Anatomical network analysis of the musculoskeletal system reveals integration loss and parcellation boost during the fins-to-limbs transition [PDF]

open access: yes, 2018
Tetrapods evolved from within the lobe-finned fishes around 370 Ma. The evolution of limbs from lobe-fins entailed a major re-organization of the skeletal and muscular anatomy of appendages in early tetrapods. Concurrently, a degree of similarity between

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

Evidence of tail autotomy in the European plethodontid Hydromantes (Atylodes) genei (Temmick and Schlegel, 1838) (Amphibia: Urodela: Plethodontidae) [PDF]

open access: yes, 2010
7 páginas, 1 figura.Caudal autotomy is a defensive mechanism widely adopted by lungless salamanders (Plethodontidae) from the New World. In contrast, in Europe, this mechanism was not described until very recently for just one Sardinian species ...

A Multi‐Modelling Approach for Informing the Conservation of a Cold‐Adapted Terrestrial Amphibian in the Face of Climate Change

open access: yesJournal of Biogeography, Volume 51, Issue 12, Page 2469-2483, December 2024.
ABSTRACT Aim We aimed to assess potential climate change impacts on the distribution of a cold‐adapted terrestrial amphibian that shows strong intraspecific differentiation. Location Alps and Dinarides. Taxon Alpine salamander (Salamandra atra). Methods We built SDMs for each of two major intraspecific lineages (S. a.

Optimising recovery of DNA from minimally invasive sampling methods: Efficacy of buccal swabs, preservation strategy and DNA extraction approaches for amphibian studies

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
In this multiple‐case study, we tested a comprehensive set of factors impacting DNA recovery from buccal swabs, including the type of swab, storage type and conditions and DNA extraction method. Based on our results, we are able to propose recommendations for improved DNA recovery, taking into consideration budget and field condition constraints ...
