Ecological And Genetic Connectivity Of Shrews (Sorex Spp.) Across Interstate-90 In The Washington Cascade Range, Jordan Ryckman

All Master's Theses

Roads negatively affect wildlife by degrading and fragmenting habitat. The I-90 Snoqualmie Pass East project was established to improve traffic safety for both humans and wildlife. Here, the Washington State Department of Transportation is constructing wildlife crossing structures to increase ecosystem connectivity as part of this project. The goal of my study was to investigate shrews – very small mammals with presumably low mobility and dispersal capacity – at sites on the eastern slopes of the Cascade Range where wildlife crossing structures will be built in the future. My main objectives were to verify shrew species composition, assess population genetic …
