Previous studies have shown that natural honeybee and bumble bee colonies are hosts of the small hive beetle (SHB) Aethina tumida, a pest of honeybee colonies in various regions of the world. Recent studies also reported the presence of SHBs in colonies of certain...

Winter mortality is a major factor regulating population size of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Glycerol is the major cryoprotectant in this freeze intolerant insect. We report findings from a gene expression...

Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical transformations...

Chimpanzees have the largest relative brain size, greatest reproductive output, and longest lifespan of any non-human ape; they also have the highest level of physical activity in the wild, as measured by daily walking and climbing distances. In this study, we...
