Subterranean systems provide a suitable overwintering habitat for Salamandra salamandra

International Journal of Speleology, 2017
The fire salamander (Salamandra salamandra) has been repeatedly noted to occur in natural and artificial subterranean systems. Despite the obvious connection of this species with underground shelters, their level of dependence and importance to the ...

Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander [PDF]

Ecol Evol
We examined clinal gradients in reproductive modes and associated offspring body condition across a hybrid zone between two bimodal viviparous subspecies of Salamandra salamandra. We found a clear cline in reproductive modes, with pure modes at the extremes and mixed modes in central populations.

Factors determining the dorsal coloration pattern of aposematic salamanders

Scientific Reports, 2022
Aposematic bright colors have a key role for animal defense and can be expressed through metabolic production or by acquiring pigments from diet. Aposematic coloration can be related to both local adaptations and availability of trophic resources.

Blue plaque review series: Thomas Graham Brown: Before his time

Experimental Physiology, EarlyView.
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

Spatiotemporal reproductive strategies in the fire salamander: a model and empirical test [PDF]

Behavioral Ecology, 2011
Although density-dependent processes and the risk of pool desiccation dominate temporary pool ecology literature, the spreading of larvae across pools and time as a strategy for managing these central stress factors has not been rigorously addressed as an adaptive mechanism.

Synthesis of knowledge on the effects of fire and fire surrogates on wildlife in US dry forests [PDF]

, 2009
Summary: Dry forests throughout the United States are fire-dependent ecosystems, and much attention has been given to restoring their ecological function.

Weak pairwise correlations imply strongly correlated network states in a neural population [PDF]

, 2005
Biological networks have so many possible states that exhaustive sampling is impossible. Successful analysis thus depends on simplifying hypotheses, but experiments on many systems hint that complicated, higher order interactions among large groups of ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

À propos des dénominations de la salamandre d’Afrique du Nord : motivations, contact de langues et approche ethnobiologique

Géolinguistique, 2021
Salamandra algira is the only African salamander species. This amphibian can only be found in a few mountain ranges of Algeria and Morocco. We collected one hundred salamander denominations among the Berber and Arabic varieties practice in these moutains.
