Bumblebees are ubiquitous, cold‐adapted eusocial bees found worldwide from subarctic to
tropical regions of the world. They are key pollinators in most temperate and boreal …

To fuel their activities and rear their offspring, foraging bees must obtain a sufficient quality
and quantity of nutritional resources from a diverse plant community. Pollen is the primary …

Bumble bees are a longstanding model system for studies on behaviour, ecology and
evolution, due to their well‐studied social lifestyle, invaluable role as wild and managed …

Background The shift from solitary to social behavior is one of the major evolutionary
transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution …

Potential declines in native pollinator communities and increased reliance on pollinator‐
dependent crops have raised concerns about native pollinator conservation and dispersal …

The distribution of genetic diversity within and among populations in relation to species'
geographic ranges is important to understanding processes of evolution, speciation, and …

Much of the world's terrestrial landscapes are being altered by humans in the form of
agriculture, urbanization and pastoral systems, with major implications for biodiversity …

Understanding evolutionary responses to variation in temperature and precipitation across
species ranges is of fundamental interest given ongoing climate change. The importance of …

Unraveling molecular mechanisms of adaptation to complex environments is crucial to
understanding tolerance of abiotic pressures and responses to climatic change. Epigenetic …

Phenotypic polymorphism can constitute an inherent challenge for species delimitation. This
issue is exemplified in bumble bees (Bombus), where species can exhibit high colour …
