Phylogeography and ecology of bumble bees on Kolguev Island, a remote European Arctic landmass [PDF]

ZooKeys, 2022
The bumble bee fauna of the Russian Arctic is rather poorly known. Kolguev Island, a remote insular territory in the Barents Sea, is one of the deficiently studied areas.

Landscape-scale floral resource discontinuity decreases bumble bee occurrence and alters community composition.

Ecological Applications, 2023
Agricultural practices and intensification over the past two centuries have dramatically altered the abundance and temporal continuity of floral resources that support pollinating insects such as bumble bees.

An Evidence-based rationale for a North American commercial bumble bee clean stock certification program

Journal of Pollination Ecology, 2023
The commercial production and subsequent movement of bumble bees for pollination of agricultural field and greenhouse crops is a growing industry in North America and globally.

Assessing the potential for deep learning and computer vision to identify bumble bee species from images

Scientific Reports, 2021
Pollinators are undergoing a global decline. Although vital to pollinator conservation and ecological research, species-level identification is expensive, time consuming, and requires specialized taxonomic training.

The abundance and pollen foraging behaviour of bumble bees in relation to population size of whortleberry (Vaccinium uliginosum). [PDF]

PLoS ONE, 2012
Habitat fragmentation can have severe effects on plant pollinator interactions, for example changing the foraging behaviour of pollinators. To date, the impact of plant population size on pollen collection by pollinators has not yet been investigated ...

Differences in EAG Response and Behavioral Choices between Honey Bee and Bumble Bee to Tomato Flower Volatiles

Insects, 2022
Simple Summary Tomatoes are a popular crop, and bumble bees and honey bees are its main pollinators. Floral scent usually plays an important role in mediating the foraging behavior of bees, and tomato flowers release special scents.

Protocol for Initiating and Monitoring Bumble Bee Microcolonies with Bombus impatiens (Hymenoptera: Apidae)

Bio-Protocol, 2022
Populations of some bumble bee species are in decline, prompting the need to better understand bumble bee biology and for assessing the effects of environmental stressors on these important pollinators.

Climate driven disruption of transitional alpine bumble bee communities

Global Change Biology, 2022
Pollinators at high elevations face multiple threats from climate change including heat stress, failure to phenological match advancing flower resources and competitive pressure from range‐expanding species of lower elevations.

Parasites, parasitoids, and hive products that are potentially deleterious to wild and commercially raised bumble bees (Bombus spp.) in North America

Journal of Pollination Ecology, 2023
Bumble bees are important pollinators for a great diversity of wild and cultivated plants, and in many parts of the world certain species have been found to be in decline, gone locally extinct, or even globally extinct.

Exposure to urban heavy metal contamination diminishes bumble bee colony growth

Urban Ecosystems, 2022
As a result of their industrial past, legacy cites often have elevated concentrations of soil heavy metal contamination. Metal pollution can have negative and prolonged ecosystem impacts, and bees that forage in these urban ecosystems are at risk of ...
