Aging without functional senescence in honey bee workers [PDF]
Current Biology, 2007 Senescence can be defined demographically as an age- dependent increase in mortality risk, or functionally as a decline in performance. The relationship between the two phenomena is central for understanding the biological aging process and the implications of human lifespan extension [1 ].

Forager bees (Apis mellifera) highly express immune and detoxification genes in tissues associated with nectar processing. [PDF]
, 2015 Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood.

The evolution of eusociality in allodapine bees: workers began by waiting [PDF]
Biology Letters, 2010 Understanding how sterile worker castes in social insects first evolved is one of the supreme puzzles in social evolution. Here, we show that in the bee tribe Allodapini, the earliest societies did not entail a foraging worker caste, but instead comprised females sharing a nest with supersedure of dominance.

Spatial ecology of a range-expanding bumble bee pollinator [PDF]
, 2019 Molecular methods have greatly increased our understanding of the previously cryptic spatial ecology of bumble bees (Bombus spp.), with knowledge of the spatial ecology of these bees being central to conserving their essential pollination services ...

Hemocyte-mediated phagocytosis differs between honey bee (Apis mellifera) worker castes.
PLoS ONE, 2017 Honey bees as other insects rely on the innate immune system for protection against diseases. The innate immune system includes the circulating hemocytes (immune cells) that clear pathogens from hemolymph (blood) by phagocytosis, nodulation or ...

Low-Temperature Stress during Capped Brood Stage Increases Pupal Mortality, Misorientation and Adult Mortality in Honey Bees. [PDF]
PLoS ONE, 2016 Honey bees (Apis mellifera) are key pollinators, playing a vital role in ecosystem maintenance and stability of crop yields. Recently, reduced honey bee survival has attracted intensive attention.

Queens and Workers Contribute Differently to Adaptive Evolution in Bumble Bees and Honey Bees [PDF]
Genome Biology and Evolution, 2017 Eusociality represents a major transition in evolution and is typified by cooperative brood care and reproductive division of labor between generations. In bees, this division of labor allows queens and workers to phenotypically specialize. Worker traits associated with helping are thought to be crucial to the fitness of a eusocial lineage, and recent ...

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 ...
