Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

open access: yesJournal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

open access: yesEcography, Volume 2026, Issue 10, October 2026.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1477-1490, August 2026.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

The Backbone of Regionalisation: Refining Axial Regionalisation Through 3D Morphometric Sampling Strategies on Elapid Snakes

open access: yesJournal of Morphology, Volume 287, Issue 8, August 2026.
Using 3D geometric morphometrics on every precaudal vertebra from 12 elapid snakes, this study used segmented linear regression to test regionalisation. The results show a five‐region model is best supported, including short cervical and lumbar regions and a strong heart‐aligned boundary at approximately 20% of the pre‐caudal column.

AMOSTRAGEM DE ANFÍBIOS DE HÁBITOS FOSSORIAIS EM AMBIENTES ANTROPIZADOS [PDF]

open access: yes, 2021
Anfíbios de hábitos fossoriais são pouco amostrados devido à dificuldade de encontro dos indivíduos, justificada pelo comportamento críptico destes. Isto implica na dificuldade de proposição do status de conservação das espécies de hábitos fossoriais ...
