Repellency of insecticides and the effect of thiacloprid on bumble bee colony development in red clover (Trifolium pratense L.) seed crops

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.

Contrasting effects of land cover on nesting habitat use and reproductive output for bumble bees

bioRxiv, 2020
Understanding habitat quality is central to understanding the distributions of species on the landscape, as well as to conserving and restoring at-risk species. Although it is well-known that many species require different resources throughout their life

Widespread contamination of wildflower and bee-collected pollen with complex mixtures of neonicotinoids and fungicides commonly applied to crops [PDF]

, 2016
There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realistic levels of exposure. Here, we quantify concentrations of

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 ...

Manipulation of carbohydrate diet and ensuing changes in weight and glycogen storage in bumble bee (Bombus impatiens) queens [PDF]

, 2014
Bumble bees serve as important pollinators for human crops, but many of their populations have declined over the past 60 years. Bumble bee population decline is very important for humans because it reduces pollination services, which can lead to lower ...

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.

On the Proper Treatment of Dynamics in Cognitive Science

Topics in Cognitive Science, EarlyView., 2023
Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...
