Studies on polymorphisms have been foundational to our understanding of evolution. The
presence of different phenotypic morphs is sometimes considered a precursor to speciation …

Colour variability is largely widespread in the animal world as it is tightly associated with
fitness and survivorship. Therefore, the drivers and implications of such variability have been …

Noble scallop Chlamys nobilis is an economically important edible marine bivalve that
display polymorphism in shells and flesh colors. The present study was carried out to …

Species color and color pattern vary geographically contributing to environmental tolerance
of the species to the fluctuating climate. In a constantly changing environment, the …

Sexual selection is one of the main processes involved in the emergence and maintenance
of heritable color polymorphisms in a variety of taxa. Here, we test whether the intensity of …

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 …

Lizards are ideal for studying colour polymorphism, because some species are polymorphic
and the morphs often have different ecological or reproductive strategies. We studied the …

Colour polymorphism occurs when two or more genetically-based colour morphs
permanently coexist within an interbreeding population. Colouration is usually associated to …

Highlights•The common wall lizard is a synantropic and colour polymorphic species.•We
investigated effects of habitat and colour morph on antipredator response.•Urbanization …

Identifying the processes that lead to the evolution and maintenance of links between colour
morphs and behavioural strategies has implications for the evolution of reproductive …
