Cranial Morphology of the Carboniferous-Permian Tetrapod Brachydectes newberryi (Lepospondyli, Lysorophia): New Data from µCT. [PDF]
PLoS ONE, 2016 Lysorophians are a group of early tetrapods with extremely elongate trunks, reduced limbs, and highly reduced skulls. Since the first discovery of this group, general similarities in outward appearance between lysorophians and some modern lissamphibian ...

Integrative Conservation, Volume 4, Issue 3, Page 442-463, September 2025.In this study, we analyze the conservation status of Ethiopia's amphibian and reptile diversity in terms of coverage with protected areas and global representation in conservation breeding facilities. We identify conservation gaps and suggest priorities for improvement.

Evolutionary diversification of epidermal barrier genes in amphibians
Scientific Reports, 2022 The epidermal differentiation complex (EDC) is a cluster of genes encoding components of the skin barrier in terrestrial vertebrates. EDC genes can be categorized as S100 fused-type protein (SFTP) genes such as filaggrin, which contain two coding exons ...

Developmental Dynamics, Volume 254, Issue 8, Page 887-901, August 2025.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Generation length of the world's amphibians and reptiles
Ecography, Volume 2025, Issue 7, July 2025.Variation in life histories influences demographic processes, from adaptive changes to population declines leading to extinction. Among life history traits, generation length offers a critical feature to forecast species' demographic trajectories such as population declines (widely used by the IUCN Red List) and adaptability to environmental change ...
