Microscale Plant Diversity in Traditional Wood‐Pastures

open access: yesApplied Vegetation Science, Volume 28, Issue 4, October/December 2025.
Solitary trees shape wood–pasture plant communities by altering light and soil nutrients conditions. While canopies favor few shade‐tolerant species, open areas support more diverse species, and together these contrasting communities enhance biodiversity and functional trait variation at the landscape scale.

Phylogenomics of Messor harvester ants (Hymenoptera: Formicidae: Stenammini) unravels their biogeographical origin and diversification patterns La phylogénomique des fourmis moissonneuses Messor (Hymenoptera: Formicidae: Stenammini) clarifie leur origine biogéographique et leurs patrons de diversification

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 1025-1040, October 2025.
Phylogenomic analysis of 2524 ultraconserved‐element loci from 58 Messor harvester ant species helps in redefining taxonomic groups of the genus. Messor ants emerged in the Irano‐Indian area around 20 million years ago, rapidly dispersing to the Western Palaearctic and Northeastern Africa during the early Miocene.

AI‐Driven Detection and Measurement of Keratinized Gingiva in Dental Photographs: Validation Using Reference Retainers

open access: yesJournal of Clinical Periodontology, Volume 52, Issue 7, Page 1056-1067, July 2025.
ABSTRACT Aim To evaluate a deep learning (DL) model for detecting keratinized gingiva (KG) in dental photographs and validate its clinical applicability using reference retainers for calibration. Materials and Methods A total of 576 sextant photographs were selected from 32 subjects, each with three sets of photographs: iodine‐stained, unstained and ...

Disentangling relationships in Euphorbia agraria s.l. (Euphorbiaceae) in south‐east Europe: One or two species?

open access: yesTAXON, Volume 74, Issue 3, Page 602-615, June 2025.
Abstract We explored the diversification of the south‐eastern and eastern European Euphorbia agraria s.l. applying molecular (amplified fragment length polymorphism [AFLP] fingerprinting and sequencing of the nuclear ribosomal internal transcribed spacer [ITS]), cytogenetic (relative genome size [RGS] estimations) and morphometric methods.
