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.

Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
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 ...

Mixed effects of urbanization on pollination services among four native plant species

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1184-1195, December 2025.
We tested urbanization and fragmentation effects on pollination services using four native phytometer species that were deployed across 10 community gardens located in suburban and densely urbanized areas Landscape context generally did not influence pollination; however, for one of four phytometers (Lobelia siphilitica, pictured above) urban cover ...

Pollen exploitation by non‐native, feral honey bees: Potential consequences for interspecific competition

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1109-1119, November 2025.
In Southern California, a global hotspot of bee biodiversity, predominantly feral populations of the exotic western honey bee constitute an estimated 90% of individual bees and 98% of bee biomass. Honey bee foragers remove 80% of total pollen during the first day flowers open on three common native species, with their first two visits removing over 60%

24 million years of pollination interaction between European linden flowers and bumble bees

open access: yesNew Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.
