Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:

Torgersen, Christian E.

Abstract:

This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

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....

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:

Frey, Sarah J. K.

Abstract:

Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...
