Ecological and life-history traits predict bee species responses to environmental disturbances
Abstract The ability to predict the responses of ecological communities and individual species to human-induced environmental change remains a key issue for ecologists and conservation managersExpand

Pollination and other ecosystem services produced by mobile organisms: a conceptual framework for the effects of land-use change.
Many ecosystem services are delivered by organisms that depend on habitats that are segregated spatially or temporally from the location where services are provided. Management of mobile organismsExpand

Habitat heterogeneity as a determinant of mammal species richness in high-energy regions
A fundamental problem in ecological research is to explain large-scale gradients in species richness1,2. Although many causative agents for this phenomenon have been suggested, the speciesExpand

Climate change impacts on bumblebees converge across continents
Bucking the trend Responses to climate change have been observed across many species. There is a general trend for species to shift their ranges poleward or up in elevation. Not all species, however,Expand

Evidence for decline in eastern North American bumblebees (Hymenoptera: Apidae), with special focus on Bombus affinis Cresson
Bumblebees (Bombus spp.) have been declining rapidly in many temperate regions of the Old World. Despite their ecological and economic importance as pollinators, North American bumblebees have notExpand

The potential of cleptoparasitic bees as indicator taxa for assessing bee communities
Many factors affect bee diversity and abundance, and knowledge of these is crucial for maintaining healthy bee communities. However, there are few means to fully evaluate the status of beeExpand

DNA barcoding a regional bee (Hymenoptera: Apoidea) fauna and its potential for ecological studies
DNA barcoding has been evaluated for many animal taxa and is now advocated as a reliable and rapid means for species‐level identification. The coming‐to‐light of this identification tool is timely asExpand

Social evolution and its correlates in bees of the subgenus Evylaeus (Hymenoptera; Halictidae)
SummaryEleven behavioural characteristics of eight species of the subgenus Evylaeus were analysed using principal components analysis. The first component axis represents social level and explainsExpand
