Biogeographic parallels in thermal tolerance and gene expression variation under temperature stress in a widespread bumble bee

Scientific Reports, 2020
Global temperature changes have emphasized the need to understand how species adapt to thermal stress across their ranges. Genetic mechanisms may contribute to variation in thermal tolerance, providing evidence for how organisms adapt to local ...

Local management and landscape effects on diversity of bees, wasps and birds in urban green areas [PDF]

, 2008
Today almost all ecosystems on Earth are directly or indirectly influenced by human activity. Most species occur in ecosystems that are managed by humans and only a small fraction of biodiversity exists in protected areas.

Big bees do a better job : intraspecific size variation influences pollination effectiveness

, 2014
Funding: School of Biology, University of St AndrewsBumblebees (Bombus spp.) are efficient pollinators of many flowering plants, yet the pollen deposition performance of individual bees has not been investigated.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Identifying conservation priority areas for North American bumble bee species in Canada under current and future climate scenarios

Conservation Science and Practice, 2023
Many bumble bee species are declining globally from multiple threats including climate change. Identifying conservation priority areas with a changing climate will be important for conserving bumble bee species. Using systematic conservation planning, we

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Coinvasional disruptions to island pollinator networks

Conservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Bumble bee nest thermoregulation: a field study

Journal of Apicultural Research, 2023
Careful control of brood temperature is important for successful colony development in social insects. Six bumble bee colonies of six common Central European species (B. hypnorum, B. hortorum, B. argillaceus, B. pascuorum, B. humilis, B. sylvarum) were continuously monitored for several weeks.

Strategic conservation prioritization through creating and updating the regional species of greatest conservation need list in the northeastern United States

Conservation Science and Practice, EarlyView.
Biodiversity is declining globally, underscoring the need for conservation strategies informed by regional expertise. In the northeastern United States, 14 state wildlife agencies and taxonomic experts developed the Regional Species of Greatest Conservation Need (RSGCN) list, revealing that global and national datasets captured only ~55% of regionally ...

Wildfire reveals transient changes to individual traits and population responses of a native bumble bee (Bombus vosnesenskii).

Journal of Animal Ecology, 2020
Fire-induced changes in the abundance and distribution of organisms, especially plants, can alter resource landscapes for mobile consumers driving bottom-up effects on their population sizes, morphologies, and reproductive potential.
