Research in Alaska
I am presently in the process of wrapping up research in Alaska that covered two broad themes. We first examined how fish were distributed in lake systems and the primary landscape filters affecting the composition of fish in these lakes. We linked the distribution of fish both to the nesting preferences of fish predators (yellow-billed loons) and the ecosystem consequences of fish presence on lake food webs. The second theme brought a unique perspective to fisheries research in Alaska, leaning away from understanding core habitat needs and population dynamics of core populations, but rather improving our understanding of evolutionary processes that lead to the use of non-core or peripheral habitats by juvenile or incubating salmon. Our interest was in how rare features of the landscape and peripheral areas, such as estuaries, could account for overall population persistence in a changing environment.
