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

Systematic 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 ...

Pollination biology and reproductive ecology of critically endangered endemic Campanula teucrioides in western Anatolia

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.
Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined

Estimating the ecological drivers of insect abundance when detection is imperfect

Journal of Animal Ecology, Volume 94, Issue 12, Page 2641-2654, December 2025.
Using a field‐based mark–recapture approach, the authors demonstrate that habitat quality can simultaneously influence insect abundance and detection. Simulation also showed that prioritizing increased sampling intensity over adding more study sites can improve accuracy of standard modelling approaches including GLMs or GLMMs, which do not account for ...
