The threat posed by invasive non-native species worldwide requires a global approach to
identify which introduced species are likely to pose an elevated risk of impact to native species …

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors.
These conspicuous colors serve a diversity of signaling functions, but their molecular basis …

Photographic identification is a promising marking technique alternative to the toe-clipping,
since it is completely harmless, cheap, and it allows long time identification of individuals. Its …

The ability to estimate quantity, which is crucially important in several aspects of animal
behaviour (eg foraging), has been extensively investigated in most taxa, with the exception of …

Colour polymorphism (CP) is widespread in animals, but mechanisms underlying morph
evolution and maintenance are not completely resolved. In reptiles, CP is often genetically …

Intra-specific colour variation may either reflect a discrete polymorphism, potentially related
to life-history strategies; a continuous signal, which may be related to individual quality; or a …

Microplastics (MPs) have been reported to threaten a wide variety of terrestrial, marine, and
freshwater organisms. However, knowledge about the effects of MPs on anuran amphibians, …

Previous studies showed that common wall lizards (Podarcis muralis) are polymorphic in
colour, both sexes showing three main ventral morphs (white, yellow and red) within the same …

Nowadays, the loss of biodiversity in agroecosystems due to the intensification of farming
practices is happening very fast, and therefore, stopping or slowing it down should be a priority …

In polymorphic species of animals, colour morphs may show alternative physiological
properties, and hence evolve or be maintained as an indirect response to selection exerted on …
