Reduced genetic diversity associated with the northern expansion of an amphibian species with high habitat-specialization, Ascaphus truei, resolved using two types of genetic markers

Consists of four datasets and one README file. One dataset (ECE-2021-04-00657-R2-microsat-MOSHER.csv) is the microsatellite dataset and is based on the format of a STRUCTURE file. Two data sets represent the genotype-by-sequencing work and are based on the format of a STRUCTURE file. One (ECE-2021-04-00657-R2-gbs-tripcomp-MOSHER.csv) includes samples from the British Columbia, CA, geographic regions and triplicate and duplicate samples. The other (ECE-2021-04-00657-R2-gbs-notrips-MOSHER.csv) includes all geographic regions and has the replicates removed. Missing data is coded with '-9'. The final dataset (ECE-2021-04-00657-R2-gbs-mtDNA-MOSHER.csv) is the mtDNA data, and is based on the format of a NEXUS file. Missing data is coded with '?'.
