performance, molt, flocking), and effects of predation/piracy and competition.

    Increasing melanism along a latitudinal gradient in a widespread amphibian: local adaptation, ontogenic or environmental plasticity?2010Inngår i: BMC Evolutionary Biology, E-ISSN 1471-2148, Vol. 10, s. 317-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BackgroundThe thermal benefits of melanism in ectothermic animals are widely recognized, but relatively little is known about population differentiation in the degree of melanism along thermal gradients, and the relative contributions of genetic vs. environmental components into the level of melanism expressed. We investigated variation in the degree of melanism in the common frog (Rana temporaria; an active heliotherm thermoregulator) by comparing the degree of melanism (i) among twelve populations spanning over 1500 km long latitudinal gradient across the Scandinavian Peninsula and (ii) between two populations from latitudinal extremes subjected to larval temperature treatments in a common garden experiment.

    ResultsWe found that the degree of melanism increased steeply in the wild as a function of latitude. Comparison of the degree of population differentiation in melanism (PST) and neutral marker loci (FST) revealed that the PST > FST, indicating that the differences cannot be explained by random genetic drift alone. However, the latitudinal trend observed in the wild was not present in the common garden data, suggesting that the cline in nature is not attributable to direct genetic differences.

    ConclusionsAs straightforward local adaptation can be ruled out, the observed trend is likely to result from environment-driven phenotypic plasticity or ontogenetic plasticity coupled with population differences in age structure. In general, our results provide an example how phenotypic plasticity or even plain ontogeny can drive latitudinal clines and result in patterns perfectly matching the genetic differences expected under adaptive hypotheses.

    Association between autoantibodies to the Arginine variant of the Zinc transporter 8 (ZnT8) and stimulated C-peptide levels in Danish children and adolescents with newly diagnosed type 1 diabetes2012Inngår i: Pediatric Diabetes, ISSN 1399-543X, E-ISSN 1399-5448, Vol. 13, nr 6, s. 454-462Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    The zinc transporter 8 (ZnT8) was recently identified as a common autoantigen in type 1 diabetes (T1D) and inclusion of ZnT8 autoantibodies (ZnT8Ab) was found to increase the diagnostic specificity of T1D.

    Objectives

    The main aims were to determine whether ZnT8Ab vary during follow-up 1 year after diagnosis, and to relate the reactivity of three types of ZnT8Ab to the residual stimulated C-peptide levels during the first year after diagnosis. Subjects A total of 129 newly diagnosed T1D patients <15 years was followed prospectively 1, 3, 6, and 12 months after diagnosis.

    Methods

    Hemoglobin A1c, meal-stimulated C-peptide, ZnT8Ab, and other pancreatic autoantibodies were measured at each visit. Patients were genotyped for the rs13266634 variant at the SLC30A8 gene and HLA-DQ alleles. Results The levels of all ZnT8Ab [ZnT8Arg (arginine), ZnT8Trp (tryptophan), ZnT8Gln (glutamine)] tended to decrease during disease progression. A twofold higher level of ZnT8Arg and ZnT8Gln was associated with 4.6%/5.2% (p = 0.02), 5.3%/8.2% (p = 0.02) and 8.9%/9.7% (p = 0.004) higher concentrations of stimulated C-peptide 3, 6, and 12 months after diagnosis. The TT genotype carriers of the SLC30A8 gene had 45.8% (p = 0.01) and 60.1% (p = 0.002) lower stimulated C-peptide 6 and 12 months after diagnosis compared to the CC and the CT genotype carriers in a recessive model.

    Conclusions

    The levels of the Arg variant of the ZnT8 autoantibodies are associated with higher levels of stimulated C-peptide after diagnosis of T1D and during follow-up. Carriers of the TT genotype of the SLC30A8 gene predict lower stimulated C-peptide levels 12 months after diagnosis.

    Stochastic modeling and optimal time-frequency estimation of task-related HRV2019Inngår i: Applied Sciences, E-ISSN 2076-3417, Vol. 9, nr 23, s. 1-16, artikkel-id 5154Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we propose a novel framework for the analysis of task-related heart rate variability (HRV). Respiration and HRV are measured from 92 test participants while performing a chirp-breathing task consisting of breathing at a slowly increasing frequency under metronome guidance. A non-stationary stochastic model, belonging to the class of Locally Stationary Chirp Processes, is used to model the task-related HRV data, and its parameters are estimated with a novel inference method. The corresponding optimal mean-square error (MSE) time-frequency spectrum is derived and evaluated both with the individually estimated model parameters and the common process parameters. The results from the optimal spectrum are compared to the standard spectrogram with different window lengths and the Wigner-Ville spectrum, showing that the MSE optimal spectral estimator may be preferable to the other spectral estimates because of its optimal bias and variance properties. The estimated model parameters are considered as response variables in a regression analysis involving several physiological factors describing the test participants’ state of health, finding a correlation with gender, age, stress, and fitness. The proposed novel approach consisting of measuring HRV during a chirp-breathing task, a corresponding time-varying stochastic model, inference method, and optimal spectral estimator gives a complete framework for the study of task-related HRV in relation to factors describing both mental and physical health and may highlight otherwise overlooked correlations. This approach may be applied in general for the analysis of non-stationary data and especially in the case of task-related HRV, and it may be useful to search for physiological factors that determine individual differences.

    Solving problems in social-ecological systems: definition, practice and barriers of transdisciplinary research2013Inngår i: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 42, nr 2, s. 254-265Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Translating policies about sustainable development as a social process and sustainability outcomes into the real world of social-ecological systems involves several challenges. Hence, research policies advocate improved innovative problem-solving capacity. One approach is transdisciplinary research that integrates research disciplines, as well as researchers and practitioners. Drawing upon 14 experiences of problem-solving, we used group modeling to map perceived barriers and bridges for researchers' and practitioners' joint knowledge production and learning towards transdisciplinary research. The analysis indicated that the transdisciplinary research process is influenced by (1) the amount of traditional disciplinary formal and informal control, (2) adaptation of project applications to fill the transdisciplinary research agenda, (3) stakeholder participation, and (4) functional team building/development based on self-reflection and experienced leadership. Focusing on implementation of green infrastructure policy as a common denominator for the delivery of ecosystem services and human well-being, we discuss how to diagnose social-ecological systems, and use knowledge production and collaborative learning as treatments.

    Integrating sustainability in higher education: a Swedish case2020Inngår i: International Journal of Sustainability in Higher Education, ISSN 1467-6370, Vol. 21, nr 6, s. 1131-1150Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose – This paper aims to unveil how sustainability is integrated into the courses/programmes ofhigher education institutions. The research question addressed is: how do academics representing differentdisciplines cooperate and engage in the work of integrating sustainability into their teaching programmes.Design/methodology/approach – This paper draws upon the notions of practise variation andinstitutional work from institutional theory and empirically focusses on the case of Kristianstad University(Sweden). This case is based on an autoethnographic approach and illustrates the experiences shared by sixcolleagues, representing different disciplines, engaged in implementing sustainability in their courses/programmes.Findings – The findings highlight how academics representing different disciplines, with specific traditionsand characteristics, face the sustainability challenge. Despite being bound by similar sustainable developmentgoals, differences across disciplines need to be acknowledged and used as an asset if trans-disciplinarity is theultimate goal.Research limitations/implications – Although the intrinsic motivation of individuals to work withsustainability might be a strong driver, the implementation of sustainability within courses/programmes andacross disciplines requires joint efforts and collective institutional work.Practical implications – By highlighting how academics engage in the work of integratingsustainability, this study emphasizes that managers of higher education institutions need to account for thetime and additional resources needed to ensure that academics effectively cope with sustainability. Intrinsicmotivation may not last if organizational structures and leadership are not supportive on a practical level andin the long run.

    Geographic location, not forest type, affects the diversity of spider communities sampled with malaise traps in Sweden2016Inngår i: Annales Zoologici Fennici, ISSN 0003-455X, E-ISSN 1797-2450, Vol. 53, nr 3-4, s. 215-227Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The latitudinal diversity gradient predicts higher species richness at lower latitudes. Here, we utilize the data from a long-term monitoring with malaise traps to analyse if spider communities in Sweden are affected by geographic gradients and if these effects hold independent of forest type. The species richness and the effective number of species in spider communities were not significantly related to the latitudinal gradient. The effective number of species and the taxonomic distinctness of spider communities were related to longitude, with a higher number, but fewer related species in western parts of Sweden. The species and family composition were significantly related to latitude independent of forest type, with a dominance of Linyphiidae individuals and species in the north. Our study demonstrates the suitability of malaise trap sampling to contribute to a better understanding of local spider communities, as several rare and locally new species were recorded in this study.

    Early springs and breeding performance in two sympatric duck species with different migration strategies2014Inngår i: Ibis, ISSN 0019-1019, E-ISSN 1474-919X, Vol. 156, nr 2, s. 288-298Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The capacity of migratory species to adapt to climate change may depend on their migratory and reproductive strategies. For example, reproductive output is likely to be influenced by how well migration and nesting are timed to temporal patterns of food abundance, or by temperature variations during the brood rearing phase. Based on two decades (1988–2009) of waterfowl counts from a boreal catchment in southern Finland we assessed how variation in ice break-up date affected nesting phenology and breeding success in two sympatric duck species, Mallard Anas platyrhynchos and Eurasian Teal Anas crecca. In Fennoscandia these species have similar breeding habitat requirements but differ in migration distance; Teal migrate roughly seven times as far as do Mallard. Annual ice break-up date was used as a proxy of spring ‘earliness’ to test the potential effect of climate change on hatching timing and breeding performance. Both species were capable of adapting their nesting phenology, and bred earlier in years when spring was early. However, the interval from ice break-up to hatching tended to be longer in early springs in both species, so that broods hatched relatively later than in late springs. Ice break-up date did not appear to influence annual number of broods per pair or annual mean brood size in either species. Our study therefore does not suggest that breeding performance in Teal and Mallard is negatively affected by advancement of ice break-up at the population level. However, both species showed a within-season decline in brood size with increasing interval between ice break-up and hatching. Our study therefore highlights a disparity between individuals in their capacity to adjust to ice break-up date, late breeders having a lower breeding success than early breeders. We speculate that breeding success of both species may therefore decline should a consistent trend towards earlier springs occur.

    Time use and foraging behaviour in pre-breeding dabbling ducks Anas spp. in sub-arctic Norway2015Inngår i: Journal of Ornithology, ISSN 2193-7192, E-ISSN 2193-7206, Vol. 156, nr 2, s. 499-513Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We studied time budgets and foraging methods in pre-breeding Mallard Anas platyrhynchos, (Eurasian) Teal Anas crecca, Wigeon Anas penelope, Pintail Anas acuta, Shoveler Anas clypeata and Gadwall Anas strepera in subarctic Norway in May. Among all six species studied, foraging accounted for the most common use of time, ranging from 19 % in male Pintail to 40–60 % in female Mallard, Teal, Pintail and Gadwall. Comfort behaviours amounted to 20–34 % of the time budget, and interaction and disturbance were marginal. Vigilance time ranged from 8 % in female Mallard to 20 % in male Pintail. Movement amounted to some 20 % of the time in most species and sexes. In Wigeon, sexes did not differ in time use, whereas in Mallard, Pintail and, in particular, Teal, females foraged more and engaged less in vigilance and interactions than did males. In addition, Teal and Mallard males engaged in the riskier foraging methods less than females, but more in those permitting vigilance. Although overlap in feeding methods was large among these species, Mallard and Teal were generalists, feeding at all depths, Wigeon foraged mainly in shallow water and Pintail foraged essentially in deep water. Our results support the income/capital breeder hypothesis with respect to males only; compared to lighter species, heavier species allocated less time to foraging but more to vigilance. We found no support for the hypothesis that long-distance migrants forage more to compensate for energy loss due to migratory flight. Foraging time in females was related to breeding phenology; early nesters spent more time feeding than later nesters.

    Rapid detection of antibiotic resistance in positive blood cultures by MALDI-TOF MS and an automated and optimized MBT-ASTRA protocol for Escherichia coli and Klebsiella pneumoniae2019Inngår i: Infectious Diseases, ISSN 2374-4235, E-ISSN 2374-4243Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: For fast and effective antibiotic therapy of serious infections like sepsis, it is crucial with rapid information about antibiotic susceptibility, especially in a time when the number of infections caused by multi resistant bacteria has escalated in the world.Methods: Here, we have used a semi-quantitative MALDI-TOF-MS based method for antibiotic resistance detection, MBT-ASTRA™, which is based on the comparison of growth rate of the bacteria cultivated with and without antibiotics. We demonstrate a new protocol where several parameters have been optimized and automated leading to reduced hands-on time and improved capacity to simultaneously analyse multiple clinical samples and antibiotics.Results: Ninety minutes of incubation at 37 °C with agitation was sufficient to differentiate the susceptible and resistant strains of E. coli and K. pneumoniae, for the antibiotics cefotaxime, meropenem and ciprofloxacin. In total, 841 positive blood culture analyses of 14 reference strains were performed. The overall sensitivity was 99%, specificity 99% and the accuracy 97%. The assay gave no errors for cefotaxime (n = 263) or meropenem (n = 289) for sensitive and resistant strains, whilst ciprofloxacin (n = 289) gave six (0.7%) major errors (false resistance) and four (0.5%) very major errors (false susceptibility). The intermediate strains showed a larger variety compared to the E-test MIC values.Conclusions: The hands-on time and the analysis time to detect antibiotic resistance of clinical blood samples can be substantially reduced and the sample capacity can be increased by using automation and this improved protocol.

    Optimization of several parameters in order to reduce time in antibiotic susceptibility testing in a clinical laboratory2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Background - When sepsis or bacteraemia is suspected, patient blood samples are cultivated in blood culture bottles and then further incubated for identification of the organism and antimicrobial susceptibility testing. These methods are slow, identifying causative pathogens in a couple of hours, and antibiotic susceptibility results within 18-36 hours.

    Here we present optimization of several parameters in order to evaluate if the MBT ASTRA™ method can be a rapid tool, used for routine antibiotics susceptibility testing, in a clinical laboratory.

    Methods – MALDI-TOF MS measurements were performed with a Microflex LT/SH bench-top mass spectrometer (Bruker) with standard settings. The resulting spectra were uploaded in the MBT-ASTRA™ software, which normalizes the peaks and determines the AUC and RG values for each setup.

    Results - The bacterial preparation steps generated a new protocol, which reduced time with 30-60 minutes.

    The antibiotics susceptibility test was optimized for 90 minutes incubation time. 200 µl McFarland 0.5 bacterial suspension in broth were incubated in broth at 37°C, with and without 32 µg/ml Cefotaxime, 16 µg/ml Meropenem and 4 µg/ml Ciprofloxacin.

    The suspensions were transferred to 0.45 µm pore size filter membraned 96 well plate. They were centrifuged; washed; fixated and eluted; put on a MALDI-target, and covered by matrix solution. All could be automated with robot, which reduced time with 60 minutes.

    Conclusion – Rapid susceptibility testing becomes more requested with the increase of resistance bacteria causing infections. Our study can be a valuable tool for clinical laboratories striving for reduction in time handling of antibiotic susceptibility testing.

    In vitro cytotoxicity evaluation of HDAC inhibitor Apicidin in pancreatic carcinoma cells subsequent time and dose dependent treatment2015Inngår i: Toxicology Letters, ISSN 0378-4274, E-ISSN 1879-3169, Vol. 236, nr 1, s. 8-15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Apicidin is a potent histone deacetylase inhibitor (HDACI) that selectively binds to histone deacetylases (HDACs) class I and interferes with the deacetylation process, which results in modification of acetylation level of cellular proteins. The aim of the study was to investigate the potential time and dose dependent cytotoxicity of the test compound, Apicidin, in pancreatic cancer cells Capan-1 and Panc-1 as well as estimate maximal tolerable dose (MTD) of the test agent and determine EC50 using four complementary colorimetric cytotoxicity or viability assays. The cells were treated with increasing concentrations of Apicidin (0-5000nM) for 2, 4 and 6h (short term exposure) or 24, 48 and 72h (long term exposure) before conducting cytotoxic analyses with lactate dehydrogenase assay or viability analyses with sulforhodamine B (SRB), methyl tetrazolium (MTT) and crystal violet (CV) assays. In order to investigate whether Apicidin irreversibly affects the cells already during the short term exposure, the medium containing Apicidin was removed and replaced with fresh culturing medium after 6h of treatment. The cells were then incubated for additional 24, 48 or 72h before carrying out the analysis. The results obtained from cytotoxicity and viability assays indicated, that Apicidin was well tolerated by both cell lines at concentrations below 100nM at any given time point and at all applied concentrations during the short term (6h or less) treatment. Continuous prolonged term exposures (48h or greater) of the cells to Apicidin with concentration exceeding 100nM resulted in significantly increasing cytotoxicity and sustained significant loss of cell viability. Moreover, long term exposure of pancreatic cancer cells Capan-1 and Panc-1 to Apicidin concentrations exceeding 100nM showed an initial anti-proliferative effect before cytotoxicity onset. In summary, MTD was exposure time dependent and estimated to 100nM for long term treatment and to at least 5000nM for treatment not greater than 6h. EC50 concentration of Apicidin was established after long term treatment, however with some variation when comparing the different assays and cell lines. Results from this study may encourage reinvestigating the capacity of potent HDACI Apicidin as an attractive agent for interfering with the deacetylation process catalyzed by HDACs for potential pancreatic cancer intervention.

    Childhood collecting in nature: quality experience in important places2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    There is growing concern for both the decline of direct experience people have with nature, and the quality of that experience. This diminished experience has negative consequences for public awareness and concern for biodiversity and ecosystem health (Miller, 2005). At the same time, a diminished experience of nature appears to have a substantial negative impact on child development (Kahn & Friedman, 1995; Kahn, 2002; Matteo, Barthel, & Lars, 2014; Pyle, 1993; Thomashow, 2002). These concerns are heightened in the urban context where increased urbanization shows a relationship with a reduction in biodiversity and ecosystem health (MA, 2005; Sala et al., 2000). Additional concern comes from studies showing decreasing ecological knowledge among growing urban populations (McDaniel & Alley, 2005; McKinney, 2002). In an attempt to address these concerns and contribute toward a better understanding of the importance of childhood experience of nature, this study investigates one specific example, collecting in nature. Studies show that childhood collecting in nature (the gathering of rocks, shells, feathers, etc. as part of play and free exploration) is a widespread phenomenon (Lekies & Beery, 2013), and yet, very little is understood about this behavior. This study explored the details of childhood collecting in nature with an emphasis on the places of this experience. Participants consisted of a random sample of undergraduate students at a Swedish university (N = 380) participating in a survey focused upon early life outdoor experiences. Responses included multiple choice and Likert scale items, along with data from open-ended questions. In addition, participants were invited to discuss their experience of childhood collecting in greater detail via a semi-structured interview. Fourteen interviews were conducted as follow-up to the survey. Data review considered descriptive statistics, correlations, and regression analysis triangulated with the qualitative data from the open-ended responses and interviews. Results highlight the importance of specific places in the childhood experience of nature, the importance of nearby nature, and further, provide preliminary support for a model for environmental concern (Wolf-Watz, 2015). Ultimately, the study illuminates the idea of childhood development as a cultural ecosystem service and provides implications for nature-based solutions, such as green infrastructure, to support childhood nature experience.

    Nordic In Nature: Friluftsliv and Environmental Connectedness2013Inngår i: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871, Vol. 19, nr 1, s. 94-117Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study explored the question of whether a relationship exists between the Nordic cultural idea of friluftsliv and the psychological construct of environmental connectedness (EC). This quantitative study employed a correlational design with existing data from the Swedish Outdoor Recreation in Change national survey. Results indicate that there is a significant and meaningful relationship between friluftsliv, operationally defined as nature-based outdoor recreation participation, and EC even when controlling for other predictor variables. In addition, research findings indicate that age group moderates this relationship with one group exception. It was also found that activity participation by respondents shows a correlation with both EC and age group. Implications of this study support a cultural understanding of nature-based outdoor recreation and an awareness of the important role of access to nature as an essential component of nature-based outdoor recreation. Age group differences supported a variety of implications and recommendations for future research. A consideration of how the results may have implications for environmental education and sustainability efforts were explored.

    What we can learn from environmental and outdoor education during COVID-19: a lesson in participatory risk management2020Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 21, s. 9096-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    COVID-19 has impacted education on all levels, with many institutions turning to online formats to deal with the global public health crisis. This study aims to carefully consider participatory risk management, given concerns about the specific impact of COVID-19 upon environmental and outdoor education. An environmental and outdoor education expedition-style university-based field course at the Laponia World Heritage Site provided the context for considering environmental and outdoor education’s response to COVID-19. Whether or how risk could be effectively managed in the unique setting during the COVID-19 pandemic was explored using action research methodology. A combination of systematic instructor observation, student–instructor communication, and surveys to student participants provided the data to consider the research question. Outcomes underscore the critical role of participatory risk management in environmental and outdoor education settings and highlight the concept of interdependence in environmental and outdoor education risk management. In addition, the research provides support for the action research idea of practitioners as researchers.

    Exploring access to nature play in urban parks: resilience, sustainability, and early childhood2020Inngår i: Sustainability, E-ISSN 2071-1050, ISSN ISSN 2071-1050, Vol. 12, nr 12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Nature play is an important component of the development of resilience in early childhood. Nature play is also an element of urban sustainability through a consideration of access to urban nature. From the foundation of access to nature play as a part of both resilience and sustainability considerations, a mixed-method case study was initiated. Spatial analysis, survey outreach, and focus group methodology have been combined to consider whether city parkland provides access for preschools to incorporate nature play, and, further, whether other barriers may exist to limit or prevent the use of city parks for nature play by preschool programs. The results indicate the existence of quality proximate access, but other factors creating barriers for broader application of nature play exist. The results also illustrate the critical role of public access to public parks as part of urban sustainability and the development of resilience in young children. The implications for the use of city parkland for nature play are presented.

    Exploring the role of outdoor recreation to contribute to urban climate resilience2019Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 11, nr 22Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Climate resilience is an important mix of climate mitigation and climate adaptation designed to minimize current and future disruption while promoting opportunity. Given the importance of the regional and local arena for consideration of impacts of climate change trends and needs for climate action, climate resilience in one community, Duluth, Minnesota, is considered. At the core of this project is the climate resilience question: what can we currently be doing in our communities to prepare for projected climate change while simultaneously improving life for current residents and visitors? Given the growing importance of outdoor recreation and nature-based tourism in Duluth, the role this sector may be able to play in climate resilience is considered. Using action research methodology, the research process of adjusting, presenting, and conducting follow-up from a National Oceanic and Atmospheric Administration Climate Adaptation for Coastal Communities workshop is presented. The study takes a unique look at one workshop outcome, a Duluth Parks and Recreation planning tool. Specifically, a resilience checklist is presented as a useful sample outcome of the overall process. Beyond the study community, the role of outdoor recreation to serve climate resilience is explored and affirmed.

    Being and becoming in nature: defining and measuring connection to nature in young children2020Inngår i: International Journal of Early Childhood Environmental Education, ISSN 2331-0464, Vol. 7, nr 3, s. 3-22Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper examines the meaning, assessment, and development of connection to nature (C2N) in two- to five-yearold children. It grows out of a Connection to Nature Workshop organized by the University of Florida, Stanford University, the North American Association for Environmental Education, and the Children and Nature Network to evaluate instruments that measure C2N. Defining and measuring C2N in young children emerged as a current research gap. The workshop was followed by the formation of an Expert Advisory Panel on Early Childhood Nature Connection to address this need. Through semi-structured interviews and narrative responses to a survey, panel participants provided insight on early childhood connection to nature and reviewed existing measures of nature connection for this age group. This paper presents a synthesis of panel ideas. One outcome of the analysis was a detailed description of C2N, highlighting the importance of both quantity and quality of time in nature. Quality time in nature includes opportunities for self-directed exploration, multisensory engagement with nature places, the presence of animals, and the supportive influence of peers and adults. Research implications include recommendations for mixed-method assessment strategies for young children as well as the importance of access to nature for all children.

    Children in nature: sensory engagement and the experience of biodiversity2018Inngår i: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871, Vol. 24, nr 1, s. 13-25Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Given concerns for a severely diminished childhood experience of nature, coupled with alarm for a rapidly diminishing global biodiversity, this article considers the potential for childhood nature experience to be an important part of biodiversity understanding. Findings from two studies are integrated and presented as windows into childhood nature experience to illuminate important aspects of sensory rich learning. In one study from Sweden, semi-structured interviews with adults were conducted and analyzed to explore an understanding of the sensory experience of childhood collecting in nature via participant memories. In the second study, direct observations of children's play and exploration in an outdoor kindergarten in Norway were conducted and analyzed. Bringing these two studies together for shared analysis is useful for investigating biodiversity experience and understanding. Analysis supports the idea that the experience of biodiversity, actual childhood interaction with variation and diversity with living and nonliving items from nature allows children important learning opportunities, inclusive of biodiversity understanding. The results support practical implications for sensory rich environmental education and underscores the practical importance of childhood access to nature.

    Outdoor recreation and place attachment: exploring the potential of outdoor recreation within a UNESCO Biosphere Reserve2017Inngår i: Journal of Outdoor Recreation, ISSN 2213-0780, E-ISSN 2213-0799, Vol. 17, s. 54-63Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study investigates outdoor recreation participation within a multifunctional landscape, a UNESCO Man and Biosphere Reserve. The reserve, the Kristianstad Vattenrike located in southern Sweden, has made a deliberate effort to make the experience of biodiversity possible for residents and visitors. Recreation is a keypart of the biodiversity conservation effort in the area, represented by the infrastructure of the Kristianstad Vattenrike's 21 visitor sites. Given the biosphere reserve context, this study investigates the question of whether there is a relationship between outdoor recreation participation and place attachment. Survey data was collected using concurrent application of multiple sampling strategies including both probability and purposive sampling of local adult residents of the biosphere area. Quantitative analysis showed a significant positive relationship between the level of outdoor recreation participation and place attachment. Qualitative data supported this relationship with more details about place attachment within the studied area. The study confirms a relationship between place attachment and outdoor recreation and provides insight into how the biosphere reserve context supports this relationship. The results of this study show that significant biodiversity management in close conjunction with outdoor recreational opportunity can be achieved and provides opportunities for human engagement and experience of biodiversity.

    Management Implications: This research can help managers design recreational settings that support biodiversity conservation goals. Our research found that:

    • A leading motivation for outdoor recreation participation is nature experience and this motivation can be used by managers to highlight a biodiversity conservation interpretive message in the design of outdoor recreation infrastructure.

    • Providing proximate access to nature based outdoor recreation, to support deliberate and direct experience of biodiversity, is an important component of engaging the public in biodiversity conservation.

    • Recreation proximity alone will not create public engagement in biodiversity conservation. However,proximity as a part of a deliberate institutional design including biodiversity conservation, sustainable development, and logistic support for research and monitoring may be critical for public engagement.

    Childhood collecting in nature: quality experience in important places2019Inngår i: Children's Geographies, ISSN 1473-3285, E-ISSN 1473-3277, Vol. 17, nr 1, s. 118-131Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A need for a more specific understanding of childhood geographies has motivated an investigation of one activity, childhood collecting in nature. This study examined collecting behavior, places of collecting, and the relationship of these places to environmental connectedness in adulthood. Topophilia is presented as a guide to help consider why children collect in nature and to expand upon a limited understanding of collecting behavior. These ideas are explored with a mixed-method design strategy involving surveys and semi-structured interviews with a sample of Swedish university students. Results show collecting in nature to be a widespread, meaningful, and memorable experience in the formative years of participants. Results also demonstrate potential support for topophilia as a way to understand the childhood collecting nature phenomenon. Implications include recognition of the importance of family to support children’s engagement in the natural world and proximate access to nature as a critical aspect of childhood experience.

    Nature’s services and contributions: the relational value of childhood nature experience and the importance of reciprocity2021Inngår i: Frontiers in Ecology and Evolution, E-ISSN 2296-701X, Vol. 9, s. 1-8, artikkel-id 636944Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    People depend on functioning ecosystems to meet human needs and support well-being across the life span. This article considers the interest in ecosystem service valuation, the growing interest in the benefits of nature experience for children, and ways to bridge these perspectives. We focus on embodied childhood nature experiences: the physical and multisensory experiences that intertwine child and nature. Additionally, we highlight the reciprocal quality of nature and child experience relationship as an example of how this relationship goes beyond the instrumental and demonstrates relational value. Underlying this perspective is the belief that children need to be better represented in the perception and action of ecosystem valuation in environmental policy.

    Inspiring the outdoor experience: does the path through a nature center lead out the door?2015Inngår i: Journal of Interpretation Research, ISSN 1092-5872, Vol. 20, nr 1, s. 67-85Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study investigates the visitor experience at a Swedish nature center within aUNESCO biosphere reserve. The question of whether this interpretive facility succeedsin motivating the visitor to get outdoors for a direct experience of nature is explored. Useof the environmental connectedness perspective and concerns about diminished natureexperience support the importance of this study. A number of qualitative methodologiesare used to investigate the research questions, including thought listing, phenomenology,and field observation. Results indicate that this particular nature center generallysucceeded in the goal of inspiring visitors for a direct nature experience. The success inmotivating visitors appears to be a result of a number of key variables, including placebasedexhibitry, access, and personal visitor factors. Given the setting for this study, weconclude that interpretive nature centers have the potential to play an important role inthe re-imagination of urban environments.

    Topophilia and human affiliation with nature2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Objective: The objective of this study is to explore the co-evolutionary foundation for place-based human affiliation with nonhuman nature, and its potential to support sustainable development at the local level. In particular, we analyse the Topophilia Hypothesis, an expansion of the Biophilia Hypothesis which includes also non-living elements in the environment.

    Methods: The study represents a multidisciplinary conceptual analysis of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. 

    Results and Conclusions: The Biophilia Hypothesis has been one of the most important theories of human connectedness with nature, suggesting a genetically based inclination for human affiliation with the biological world. The Topophilia Hypothesis has extended the ideas of Biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. It also puts more emphasis on affiliation processes with the local environment. We propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable development at the local level, and ultimately at the global level. Tendencies of local affiliation may also have implications for multifunctional landscape management, an important area within sustainability research, and we provide some examples of successful landscape management with a strong component of local engagement. Since human affiliation with nonhuman nature is considered an important dimension of environmental concern and support for pro-environmental attitudes, the Topophilia Hypothesis may provide a fruitful ground for a discourse within which scholars from many scientific fields, including human evolution and humanistic geography, can participate.

    From environmental connectedness to sustainable futures: topophilia and human affiliation with nature2015Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 7, nr 7, s. 8837-8854Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human affiliation with nonhuman nature is an important dimension of environmental concern and support for pro-environmental attitudes. A significant theory of human connectedness with nature, the Biophilia Hypothesis, suggests that there exists a genetically based inclination for human affiliation with the biological world. Both support and challenge to the Biophilia Hypothesis are abundant in the literature of environmental psychology. One response that both challenges and builds upon the Biophilia Hypothesis is the Topophilia Hypothesis. The Topophilia Hypothesis has extended the ideas of biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. While the Topophilia Hypothesis is a new idea, it is built upon long-standing scholarship from humanistic geography and theories in human evolution. The Topophilia Hypothesis expands previous theory and provides a multidisciplinary consideration of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. Support for this possible co-evolutionary foundation for place-based human affiliation with nonhuman nature is explored from multiple vantage points. We raise the question of whether this affiliation may have implications for multifunctional landscape management. Ultimately, we propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable efforts at the local level with implications for the global.

    Pre-service early childhood educator experience in a UNESCO Biosphere Reserve2021Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 13, nr 8, s. 1-20, artikkel-id 4231Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There has been significant interest in the values and benefits of early childhood nature experiences on children’s well-being and development. One aspect of studying the exposure of children to nature that requires more focus is the role played by early childhood educators. In particular, there is a need for early childhood environmental education training for pre-service educators. This study will explore the use of a UNESCO Biosphere Reserve as an outdoor classroom for early childhood environmental education pre-service professionals. Exploratory quantitative and qualitative descriptive data from a series of three short surveys (pre/post/delayed post) provide a basic overview of pre-service teacher perspectives, experiences, and outcomes of an environmental education intervention. The results indicate that the participating pre-service educators had little to no familiarity with the environmental concepts or the biosphere reserve site before participation in the intervention. The post-intervention and delayed post-intervention results show that pre-service educators perceived that their understanding of the concept had improved. The results also show a perception of the positive role that biosphere reserve sites can play in early childhood education. Three critical implications emerged from the overall quantitative and qualitative results: (1) specific support should be given for early childhood environmental education training; (2) biosphere reserve functions provide support for efforts to improve connections to nature; (3) early childhood education has the potential to support the broadening of the biosphere reserve audience.

    Covid-19 and outdoor recreation management: Increased participation, connection to nature, and a look to climate adaptation2021Inngår i: Journal of Outdoor Recreation, ISSN 2213-0780, E-ISSN 2213-0799, Vol. 36, s. 100457-100457, artikkel-id 100457Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Outdoor recreation management perspectives were investigated based on the general perception of increased public outdoor recreation participation during the Covid-19 pandemic and supported by survey research at local, regional, and national levels in Sweden. There is an interest in how outdoor recreation professionals perceived outdoor recreation by the public during the pandemic and whether professionals could identify specific implications from the Covid-19/outdoor recreation experience. Climate adaptation literature supports the idea that current global challenge coupled with projections for ongoing challenge requires a pro-active approach; this turn to climate adaptation for potential consideration or guidance is based on characteristics that the Covid-19 pandemic shares with climate change. Outdoor recreational professionals' review of a recent public survey and subsequent semi-structured interviews with this group were conducted to obtain outdoor recreation professionals' detailed perceptions on survey outcomes. Results show that the professionals confirm a rapid and significant increase in outdoor recreation participation. Further, professionals identified critical trends in the increase of new or inexperienced outdoor recreation participants. A positive and proactive list of implications emerged as themes of the interviews. A review and synthesis of the themes support the national goals for outdoor recreation in Sweden. Further, results indicate a current opportunity for outdoor recreation to address concerns for diminishing nature experience and support connectedness to nature. The connectedness to nature outcome further strengthens the comparison with climate adaptation strategy given the potential relationship between connectedness to nature and pro-environmental behavior.

    Fostering incidental experiences of nature through green infrastructure planning2017Inngår i: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 46, nr 7, s. 717-730Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Concern for a diminished human experience of nature and subsequent decreased human well-being is addressed via a consideration of green infrastructure's potential to facilitate unplanned or incidental nature experience. Incidental nature experience is conceptualized and illustrated in order to consider this seldom addressed aspect of human interaction with nature in green infrastructure planning. Special attention has been paid to the ability of incidental nature experience to redirect attention from a primary activity toward an unplanned focus (in this case, nature phenomena). The value of such experience for human well-being is considered. The role of green infrastructure to provide the opportunity for incidental nature experience may serve as a nudge or guide toward meaningful interaction. These ideas are explored using examples of green infrastructure design in two Nordic municipalities: Kristianstad, Sweden, and Copenhagen, Denmark. The outcome of the case study analysis coupled with the review of literature is a set of sample recommendations for how green infrastructure can be designed to support a range of incidental nature experiences with the potential to support human well-being.

    Perceptions of the ecosystem services concept: opportunities and challenges in the Swedish municipal context2016Inngår i: Ecosystem Services, ISSN 2212-0416, E-ISSN 2212-0416, Vol. 17, s. 123-130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A current focus of ecosystem services (ES) implementation is on the municipal level of government where international and national legislation and policies have to be translated into practice. Given this focus, an understanding of perceptions within municipalities of the ES concept is crucial to support the implementation process. Against this background, this paper examines the perceptions of Swedish municipal stakeholders for the ES concept. A 2013 Swedish federal mandate that states that the values of ecosystem services should be considered in relevant decision-making processes, provides a timely context. Current perceptions, preconditions and awareness are explored via interviews and analyses. The results show that the views on the ecosystem services concept and its usefulness are generally very positive. Conceptual knowledge use is perceived as important as is the recognition of monetary valuation of ES. However, clarification of the distinction between implicit and explicit use of the concept by stakeholders is needed. Finally, results indicate that a deeper understanding of monetary valuation of ecosystem services by municipal staff members is connected with a more critical view on monetary valuation. It is concluded that detailed and clear definitions and guidelines are needed in order to support the process of implementing ES in municipalities.

    Nature to place: rethinking the environmental connectedness perspective2014Inngår i: Journal of Environmental Psychology, ISSN 0272-4944, E-ISSN 1522-9610, Vol. 40, nr December, s. 198-205Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The environmental connectedness perspective posits that direct encounter with generalized, or non-specific “nature,” leads to environmental connectedness and subsequent pro-environmental behavior. This article examines this perspective and proposes a place-based application of the nature encounter-environmental behavior relation. An empirical study using data from a national survey on outdoor recreation and nature-based tourism is presented. Results show a minimal relationship between measures of environmental connectedness and self-reports of environmental behavior. The following examination of the environmental connectedness perspective reveals that environmental connectedness is rooted in a material/objective perspective, neglecting the human domain of perceptions, values, and representations. The environment as “nature” is portrayed as a geographically undefined agent with the inherent power to change human attitudes and behavior. Based on this, the article concludes with a proposed replacement of the elusive concept of nature for the relational concept of place.

    Sequence analysis of the DNA-repair gene rad51 in the tardigrades Milnesium cf. tardigradum, Hypsibius dujardini and Macrobiotus cf. harmsworthi2013Inngår i: Journal of limnology, ISSN 1129-5767, E-ISSN 1723-8633, Vol. 72, nr s1, s. 80-91Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tardigrades are known for being resistant to extreme conditions, including tolerance to ionising and UV radiation in both the hydratedand the dehydrated state. It is known that these factors may cause damage to DNA. It has recently been shown that single and double DNAstrand breaks occur when tardigrades are maintained for a long time in the anhydrobiotic state. This may suggest that perhaps tardigrades rely on efficient DNA repair mechanisms. Among all proteins that comprise the DNA repair system, recombinases such as RecA or Rad51 have a very important function: DNA exchange activity. This enzyme is used in the homologous recombination and allows repair of thedamaged strand using homologous non-damaged strands as a template. In this study, Rad51 induction was evaluated by western blot in Milnesium cf. tardigradum, after exposure to gamma radiation. The Rad51 protein was highly induced by radiation, when compared to the control. The rad51 genes were searched in three tardigrades: Milnesium cf. tardigradum, Hypsibius dujardini and Macrobiotus cf. harmsworthi. The gene sequences were obtained by preparing and sequencing transcriptome libraries for H. dujardini and M. cf. harmsworthi and designing rad51 degenerate primers specific for M. cf. tardigradum. Comparison of Rad51 putative proteins from tardigrades with other organisms showed that they are highly similar to the corresponding sequence from the nematode Trichinella spiralis. A structure-based sequence alignment from tardigrades and other organisms revealed that putative Rad51 predicted proteins from tardigrades contain the expected motifs for these important recombinases. In a cladogram tree based on this alignment, tardigrades tend to cluster together suggesting that they have selective differences in these genes that make them diverge between species. Predicted Rad51 structures from tardigrades were also compared with crystalline structure of Rad51 in Saccharomyces cerevisiae. These results reveal that S. cerevisiae Rad51 structure is very similar to that of the three analysed tardigrades. On the other hand the predicted structure of Rad51 from M. cf. harmsworthi and H. dujardini are closer related to each other, than each of them to that of M. cf. tardigradum.

    Effects of ionizing radiation on embryos of the tardigrade Milnesium cf. tardigradum at different stages of development2013Inngår i: PLOS ONE, E-ISSN 1932-6203, Vol. 8, nr 9, s. e72098-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tardigrades represent one of the most desiccation and radiation tolerant animals on Earth, and several studies havedocumented their tolerance in the adult stage. Studies on tolerance during embryological stages are rare, but differentialeffects of desiccation and freezing on different developmental stages have been reported, as well as dose-dependent effectof gamma irradiation on tardigrade embryos. Here, we report a study evaluating the tolerance of eggs from theeutardigrade Milnesium cf. tardigradum to three doses of gamma radiation (50, 200 and 500 Gy) at the early, middle, andlate stage of development. We found that embryos of the middle and late developmental stages were tolerant to all doses,while eggs in the early developmental stage were tolerant only to a dose of 50 Gy, and showed a declining survival withhigher dose. We also observed a delay in development of irradiated eggs, suggesting that periods of DNA repair might havetaken place after irradiation induced damage. The delay was independent of dose for eggs irradiated in the middle and latestage, possibly indicating a fixed developmental schedule for repair after induced damage. These results show that thetolerance to radiation in tardigrade eggs changes in the course of their development. The mechanisms behind this patternare unknown, but may relate to changes in mitotic activities over the embryogenesis and/or to activation of responsemechanisms to damaged DNA in the course of development.

    Movements, home-range size and habitat selection of mallards during autumn migration2014Inngår i: PLOS ONE, E-ISSN 1932-6203, Vol. 9, nr 6, s. e100764-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The mallard (Anas platyrhynchos) is a focal species in game management, epidemiology and ornithology, but comparably little research has focused on the ecology of the migration seasons. We studied habitat use, time-budgets, home-range sizes, habitat selection, and movements based on spatial data collected with GPS devices attached to wild mallards trapped at an autumn stopover site in the Northwest European flyway. Sixteen individuals (13 males, 3 females) were followed for 15-38 days in October to December 2010. Forty-nine percent (SD = 8.4%) of the ducks' total time, and 85% of the day-time (SD = 28.3%), was spent at sheltered reefs and bays on the coast. Two ducks used ponds, rather than coast, as day-roosts instead. Mallards spent most of the night (76% of total time, SD = 15.8%) on wetlands, mainly on alvar steppe, or in various flooded areas (e.g. coastal meadows). Crop fields with maize were also selectively utilized. Movements between roosting and foraging areas mainly took place at dawn and dusk, and the home-ranges observed in our study are among the largest ever documented for mallards (mean = 6,859 ha; SD = 5,872 ha). This study provides insights into relatively unknown aspects of mallard ecology. The fact that autumn-staging migratory mallards have a well-developed diel activity pattern tightly linked to the use of specific habitats has implications for wetland management, hunting and conservation, as well as for the epidemiology of diseases shared between wildlife and domestic animals.

    Does influenza A virus infection affect movement behaviour during stopover in its wild reservoir host?2016Inngår i: Royal Society Open Science, E-ISSN 2054-5703, Vol. 3, nr 2, artikkel-id 150633Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The last decade has seen a surge in research on avian influenza A viruses (IAVs), in part fuelled by the emergence, spread and potential zoonotic importance of highly pathogenic virus subtypes. The mallard (Anas platyrhynchos) is the most numerous and widespread dabbling duck in the world, and one of the most important natural hosts for studying IAV transmission dynamics. In order to predict the likelihood of IAV transmission between individual ducks and to other hosts, as well as between geographical regions, it is important to understand how IAV infection affects the host. In this study, we analysed the movements of 40 mallards equipped with GPS transmitters and three-dimensional accelerometers, of which 20 were naturally infected with low pathogenic avian influenza virus (LPAIV), at a major stopover site in the Northwest European flyway. Movements differed substantially between day and night, as well as between mallards returning to the capture site and those feeding in natural habitats. However, movement patterns did not differ between LPAIV infected and uninfected birds. Hence, LPAIV infection probably does not affect mallard movements during stopover, with high possibility of virus spread along the migration route as a consequence.

    Äta insekter: finns det några hälsorisker?2019Inngår i: Nutritionsfakta, Vol. decemberArtikkel i tidsskrift (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    En tidigare publicerad artikel i Nutritionsfakta har visat på hälso- och hållbarhetsfördelar med att äta insekter. Finns det då några hälsorisker med att äta insekter? När det gäller kemiska risker är dessa små, förutsatt att producenten har kontroll på fodrets tungmetallinnehåll. Bakterier och andra mikroorganismer behöver kontrolleras noga, men inga tydliga risker finns här heller. Personer med skaldjursallergier bör dock vara försiktiga med insekter. Generellt motsvarar riskerna de som gäller för andra animaliska livsmedel, och samma typ av kontrollprogram bör finnas. Dock behövs mer forskning inom området. Kött från nöt, svin och fjäderfä har studerats under lång tid; det är dags att låta forskningen kring insekter som mat börja ta igen det försprånget.

    Phobos LIFE (Living Interplanetary Flight Experiment).2019Inngår i: Astrobiology, ISSN 1531-1074, E-ISSN 1557-8070Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Planetary Society's Phobos Living Interplanetary Flight Experiment (Phobos LIFE) flew in the sample return capsule of the Russian Federal Space Agency's Phobos Grunt mission and was to have been a test of one aspect of the hypothesis that life can move between nearby planets within ejected rocks. Although the Phobos Grunt mission failed, we present here the scientific and engineering design and motivation of the Phobos LIFE experiment to assist with the scientific and engineering design of similar future experiments. Phobos LIFE flew selected organisms in a simulated meteoroid. The 34-month voyage would have been the first such test to occur in the high-radiation environment outside the protection of Earth's magnetosphere for more than a few days. The patented Phobos LIFE "biomodule" is an 88 g cylinder consisting of a titanium outer shell, several types of redundant seals, and 31 individual Delrin sample containers. Phobos LIFE contained 10 different organisms, representing all three domains of life, and one soil sample. The organisms are all very well characterized, most with sequenced genomes. Most are extremophiles, and most have flown in low Earth orbit. Upon return from space, the health and characteristics of organisms were to have been compared with controls that remained on Earth and have not yet been opened.

    Effects of biopellets composed of microalgae and fungi on cadmium present at environmentally relevant levels in water2017Inngår i: International journal of phytoremediation, ISSN 1522-6514, E-ISSN 1549-7879, Vol. 19, nr 5, s. 500-504Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Removal of cadmium (Cd) present at low levels (1 µg L−1) in water was investigated using three different microorganism treatments: the microalga Chlorella vulgaris, the fungus Aspergillus niger and for the first time biopellets composed of C. vulgaris and A. niger. After 5 days, all microorganism treatments resulted in significantly lower Cd concentrations compared with the control. Biopellets treatment resulted in significantly lower pH values than other microorganism treatments, indicating that the biopellets should be investigated further for their water treatment capacity, since pH is a factor affecting the fate of numerous pollutants in water. Use of biopellets as a method to simplify harvesting of microalgae from water is also suggested.

    Effects of biopellets composed of microalgae and fungi on pharmaceuticals present at environmentally relevant levels in water2016Inngår i: Ecological Engineering: The Journal of Ecotechnology, ISSN 0925-8574, E-ISSN 1872-6992, Vol. 91, s. 169-172Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Removal of seven pharmaceuticals (acetaminophen, carbamazepine, diclofenac, metoprolol, naproxen, ranitidine and sulfamethoxazole) from water was investigated using three different microbial treatments with: (1) the microalga Chlorella vulgaris, (2) the fungus Aspergillus niger and (3) biopellets composed of both microorganisms. The three-day experiment was performed under laboratory conditions and pharmaceuticals were spiked at the environmentally relevant concentration of 10 mu g L-1. The biopellets and fungal treatments resulted in significantly lower ranitidine concentration compared with the initial value. Also, treatment with biopellets resulted in significantly lower final ranitidine concentrations compared to those found after control and microalgal treatments. Low removal rates were obtained for other substances, possibly because the amount of microbial biomass used was 16-500-fold lower than that normally used in activated sludge processes in wastewater treatments plants. Thus, the pharmaceutical removal potential, elimination potential and performance of biopellets should be further investigated at higher biomass concentrations. (C) 2016 Published by Elsevier B.V.

    Attenuation of pharmaceutical substances: phytoremediation using constructed wetlands2018Inngår i: 13th Society of wetland scientists (SWS) Europe chapter meeting: management of wetland ecosystem services: issues, challenges and solutions, 2018, s. 19-22Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Introduction: Currently, wastewater treatment plants (WWTPs) do not efficiently remove pharmaceutical substances (PS). Thus, such substances are now frequently found in aquatic ecosystems worldwide. Also, concentrations of some PS in treated effluents exceed Environmental Quality Standards proposed by EU legislation. One resource-efficient option for increasing PS removal in WWTP effluents is to use constructed wetlands (CWs) as an attenuation step (Breitholtz et al. 2012; Li et al. 2014). However, very little research has been done on how to maximize the PS attenuation capacity of CWs. Therefore, a project with the aim to investigate reduction of different pharmaceutical substances in CWs with different vegetation compositions and water depths, was performed at the Experimental Wetland Area (EVA) located 20 km north of Halmstad, Sweden.

    On the road to 'research municipalities': analysing transdisciplinarity in municipal ecosystem services and adaptation planning2018Inngår i: Sustainability Science, ISSN 1862-4065, E-ISSN 1862-4057, Vol. 13, nr 3, s. 765-784Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution-oriented approaches that can tackle complex sustainability challenges, such as biodiversity loss, pollution, and climate-related hazards. In this context, city governments' engagement in transdisciplinarity is generally seen as a key condition for societal transformation towards sustainability. However, empirical evidence is rare. This paper presents a self-assessment of a joint research project on ecosystem services and climate adaptation planning (ECOSIMP) undertaken by four universities and seven Swedish municipalities. We apply a set of design principles and guiding questions for transdisciplinary sustainability projects and, on this basis, identify key aspects for supporting university-municipality collaboration. We show that: (1) selecting the number and type of project stakeholders requires more explicit consideration of the purpose of societal actors' participation; (2) concrete, interim benefits for participating practitioners and organisations need to be continuously discussed; (3) promoting the 'inter', i.e., interdisciplinary and inter-city learning, can support transdisciplinarity and, ultimately, urban sustainability and long-term change. In this context, we found that design principles for transdisciplinarity have the potential to (4) mitigate project shortcomings, even when transdisciplinarity is not an explicit aim, and (5) address differences and allow new voices to be heard. We propose additional guiding questions to address shortcomings and inspire reflexivity in transdisciplinary projects.

    Landscape, climate, sea-level variations and human living conditions in a coastal area of western Blekinge on the Baltic sea between 11600 cal BP and AD 1000: E22- Sölvesborg-Stensnäs-project members 20142014Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The aim of the project has been to reveal the living conditionsfor humans in a coastal area of the Baltic sea during thirteen thousand years and to study the implications of variations in climate, sea-level and landscape changes. The archaeological ex- cavations, well integrated with paleoecological studies, along a twenty kilometer new road-built between Sölvesborg and Stensnäs has resulted in unique findings which shed new light on to the human history in southern Scandinavia and adjust- ment of the sea-level curve in western Blekinge. Time periods from early mesolithic, neolithic, bronze age until late iron age are well represented at the sites along the former bay and lake Vesan. Macrofossil analysis of the plant material at the archae- ological sites has revealed the food resources, burial gifts and given a glimpse of the local environment. Sediment cores from the center and near shore of former lake Vesan has given the opportunity to reconstruct the aquatic conditions and vegeta- tion in the surrounding landscape based on analysis of diatoms, pollen, macrofossils and carbon content. The vast number of radiocarbon dates of the archaeological material from various altitudes at the sites has enabled adjustment of the sea-level curve especially during Ancylus-, Littorina transgressions and aregression around 8.2 ka.

    The effect of nanoparticles on the structure and enzymatic activity of human carbonic anhydrase I and II2020Inngår i: Molecules, ISSN 1431-5157, E-ISSN 1420-3049, Vol. 25, nr 19Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human carbonic anhydrases (hCAs) belong to a well characterized group of metalloenzymes that catalyze the conversion of carbonic dioxide into bicarbonate. There are currently 15 known human isoforms of carbonic anhydrase with different functions and distribution in the body. This links to the relevance of hCA variants to several diseases such as glaucoma, epilepsy, mountain sickness, ulcers, osteoporosis, obesity and cancer. This review will focus on two of the human isoforms, hCA I and hCA II. Both are cytosolic enzymes with similar topology and 60% sequence homology but different catalytic efficiency and stability. Proteins in general adsorb on surfaces and this is also the case for hCA I and hCA II. The adsorption process can lead to alteration of the original function of the protein. However, if the function is preserved interesting biotechnological applications can be developed. This review will cover the knowledge about the interaction between hCAs and nanomaterials. We will highlight how the interaction may lead to conformational changes that render the enzyme inactive. Moreover, the importance of different factors on the final effect on hCAs, such as protein stability, protein hydrophobic or charged patches and chemistry of the nanoparticle surface will be discussed.

    The success of cooperative strategies in the iterated prisoner's dilemma and the chicken game2007Inngår i: Scalable Computing: Practice and Experience: Scientific International Journal for Parallel and Distributed Computing, ISSN 1895-1767, Vol. 8, nr 1, s. 87-100Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The prisoner's dilemma has evolved into a standard game for analyzing the success of cooperative strategies in repeated games. With the aim of investigating the behavior of strategies in some alternative games we analyzed the outcome of iterated games for both the prisoner's dilemma and the chicken game. In the chicken game, mutual defection is punished more strongly than in the prisoner's dilemma, and yields the lowest fitness. We also ran our analyses under different levels of noise. The results reveal a striking difference in the outcome between the games. Iterated chicken game needed more generations to find a winning strategy. It also favored nice, forgiving strategies able to forgive a defection from an opponent. In particular the well-known strategy tit-for-tat has a poor successrate under noisy conditions. The chicken game conditions may be relatively common in other sciences, and therefore we suggest that this game should receive more interest as a cooperative game from researchers within computer science.
