Factors Influencing the Reproductive Ability of Male Bees: Current Knowledge and Further Directions

open access: yesInsects, 2021
Bumblebees and honeybees are very important pollinators and play a vital role in agricultural and natural ecosystems. The quality of their colonies is determined by the queens and the reproductive drones of mother colonies, and mated drones transmit ...

Optimizing Laboratory Rearing of a Key Pollinator, Bombus impatiens

open access: yesInsects, 2021
Bumble bees are key pollinators for wild and managed plants and serve as a model system in various research fields, largely due to their commercial availability.

The effect of the brood and the queen on early gene expression in bumble bee workers' brains

open access: yesScientific Reports, 2022
Worker reproduction in social insects is often regulated by the queen, but can be regulated by the brood and nestmates, who may use different mechanisms to induce the same outcomes in subordinates. Analysis of brain gene expression patterns in bumble bee

A review of pollinator conservation and management on infrastructure supporting rights-of-way

open access: yesJournal of Pollination Ecology, 2012
Early successional landscapes along or adjacent to infrastructure installations have been highlighted as potential pollinator conservation zones that provide environmental benefits and ameliorate some of the negative impacts of wildland conversion ...

Differential gene expression underlying the biosynthesis of Dufour's gland signals in Bombus impatiens

open access: yesCurrent Research in Insect Science, 2023
Pheromones regulating social behavior are one of the most explored phenomena in social insects. However, compound identity, biosynthesis and their genetic basis are known in only a handful of species.

Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover [PDF]

open access: yes, 2018
Understanding spatial variation in the structure and stability of plant-pollinator networks, and their relationship with anthropogenic drivers, is key to maintaining pollination services and mitigating declines.

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

open access: yes, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Dufour’s gland analysis reveals caste and physiology specific signals in Bombus impatiens

open access: yesScientific Reports, 2021
Reproductive division of labor in insect societies is regulated through multiple concurrent mechanisms, primarily chemical and behavioral. Here, we examined if the Dufour’s gland secretion in the primitively eusocial bumble bee Bombus impatiens signals ...
