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.

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

open access: yes, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Macronutrient composition in pollen affects development and survival in wild bees

open access: yesPhysiological Entomology, Volume 51, Issue 2, Page 350-362, June 2026.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Pollinator conservation paradox: Exotic wildflowers provision native pollinators under anthropogenic changes

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Invasive wildflowers pose a conservation paradox: While they often reduce the diversity and abundance of native wildflowers, they can provide resources for native pollinators, including imperiled species. Previous work has framed wildflower invasions as outcomes of global change, but less is known about how interacting anthropogenic drivers ...

Spatial ecology of a range-expanding bumble bee pollinator [PDF]

open access: yes, 2019
Molecular methods have greatly increased our understanding of the previously cryptic spatial ecology of bumble bees (Bombus spp.), with knowledge of the spatial ecology of these bees being central to conserving their essential pollination services ...

Fine‐Scale Temporal Dynamics of the Honey Bee Hive Microbiome and Foraging Revealed by Airborne eDNA

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Airborne eDNA collected within honey bee hives reveals diverse plant and microbial communities. While richness remains stable, seasonal shifts in plant and microbiome composition highlight dynamic resource use, demonstrating eDNA's potential for non‐invasive, fine‐scale monitoring of foraging and colony health. ABSTRACT Environmental DNA (eDNA) has the

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

Bumble bees in landscapes with abundant floral resources have lower pathogen loads

open access: yesScientific Reports, 2020
The pollination services provided by bees are essential for supporting natural and agricultural ecosystems. However, bee population declines have been documented across the world.
