New research confirms plight of bumble bees, persistence of other bees in Northeast

A new study shows that although certain bumble bees are at risk, other bee species in the northeastern United States persisted across a 140-year period despite expanding human populations and changing land use. Led by Rutgers University and based extensively on historical specimens from the American Museum of Natural History and nine other bee collections, the study informs conservation efforts aimed at protecting native bee species and the important pollinator services they provide.
