Hybridization and extensive mitochondrial introgression among fire salamanders in peninsular Italy

Scientific Reports, 2018
Discordance between mitochondrial and nuclear patterns of population genetic structure is providing key insights into the eco-evolutionary dynamics between and within species, and their assessment is highly relevant to biodiversity monitoring practices ...

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

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

Projecting the benefit of vericiguat in PARADIGM‐HF and DAPA‐HF populations: Insights from the VICTORIA trial

ESC Heart Failure, Volume 12, Issue 2, Page 1479-1484, April 2025.
Abstract Aims The VICTORIA trial demonstrated a significant reduction in the primary composite outcome of heart failure (HF) hospitalization or cardiovascular death with vericiguat relative to placebo in high‐risk HF. This study aimed to contextualize treatment effects of vericiguat in populations with varying risk profiles simulated from the PARADIGM ...

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

Integrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

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 ...

The commercial trade in exotic pets has had little impact on wild populations of reptiles and amphibians

Conservation Biology, EarlyView.
Abstract The commercial trade in exotic pets has raised concerns about population‐level impacts from collection in the wild; however, proponents of the trade claim that such concerns are unfounded. To resolve this debate, more information is needed on the volume of the pet trade, the species involved, their conservation status in the wild, and the ...

Microclimatic Growth Rates of Batrachochytrium salamandrivorans under Current and Future Climates: A Very High Spatial Resolution SDM for Bsal and Salamandra salamandra (Linnaeus, 1758) within Forest Habitats of the European Hotspot Area

Diversity
Chytridiomycosis is one of the greatest threats to the diversity of amphibians worldwide. Caused by the chytrid fungus Batrachochytrium salamandrivorans (Bsal), it plays a decisive role in species declines.

Trade network surveillance strategies

Ecosphere, Volume 17, Issue 11, November 2026.
Abstract The global success of the wildlife trade industry has led to the emergence of novel pathogens over the past two decades. The introduction of Batrachochytrium dendrobatidis to naive amphibian species has been a cause of global population decline and species extinction. A second chytridiomiycosis causing fungus, Batrachochytrium salamandrivorans

When One Matters More: Keystone Niche Individuals Shape Population‐Level Niches in Ectothermic Vertebrates

Journal of Zoology, Volume 330, Issue 2, Page 131-141, October 2026.
The recently proposed concept of Keystone Niche Individuals, that is, individuals that disproportionately influence their population's niche width, provides a framework to explore how individuals shape ecological niches. We applied this framework to a dataset of 482 salamanders across 21 populations and seven taxa to assess the prevalence and ...
