Genome-wide analysis reveals associations between climate and regional patterns of adaptive divergence and dispersal in American pikas.

ABSTRACT: Understanding the role of adaptation in species' responses to climate change is important for evaluating the evolutionary potential of populations and informing conservation efforts. Population genomics provides a useful approach for identifying putative signatures of selection and the underlying environmental factors or biological processes that may be involved. Here, we employed a population genomic approach within a space-for-time study design to investigate the genetic basis of local adaptation and reconstruct patterns of movement across rapidly changing environments in a thermally sensitive mammal, the American pika (Ochotona princeps). Using genotypic data at 49,074 single-nucleotide polymorphisms (SNPs), we analyzed patterns of genome-wide diversity, structure, and migration along t
