The ubiquity of multiple signalling is a long-standing puzzle in the study of animal
communication: given the costs of producing and receiving signals, why use more than a …

The study of coloration in the polyphyletic reptilians has flourished in the last two decades, in
particular with respect to the underlying genetics of colour traits, the function of colours in …

The role of colours and colour patterns in behavioural ecology has been extensively studied
in a variety of contexts and taxa, while almost overlooked in many others. For decades …

Female preferences for specific male phenotypes have been documented across a wide
range of animal taxa, including numerous species where males contribute only gametes to …

Colour polymorphic species are model systems for examining the evolutionary processes
that generate and maintain discrete phenotypic variation in natural populations. Lizards …

Lizards have been model organisms for ecological and evolutionary studies from individual
to community levels at multiple spatial and temporal scales. Here we highlight lizards as …

In this contribution, the aspects of reptile and amphibian speciation that emerged from
research performed over the past decade are reviewed. First, this study assesses how …

Female mate choice is a dynamic process that allows individuals to selectively mate with
those of the opposite sex that display a preferred set of traits. Because in many species …

We describe discrete variation in throat color, an important sexual signal, in males of 2
populations of the mesquite lizard (Sceloporus grammicus). At one locality, males exhibit …

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