The plethora of studies devoted to the topics of male competition and female mate choice
belie the fact that their interaction remains poorly understood. Indeed, on the question of …

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 …

Sex determination, due to the obvious association with reproduction and Darwinian fitness,
has been traditionally assumed to be a relatively conserved trait. However, research on …

The important role that mate choice plays in the lives of animals is matched by the large and
active research field dedicated to studying it. Researchers work on a wide range of species …

In sharp contrast with mammals and birds, many cold-blooded vertebrates present
homomorphic sex chromosomes. Empirical evidence supports a role for frequent turnovers …

Space is a limited resource in which many animals need to perform basic functions such as
feeding and reproducing. Competition over access to space can induce a variety of …

Within species, color morphs may enhance camouflage, improve communication and/or
confer reproductive advantage. However, in the male cichlid Astatotilapia burtoni, body color …

Mate choice has important evolutionary consequences because it influences assortative
mating and the level of genetic variation maintained within populations. In species with …

Selection favours females that attend to reliable information about male health or genetic
quality. Male nutritional state can be an important indicator of mate quality since poor …

Species recognition can often play a key role in female mating preferences. Far less is
known about conspecific mate recognition from the male perspective. In many closely …
