Animal Conservation, Volume 28, Issue 4, Page 501-514, August 2025.Climate change (CC) and land‐use/cover change (LUCC) are threatening species worldwide, with amphibians and reptiles being particularly vulnerable. In Cilento, a highly biodiverse Mediterranean area in the southern Appenine protected by a National Park and 30 Natura 2000 Network sites, 11 amphibians and 16 reptiles could disappear in the future ...

The Chemical and Evolutionary Ecology of Tetrodotoxin (TTX) Toxicity in Terrestrial Vertebrates
Marine Drugs, 2010 Tetrodotoxin (TTX) is widely distributed in marine taxa, however in terrestrial taxa it is limited to a single class of vertebrates (Amphibia). Tetrodotoxin present in the skin and eggs of TTX-bearing amphibians primarily serves as an antipredator ...

Zoodiversity, 2023 The endangered Caucasian salamander, Mertensiella caucasica (Waga, 1876), is endemic to the western Lesser Caucasus. Here, we used N-mixed models to analyse repeated count data of Caucasian salamanders from the eastern Black Sea region of Turkey.

Genetic Divergence for the Amphibian Pleurodeles waltl in Southwest Portugal: Dispersal Barriers Shaping Geographic Patterns [PDF]
, 2014 Dispersal and vicariance are the principal mechanisms responsible for the formation of biogeographic patterns, driven or maintained by the role of past and current barriers to dispersal.

Evolution of skull shape in the family Salamandridae (Amphibia: Caudata) [PDF]
Journal of Anatomy, 2017 AbstractWe carried out a comparative morphometric analysis of 56 species of salamandrid salamanders, representing 19 out of 21 extant genera, with the aim of uncovering the major patterns of skull shape diversification, and revealing possible trends and directions of evolutionary change.

Complete metamorphosis promotes morphological and functional diversity in Caudata
Functional Ecology, Volume 39, Issue 7, Page 1732-1747, July 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Metamorphosis, a common and spectacular developmental process, involves major phenotypic changes often linked to environmental transitions. Understanding how these changes affect morphological evolution is crucial for examining metamorphosis's evolutionary impacts.

Phenotypic flexibility of gape anatomy fine-tunes the aquatic prey-capture system of newts [PDF]
, 2016 A unique example of phenotypic flexibility of the oral apparatus is present in newts (Salamandridae) that seasonally change between an aquatic and a terrestrial habitat.

Zoologica Scripta, Volume 54, Issue 4, Page 473-486, July 2025.Abstract Relief has a profound impact on the genetic structure of species. While the geographic ordination of genetic variation is assessed in many mountain species, the factors involved in phenotypic differentiation and its congruence with phylogeographic history have been largely underexplored. This is the case of the genus Calotriton.
