All Master's Theses
Understanding the impact of different landscape features on the movement of genes among populations can be helpful in managing wildlife populations. Our study used GIS tools to compare genetic connectivity among 13 American pika (Ochotona princeps) habitat patches across an approximately 77 square km area adjacent to Interstate 90 near Snoqualmie Pass, WA. Tissue samples were collected from 85 individuals and genotyped at six microsatellite loci to determine genetic differentiation among each pair of patches. A variety of models estimating the influence of landscape factors on gene flow were then used to find “resistance scores” between each pair …
