Pollination and other ecosystem services produced by mobile organisms: a conceptual framework for the effects of land-use change.

TLDR
A conceptual model for exploring how one mobile-agent-based ecosystem service (MABES), pollination, is affected by land-use change, and then generalize the model to other MABES is developed.

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…

Climate change impacts on bumblebees converge across continents

TLDR
Using long-term observations across Europe and North America over 110 years, testing for climate change–related range shifts in bumblebee species across the full extents of their latitudinal and thermal limits and movements along elevation gradients found cross-continentally consistent trends in failures to track warming through time at species’ northern range limits.

Complementary sex determination substantially increases extinction proneness of haplodiploid populations.

  • 26 July 2005
TLDR
Using stochastic modeling, it is discovered that diploid male production can initiate a rapid and previously uncharacterized extinction vortex and haplodiploids are more, rather than less, prone to extinction for genetic reasons.

Evidence for decline in eastern North American bumblebees (Hymenoptera: Apidae), with special focus on Bombus affinis Cresson

TLDR
An impoverishment of the bumblebee community in southern Ontario over the past 35 years is documents and the extent of range decline for a focal species was estimated by surveying 43 sites throughout its known native range in eastern Canada and the United States.

The potential of cleptoparasitic bees as indicator taxa for assessing bee communities

TLDR
It is proposed that functional diversity of bee communities offers a more consistent means of evaluation and suggested that cleptoparasitic bees in particular show much promise as indicator taxa.

DNA barcoding a regional bee (Hymenoptera: Apoidea) fauna and its potential for ecological studies

TLDR
Most members of this well‐known fauna of Nova Scotia, Canada were resolved with particular clarity; the average intraspecific divergence was less than 0.5%, and COI sequences from over 75% of the province's species are now in the Barcodes of Life Data System.

Social evolution and its correlates in bees of the subgenus Evylaeus (Hymenoptera; Halictidae)

TLDR
It is argued that parental manipulation has been an important component of social evolution in these bees and the lack of any relationship between polygyny and social level implies that the semisocial route to eusociality was not the one taken.
