Can the nutritional geometric framework unveil how macronutrients in pollen shape solitary bee foraging and survival? Open
The nutritional geometric framework (NGF) hypothesizes that animals forage to achieve specific macronutrient ratios. Pollen, the primary source of protein and lipids for bees, varies in nutritional content across plant species. Studies sug…

Sexual selection drives the speciation of lineages with contrasting mating systems Open
Repeated shifts in ecological strategies often lead to consistent speciation patterns across phylogenies. One example is the transition from outcrossing to self-fertilization in plants, which generally results in the reproductive isolation…

Foraging bee species differentially prioritize quantity and quality of floral rewards Open
Pollinator–plant interactions represent a core mutualism that underpins biodiversity in terrestrial ecosystems, and the loss of flowering plants is a major driver of pollinator declines. Bee attraction to flowers is mediated by both quanti…

Deep learning object detection to estimate the nectar sugar mass of flowering vegetation Open
Floral resources are a key driver of pollinator abundance and diversity, yet their quantification in the field and laboratory is laborious and requires specialist skills. Using a dataset of 25,000 labelled tags of fieldwork‐realistic quali…

Agri‐environment schemes targeting farmland bird populations also provide food for pollinating insects Open
Farmland biodiversity has declined over the past few decades. European Common Agricultural Policy encourages farmers to set up agri‐environment schemes (AES) that support biodiversity and associated ecosystem services such as pollination. …

Estimation of pollinating insect populations in agro-ecosystems : comparing oilseed-rape fields and AES flower-strips Open
Since 2005, flower-strip Agri-Environment Schemes (AES) are subsidised in Wallonia to create insect friendly areas in fields. Flower-strips can benefit pollinator insects, which can be needed by entomophilous crops as Brassica napus. But i…

Molecular taxonomic analysis of the plant associations of adult pollen beetles (Nitidulidae: Meligethinae), and the population structure of <i>Brassicogethes aeneus</i> Open
Pollen beetles (Nitidulidae: Meligethinae) are among the most abundant flower-visiting insects in Europe. While some species damage millions of hectares of crops annually, the biology of many species is little known. We assessed the utilit…

Food for Pollinators: Quantifying the Nectar and Pollen Resources of Urban Flower Meadows Open
Planted meadows are increasingly used to improve the biodiversity and aesthetic amenity value of urban areas. Although many 'pollinator-friendly' seed mixes are available, the floral resources these provide to flower-visiting insects, and …
