| 英文摘要 | Quaternary climate oscillations have profoundly influenced current species distributions. For many montane species, these fluctuations were a prominent driver in species range shifts, often resulting in intraspecific diversification, as has been the case for American pikas (Ochotona princeps). Range shifts and population declines in this thermally -sensitive lagomorph have been linked to historical and contemporary environmental changes across its western North American range, with previous research reconstructing five mitochondrial DNA lineages. Here, we paired genome-wide data (25,244 SNPs) with range -wide sampling to re-examine the number and distribution of intra-specific lineages, and investigate patterns of within- and among -lineage divergence and diversity. Our results provide genomic evidence of O. princeps monophyly, reconstructing six distinct lineages that underwent multiple rounds of divergence (0.809-2.81 mya), including a new Central Rocky Mountain lineage. We further found evidence for population differentiation across multiple spatial scales, and reconstructed levels of standing variation comparable to those found in other small mammals. Overall, our findings demonstrate the influence of past glacial cycles on O. princeps lineage diversification, suggest that current subspecific taxonomy may need to be revisited, and provide an important framework for investigations of American pika adaptive potential in the face of anthropogenic climate change. |
