Simple Summary Insects, such as wasps, ants, and bees, can live in highly structured
societies characterized by a complex organization. The functioning of these societies is …

Senescence, the decline in physiological and behavioral function with increasing age, has
been the focus of significant theoretical and empirical research in a broad array of animal …

Background Adaptive manipulation of animal behavior by parasites functions to increase
parasite transmission through changes in host behavior. These changes can range from …

Ants can display modified behaviors that represent the extended phenotypes of genes
expressed by parasites that infect them. In such cases, the modifications benefit the parasite …

Complex social structure in eusocial insects can involve worker morphological and
behavioural differentiation. Neuroanatomical variation may underscore worker division of …

Colonies of the red harvester ant (Pogonomyrmex barbatus) differ in how they regulate
collective foraging activity in response to changes in humidity. We used transcriptomic …

How individual organisms whose behavior is potentially driven by selfish interests cooperate
to form a society is a central question in evolutionary biology. Worker reproduction and its …

Once established in new areas, introduced species may exhibit changes in their biology due
to phenotypic plasticity, novel selection pressures and genetic drift. Moreover, the …

Conventional definitions of drug addiction are focused on characterizing the
neurophysiological and behavioral responses of mammals. Although mammalian models …

The red imported fire ant, Solenopsis invicta Buren, is a dangerous invasive pest in the
