Bumble bees (Bombus) are unusually important pollinators, with approximately 260 wild
species native to all biogeographic regions except sub-Saharan Africa, Australia, and New …

Wild and managed bees are essential for global food security and the maintenance of
biodiversity. At present, the conservation of wild bees is hampered by a huge shortfall in …

Mounting evidence suggests that climate change, agricultural intensification and disease
are impacting bumblebee health and contributing to species' declines. Identifying how these …

Effective monitoring is necessary to provide robust detection of bee declines. In the United
States and worldwide, bowl traps have been increasingly used to monitor native bees and …

Declines of many bumble bee species have raised concerns because of their importance as
pollinators and potential harbingers of declines among other insect taxa. At present, bumble …

Agricultural intensification is a key suspect among putative drivers of recent insect declines,
but an explicit link between historical change in agricultural land cover and insect …

Wild bees are important pollinators in many ecosystems threatened by anthropogenic
disturbance. Urban development can reduce and degrade natural habitat for bees and other …

Evidence for global bee population declines has catalyzed a rapidly evolving area of
research that aims to identify the causal factors and to effectively assess the status of …

Wild bees form diverse communities that pollinate plants in both native and agricultural
ecosystems making them both ecologically and economically important. The growing …

Populations of bumblebees and other pollinators have declined over the past several
decades due to numerous threats, including habitat loss and degradation. However, we can …
