Urodele amphibians (∼ 768 spp.), salamanders and newts, are a rich source of molecules
with bioactive properties, especially those isolated from their skin secretions. These include …

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 …

Amphibians are a rich source of biologically active molecules, but the majority of Toxinology
scientific articles devoted themselves to investigating the anurans, given its worldwide …

The combined use of noxious chemical defences and conspicuous warning colours is a
ubiquitous anti-predator strategy. That such signals advertise the presence of defences is …

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 …

Coloration has been associated with multiple biologically relevant traits that drive adaptation
and diversification in many taxa. However, despite the great diversity of colour patterns …

Warning colouration reduces predation risk by signalling or mimicking the unpleasantness
of prey and therefore increases survival. We tested in two experiments the evolutionary costs …

Computer-aided individual recognition of animals based on their natural markings has
become an indispensable tool in ecology research. However, this is problematic in species …

Aposematism is a visual communication system in which bright and contrasted coloured
prey warn predators about their unprofitability. The Northern Spectacled Salamander …

The genus Salamandra encompasses six species with marked color pattern variations
(yellow spots on black or primarily black or yellow) and reproductive strategies (viviparous …
