Color polymorphic sexual signals are often associated with alternative reproductive
behaviors within populations, and the number, frequency, or type of morphs present often …

Abstract Conservation breeding of West Indian rock iguanas (Cyclura) has met with limited
success historically. Many facilities witness high levels of aggression and mate …

A central assumption in evolutionary biology is that females of sexually dimorphic species
suffer costs when bearing male secondary sexual traits, such as ornamentation …

Highlights•We examined tactical adjustment of courtship signalling in male wolf
spiders.•Males varied in how much they modified courtship after experiencing female …

In species with biparental care and lifetime monogamy, the fecundity of a male's partner can
be a major component of his fitness but it is unclear whether males can assess female …

High male mating effort and high variation in female quality select for male mate choice,
which may be expressed as differential investment of reproductive effort based on female …

Chemical cues play an important role in sexual recognition in several lizard species. Here,
we investigated whether the neotropical lizard, Liolaemus pacha (Iguania: Liolaemidae) can …

Male courtship behavior and displays influence female mating decisions, and therefore
affect mating success in a diverse range of organisms. While there is substantial evidence …

When competing for mates, males of many species use cues from their rivals to evaluate
their chances of success. Signaling behavior is a vital component of male–male contests …

Little is known about the operation of male mate choice in systems with perceived high costs
to male choosiness. Scramble mating systems are one type of system in which male choice …
