Government-run agri-environment schemes (AES) have the potential to restore the local landscape to benefit bees. Bee abundance, species richness and foraged plants were surveyed over a season on 18 farms in Shropshire, UK, classified into three treatment groups for comparison: Conventional, Entry-...
In still other ecosystems , honey bees appear not to be as influential as in the Canary Islands. After introduction in northern Patagonia, nonnative bumble bees and honey bees overtook the native bees as the most frequent floral visitors, but this had no effect on the native bees’ actual vis...

Bees are fundamental insects in agroecosystems, mainly due to pollination. However, its decline has been observed in recent years, and the contamination by
Presumably, queenless colonies emit a chemical signal into the environment that lures the males to the nest, but the chemical identity and source of this signal has not been identified (Bueno et al.2022a). Three hypotheses have been suggested to explain male attraction to nests that are re-qu...

1). We found that increasing pesticide risk reduced bumble bee colony production (summed eclosed and closed cocoons of all castes; Methods) and this effect was modified by an interaction with the proportion of cropland in the surrounding landscape (Fig. 1b and Table 1; generalized linear ...
