Detection and succession properties of forested vernal pools with eDNA metabarcoding
Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.We examined the capacity of environmental DNA metabarcoding for studying biodiversity of forested vernal pools, using multiple assays to investigate different eukaryotic communities over space and time. Our results suggest that metabarcoding can serve as a complementary tool for ‘scaling up’ vernal pool biodiversity monitoring, illuminating ecological ...

Animals, 2022 The trophic niche of a species is one of the fundamental traits of species biology. The ideal trophic niche of a species is realized in the absence of interspecific competition, targeting the most profitable and easy-to-handle food resources.

Choosing the best of both worlds [PDF]
, 2011 The great crested newt (Triturus cristatus) is dependent on two environments for its survival: the aquatic habitat necessary for breeding and development, and the terrestrial habitat required for post-breeding and juvenile activities. For a population to

Description of a new species of crested newt, previously subsumed in Triturus ivanbureschi (Amphibia: Caudata: Salamandridae) [PDF]
, 2016 Multilocus molecular data play a pivotal role in diagnosing cryptic species (i.e. genetically distinct but morphologically similar species). A multilocus phylogeographic survey has provided compelling evidence that Triturus ivanbureschi sensu lato ...

Ecology and Evolution, Volume 16, Issue 1, January 2026.The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

Population Genetic Structure of the Endangered Kaiser's Mountain Newt, Neurergus kaiseri (Amphibia: Salamandridae). [PDF]
PLoS ONE, 2016 Species often exhibit different levels of genetic structuring correlated to their environment. However, understanding how environmental heterogeneity influences genetic variation is difficult because the effects of gene flow, drift and selection are ...

The reproductive dynamics of temperate amphibians: a review [PDF]
, 2007 The annual life cycle of pond breeding amphibians is characterized by periodical migrations between three critical habitats: breeding, post breeding - feeding - and hibernating.

An amphibian chemical defense phenotype is inducible across life history stages
Scientific Reports, 2017 Inducible phenotypic responses to environmental variation are ubiquitous across the tree of life, but it remains an open question whether amphibian chemical defense phenotypes are inducible.

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.ABSTRACT Reliable tools for the identification of genetic sex are invaluable in many fields of biology, but their design requires knowledge of sex‐linked sequences, which is lacking in many taxa. Restriction‐site‐associated DNA sequencing (RADseq) is widely used to identify sex‐linked markers, but multiple distinct strategies are employed, and it is ...

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...
