Social information about others' affective states in a human‐altered world
Journal of Animal Ecology, EarlyView.Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Visual search and decision making in bees: time, speed and accuracy [PDF]
, 2006 An insect searching a meadow for flowers may detect several flowers from different species per second, so the task of choosing the right flowers rapidly is not trivial.

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia
Insect Science, EarlyView.This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

The role of automated feedback in training and retaining biological recorders for citizen science [PDF]
, 2016 The rapid rise of citizen science, with lay people forming often extensive biodiversity sensor networks, is seen as a solution to the mismatch between data demand and supply while simultaneously engaging citizens with environmental topics.

Seasonal variation in exploitative competition between honeybees and bumblebees
Oecologia, 2019 Honeybees (Apis mellifera) and bumblebees (Bombus spp.) often undergo exploitative competition for shared floral resources, which can alter their foraging behaviour and flower choice, even causing competitive exclusion.

Pollen from multiple sunflower cultivars and species reduces a common bumblebee gut pathogen [PDF]
Royal Society Open Science, 2019 Pathogens are one of the factors driving pollinator declines. Diet can play an important role in mediating pollinator health and resistance to pathogens. Sunflower pollen (Helianthus annuus) dramatically reduced a gut pathogen (Crithidia bombi) of Bombus

Low dose of neonicotinoid insecticide reduces foraging motivation of bumblebees
Proceedings of the Royal Society B: Biological Sciences, 2018 Widespread use of neonicotinoid insecticides, such as imidacloprid, is often associated with diminishing populations of bees; this loss of pollinators presents a concern for food security and may cause unpredictable changes in ecological networks ...
