Terrestrial salamanders of the genus Salamandra represent one of the most prominent
groups of amphibians. They are mainly distributed across Europe but also reach Northern …

La historia biogeográfica de S. salamandra es bastante compleja. Los datos genéticos
analizados hasta la fecha apuntan a una colonización del centro y norte de Europa en el …

The use of image data to quantify, study and compare variation in the colours and patterns of
organisms requires the alignment of images to establish homology, followed by colour …

Aposematic bright colors have a key role for animal defense and can be expressed through
metabolic production or by acquiring pigments from diet. Aposematic coloration can be …

Abstract Theory predicts that, in organisms with complex life cycles, if the earlier‐stage
limiting factor induces weak later‐stage phenotypes, the development of the later‐stage trait …

The coexistence of multiple discrete color phenotypes (ie color polymorphism) has been
studied in many diurnal species where environmental light allows most visual systems to …

Sexual dichromatism in animals is usually associated with mating displays and is linked to
strong sexual selection. Among amphibians, it has mostly been reported in anurans and …

The study of morphological variation among and within taxa can shed light on the evolution
of phenotypic diversification. In the case of urodeles, the dorso‐ventral view of the head …

Experimental work in the early 20th century showed that background albedo experienced by
larvae of the fire salamander (Salamandra salamandra) induce a durable morphological …

Prey species signalling their toxicity to potential predators via conspicuous coloration occur
frequently in nature. This survival strategy, called aposematism, is thought to be successful …
