Parasite Prevalence May Drive the Biotic Impoverishment of New England (USA) Bumble Bee Communities.

Numerous studies have reported a diversity of stressors that may explain continental-scale declines in populations of native pollinators, particularly those in the genus . However, there has been little focus on the identification of the local-scale dynamics that may structure currently impoverished communities. For example, the historically diverse coastal-zone communities of New England (USA) now comprise only a few species and are primarily dominated by a single species,  .
