Article Abstract
Amphibians globally suffer from emerging infectious diseases like chytridiomycosis caused by the continuously spreading chytrid fungi. One is Batrachochytrium salamandrivorans (Bsal) and its disease ‒ the 'salamander plague' ‒ which is lethal to several caudate taxa. Recently introduced into Western Europe, long distance dispersal of Bsal, likely through human mediation, has been reported. Herein we study if Alpine salamanders (Salamandra atra and S. lanzai) are yet affected by the salamander plague in the wild. Members of the genus Salamandra are highly susceptible to Bsal leading to the lethal disease. Moreover, ecological modelling has shown that the Alps and Dinarides, where Alpine salamanders occur, are generally suitable for Bsal. We analysed skin swabs of 818 individuals of Alpine salamanders and syntopic amphibians at 40 sites between 2017 to 2022. Further, we compiled those with published data from 319 individuals from 13 sites concluding that Bsal infections were not detected. Our results suggest that the salamander plague so far is absent from the geographic ranges of Alpine salamanders. That means that there is still a chance to timely implement surveillance strategies. Among others, we recommend prevention measures, citizen science approaches, and ex situ conservation breeding of endemic salamandrid lineages.

Taiwan harbors five endemic species of salamanders (Hynobius spp.) that inhabit distinct alpine regions, contributing to population fragmentation across isolated "sky islands". With an evolutionary history spanning multiple glacial-interglacial cycles, these species represent an exceptional paradigm for exploring biogeography and speciation.

The ongoing biodiversity crisis is strongly threatening amphibians, mostly because of their peculiar physiology, their sensitivity to climate change and the spread of diseases. Effective monitoring involving assessments of pressure effects across time and estimation of population trends play a key role in mitigating amphibian decline. To improve implementation of standardized protocols and conservation efforts, we present here a dataset related to one of the amphibian genera whose onservation status is considered the most declining according to the IUCN.

Article Synopsis
- Amphibians worldwide are threatened by diseases like chytridiomycosis, especially from the chytrid fungus Batrachochytrium salamandrivorans (Bsal), which causes the deadly 'salamander plague.'
- This study investigates whether Alpine salamanders (Salamandra atra and S. lanzai) are affected by Bsal, given that they are known to be highly susceptible to this pathogen.
- The analysis of over 1,100 salamanders in the Alps revealed no Bsal infections, indicating that the salamander plague has not yet reached this area, but suggests the need for proactive conservation measures to prevent future outbreaks.

Terrestrial ectotherms react to acute changes in environmental temperatures by adjusting their behaviour. Evaluating the adaptive potential of these behavioural adjustments requires information on their repeatability and plasticity. We examined behavioural response (exploration) to acute temperature change in two amphibian taxa, alpine (Ichthyosaura alpestris) and smooth (Lissotriton vulgaris) newts.

Article Synopsis
- Amphibians play a key role in nutrient cycling in ecosystems, making their dietary habits essential for conservation efforts.
- A study conducted in northern Italy focused on the trophic ecology of the rare Golden Alpine salamander, revealing its generalist feeding strategy and specific prey preferences.
- The research highlighted significant individual diet variation, suggesting a complex understanding of this species' feeding behaviors and their ecological roles.
