Compensation for wind drift by bumble-bees

, 1999
In his classic studies on honeybee navigation, von Frisch had to rely on qualitative visual observations of the bees' flight paths, but nevertheless reached the surprising conclusion that bees seem to anticipate lateral wind drift and compensate by ...

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Effects of climate change on phenologies and distributions of bumble bees and the plants they visit

Ecosphere, 2016
Surveys of bumble bees and the plants they visit, carried out in 1974 near the Rocky Mountain Biological Laboratory in Colorado, were repeated in 2007, thus permitting the testing of hypotheses arising from observed climate change over the intervening 33‐

Identities, concentrations, and sources of pesticide exposure in pollen collected by managed bees during blueberry pollination

Scientific Reports, 2021
Bees are critical for crop pollination, but there is limited information on levels and sources of pesticide exposure in commercial agriculture. We collected pollen from foraging honey bees and bumble bees returning to colonies placed in blooming ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Gender, violence, and killing: Revisiting femicide, and the overlooked realities of male victimization

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract The term femicide, widely used in reference to the “killing of a woman because she is a woman,” has been questioned on the ground that it implies unequal dignity of men and women victims of gender related death. This position called for an analysis of the terminology used to describe and define the various forms of killing of women and men. We

Species composition and elevational distribution of bumble bees (Hymenoptera, Apidae, Bombus Latreille) in the East Himalaya, Arunachal Pradesh, India [PDF]

ZooKeys, 2019
The East Himalaya is one of the world’s most biodiverse ecosystems. However, very little is known about the abundance and distribution of many plant and animal taxa in this region.

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

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.

No trade-off between learning speed and associative flexibility in bumblebees: a reversal learning test with multiple colonies [PDF]

, 2012
Potential trade-offs between learning speed and memory-related performance could be important factors in the evolution of learning. Here, we test whether rapid learning interferes with the acquisition of new information using a reversal learning paradigm.
