Post-epizootic salamander persistence in a disease-free refugium suggests poor dispersal ability of Batrachochytrium salamandrivorans [PDF]
, 2018 Lack of disease spill-over between adjacent populations has been associated with habitat fragmentation and the absence of population connectivity. We here present a case which describes the absence of the spill-over of the chytrid fungus Batrachochytrium

Ecography, Volume 2026, Issue 5, May 2026.Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Human-caused climate change in United States national parks and solutions for the future [PDF]
, 2020 Human-caused climate change has exposed the US national park area to more severe increases in heat and aridity than the country as a whole and caused widespread impacts on ecosystems and resources.

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Acta Herpetologica, 2014 Alternative reproductive strategies are widespread in caudate amphibians. Among them, fire salamanders (Salamandra salamandra) usually rely on streams to give birth to aquatic larvae but also use ponds, whereas palmate newt larvae (Lissotriton helveticus)

Contributions to the functional morphology of caudate skulls: kinetic and akinetic forms [PDF]
PeerJ, 2016 A strongly ossified and rigid skull roof, which prevents parietal kinesis, has been reported for the adults of all amphibian clades. Our μ-CT investigations revealed that the Buresch’s newt (Triturus ivanbureschi) possess a peculiar cranial construction.

Inferring Time‐to‐Speciation From Hybrid Zone Analysis Informs Assessments of Taxonomic Inflation
Molecular Ecology, Volume 35, Issue 9, May 2026.ABSTRACT Measuring gene flow across hybrid zones can provide a direct evaluation of reproductive isolation (RI) between evolutionary divergent lineages. Geographic‐explicit modelling of gene flow across hybrid zones, known as cline analysis, thus offers a gold standard for species delimitation under the biological species criterion.

, 2023 The trophic niche is one of the most important ecological traits for any species, as it provides information about trophic position in a food web, preference on foraging sites, intra- and interspecific interactions. In this study we examined seasonal variations in the diet composition of two sympatric salamanders from central Italy, the Italian cave ...

Larval monitoring of fire salamanders within a Sparkling Science Project [PDF]
eco.mont (Journal on Protected Mountain Areas Research), 2012 The mixed forest of the locally protected Aigner Park in the city of Salzburg, Austria, is a good example of a perfect fire salamander habitat. It provides ideal habitat conditions for the aquatic and terrestrial life of this threatened amphibian species.

Ecology and Evolution, Volume 16, Issue 4, April 2026.We repeatedly tested 158 individual long‐tailed finches, Poephila acuticauda, of two different sub‐species and their hybrids for differences in their flight performances. Several flight performance variables were repeatable across individuals. Contrary to expectations, P. a. hecki individuals did not display superior flight performance to P.
