Scientists discover genetically isolated populations and population-level inbreeding in a range-wide genetic analysis of the endangered rusty patched bumble bee
Range-wide genetic analysis of the endangered rusty patched bumble bee shows surprising levels of inbreeding within populations and genetic divergence between populations. Using a genetic mark-recapture technique, scientists also found lower site-level colony abundance than previously reported.
Over the last three decades, the rusty patched bumble bee has disappeared from almost 90% of its former range. In 2017, it was federally listed as endangered under the U.S. Endangered Species Act. The genetic information generated through this study can inform managers in their conservation and restoration efforts of this endangered species.
