Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

open access: yesJournal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Phylogenetic Relationships of Plant Bugs Based on Mitochondrial Genomes (Heteroptera: Miridae)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study for the first time employs mitochondrial genomes to resolve Miridae phylogeny, with 42 species spanning 39 genera across six of the seven currently recognized subfamilies. Bryocorinae is paraphyletic as the stem groups of Miridae. These findings provide a progressive phylogenetic framework with new significance for the future phylogenetic ...

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.
