Allele specific expression and methylation in the bumblebee, Bombus terrestris

PeerJ, 2015
ABSTRACT The social hymenoptera are emerging as models for epigenetics. DNA methylation, the addition of a methyl group, is a common epigenetic marker. In mammals and flowering plants methylation affects allele specific expression.

How landscape, pollen intake and pollen quality affect colony growth in Bombus terrestris

, 2016
Context: Abundance and diversity of bumblebees have been declining over the past decades. To successfully conserve bumblebee populations, we need to understand how landscape characteristics affect the quantity and quality of floral resources collected by

Status and monitoring of the buff-tailed bumblebee Bombus terrestris Linnaeus (Hymenoptera: Apidae) in Southern Finland [PDF]

, 2014
Bombus terrestris can cause pollination disturbance in native plants and compete with native bumblebees and other pollinators. The accompanying non-native parasites may also threaten native bees. We report new observations of the commercially used Bombus

Analysis of a normalised expressed sequence tag (EST) library from a key pollinator, the bumblebee Bombus terrestris

BMC Genomics, 2010
Background The bumblebee, Bombus terrestris (Order Hymenoptera), is of widespread importance. This species is extensively used for commercial pollination in Europe, and along with other Bombus spp.

Colour pattern and DNA-barcoding reveal a wide distribution of the insular endemic bumble bee Bombus xanthopus in the Tuscan Archipelago

The European Zoological Journal
Insular ecosystems, due to their isolation from the mainland and limited areas, are often endemism hotspots. However, the same factors that drive high endemicity also make islands vulnerable to anthropogenic pressure and thus to biodiversity loss.

Buzzing benefits: How multi-species pollination boosts strawberry yield, quality, and nutritional value

Journal of Pollination Ecology
A diverse assemblage of insect visitors can provide functional complementarity within plant pollination due to differences in characteristics such as their physical traits, visitation rate and foraging time of day or year.

Bumblebees gain fitness through learning [PDF]

, 2007
Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning

Colony growth of the bumblebee, Bombus terrestris, in improved and conventional agricultural and suburban habitats

, 2002
Many bumblebee species are declining at a rapid rate in the United Kingdom and elsewhere. This is commonly attributed to the decline in floral resources that has resulted from an intensification in farming practices. Here we assess growth of nests of the
