Substantial variability in morphological scaling among bumblebee colonies

Royal Society Open Science, 2022
Differences in organ scaling among individuals may play an important role in determining behavioural variation. In social insects, there are well-documented intraspecific differences in colony behaviour, but the extent that organ scaling differs within ...

Proximity to wind turbines altered plant–pollinator dynamics in prairie and sagebrush ecosystems in Wyoming, USA

Nordic Journal of Botany, EarlyView.
Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...

Super-entropy bumblebee AdS black holes

Physics Letters B
Motivated by the effect of the bumblebee field on thermodynamic instability in (non)extended phase space, we study the thermodynamic instability for the bumblebee AdS black holes. For this purpose, first, we evaluate the effect of the bumblebee field (or

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

Oikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

A Sublethal Concentration of Sulfoxaflor Has Minimal Impact on Buff-Tailed Bumblebee (Bombus terrestris) Locomotor Behaviour under Aversive Conditioning

Toxics, 2023
Pesticide exposure has been cited as a key threat to insect pollinators. Notably, a diverse range of potential sublethal effects have been reported in bee species, with a particular focus on effects due to exposure to neonicotinoid insecticides.

Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Declining bumblebee (Bombus) species richness and abundance with increasing sheep grazing intensity on traditional Norwegian summer farms

Ecological Solutions and Evidence
Semi‐natural grasslands are valuable habitat for bumblebees (Bombus spp.) in Fennoscandia. These grasslands are often maintained by livestock such as free‐ranging sheep, but it is unclear if sheep grazing impacts bumblebee communities, and if so, which ...

Bumblebee Abundance in Species-Rich Grasslands in Southern Sweden Decreases with Increasing Amount of Arable Land at a Landscape Level

Insects
Conservation of bumblebee populations is essential because of their role as pollinators. Declines in bumblebee abundance have been documented in recent decades, mostly attributed to agricultural intensification, landscape simplification and loss of semi ...

Robotics for Crop Pollination: Recent Advances and Future Direction

Journal of Field Robotics, EarlyView.
ABSTRACT There is great interest in alternative pollination strategies for crop production in the face of climate change and perennial threats to the traditional pollination mechanisms. This review explores the potential of robotic pollination as a promising solution to these challenges affecting crop fertilization, agricultural sustainability, and ...

The Role of Pathogens in Bumblebee Decline: A Review

Pathogens
Bumblebees, the most important wild pollinators in both agricultural and natural ecosystems, are declining worldwide. The global decline of bumblebees may threaten biodiversity, pollination services, and, ultimately, agricultural productivity.
