    Genetic diversity and differentiation among insular honey bee populations in the southwest Indian Ocean likely reflect old geographical isolation and modern introductions With globalization the Western honey bee has become a nearly cosmopolitan species, but it was originally restricted to the...

    Microsatellite Analysis of Museum Specimens Reveals Historical Differences in Genetic Diversity between Declining and More Stable Bombus Species Worldwide most pollinators, e.g. bumblebees, are undergoing global declines. Loss of genetic diversity can play an essential role in these observed...

    Spatial Heterogeneity Regulates Plant-Pollinator Networks across Multiple Landscape Scales Mutualistic plant-pollinator interactions play a key role in biodiversity conservation and ecosystem functioning. In a community, the combination of these interactions can generate emergent properties...

    Dance Communication Affects Consistency, but Not Breadth, of Resource Use in Pollen-Foraging Honey Bees In groups of cooperatively foraging individuals, communication may improve the group’s performance by directing foraging effort to where it is most useful. Honey bees (Apis mellifera) use a...

    Hidden Diversity in Honey Bee Gut Symbionts Detected by Single-Cell Genomics Microbial communities in animal guts are composed of diverse, specialized bacterial species, but little is known about how gut bacteria diversify to produce genetically and ecologically distinct entities. The gut...

    Decreasing Abundance, Increasing Diversity and Changing Structure of the Wild Bee Community (Hymenoptera: Anthophila) along an Urbanization Gradient Background Wild bees are important pollinators that have declined in diversity and abundance during the last decades. Habitat destruction and...

    Bee Species Diversity Enhances Productivity and Stability in a Perennial Crop Wild bees provide important pollination services to agroecoystems, but the mechanisms which underlie their contribution to ecosystem functioning—and, therefore, their importance in maintaining and enhancing these...

    Evidence for intra-colonial genetic variance in resistance to American foulbrood of honey bees ( Apis mellifera): further support for the parasite/pathogen hypothesis for the evolution of polyandry. Palmer KA1, Oldroyd BP. Author information Abstract Explanations for the evolution of...

    Plant-Pollinator Coextinctions and the Loss of Plant Functional and Phylogenetic Diversity Plant-pollinator coextinctions are likely to become more frequent as habitat alteration and climate change continue to threaten pollinators. The consequences of the resulting collapse of plant communities...

    Influence of Pollen Nutrition on Honey Bee Health: Do Pollen Quality and Diversity Matter? The beneficial influence of pollen availability on bee health is well-established but whether quality and diversity of pollen diets can modify bee health remains largely unknown. We therefore tested the...

    Lack of Variation at Phosphoglucose Isomerase (Pgi) in Bumblebees: Implications for Conservation Genetics Studies A goal of modern conservation genetics is to address the extent to which adaptive variation, especially for loci where polymorphism should be maintained, is affected by the forces...

    Plant Pollinator Networks along a Gradient of Urbanisation Habitat loss is one of the principal causes of the current pollinator decline. Along an urbanisation gradient comprising four types of landscape contexts (semi-natural, agricultural, suburban, urban), we set up experimental plant...
  14. The Queen & Bee Breeding
    The last two years I have bought or traded with neighboring beekeepers for a frame of eggs and brood in order to pull queens from them. I have done this in an effort to diversify the genetics in my yard with other bee stock that has done well in our climate. This year, I know five local...

    Multiple Mating But Not Recombination Causes Quantitative Increase in Offspring Genetic Diversity for Varying Genetic Architectures Experimental studies that compared genetically diverse colonies produced by multiply-mated queens to genetically more homogeneous colonies that were produced by...
