Climbing the social ladder: the molecular evolution of sociality.
Genomic tools are allowing us to dissect the roles of genes and genetic architecture in social evolution, and eusocial insects are excellent models. Numerous hypotheses for molecular evolution of… Expand

Microbial Gut Diversity of Africanized and European Honey Bee Larval Instars
The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming… Expand

A Mid-Cretaceous Origin of Sociality in Xylocopine Bees with Only Two Origins of True Worker Castes Indicates Severe Barriers to Eusociality
The origin of sterile worker castes, resulting in eusociality, represents one of the major evolutionary transitions in the history of life. Understanding how eusociality has evolved is therefore an… Expand

The effect of maternal care on gene expression and DNA methylation in a subsocial bee
Developmental plasticity describes the influence of environmental factors on phenotypic variation. An important mediator of developmental plasticity in many animals is parental care. Here, we examine… Expand

Morphological and molecular delineation of a new species in the Ceratina dupla species-group (Hymenoptera: Apidae: Xylocopinae) of eastern North America
DNA barcoding is used to verify characters to morphologically differentiate genetically distinct species of eastern North American small carpenter bees, Ceratina. Here we reveal that the common… Expand

Molecular phylogeny of the small carpenter bees (Hymenoptera: Apidae: Ceratinini) indicates early and rapid global dispersal.
The small carpenter bees (tribe Ceratinini, family Apidae) are recorded from all continents except Antarctica. The Ceratinini have a near-global distribution which contrasts strongly with their… Expand

Decline of bumble bees in northeastern North America, with special focus on Bombus terricola
Abstract Concerns about the rapid and severe declines of many bumble bee (Bombus spp.) species in Europe, and more recently North America, have spurred research into the extent and possible causes… Expand

Reproductive aggression and nestmate recognition in a subsocial bee
In social contexts, the ability to recognize and discriminate among individuals is advantageous, because it allows individuals to adjust their behaviour so as to enhance both individual and group… Expand

Social polymorphism in the Australian small carpenter bee, Ceratina (Neoceratina) australensis
The bee tribe Ceratinini provides important insights into the early stages of sociality. Many arthropods exhibit behaviours precursory to social life, including adult longevity, parental care, nest… Expand

At the brink of eusociality: transcriptomic correlates of worker behaviour in a small carpenter bee
BackgroundThere is great interest in understanding the genomic underpinnings of social evolution, in particular, the evolution of eusociality (caste-containing societies with non-reproductives that… Expand
