The western honey bee originated in Asia before adaptively radiating into Africa and Europe.
Eusociality has independently evolved multiple times in the hymenoptera, but patterns of adaptive molecular evolution underlying and elaboration eusociality remain uncertain. Here, we performed a population genomics study primitively eusocial Polistes (paper wasps), compared their to two social bees; Bombus (bumblebees), Apis (honey bees). This species triad allowed us across gradient complexity (Polistes < Apis) compare pairs that have similar (i.e. Bombus) or different life histories,...
While much of the focus sociobiology concerns identifying genomic changes that influence social behaviour, we know little about consequences behaviour on genome evolution. It has been hypothesized evolution can strength negative selection via two mechanisms. First, division labour efficiency in a caste-specific manner; indirect worker traits is theoretically expected to be weaker than direct queen traits. Second, increasing complexity lead relaxed because its effective population size. We...
The fungus that causes bat white-nose syndrome (WNS) recently leaped from eastern North America to the Pacific Coast. pathogen’s spread is associated with genetic population structure of a host ( Myotis lucifugus). To understand fine-scale neutral and immunogenetic variation among northern populations M. lucifugus, we sampled 1142 individuals across species’ range. We used genotypes at 11 microsatellite loci reveal of, directional gene flow among, predict likely future pathogen in northwest...
