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 …

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 …

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 …

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

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

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

Inclusive fitness theory predicts that in colonies of social Hymenoptera headed by a multiple‐
mated queen, workers should benefit from policing eggs laid by other workers. Foster & …

Artificial selection in closed populations can fix or differentiate alternative alleles of loci
associated with selected traits. Two closed chicken populations, A and B, originating from …
