Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

The conservation of bumble bees [PDF]

open access: yesBee World, 2003
The approximately 250 known species of bumble bee (genus Bombus) are found predominantly in temperate regions of the northern hemisphere. This region also contains much of the world's human population and the most intensive agricultural regions. Probably as a result of this, many bumble bees appear to be undergoing dramatic declines in range.

Floral resource availability and surrounding land cover influence bumble bee community composition in an agricultural landscape

open access: yesInsect Conservation and Diversity, EarlyView.
Multispecies occupancy models indicated that the occurrence of bumble bees was associated with local floral resources as well as the landscape surrounding a site within 1.6 km. Estimated species richness was greater at sites with more forest cover and lower at sites with more corn and soybean agriculture in the surrounding landscape.

De Novo Genome Assemblies for Three North American Bumble Bee Species: Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii

open access: yesG3: Genes, Genomes, Genetics, 2020
Bumble bees are ecologically and economically important insect pollinators. Three abundant and widespread species in western North America, Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii, have been the focus of substantial research ...

Bridging the implementation gap in MCABC inventory management: from a taxonomy to practical archetypes

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Despite increasing demands for resilient and sustainable supply chains, inventory management often relies on outdated single‐criterion analyses. While multi‐criteria ABC (MCABC) analyses provide a theoretically mature assessment of resilience‐sustainability‐benefit trade‐offs in inventory, their adoption remains limited due to fragmented ...

The Form of Agency

open access: yesNoûs, EarlyView.
ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

Animal Logic: Locke and the Nature of Inference

open access: yesNoûs, EarlyView.
ABSTRACT Can animals reason? If so, what would their reasoning consist in, and how, if at all, would it differ from its human counterpart? On these questions, John Locke stakes out a position that also merits consideration today. I argue that, for Locke, reasoning is a matter of the subject's construing her mental states as support for a conclusion ...

Impact of Bee Species and Plant Density on Alfalfa Pollination and Potential for Gene Flow

open access: yesPsyche: A Journal of Entomology, 2010
In outcrossing crops like alfalfa, various bee species can contribute to pollination and gene flow in seed production fields. With the increasing use of transgenic crops, it becomes important to determine the role of these distinct pollinators on alfalfa

Bumble bee abundance and diversity increase with the intensity of tallgrass prairie restoration intervention

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Human land use intensification and the resulting habitat loss are primary drivers of insect pollinator declines. Habitat restoration offers a promising approach to counteract these declines, yet landscape‐level evaluations of bee responses to restoration and management remain limited.

Comparison of seasonal viral prevalence supports honey bees as potential spring pathogen reservoirs for bumble bees

open access: yesEcosphere
Bee declines pose a serious risk to agricultural sustainability, wild plant diversity, and the commercial bee industry, generating local and global concerns about bee health. Parasites, including micro‐parasites and macro‐parasites, negatively impact bee
