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.

Diversity of Bacterial Communities Associated with Solitary Bee Osmia excavata Alfken (Hymenoptera: Megachilidae)

open access: yesApplied Sciences, 2023
Insect-associated microorganisms play important roles in the health and development of insects. This study aimed to investigate the similarities and differences in bacterial community structure and composition between the larval gut of Osmia excavata ...

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.

The macroeconomic cost of catastrophic pollinator declines [PDF]

open access: yes, 2016
We develop a computable general equilibrium (CGE) approach to assess the macroeconomic impacts of productivity shocks due to catastrophic losses of pollination ecosystem services at global and regional scales.

Developing European conservation and mitigation tools for pollination services: approaches of the STEP (Status and Trends of European Pollinators) project [PDF]

open access: yes, 2011
Pollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying ...

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 ...

Investigations into stability in the fig/ fig-wasp mutualism [PDF]

open access: yes, 2010
Fig trees (Ficus, Moraceae) and their pollinating wasps (Chalcidoidea, Agaonidae) are involved in an obligate mutualism where each partner relies on the other in order to reproduce: the pollinating fig wasps are a fig tree’s only pollen disperser ...

Topical Application of Synthetic Hormones Terminated Reproductive Diapause of a Univoltine Weed Biological Control Agent

open access: yesInsects, 2021
Classical biological control is an important method for controlling invasive alien weeds. Univoltine insects can be highly effective biological control agents of annual weeds because they are well synchronized with their host plant.
