Frontiers in Ecology and Evolution, 2023 Alpine bumble bees are the most important pollinators in temperate mountain ecosystems. Although they are used to encounter small-scale successions of very different climates in the mountains, many species respond sensitively to climatic changes ...

Frontiers in Environmental Science, 2016 Recent research has demonstrated colony-level sublethal effects of imidacloprid on bumble bees, affecting foraging and food consumption, and thus colony growth and reproduction, at lower pesticide concentrations than for honey bee colonies.

Honey bees exhibit greater patch fidelity than bumble bees when foraging in a common environment
Ecosphere, 2023 Animals commonly exhibit a tendency to return to previously visited locations. Such tendency is manifested at different scales, for example, fidelity to a site or fidelity to a specific patch within a site.

The Bumble Bees of Florida, Bombus spp.
EDIS, 2011 Bumble bees are easily recognized by the corbicula (pollen basket) on the hind tibiae in the females. They are beneficial insects that pollinate many native and ornamental plants.

Psyche: A Journal of Entomology, 2010 There are widespread concerns about declining populations of bumble bees due to conversion of native habitats to agroecosystems. Certain cropping systems, however, provide enormous foraging resources, and are beneficial for population build up of native ...

Flower Color as Predictor for Nectar Reward Quantity in an Alpine Flower Community
Frontiers in Ecology and Evolution, 2021 Entomophilous plants have evolved colorful floral displays to attract flower visitors to achieve pollination. Although many insects possess innate preferences for certain colors, the underlying proximate and ultimate causes for this behavior are still ...

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]
PLoS ONE, 2008 The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America ...

Morphological characterization and staging of bumble bee pupae [PDF]
PeerJ, 2018 Bumble bees (Hymenoptera: Apidae, Bombus) are important pollinators and models for studying mechanisms underlying developmental plasticity, such as factors influencing size, immunity, and social behaviors. Research on such processes, as well as expanding

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019 The study intended to compare repellency of three insecticides on bumble bees and honey bees in Norwegian red clover (Trifolium pratense L.) seed crops, and to examine effects of thiacloprid on bumble bee colony development in the field.

Cereal Chemistry, EarlyView.ABSTRACT Background and Objectives Copra meal is a byproduct of the coconut oil extraction process and provides an inexpensive source of energy for livestock diets. Single‐screw extrusion was conducted to investigate the effects of varying proportions of copra meal and distillers dried grains with solubles (DDGS) and the corresponding processing ...
