#University of Hawaiʻi bumble bee

A rare North American bumble bee may have been on a path toward extinction long before modern human impacts, suggesting that its long-term genetic vulnerability made it especially fragile and less able to cope with both past and current environmental stresses. The findings of the new study were published in the Proceedings of the National Academy of Sciences on Oct. 20, and co-authored by a University of Hawaiʻi at Mānoa researcher.
