Phylogeography and Contact Zones of the Common Grass Snake in Poland (Squamata: Natricidae: Natrix natrix)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Until now, the genetic identity of common grass snakes (Natrix natrix) in Poland remained poorly understood. This study presents the first comprehensive phylogeographic analysis for Poland using mitochondrial DNA sequences (cyt b and ND4 + tRNAs) and 13 nuclear microsatellite loci.

Freshwater amphibians and squamates from Villeveyrac (lower Campanian; Hérault, France): palaeodiversity, palaeoenvironment and implications for the Late Cretaceous palaeobiogeography of the European herpetofauna

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...

Blood Parasites and Wildlife: The Development of a Discipline

open access: yesIntegrative Zoology, Volume 21, Issue 1, Page 2-10, January 2026.
Changes in our knowledge on blood parasite infections of wild animals in the last 30 years is reviewed with emphasis on taxonomy and phylogeny, impact of infections on fitness, and distribution of blood parasites. ABSTRACT In the last 30 years, the area of the study of parasitism caused by blood parasite infections on wildlife has suffered an ...

A Palaeogene stem crotaphytid (Aciprion formosum) and the phylogenetic affinities of early fossil pleurodontan iguanians

open access: yesRoyal Society Open Science
Pleurodonta is an ancient, diverse clade of iguanian lizard distributed primarily in the Western Hemisphere. Although the clade is a frequent subject of systematic research, phylogenetic resolution among the major pleurodontan clades is elusive.
