Ecological and life-history traits predict bee species responses to environmental disturbances
- Neal M. Williams, E. Crone, T'ai H. Roulston, R. Minckley, L. Packer, S. Potts
- Biology
- 1 October 2010
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 managers… Expand
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 organisms… Expand
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 species… Expand
Complementary sex determination substantially increases extinction proneness of haplodiploid populations.
The role of genetic factors in extinction is firmly established for diploid organisms, but haplodiploids have been considered immune to genetic load impacts because deleterious alleles are readily… Expand

- 10 July 2015
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
- Sheila R. Colla, L. Packer

- Biodiversity and Conservation
- 8 February 2008
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 not… Expand
The potential of cleptoparasitic bees as indicator taxa for assessing bee communities

- 21 February 2013
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 bee… Expand
DNA barcoding a regional bee (Hymenoptera: Apoidea) fauna and its potential for ecological studies
- C. S. Sheffield, P. Hebert, P. Kevan, L. Packer
- Biology, Medicine
- Molecular ecology resources
- 21 April 2009
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 as… Expand
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 explains… Expand
