What to protect?—Systematics and the agony of choice
A comprehensive phylogeny of the bumble bees (Bombus)
Using DNA sequence data, this work reports the first nearly complete species phylogeny of bumble bees, including most of the 250 known species from the 38 currently recognized subgenera, and provides a firm foundation for reclassification and for evaluating character evolution in the bumble Bees.

The distribution of bumblebee colour patterns worldwide: possible significance for thermoregulation, crypsis, and warning mimicry

The results using data for 632 worker patterns from all of the world’s bumblebee species show that: (1) there are many repeating colour patterns, forming relatively few groups of species with similar patterns; (2) colour-pattern groups can be recognized using simple rules; and (3) species within the 24 largest colour- pattern groups are significantly aggregated in particular areas of the World.
Selecting areas for species persistence using occurrence data
Bumblebee vulnerability and conservation world-wide
There is evidence that some bumblebee species are declining in Europe, North America, and Asia and it is recommended that live bumblebees should not be moved across continents or oceans for commercial pollination until proven safe.
Downscaling European species atlas distributions to a finer resolution: implications for conservation planning
Aim One of the limitations to using species' distribution atlases in conservation planning is their coarse resolution relative to the needs of local planners. In this study, a simple approach to…
Unveiling cryptic species of the bumblebee subgenus Bombus s. str. worldwide with COI barcodes (Hymenoptera: Apidae)
This is the first review of the entire subgenus Bombus to avoid fixed a priori assumptions concerning the limits of the problematic species and to diagnose all of the putative species throughout their global ranges and to map the extent of these geographic ranges.
Bumblebee Vulnerability: Common Correlates of Winners and Losers across Three Continents
Results of the meta-analysis of correlations showed support for the hypotheses that decline susceptibility is generally greater for species that have greater climatic specialization, for species in areas where they occur closest to the edges of their climatic ranges, and forspecies that have queens that become active later in the year.
Colour Patterns Do Not Diagnose Species: Quantitative Evaluation of a DNA Barcoded Cryptic Bumblebee Complex
The results presented here raise questions on the reliability of species determinations in previous studies and highlights the benefits of implementing DNA barcoding prior to ecological, taxonomic and conservation studies of these important key pollinators.
