Genetic diversity of the honeybee in Africa: microsatellite and mitochondrial data
The use of both nuclear and mitochondrial DNA often display discordant patterns of differentiation in the honeybee is preferable when assessing the phylogeography of Apis mellifera and to determine the taxonomic status of the subspecies. Expand
Ancestral Monogamy Shows Kin Selection Is Key to the Evolution of Eusociality
It is found that mating with a single male, which maximizes relatedness, is ancestral for all eight independent eusocial lineages that are investigated, and monogamy was critical in the evolution of eussociality, strongly supporting the prediction of inclusive fitness theory. Expand

American beekeepers reported unusually high rates of colony loss in early 2007 as bees broke from their overwintering clusters. Researchers are struggling to explain what's behind this mysteriousExpand
Honey Bee Nest Thermoregulation: Diversity Promotes Stability
It is shown that brood nest temperatures in genetically diverse colonies ( i.e., those sired by several males) tend to be more stable than in genetically uniform ones (i.e, those sire by one male). Expand
Nest thermoregulation in social insects
Abstract Most social insect species are able to regulate the temperature within their nests. In this review, we examine the variety of mechanisms that social insect species have evolved to regulateExpand
The effects of rearing temperature on developmental stability and learning and memory in the honey bee, Apis mellifera
It is shown that short-term learning and memory abilities of adult workers are affected by the temperature they experienced during pupal development, and that the most important consequence of abnormal rearing temperatures are subtle neural deficiencies affecting short- term memory rather than physical abnormalities.

Mitochondrial DNA variation in Moroccan and Spanish honey bee populations
The mitochondrial DNAs of 192 Moroccan and 173 Spanish honey bee colonies were characterized by a rapid test involving the restriction by DraI of a PCR‐fragment of the COI‐COII region, showing that Morocco was most probably colonized by two sublineages and that the contact zone between them extends along both sides of the Atlas range.

Evolution of multiple mating in the genus Apis
Genetic variance hypotheses which posit that both queen and colony fitness are increased by an increase in the intracolonial genetic diversity that accrues from multiple mating are probably insufficient to explain extreme levels of polyandry observed in the genus Apis. Expand
Multiple paternity or multiple queens: two routes to greater intracolonial genetic diversity in the eusocial Hymenoptera
It is suggested that fitness benefits resulting from increased intracolonial genetic diversity have played an important role in the evolution of polyandry, and possibly polygyny, in social insects. Expand
Genetic diversity promotes homeostasis in insect colonies.
It is argued here that a contributing factor towards the evolution of polyandry is that the resulting genetic diversity within colonies provides them with a system of genetically based task specialization, enabling them to respond resiliently to environmental perturbation. Expand
