Proteomic Characterization of the Venom of Five Bombus (Thoracobombus) Species
Toxins, 2017 Venomous animals use venom, a complex biofluid composed of unique mixtures of proteins and peptides, to act on vital systems of the prey or predator. In bees, venom is solely used for defense against predators.

Metabolomics-based biomarker discovery for bee health monitoring : a proof of concept study concerning nutritional stress in Bombus terrestris [PDF]
, 2019 Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is critical to pollinator monitoring and may serve ...

Ecological Entomology, Volume 51, Issue 1, Page 165-176, February 2026.Forest cover significantly influences the wing shape of female Trypoxylon lactitarse. Females exhibit longer and narrower wings, linked to greater flight efficiency and dispersal. Sexual dimorphism indicates that females respond differently to ecological pressures, underscoring the role of forest cover in species persistence.

Fatty Acids from Pool Lipids as Possible Precursors of the Male Marking Pheromone in Bumblebees
Molecules, 2014 Triacylglycerols (TGs) stored in the fat bodies of bumblebee males have a species-specific composition. The striking structural similarities between TG fatty acids (FAs) and components of the male marking pheromone in certain species led to the ...

Special Issue: Food Sustainability, the Food System, and Alaskans [PDF]
, 2011 [Geography] -- The Alaska Food Policy Council: Everyone knows that food is important, but our dependence upon Outside for the stuff of life has finally begun to seem, well, just a little discomfiting to Alaska's policymakers.

Queen control of a key life-history event in a eusocial insect [PDF]
, 2013 In eusocial insects, inclusive fitness theory predicts potential queen–worker conflict over the timing of events in colony life history. Whether queens or workers control the timing of these events is poorly understood.

Life‐history traits predict the ability of British wild bees to fill their climate envelopes
Ecological Entomology, Volume 51, Issue 1, Page 31-40, February 2026.Many species of wild bees in Great Britain do not fill their entire suitable climate envelope. Life‐history traits, including habitat breadth, pollen foraging specialisation and body size influence how much of their climate envelope a species can fill Large, generalist species face fewer, or are better able to overcome, barriers to dispersal.

Bumblebee assemblages (Hymenoptera, Apidae) of ruderal habitats in the Kola Peninsula, NW Russia
Fauna Norvegica, 2015 Bumblebee assemblages of ruderal habitats were studied in the Kola Peninsula in 2012. The number of species in the assemblages varies from 7 to 11. Of cryptic species Bombus sensu stricto in the Kola Peninsula only Bombus cryptarum was registered.
