Secondary impacts of harvest on wild populations and ecosystems
This module will provide an overview of the effects of harvesting on wild populations and the communities in which they exist. Traditional approaches to harvesting largely assume a population exists in isolation and that harvesting acts to primarily change the size and or composition of the population. Increasingly, however, evidence suggests that failure to consider secondary effects of harvesting may lead to decreased productivity, population decline and in some cases extirpation.
Syllabus to include:
Review of compensatory harvest theory
Harvesting populations within a community
Trophic interactions and Trophic cascades
Evolutionary effects of fishing and hunting
