A trait‐based framework to understand and predict the response of wild bee functional groups to anthropogenic landscapes

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 56-71, January 2026.
Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

open access: yesInsect Science, Volume 32, Issue 6, Page 1911-1925, December 2025.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

Co‐flowering with congeners does not affect buzz‐pollinator specialization and pollination performance in Rhexia mariana, but does affect floral trait variance

open access: yesAmerican Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise Pollinator‐mediated plant‐plant interactions may be negative (i.e., competition, reproductive interference) or positive (i.e., facilitation). Especially when co‐flowering with close relatives (e.g., congeners), negative interactions through reproductive interference may be strong and result in floral trait divergence and increased ...
