All Master's Theses
Single-nucleotide polymorphisms (SNPs) were used to assess the genetic connectivity of western toad (Anaxyrus boreas) breeding populations along Interstate-90 near Snoqualmie Pass, WA. Sites north and south of the freeway were sampled during the breeding season of 2019. SNP loci were subsequently generated using the proprietary DArTseqTM (Canberra, ACT, Australia) method. A total of 15,468 SNPs were used to calculate pairwise FST values and three distinct breeding populations were identified, two north and one south of I-90. All pairwise FST values between these sites were low (0.02) but significantly different from 0. The lowest pairwise …
