Welcome to the Armstrong Lab  website. My research group explores how the physical features of watersheds influence consumer energy budgets, population dynamics, and ecosystem services. We research this topic because it is both important and fascinating. Watershed habitat supports fish and wildlife that in turn feed people, drive regional economies, and provide a range of cultural services. To understand how fish and wildlife interact with the diverse physical template of watersheds requires an integration of animal behavior, physiology, and landscape ecology. In our research we work at the nexus of these fields to gain novel insights into how animals interact with their environment and how human activities alter this fundamental relationship.


Much of my past and ongoing research has focused on coastal watersheds of Alaska, in regions including Bristol Bay, Kodiak Island, and the Copper River Delta. I recently joined the faculty at the Oregon State University Department of Fisheries and Wildlife and I am expanding my research portfolio to include local projects in the Pacific Northwest. My lab has begun work on the movement ecology of redband rainbow trout in Upper Klamath Lake , the effects of drought-induced habitat fragmentation on ESA-listed coho salmon in the Lower Columbia River, and the use of coldwater refugia by coastal cutthroat trout on the Willamette River.
