Sex-specific morphs exhibit discrete phenotypes, often including many disparate traits, that
are observed in only one sex. These morphs have evolved independently in many different …

Colour polymorphisms (CP's) continue to be of interest to evolutionary biologists because of
their general tractability, importance in studies of selection and potential role in speciation …

The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Loss of recombination between sex chromosomes often depletes Y chromosomes of
functional content and genetic variation, which might limit their potential to generate …

This study is the first investigation on seasonal dynamics of parasites component community
of the Aequidens tetramerus from an Amazon River tributary, in Northern Brazil. A total of …

Variation in color morph behavior is an important factor in the maintenance of color
polymorphism. Alternative anti-predator behaviors are often associated with morphological …

Remarkable diversity in behaviour and morphology (phenotypes) are often observed within
a species; this diversity can be understood in terms of individuals maximizing their fitness …

Male alternative reproductive strategies are found in some species of most major animal
taxa but are especially widespread in fishes. Mature males of the shortfin molly, Poecilia …

Sexual selection is a driver of morphological and behavioral diversity. It may also play a role
in the maintenance of behavioral and morphological polymorphisms. Adaptive theory …

Highlights•In red devil cichlid fish, individuals are either 'dark'or 'gold'in colour.•We assessed
behaviour of these two colour morphs in different environments.•'Dark'fish explored more in …
