Watershed-level patterns among stream amphibians in the Blue River watershed, West-Central Cascades of Oregon

Creator:

Hunter, Matthew G.

Abstract:

Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...

Population genetics of ranid frogs : investigating effective population size and gene flow

Creator:

Phillipsen, Ivan C.

Abstract:

This dissertation focuses on the evolutionary forces of genetic drift and gene flow in frog populations. The balance of these two forces and the force of mutation largely determine the amount of neutral genetic variation within populations as well as the degree of genetic similarity among populations. The stochastic evolutionary...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:

Bury, Gwendolynn W.

Abstract:

Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....
