Transposable elements (TEs) are selfish genetic elements that mobilize in genomes via
transposition or retrotransposition and often make up large fractions of vertebrate genomes …

Freeze tolerance is an amazing winter survival strategy used by various amphibians and
reptiles living in seasonally cold environments. These animals may spend weeks or months …

Salamanders serve as important tetrapod models for developmental, regeneration and
evolutionary studies. An extensive molecular toolkit makes the Mexican axolotl (Ambystoma …

The canonical model of sex-chromosome evolution predicts that, as recombination is
suppressed along sex chromosomes, gametologs will progressively differentiate, eventually …

Genetic studies of rare and endangered species often focus on defining and preserving
genetically distinct populations, especially those having unique adaptations [1, 2]. Much less …

The discovery and delimitation of species has changed dramatically over time. Species
delimitation practices became more thorough and formal in the 1900s with the introduction …

Animal personality and behavioral syndromes can have profound effects on individual
fitness. Consequently, there is growing recognition that knowledge of these phenomena …

The relationship between genome size and the percentage of transposons in 161 animal
species evidenced that variations in genome size are linked to the amplification or the …

Frogs play important ecological roles, and several species are important model organisms
for scientific research. The globally distributed Ranidae (true frogs) are the largest frog …

Several previous genomic studies have focused on adaptation to high elevations, but these
investigations have been largely limited to endotherms. Snakes of the genus Thermophis …
