Non-lethal sampling of honey bee, Apis mellifera, DNA using wing tips
TLDR
Wing tip DNA sampling will permit a variety of novel research approaches, including genotyping of queens at emergence in breeding programs where certain patrilines or genotypes are preferred, and genotypes of workers and queens which must behave normally following sampling.
Quantifying honey bee mating range and isolation in semi-isolated valleys by DNA microsatellite paternity analysis
TLDR
The large majority of observed mating distances fell within the range of Hope Valley, making this site a suitable location for the long term conservation of a breeding population of black bees.
Anarchy in the UK: Detailed genetic analysis of worker reproduction in a naturally occurring British anarchistic honeybee, Apis mellifera, colony using DNA microsatellites
TLDR
A first detailed genetic analysis of a British anarchistic colony is reported, which suggests that workers do not move any queen‐laid eggs between the part of the colony where the queen is present to the area above the queen excluder which the queen cannot enter.
Reed warblers guard against cuckoos and cuckoldry
TLDR
It is concluded that male reed warblers do increase nest guarding in response to cuckoos, but only after their females have begun egg laying, when there are less likely to be costs in lost paternity.
Learning and discrimination of individual cuticular hydrocarbons by honeybees (Apis mellifera).
TLDR
This work uses the proboscis extension response (PER) conditioning paradigm to determine how well honeybees learn long-chain linear alkanes and (Z)-alkenes present on the cuticle of worker bees, and also how well they can discriminate between them.
NONTRANSITIVITY OF PATERNITY IN A BIRD
TLDR
Control for male‐mediated effects is controlled through the artificial insemination of known numbers of sperm in the domestic fowl to reveal that male reproductive success is nontransitive across females.
Reassessing the role of the honeybee (Apis mellifera) Dufour's gland in egg marking
TLDR
The results indicate that esters or hydrocarbons probably do not function as the signal by which eggs can be discriminated, and queens Dufour's gland secretion may allow worker honeybees to discriminate between queen-laid and worker-l laid eggs.
From speciation to introgressive hybridization: the phylogeographic structure of an island subspecies of termite, Reticulitermes lucifugus corsicus
TLDR
This study provides an unusual picture of genetic interaction between termite populations in the Tyrrhenian area and suggests that more attention should be paid to the role of introgression and human impact on the recent evolution of European termites.
