Mapping species distributions: A comparison of skilled naturalist and lay citizen science recording [PDF]

, 2015
To assess the ability of traditional biological recording schemes and lay citizen science approaches to gather data on species distributions and changes therein, we examined bumblebee records from the UK’s national repository (National Biodiversity ...

Discriminations of Color and Pattern on Artificial Flowers by Male and Female Bumble Bees, \u3ci\u3eBombus Impatiens\u3c/i\u3e (Hymenoptera: Apidae) [PDF]

, 2018
This study examined the performance of male bumble bees (Bombus impatiens) in color and pattern discriminations and compared it to that of female bees. Bees were trained to forage from rewarding (S+) and unrewarding (S-) artificial flowers which differed

Bumblebees [PDF]

, 2010
Since bumblebees are a group associated with cool climates, Britain supports a large proportion (~10%) of the world's bumblebee fauna. However, three of our 25 species have become extinct, and seven species are Biodiversity Action Plan (BAP) listed, a higher proportion than for any other insect group.

Equivocal Evidence for Colony Level Stress Effects on Bumble Bee Pollination Services

Insects, 2020
Climate change poses a threat to global food security with extreme heat events causing drought and direct damage to crop plants. However, by altering behavioural or physiological responses of insects, extreme heat events may also affect pollination ...

Wild bee toxicity data for pesticide risk assessments [PDF]

, 2019
Pollination services are vital for agriculture, food security and biodiversity. Although many insect species provide pollination services, honeybees are thought to be the major provider of this service to agriculture. However, the importance of wild bees

The heat is on: reduced detection of floral scents after heatwaves in bumblebees

Proceedings of the Royal Society B
Global climate change disrupts key ecological processes and biotic interactions. The recent increase in heatwave frequency and severity prompts the evaluation of physiological processes that ensure the maintenance of vital ecosystem services such as ...

Does bumblebee preference of continuous over interrupted strings in string-pulling tasks indicate means-end comprehension?

eLife
Bumblebees (Bombus terrestris) have been shown to engage in string-pulling behavior to access rewards. The objective of this study was to elucidate whether bumblebees display means-end comprehension in a string-pulling task.

Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]

, 2017
For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.
