Factors influencing population density of stream-living Redband Trout in southeast Oregon, USA

Creator:

Thorson, Justin M.

Abstract:

Fisheries managers often use models of population density to evaluate the status of stream-living fishes, but many of these models have low predictive performance for abundance and density. These models could incorporate several factors that can limit population density, particularly the effect of body size, envisioned by the theory of...

AN ABSTRACT OF THE THESIS OF Justin M. Thorson for the
Assessing the Effects of Contemporary Forest Harvest on Headwater Stream Food Webs in the Oregon Coast Range

Creator:

Mowlds, Emilee A.

Abstract:

Food webs are fundamental in ecology, as they offer a way to better understand the interrelatedness, connectivity, and complexity within a given ecosystem. The use of network analysis to model food webs can provide insights about the importance of physical templates on the organization of biological systems in streams using...

Seasonal Movement of Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) in Headwater Streams in Oregon

Creator:

Linkem, Christina N.

Abstract:

Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...
