Adult Rainbow Trout Habitat Selection In The Henry’S Fork Of The Snake River, Idaho, Zachary Kuzniar

Masters Theses

Determining habitat selection for an organism across a geographic distribution is a primary challenge in modern behavioral ecology. Quantifying habitat use becomes increasingly difficult for species that exhibit complex life histories and complementary habitat requirements. Rainbow trout are an archetypal example due to their tendency to form local populations across a diversity of environments. The Henry’s Fork of the Snake River provides an opportunity to utilize microhabitat selection models to quantify stream features that may drive adult rainbow trout behavior at the local scale. In particular, within an 8.5 km, low gradient, groundwater-dominated reach that exhibits a general lack of …
