The honeybee is the primary managed species worldwide for both crop pollination and
honey production. Owing to beekeeping activity, its high relative abundance potentially …

During the past decades, managed honeybee stocks have increased globally. Managed
honeybees are particularly used within mass-flowering crops and often spill over to adjacent …

Most plant–pollinator mutualisms are generalized. As such, they are susceptible to
perturbation by abundant, generalist, non-native pollinators such as the western honey bee …

Abstract The European honeybee Apis mellifera is a highly successful, abundant species
and has been introduced into habitats across the globe. As a supergeneralist species, the …

The western honey bee (Apis mellifera) is the most frequent floral visitor of crops worldwide,
but quantitative knowledge of its role as a pollinator outside of managed habitats is largely …

Introduced species can have cascading effects on ecological communities, but indirect
effects of species introductions are rarely the focus of ecological studies. For example …

Eusocial bees are likely to be ecologically important competitors for floral resources,
although competitive effects can be difficult to quantify in wild pollinator communities. To …

In diverse pollinator communities, interspecific interactions may modify the behaviour and
increase the pollination effectiveness of individual species. Because agricultural production …

Highlights•Despite growing awareness, pollinators still face mounting threats.•Honey bees
are the most important but least imperilled crop pollinator.•Honey bee popularity can be …

Niche complementarity is a commonly invoked mechanism underlying the positive
relationship between biodiversity and ecosystem functioning, but little empirical evidence …
