DOI: 10.1002/ece3.9560
Abstract: Abstract Bumble bees are key pollinators with some species reared in captivity at a commercial scale, but with significant evidence of population declines and with alarming predictions of substantial impacts under climate change scenarios. While… read more here.

DOI: 10.1002/ece3.9743
Abstract: Abstract Bumble bees are important pollinators in temperate forested regions where fire is a driving force for habitat change, and thus understanding how these insects respond to fire is critical. Previous work has shown bees… read more here.

DOI: 10.1002/ecy.2503
Abstract: Hotspots of disease transmission can strongly influence pathogen spread. Bee pathogens may be transmitted via shared floral use, but the role of plant species and floral trait variation in shaping transmission dynamics is almost entirely… read more here.

DOI: 10.1002/ecy.2946
Abstract: Resource availability has been disturbed for many organisms in agricultural landscapes including pollinator species. Abundance and diversity in flower availability benefit bee populations, however, little is known about which of protein or carbohydrate resources may… read more here.

DOI: 10.1002/ecy.3712
Abstract: Environmental gradients generate and maintain biodiversity on Earth. Mountain slopes are among the most pronounced terrestrial environmental gradients, and the elevational structure of species and their interactions can provide unique insight into the processes that… read more here.

DOI: 10.1002/jwmg.21280
Abstract: Bumble bees (Bombus spp.) are declining across many regions in the Northern Hemisphere, leading to a need for management actions that will protect and enhance their habitats. In the Sierra Nevada of California, USA, montane… read more here.

DOI: 10.1002/ps.4756
Abstract: BACKGROUND In recent years, concern has been raised over honey bee colony losses, and also among wild bees there is evidence for extinctions and range contractions in Europe and North America. Pesticides have been proposed… read more here.

DOI: 10.1007/s00265-017-2328-y
Abstract: The associative learning of spatial and reward information is generally considered an adaptive behavior of foraging animals that collect food from renewable resources. However, learning may not always maximize foraging efficiency if choosing a high-reward… read more here.

DOI: 10.1007/s10905-021-09790-0
Abstract: Social insects have high levels of cooperation and division of labor. In bumble bees this is partly size-based, with larger bees performing tasks outside the nest and smaller bees remaining inside, although bumble bees still… read more here.

DOI: 10.1016/j.jinsphys.2017.06.014
Abstract: Exposure to carbon dioxide (CO2) has pleiotropic effects in many insect species, ranging from eliciting rapid behavioral responses such as attraction, to dramatic physiological changes, including ovary activation. In bumble bees, CO2 narcosis causes queens… read more here.
