The conservation of bumble bees [PDF]
Bee World, 2003 The approximately 250 known species of bumble bee (genus Bombus) are found predominantly in temperate regions of the northern hemisphere. This region also contains much of the world's human population and the most intensive agricultural regions. Probably as a result of this, many bumble bees appear to be undergoing dramatic declines in range.

Olfactory coding in the antennal lobe of the bumble bee Bombus terrestris
Scientific Reports, 2021 Sociality is classified as one of the major transitions in evolution, with the largest number of eusocial species found in the insect order Hymenoptera, including the Apini (honey bees) and the Bombini (bumble bees).

Laboratory studies examining aspects of scent marking, traplining and remote detection of reward in the foraging bumblebee. [PDF]
, 2007 PhDEnergy from food is essential for the survival of all animals. For decades, bumblebees have been used as model organisms for studying animal foraging strategies.

The Potential Influence of Bumble Bee Visitation on Foraging Behaviors and Assemblages of Honey Bees on Squash Flowers in Highland Agricultural Ecosystems. [PDF]
PLoS ONE, 2016 Bee species interactions can benefit plant pollination through synergistic effects and complementary effects, or can be of detriment to plant pollination through competition effects by reducing visitation by effective pollinators.

Decline and Conservation of Bumble Bees [PDF]
Annual Review of Entomology, 2008 Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely ...

Journal of Pollination Ecology, 2018 Honey bees are being scrutinized for their potential impact upon wild bees. In lowland heath mosaics, a simple but resource rich habitat for pollinators, there is a higher probability of niche overlap for bumble bees and honey bees due to the requirement
