Abstract
In the Anthropocene, cities have introduced challenges not previously seen in the evolutionary history of bees, particularly through changes to landscape structure with impervious surfaces and scattered green spaces. Our study examines the spatial behavior of Bombus impatiens (Common Eastern Bumblebee) indirectly through a genetic mark recapture study. DNA samples were obtained through non-lethal sampling in 5 focal areas of the greater St. Louis area in Summer 2023. Sample sites within each focal area were obtained through outreach with the St. Louis Community and included private residences, schools, golf courses, cemeteries, community gardens, parks, and restored prairies. Samples underwent whole genome sequencing to compare areas across the city, in addition to how landscape variables influenced aspects of gene flow. Results of our study will reveal if portions of St. Louis act as barriers to movement and if Bombus impatiens is experiencing population structuring. This study informs if bumblebee foraging is influenced by landscape variables, or more broadly, how human alterations to landscapes influence foraging behavior.
