英文摘要	Maintenance of phenotypic and genotypic diversity within and across species and populations is critical for their capacity to survive and adapt to changing environments. Climate change potentially puts cryptic diversity and populations at increased risk, highlighting the importance of quantifying and understanding this diversity before it is lost. This study focuses on Bombus lapponicus sylvicola, a bumble bee species that has undergone recent taxonomic additions and revisions. We tested the null hypotheses that B. l. sylvicola over a 40,000 km2 geographic range and climatic gradient in the Canadian Rocky Mountains represented a single genetic population. Furthermore, we evaluated predictions for mechanisms behind genomic divergence among groups under this framework. We sampled bumble bees from 69 sites and used DNA from two different species (131 B. l. sylvicola and 435 individuals of the closely related B. melanopygus as an outgroup) to characterize 20,000 SNPs and measure relatedness and gene flow. We collected phenotypic data on color patterns and mapped population distribution based on environmental variables. We found evidence of two phenotypically and genetically distinct parapatric populations of B. l. sylvicola that appear to have diverged under conditions of gene flow and differential recombination. Our models suggest that these populations occupy distinct climatic regions, with a newly described cryptic population found in locations reaching a lower minimum temperature. This research presents evidence for the role of adaptative evolution in response to different climate conditions.
