Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Unveiling of climate change-driven decline of suitable habitat for Himalayan bumblebees

Scientific Reports
Insect pollinators, especially bumblebees are rapidly declining from their natural habitat in the mountain and temperate regions of the world due to climate change and other anthropogenic activities.

The Path to Sustainability: Apricot Growers' Willingness to Adopt Agroecological Practises in Malatya, Türkiye

Sustainable Development, EarlyView.
ABSTRACT The global food system faces sustainability, safety, and equity challenges. Agroecological practises offer solutions through sustainable production and resource conservation. This study examines apricot producers' willingness to adopt agricultural practises in Malatya, Türkiye, focusing on their attitudes, behaviours and the factors ...

Chemotaxonomical characterisation of males of Bombus lucorum (Hymenoptera: Apidae) collected in the Czech Republic

European Journal of Entomology, 2001
Labial gland secretions of 26 males of the bumblebee Bombus lucorum (L.), collected in the Czech Republic, were analysed. The secretions consisted of 60 compounds; ethyl (Z)-9-tetradecenoate was the main component (average 53%). Although the males varied

Cognitive dimensions of predator responses to imperfect mimicry? [PDF]

, 2007
Many palatable insects, for example hoverflies, deter predators by mimicking well-defended insects such as wasps. However, for human observers, these flies often seem to be little better than caricatures of wasps – their visual appearance and ...

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.

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

First molecular detection of co-infection of honey bee viruses in asymptomatic Bombus atratus in South America

Brazilian Journal of Biology
Pollination is critical for food production and has the particularity of linking natural ecosystems with agricultural production systems. Recently, losses of bumblebee species have been reported worldwide.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L. [PDF]

New Phytol
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

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 ...
