A pattern-based tool for long-term, large-sample capture-mark-recapture studies of fire salamanders Salamandra species (Amphibia: Urodela: Salamandridae)

open access: yesActa Herpetologica, 2017
Solid population studies depend on reliable capture-mark-recapture (CMR) methodology. The available methods for such studies on amphibians are often invasive, unsuitable for long-term studies, time-consuming and/or expensive.

Environmental DNA (eDNA) and Field Surveys as Complementary Tools for the Biomonitoring of Amphibian Communities

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Amphibians are facing large population declines as a result of both natural and anthropogenic threats. Reconstructing and understanding the composition and structure of amphibian communities is essential for developing effective monitoring and conservation strategies.

Genetic drift and rapid evolution of viviparity in insular fire salamanders (Salamandra salamandra) [PDF]

open access: yesHeredity, 2011
Continental islands offer an excellent opportunity to investigate adaptive processes and to time microevolutionary changes that precede macroevolutionary events. We performed a population genetic study of the fire salamander (Salamandra salamandra), a species that displays unique intraspecific diversity of reproductive strategies, to address 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

open access: yesDiversity
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.

Fast Inference of Interactions in Assemblies of Stochastic Integrate-and-Fire Neurons from Spike Recordings [PDF]

open access: yes, 2011
We present two Bayesian procedures to infer the interactions and external currents in an assembly of stochastic integrate-and-fire neurons from the recording of their spiking activity.

Counting solutions from finite samplings

open access: yes, 2012
We formulate the solution counting problem within the framework of inverse Ising problem and use fast belief propagation equations to estimate the entropy whose value provides an estimate on the true one.

The Source of Melanocytes in Ortho- and Heterotopic Tail Regenerates of Axolotls and the Dependence of the Regenerative Response on the Presence of Neural Tissue

open access: yesAnatomia
We studied the regeneration of orthotopic and heterotopic tails in larval axolotls. First, we analyzed tail regeneration following reciprocal exchange of cuffs of tail integument between dark-colored (wild-type) and yellow-colored (hybrid) larval animals.

Identifying climate‐change refugia for species management and conservation in the Pacific Northwest

open access: yesConservation Science and Practice, Volume 8, Issue 1, January 2026.
Abstract The impacts of climate change are already affecting many species and habitats, presenting challenges for species management and conservation. Protecting climate refugia—areas buffered from climate shifts where species can persist despite broader changes—has been proposed as a tool for managing species under climate change.

The effect of brumation on memory retention [PDF]

open access: yes, 2017
Long-term torpor is an adaptive strategy that allows animals to survive harsh winter conditions. However, the impact that prolonged torpor has on cognitive function is poorly understood.
