TL;DR: The draft genome sequence of a particularly widespread and well-studied species, the invasive Argentine ant, is reported, which was accomplished using a combination of 454 and Illumina sequencing and community-based funding rather than federal grant support.

TL;DR: Gene networks involved in generating key differences between the queen and worker castes show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor.
Journal ArticleDOI

TL;DR: Following recent reports of genome sequences from other insects that engage in symbioses with beneficial microbes, the A. cephalotes genome provides new insights into the symbiotic lifestyle of this ant and advances the understanding of host–microbe symbioss.
Journal ArticleDOI
Division of labor in honeybees: form, function, and proximate mechanisms
TL;DR: Honeybees exhibit two patterns of organization of work, in the spring and summer, division of labor is used to maximize growth rate and resource accumulation, while during the winter, worker survivorship through the poor season is paramount, and bees become generalists.
Journal ArticleDOI
Phylogenomics Resolves Evolutionary Relationships among Ants, Bees, and Wasps
TL;DR: This phylogeny provides a new framework for exploring the evolution of nesting, feeding, and social behavior within the stinging Hymenoptera, and is robust to multiple methods of phylogenetic inference.
