Landscape heterogeneity drives population structure in four western bumble bee species

Bumble bees are critical pollinators in wild, agricultural, and urban ecosystems—providing the necessary ecological services for food and crop production. In western North America, mountain ranges have high bumble bee species richness. However, as climate change increases temperatures and restricts montane populations to higher elevational spaces, their ability to disperse and maintain genetic diversity decreases. This genetic isolation could lead to the extirpation of local pollinator communities and an overall loss of pollinators. We analyzed the genetic diversity of four broadly sympatric species of bumble bees across the Rocky and Cascade Mountains of western North America to assess habitat isolation's impact on population genetic structure. We expected species restricted to higher elevation habitats to display higher population structure and less genetic diversity across the landscape. We sampled approximately 150 bees per species from seven to eight sites across each species' rang..., , , # Data From: Landscape heterogeneity drives population structure in four western bumble bee species

## Description of the data and file structure

Each study species is represented in its own tab

Rows represent individual bee specimen allele sizes in base pairs

Blank cells represent \"missing data\"

Population =  site at which that bee was collected

Name = specimen ID

Remaining column names represent microsatellite loci with two columns per loci
