Equivocal evidence for colony level stress effects on bumble bee pollination services [PDF]

, 2020
Climate change poses a threat to global food security with extreme heat events causing drought and direct damage to crop plants. However, by altering behavioural or physiological responses of insects, extreme heat events may also affect pollination ...

Elevated Temperature May Affect Nectar Microbes, Nectar Sugars, and Bumble Bee Foraging Preference

Microbial Ecology, 2021
Floral nectar, an important resource for pollinators, is inhabited by microbes such as yeasts and bacteria, which have been shown to influence pollinator preference. Dynamic and complex plant-pollinator-microbe interactions are likely to be affected by a

Bumble bee species distributions and habitat associations in the Midwestern USA, a region of declining diversity

Biodiversity and Conservation, 2021
Bumble bees (Bombus spp.) are important pollinators, yet rapidly declining globally. In North America some species are thriving while others are nearing extinction. Recognizing subtle differences in species’ biology and responses to environmental factors

Introduced honey bees increase host plant abundance but decrease native bumble bee species richness and abundance

Ecosphere, 2022
Long‐term variation in the population density of introduced honey bees (Apis mellifera) has been shown to be associated with variations in floral traits in alpine lotus (Saussurea nigrescens).

Decline and Conservation of Bumble Bees [PDF]

Annual Review of Entomology, 2008
Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely ...

Endosymbionts that threaten commercially raised and wild bumble bees (Bombus spp.)

Journal of Pollination Ecology, 2023
Bumble bees (Bombus spp.) are important pollinators for both wild and agriculturally managed plants. We give an overview of what is known about the diverse community of internal potentially deleterious bumble bee symbionts, including viruses, bacteria ...

An organizing feature of bumble bee life history: worker emergence promotes queen reproduction and survival in young nests

Conservation Physiology, 2021
The emergence of workers in young bumble bee nests promotes queen physiological changes related to early nesting success. Our findings underline the importance of conservation interventions for bumble bees that support the early nesting period and ...

Bumble bee forager abundance on lowland heaths is predicated by specific floral availability rather than the presence of honey bee foragers: evidence for forage resource partitioning

Journal of Pollination Ecology, 2018
Honey bees are being scrutinized for their potential impact upon wild bees. In lowland heath mosaics, a simple but resource rich habitat for pollinators, there is a higher probability of niche overlap for bumble bees and honey bees due to the requirement

Colonies of Bumble Bees (Bombus impatiens) Produce Fewer Workers, Less Bee Biomass, and Have Smaller Mother Queens Following Fungicide Exposure

Insects, 2015
Bees provide vital pollination services to the majority of flowering plants in both natural and agricultural systems. Unfortunately, both native and managed bee populations are experiencing declines, threatening the persistence of these plants and crops.
