Abstract

The new International Research School for Applied Ecology will focus on research that is relevant to natural resource management. In this presentation I will discuss how ecological research has informed management of salmon and trout, and ways in which I hope it will continue to do so. Salmonids show great plasticity in life history traits such as age and growth, and tremendous intra-specific diversity. This diversity is of great practical value because salmonids are highly-prized commercial, sport, and subsistence fish. Due largely to human activities such as fishing, resource extraction, and development, many native salmonid populations have declined, and much diversity has already been lost. Conservation of the remaining salmonid biodiversity will require enlightened management, informed by sound ecological science. Because salmonids home to their natal streams to spawn, populations tend to become reproductively isolated, leading to adaptations to local environmental conditions. I give examples of local adaptation in salmonids, and discuss why this mandates the need for life history-based management informed by ecological research. The principles I discuss probably apply more or less to other aquatic and terrestrial taxa as well, and they should be of use in demonstrating the important link between ecology and conservation
