The hexagonal cells built by honey bees and social wasps are an example of adaptive
architecture; hexagons minimize material use, while maximizing storage space and …

The objective of this study was to determine the effect of age at photostimulation on sexual
maturity and performance of layer breeders. A total of 192 fourteen-wk-old White Leghorn …

Females of many species are polyandrous. However, polyandry can give rise to conflict
among individuals within families. We examined the level of polyandry and paternity skew in …

Within any one habitat, the relative fitness of organisms in a population can vary
substantially. Social insects like the common wasp are among the most successful invasive …

Social insects rank among the most invasive of terrestrial species. The success of invasive
social insects stems, in part, from the flexibility derived from their social behaviors. We used …

Organisms face the fundamental ecological question of when to switch resources from
growth to reproduction or allocate resources between the two. Social wasps, including …

Despite the mitochondrion's long‐recognized role in energy production, mitochondrial DNA
(mtDNA) variation commonly found in natural populations was assumed to be effectively …

Highly social species are successful because they cooperate in obligately integrated
societies. We examined temporal genetic variation in the eusocial wasp Vespula …

The partitioning of resources between male and female offspring is a fundamental aspect of
the reproductive biology of animals. Sex allocation can be adjusted by controlling offspring …

Insects have evolved remarkably complex social systems. Social wasps are particularly
noteworthy because they display gradations in social behaviors. Here, we sequence the …
