Plants may benefit from limiting the community of generalist floral visitors if the species that
remain are more effective pollinators and less effective pollenivores. Plants can reduce …

Declines in wild and managed bee species richness and abundances have been observed
throughout Europe and North America in recent decades. These declines have led to …

Although models of colony organization in social insects often rely on the assumption that
within-group variation increases group performance, empirical support for this is mostly …

Body size is arguably one of the most important traits influencing the physiology and ecology
of animals. Shifts in animal body size have been observed in response to climate change …

Size‐number trade‐offs in reproduction are commonly observed in nature. Bumblebee
(Bombus spp.) colonies produce workers that vary considerably in size. This variation …

The systemic neonicotinoid insecticides are considered as one of the key culprits
contributing to ongoing declines in pollinator health and abundance. Bumblebees are …

A striking feature of advanced insect societies is the existence of workers that forgo
reproduction. Two broad types of workers exist in eusocial bees: nurses who care for their …
