Taxonomic and functional diversity of urban bees of the world
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

ABSTRACT Microbial biostimulants offer sustainable alternatives to chemical fertilizers in legume cultivation by enhancing seed germination, nutrient uptake, and stress resilience, while maintaining the yield. However, their practical application is often limited by weak shelf life and reduced viability under environmental conditions. In this study, we

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.
