    Anaesthesia and handling stress effects on pigmentation and monoamines in Arctic charr2017Inngår i: Environmental Biology of Fishes, ISSN 0378-1909, E-ISSN 1573-5133, Vol. 100, nr 5, 471-480 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Stress responsiveness differs between individuals and is often categorized into different stress coping styles. Using these stress coping styles for selection in fish farming could be beneficial, since stress is one main factor affecting welfare. In Arctic charr (Salvelinus alpinus) carotenoid pigmentation is associated with stress responsiveness and stress coping styles. Thus this could be an important tool to use for selection of stress resilient charr. However, anaesthetics seem to affect carotenoid pigmentation, and it would be better if the method for selection could be implemented during normal maintenance, which usually includes anaesthetics. Therefore, this study investigated how the use of anaesthetics affected carotenoid pigmentation, i.e. number of spots, over time compared to no-anaesthetic treatment. Additionally, the stress indicators monoamines and glucocorticoids were investigated. The results indicate that the anaesthetic MS-222 affects number of spots on the right side. This anaesthetic also increased dopaminergic activity in the telencephalon. Both brain dopaminergic and serotonergic activity was associated with spottiness. Further, behaviour during anaesthetization was associated with spots on the left side, but not the right side. Repetition of the same treatment seemed to affect spot numbers on the right side. In conclusion, this study shows that inducing stress in charr affects the carotenoid spots. Thus, it is possible to use anaesthetics when evaluating spottiness although careful planning is needed.

    Allocation of Fishing Rights in the NEA: Discussion paper2015Bok (Annet vitenskapelig)
    Abstract [en]

    This discussion paper aims to initiate an informed debate in the Nordic countries and elsewhere on how to allocate the trans-boundary fish stocks in the North East Atlantic in the future and how to resolve possible allocation conflicts. The paper maps the current legal framework and international fisheries agreements in the North East Atlantic Ocean which forms the basis for allocation agreements. It considers the relevance of the biological status of the fish stocks and the economic situation of the coastal states in the area for the allocation of fishing rights and further proposes a dynamic allocation methodology and a decision making process including the handling of allocation conflicts. The paper is compiled by an inter-disciplinary Nordic group of fisheries experts.

    Small-Scale Fisheries Governance: Broadening Perspectives on Markets, Relationships and Benefits in Seafood Trade2016Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This licentiate adresses the relative ambiguity surounding benefit flows from small-scale fisheries seafood trade with a specific focus on how they may be impacted by market and social stuctures. Small-scale fishery governenace has previously taken a narrowly approach to sustainability. Focused on managing fishing activities, economic-led market interventions and overlooking the embededness of the fishers within a broader social structure. Also failing to address fisheries as interlinked social-ecological systems where feedbacks between the two can impact future sustainability. The larger PhD project takes a step towards combining these two out-of-focus areas by taking a systems perspective, through a Value Chain approach, to fisheries governance, associated market influences and the consequent benefit flows from marine ecosystem services. This licentiate begins by unpacking dynamics within the social realm that may impact benefit flows and ultimately resource extraction decisions, potentially contributing to feedbacks from the marine ecosystem. Research uses mixed-methods and is case-orientated with sites across two tropical marine small-scale fisheries in Zanzibar and the Philippines. Results present two market environments with distinct structures, conduct, reciprocity systems and notably, gender roles. However both systems experience economic transactions underlain by broader social relations and binds. These various features manifest themselves in different, yet often unexpected, ways through income equalities, distributions and reciprocal networks of fishers and trading actors. Once a broadened and diversified view of the SSF trading environment is appropriated, it is clear that benefit flows are impacted by various contextual features (e.g. gender, transaction forms and buyer types). Governance-related research or interventions should incorporate undervalued local attributes such as cultural characteristics, social relationships and market participation as they play a role in who benefits from seafood trade. Thus If governance is to be improved for sustainably increasing food and livelihood security it is necessary to unpack these benefit flow mechanisms and, in particular, the local social dynamics that mediate fishers’ everyday interplay with the marine ecosystem. Future steps include the aim to identify potential social-ecological feedbacks between the disentangled market environments and the local marine ecosystems as a result of interactions in SSF trade.

    Direct experience and attitude change towards bears and wolves2015Inngår i: Wildlife Biology, ISSN 0909-6396, E-ISSN 1903-220X, Vol. 21, nr 3, 131-137 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Understanding how changes in the sizes of large carnivore populations affect the attitudes of the public is vital in order to mitigate social conflicts over large carnivore management issues. Using data from two Swedish postal surveys in 2004 and 2009, we examined the probable social effects of a continued increase in the Swedish populations of bear and wolf by comparing levels of direct experience of bears and wolves with public attitudes towards these animals. We report an increase in direct experience of bears and wolves, lower levels of acceptance of the existence of these animals, and a lower degree of support for the policy goals of both species in 2009 compared to 2004. We also find that these changes are more prominent in areas with local carnivore populations than in other areas of Sweden. Our results imply that attitudes towards bears and wolves are likely to become more negative as populations continue to grow. The uneven distributions of the carnivore populations are likely to generate more frequent social conflicts in the future as they could cause an increase in the attitudinal divide between those members of the Swedish public who have had direct experiences of carnivores and those who have not.

    Driving behaviour responses to a moose encounter, automatic speed camera, wildlife warning sign and radio message determined in a factorial simulator study2016Inngår i: Accident Analysis and Prevention, ISSN 0001-4575, E-ISSN 1879-2057, Vol. 86, 229-238 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In a driving simulator study, driving behaviour responses (speed and deceleration) to encountering a moose, automatic speed camera, wildlife warning sign and radio message, with or without a wildlife fence and in dense forest or open landscape, were analysed. The study consisted of a factorial experiment that examined responses to factors singly and in combination over 9-km road stretches driven eight times by 25 participants (10 men, 15 women). The aims were to: determine the most effective animal–vehicle collision (AVC) countermeasures in reducing vehicle speed and test whether these are more effective in combination for reducing vehicle speed; identify the most effective countermeasures on encountering moose; and determine whether the driving responses to AVC countermeasures are affected by the presence of wildlife fences and landscape characteristics. The AVC countermeasures that proved most effective in reducing vehicle speed were a wildlife warning sign and radio message, while automatic speed cameras had a speed-increasing effect. There were no statistically significant interactions between different countermeasures and moose encounters. However, there was a tendency for a stronger speed-reducing effect from the radio message warning and from a combination of a radio message and wildlife warning sign in velocity profiles covering longer driving distances than the statistical tests. Encountering a moose during the drive had the overall strongest speed-reducing effect and gave the strongest deceleration, indicating that moose decoys or moose artwork might be useful as speed-reducing countermeasures. Furthermore, drivers reduced speed earlier on encountering a moose in open landscape and had lower velocity when driving past it. The presence of a wildlife fence on encountering the moose resulted in smaller deceleration.

    Kollisioner och olyckor med rådjur i Sverige under 10 år (2003–2012): variation i tid, geografi och kostnader2014Rapport (Annet vitenskapelig)
    Abstract [sv]

    Målen med detta projekt var att skapa en 10-årig översikt över antalet rådjurskollisioner i Sverige och olyckornas variation i tid, geografi och kostnader, både avseende egendomsskador och personskadeolyckor. Olycksstatistik från NVR, Nationella viltolycksrådet (kollisioner), Strada (personskadeolyckor i Swedish Traffic Accident Data Acquisition) och Ofelia (system för järnväg) har använts. Resultaten visar att antalet rådjurskollisioner ökat under 10-årsperioden. Totalt antal rådjursolyckor som blivit inrapporterade under åren 2003–2012 är 306 267 (egendomsskador och personskadeolyckor) medan antalet omkomna och skadade personer i dessa olyckor är 2 752. Ökningen i antalet rådjurskollisioner har varit betydligt större i de nordligaste länen och Gotland. Antalet rådjurskollisioner är betydligt fler under försommaren (maj–juni) och tidigt på vintern (oktober–december), medan antalet personskadeolyckor med rådjur är högst under sommaren. Antalet rådjurskollisioner varierar under dygnet men flest kollisioner och olyckor sker under morgon och kväll för både egendomsskador och personskadeolyckor. För antalet omkomna i olyckor med rådjur inblandade är antalet dubbelt så stort än de officiellt rapporterade antalen, medan antalet svårt skadade är minst 177 % högre än de officiella siffrorna. Det är troligt att den officiella statistiken även underskattar antalet dödade och skadade från övriga viltslag såsom älg, hjort och vildsvin. Denna studie visar att totala kostnaderna för rådjurskollisioner och rådjursolyckor 2012 överstiger 1 miljard kronor varav cirka 70 % är kostnader för egendomsskador.

    Effects of muscle lipid concentration on wild and hatchery brown trout (Salmo trutta) smolt migration2012Inngår i: Canadian Journal of Fisheries and Aquatic Sciences, ISSN 0706-652X, E-ISSN 1205-7533, Vol. 69, nr 1, 1-12 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Annually, hatchery programs are releasing millions of salmonid smolts into the Baltic Sea. Recent estimations indicate a decline in smolt sea survival, questioning the ecological and socioeconomic values of these programs. Concurrently, hatchery smolts have increased in lipid concentration. Salmonids display partial migration, and it is suggested that the ratio of migrants/residents is affected by individual smolt energetic status. To test whether the increased energetic status of hatchery smolts could explain the noted decrease in survival, we released wild trout smolts, conventional hatchery smolts, and hatchery smolts of low energetic status into a Baltic Sea river. Using telemetry, we obtained data on the number of successful migrants, their swimming speed, and diel migratory behaviour. A much lower proportion of conventional smolts (30%) successfully migrated to the coast. No difference was found between wild (74%) and hatchery smolts of low energetic status (64%). Furthermore, conventional smolts migrated slower and showed no diel migratory pattern. The results are of high relevance for hatchery programs producing partially migrating fish.

    Mount Fuji’s Listing as a Cultural World Heritage Site: Challenges of Fragmented Governance2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Heritage management is often fragmented, and Japan is no exception with considerable horizontal fragmentation between municipal, prefectural and central government agencies. For example, the Ministry of Environment (MoE) is the legally-designated administrator of national parks but their institutional objectives are often inconsistent with those of other state agencies, such as the MAFF (a significant landowner) and MEXT (responsible for cultural heritage). This poses serious challenges for management of large mixed type heritage where objects are not easily classified as natural or cultural. Mount Fuji, UNESCO World Cultural Heritage since 2013, consists of a serial nomination of sites within Fuji-Hakone-Izu National Park that overlaps with the administrative territory of 15 municipalities and two prefectures. This complex combination of multiple stakeholders can have the unintended side-effect of pitting government agencies against each other, and against private stakeholders such as mountain huts who maintain certain trails. The nomination process was challenged by the legislation and established procedures that struggle to accommodate natural landscapes functioning as cultural objects of worship and art. The fragmented management style was typified by subordination to business interests and avoidance of disrupting the status quo. One solution was to focus on sites that were already listed under national law. Site maintenance is typically split between several departments and institutions that are subjected to regular rotation of human resources. 13 However, the UNESCO listing process opened a window for greater cooperation. After tentative listing in 2007, a cross-cutting committee was formed in 2009 to standardize place names, and remove unnecessary or inferior trail signs. The simplified system of colour-coded, multi-lingual signs along 4 main trails symbolizes how the ‘carrot’ of UNESCO inscription provided an incentive to galvanize diverse stakeholders into collaborative action, but it is difficult to envisage how the momentum can maintain cross-cutting partnerships now that inscription has been achieved.

    Abstract [en]

    During the twenty-first century, large carnivores have increased in human dominated landscapes after being extinct or nearly extinct. This has resulted in increasing numbers of livestock killed by large carnivores. The intent of this paper is to give a land use-historical perspective on the recent livestock-carnivore conflict in boreal Sweden. More specifically we address: (1) depredation risks (livestock killed by carnivores) and (2) local knowledge of how to protect livestock from predation and whether it survived among pastoralists until the present. This study provides numeric information on carnivores, livestock and depredation, combined with oral information from summer farmers about livestock protection. We compare recent (since 1998) and historical (late nineteenth century) depredation rates in two Swedish counties. In Dalarna recent depredation rates are higher than historical rates while the opposite pattern is seen in Jamtland. Recent depredation rates in Dalarna are twice the recent rates in Jamtland, in contrast to the historical situation. Recent and historical depredation rates are of the same order. Summer farmers traditionally graze their livestock in forested areas where carnivores reside. Interviews show that traditional knowledge of how to protect livestock from carnivores was lost during the twentieth century, but recently new knowledge has developed leading to changes in summer farming practices. The carnivore-livestock situation today differs from the historical situation, not so much in levels of depredation, but mainly regarding the possibilities of farmers to face challenges associated with increasing carnivore populations.

    Conflict resolution through ecosystem-based management: the case of Swedish moose management2013Inngår i: International Journal of the Commons, ISSN 1875-0281, E-ISSN 1875-0281, Vol. 7, nr 2, 549-570 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Swedish moose (Alces alces) management has over the years transformed from a situation similar to what Hardin (1968) defined as a tragedy of the commons – i.e. where open access and unrestricted demands lead to over-exploitation – into a situation characterized by an abundance of moose. While high numbers of moose are preferred by hunters, they damage forests through grazing, causing conflicts between hunters and forest owners. In an attempt to resolve these disputes, the Swedish government is introducing a new local ecosystem-based management system. This paper analyzes this shift from managing a single resource to the broader perspective of ecosystem management and discusses to what extent it will contribute to conflict resolution. The results suggest that some of the problems highlighted may be solved through the implementation of an ecosystem management system. However, several challenges remain to be tackled, such as how to establish robust partnerships between forest owners and hunters for managing moose on land with a fragmented property rights structure. This can lead to different and conflicting objectives and, consequently, difficulties in reaching collective action.

    Large-scale releases of native species: the mallard as a predictive model system2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed. The mallard (Anas platyrhynchos) is the most numerous and widespread duck in the world and a flagship in wetland conservation. It is also an important game species which is heavily restocked for hunting purposes, especially in Europe where over three million ducklings are released every year. Because of its hunted status, its abundance, and the number of released individuals, it can serve as a model species to study effects of releases, both for conservation and restocking for hunting, on wild populations. In this thesis the status of the mallard was assessed in the Nordic countries and the effects of releases on the wild populations were studied by mining historical ringing data, comparing morphology of present-day wild, farmed, and historical mallards, and analyzing phylogeography of wild and farmed mallards in Europe. The status of the mallard population in the Nordic countries are generally good, however, a joint effort of European countries is needed to monitor and manage the population. A significant difference between wild and farmed mallards concerning longevity, migration, bill morphology and genetic structure was also found, together with signs of cryptic introgression of farmed genotypes in the wild population with potential fitness reduction as a result. The effect is however limited by that only a fraction of released farmed mallards reach the breeding season due to low survival. A natural captive environment is crucial to keep individuals wild-like with high survival rates after release. However, with an introgression of potentially maladapted farmed genotypes leading to a reduction in fitness, a low survival of released mallards would favor the wild population. A legislative change regarding obligation to report numbers, provenance, and release sites of farmed mallard should be considered, together with practical solutions of ringing and genetic monitoring of released mallards.

    Same stock, different management: Quantifying the sustainability of three shrimp fisheries in the Skagerrak from a product perspective2016Inngår i: ICES Journal of Marine Science, ISSN 1054-3139, E-ISSN 1095-9289, Vol. 73, nr 7, 1806-1814 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The northern shrimp (Pandalus borealis L.) stock in the Skagerrak is shared by Sweden, Norway, and Denmark. Although the fishery is regulated by an annual agreement between the EU and Norway, there are also national regulations as well as differences in fleet composition and shrimp markets. In early 2014, the World Wildlife Fund gave all Skagerrak shrimp a red light in their seafood consumer guide, which led to an extensive debate, especially in Sweden, about the sustainability of this fishery. The aim of this study was to quantify a set of indicators that together give a broad picture of the sustainability of the three fisheries to provide an objective basis for a discussion on needed measures. The different indicators concerned environmental, economic or social aspects of sustainability and were quantified per tonne of shrimp landed by each country in 2012. The Danish fishery was most efficient in terms of environmental and economic indicators, while the Swedish fishery provided most employment per tonne of shrimp landed. Fuel use in all fisheries was high, also when compared with other shrimp fisheries. Interesting patterns emerged, with smaller vessels being more fuel efficient than larger ones in Sweden and Norway, with the opposite trend in Denmark. The study also demonstrated major data gaps and differences between the countries in how data are collected and made available. Various improvement options in the areas data collection and publication, allocation of quotas and enforcement of regulations resulted. Product-oriented studies could be useful to follow-up performance of fisheries over time and to identify how to best utilize the Skagerrak shrimp stock. This could involve evaluating novel solutions in terms of technology and management, based on current and future scenarios aiming to maximize societal benefits generated from this limited resource, at minimized environmental impacts. © 2016 International Council for the Exploration of the Sea 2016.
