Vital fluorescent staining for non–destructive studies of neuromast topography in urodele amphibians

open access: yesActa Biologica Slovenica, 2018
Neuromasts are mechanosensory organs found in primarily aquatic vertebrates, including many species of amphibians, and are arranged as specific patterns to form the lateral-line system on the head and along the body.

Spatial distribution and seasonal movement patterns of reintroduced Chinese giant salamanders

open access: yesBMC Zoology, 2019
Background Very little is known about the temporal or spatial movement patterns of Chinese giant salamanders (Andrias davidianus) due to their rarity, remote habitat and secretive nature. Commercial breeding farms provide a unique opportunity as a source

Recent Advances in the Behavioral Ecology of European Plethodontid Salamanders

open access: yesAnimals, 2023
There is a recent growing interest in the study of evolutionary and behavioral ecology of amphibians. Among salamanders, Plethodontidae is the most speciose family, with more than 500 species, while in Europe, there are only 8 species, all belonging to ...

Risk of survival, establishment and spread of Batrachochytrium salamandrivorans (Bsal) in the EU

open access: yesEFSA Journal, 2018
Batrachochytrium salamandrivorans (Bsal) is an emerging fungal pathogen of salamanders. Despite limited surveillance, Bsal was detected in kept salamanders populations in Belgium, Germany, Spain, the Netherlands and the United Kingdom, and in wild ...

Cross-Life Stage Effects of Aquatic Larval Density and Terrestrial Moisture on Growth and Corticosterone in the Spotted Salamander

open access: yesDiversity, 2018
For organisms with complex life cycles, conditions experienced during early life stages may constrain later growth and survival. Conversely, compensatory mechanisms may attenuate negative effects from early life stages.

The Right Light: Tiger Salamander Capture Rates and Spectral Sensitivity

open access: yesWildlife Society Bulletin, 2020
Knowledge of population dynamics is critical for species of conservation concern so wildlife researchers need to take advantage of biases in animals' behaviors that could help them monitor populations.

Study of Natural Longlife Juvenility and Tissue Regeneration in Caudate Amphibians and Potential Application of Resulting Data in Biomedicine

open access: yesJournal of Developmental Biology, 2021
The review considers the molecular, cellular, organismal, and ontogenetic properties of Urodela that exhibit the highest regenerative abilities among tetrapods. The genome specifics and the expression of genes associated with cell plasticity are analyzed.

Heart regeneration in the salamander relies on macrophage-mediated control of fibroblast activation and the extracellular landscape

open access: yesnpj Regenerative Medicine, 2017
Macrophages necessary for heart regeneration Heart regeneration in salamanders is dependent on the activation of immune cells. James Godwin of The Jackson Laboratory and MDI Biological Laboratory in the US and colleagues depleted all major organs of a ...

Variation in Articular Cartilage Thickness Among Extant Salamanders and Implications for Limb Function in Stem Tetrapods

open access: yesFrontiers in Ecology and Evolution, 2021
The size and shape of articular cartilage in the limbs of extant vertebrates are highly variable, yet they are critical for understanding joint and limb function in an evolutionary context. For example, inferences about unpreserved articular cartilage in
