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

Biodiversity is shrinking rapidly, and despite our efforts only a small part of it has been
assessed for extinction risk. Identifying the traits that make species vulnerable might help us …

Climate change could increase species' extinction risk as temperatures and precipitation
begin to exceed species' historically observed tolerances. Using long-term data for 66 …

Wild and managed bees are key pollinators, ensuring or enhancing the reproduction of a
large fraction of the world's wild flowering plants and the yield of∼ 85% of all cultivated …

Land-use change threatens global biodiversity and may reshape the tree of life by favoring
some lineages over others. Whether phylogenetic diversity loss compromises ecosystem …

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 …

Bees are important pollinators of wild and agricultural plants 1, 2, 3, 4, 5 and there is
increasing evidence that many bee populations decline due to a combination of habitat loss …

Microplastics (MPs) are an emerging threat to ecological conservation and biodiversity;
however, little is known of the types and possible impacts of MPs in pollinators. To examine …

Climate plays a key role in sha** population trends and determining the geographic
distribution of species because of limits in species' thermal tolerance. An evaluation of …

Invasive alien species modify pollinator biodiversity and the services they provide that
underpin ecosystem function and human well-being. Building on the Intergovernmental …
