Insect pollinators of crops and wild plants are under threat globally and their decline or loss
could have profound economic and environmental consequences. Here, we argue that …

Bees pollinate most of the world's wild plant species and provide economically valuable
pollination services to crops; yet knowledge of bee conservation biology lags far behind …

Pollination is a well-studied and at the same time a threatened ecosystem service. A
significant part of global crop production depends on or profits from pollination by animals …

Bees are major pollinators of Angiosperms and therefore their apparent decline is of
importance for humans and biodiversity. We synthesise results of 12 recent reviews to …

Europe harbours several endemic honeybee (Apis mellifera) subspecies. Yet the distribution
of these subspecies is nowadays also much influenced by beekee** activities. Large …

Honey bee populations have experienced serious losses in Europe and North America.
These losses highlight the potential risk to our agricultural systems that could result from loss …

Concerns about the rapid and severe declines of many bumble bee (Bombus spp.) species
in Europe, and more recently North America, have spurred research into the extent and …

Though they are relatively understudied, non-native bees are ubiquitous and have
enormous potential economic and environmental impacts. These impacts may be positive or …

Solitary bees and other wild pollinators provide an important ecosystem service which can
benefit both the agricultural economy and the sustainability of many native ecosystems …

Division of labor among workers is common in insect societies and is thought to be important
in their ecological success. In most species, division of labor is based on age (temporal …
