Amphibians of the Simbruini Mountains (Latium, Central Italy)

open access: yesActa Herpetologica, 2010
Little attention has been paid to the herpetological fauna of the Simbruini Mountains Regional Park, Latium (Central Italy). In this study, we surveyed 50 sites in the course of about ten years of field research, especially during the period 2005-2008 ...

Five Hidden Species in a Widespread European Vertebrate: Disentangling the Alpine Newt Cryptic Species Complex Through Genomic Phylogeography. [PDF]

open access: yesMol Ecol
ABSTRACT Through genomic phylogeography, previously unrecognised biodiversity can be revealed. The alpine newt serves as a case in point: this taxon carries highly distinct mtDNA clades and has a severely fragmented range. We obtain genome‐wide data with target enrichment by sequence capture to delineate cryptic species and disentangle their ...

Static analysis and parameters synthesis of planetary-layshaft transmissions with three power flows

open access: yesMATEC Web of Conferences, 2018
The increase in the number of transmission ratios in the vehicles gearboxes leads to an increase in the number of mechanisms used and their complication. One way to obtain simple designs of multi-speed transmissions with smaller number of gears, clutches,

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]

open access: yes, 2015
Amphibian declines and extinctions are emblematic for the current sixth mass extinction event. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans ...

Notes on Salamandra Salamandra ssp. [PDF]

open access: yesBijdragen tot de Dierkunde, 1968
On 22-VII-1960 I caught some specimens of Salamandra salamandra fastuosa Schreiber between Lago Ercina and Lago Enol, ± 1000 m above Covadonga (Picos de Europa, Cantabrian Mountains, Spain). On 14-VIII-1961 from one of the salamanders two young were born (length 40 and 45 mm).

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

Acoustic enrichment in wildlife passages under railways improves their use by amphibians

open access: yesGlobal Ecology and Conservation, 2020
Linear transport infrastructure can impact wildlife directly or indirectly, and amphibians are particularly affected. In some cases, mitigation measures – such as tunnels below the linear transport infrastructure – are implemented, but an evaluation of ...

Landscape resistance constrains hybridization across contact zones in a reproductively and morphologically polymorphic salamander

open access: yesScientific Reports, 2021
Explicitly accounting for phenotypic differentiation together with environmental heterogeneity is crucial to understand the evolutionary dynamics in hybrid zones.

Habitat adaptation rather than genetic distance correlates with female preference in fire salamanders () [PDF]

open access: yes, 2009
Background: Although some mechanisms of habitat adaptation of conspecific populations have been recently elucidated, the evolution of female preference has rarely been addressed as a force driving habitat adaptation in natural settings.
