Molecular Ecology, EarlyView.ABSTRACT Bumble bee (Bombus Latreille) populations of certain species have declined precipitously in North America over several decades. Hypotheses for declines include exposure to the pathogen Nosema bombi and neonicotinoid pesticides. Importantly, populations of some bumble bee species remain stable despite their presumed exposure to these same ...

Strong Bottlenecks Constrain Adaptive Coevolution in a Host–Parasite Metapopulation
Molecular Ecology, EarlyView.ABSTRACT Although parasites are well‐known for adaptively evolving in order to exploit their hosts, they may experience strong genetic drift during transmission bottlenecks when infecting a new host. Host population structure and host population bottlenecks can also lead to genetic drift effects in parasite populations, constraining their adaptive ...
