Bee declines driven by combined stress from parasites, pesticides, and lack of flowers
TLDR
The stresses bees are experiencing from climate change, infectious diseases, and insecticides are reviewed, with concern that the authors may be nearing a “pollination crisis” in which crop yields begin to fall. Expand
Decline and conservation of bumble bees.
TLDR
Suggested measures include tight regulation of commercial bumble bee use and targeted use of environmentally comparable schemes to enhance floristic diversity in agricultural landscapes to prevent further declines. Expand
REVIEW: An overview of the environmental risks posed by neonicotinoid insecticides
TLDR
Major knowledge gaps remain, but current use of neonicotinoids is likely to be impacting on a broad range of non-target taxa including pollinators and soil and aquatic invertebrates and hence threatens a range of ecosystem services. Expand
Bumblebees: Behaviour, Ecology, and Conservation
TLDR
This chapter discusses competition and Niche Differentiation in Bumblebee Communities, and the effects of introduced Bees on Bumblebees Abroad Effects of Introduced Bees. Expand
Effects of introduced bees on native ecosystems
TLDR
Negative impacts of exotic bees need to be carefully assessed before further introductions are carried out. Expand
Bumblebees: their behaviour and ecology.
TLDR
This book discusses social organisation and conflict in bumblebee communities, foraging economics, and the effects of introduced bees on native ecosystems. Expand
Neonicotinoid Pesticide Reduces Bumble Bee Colony Growth and Queen Production
TLDR
Given the scale of use of neonicotinoid insecticides, it is suggested that they may be having a considerable negative impact on wild bumble bee populations across the developed world. Expand
Causes of rarity in bumblebees
TLDR
Overall, Fabaceae appear to be the major pollen source for most bumblebee species, but long-tongued, late emerging species such as Bombus ruderatus, Bombus humilis and Bombus subterraneus specialize heavily in gathering pollen from Fabaceae, and this group of bumblebees species have all declined. Expand
Environmental fate and exposure; neonicotinoids and fipronil
TLDR
There is strong evidence that soils, waterways, and plants in agricultural environments and neighboring areas are contaminated with variable levels of neonicotinoids or fipronil mixtures and their metabolites, and this provides multiple routes for chronic exposure of nontarget animals. Expand
Bumblebee flight distances in relation to the forage landscape.
TLDR
To this knowledge, this is the first time that empirical data on foraging distances and forage availability, at this resolution and scale, have been collected and combined for bumblebees. Expand
