Genetic structure and migratory connectivity of aerial insectivores

Funding period: 2024-2028
Lead: Elsie Krebs
Total GRDI funding: $65,543

This research continues investigations on population genetics of avian aerial insectivores (e.g. swallows, flycatchers) on the North American breeding grounds to determine genetic variation across landscapes and assess migratory connectivity between their Latin America non-breeding grounds. We will augment previous genetic assays with whole genome sequencing, which provides higher resolution than other methods. Using genomics and isotopes to link aerial insectivore populations across their annual cycles (i.e. between breeding, stopover, and wintering sites), our research can help identify potential impacts of stressors across broader geographic and temporal scales and contribute to more effective conservation approaches for aerial insectivores.
