This article is part of a Special Issue “Chemosignals and Reproduction”. Many lizards have
diverse glands that produce chemosignals used in intraspecific communication and that can …

Pheromones have been defined, based on entomological studies, as chemicals or
semiochemicals produced by one individual that effect a change in the physiology …

Many lizard and amphisbaenian lineages possess follicular glands in the dermis of the inner
thighs and/or the area anterior to the cloaca. These tubular glands produce a holocrine …

Animals communicate via a variety of sensory channels and signals. Studies on acoustic
and visual communication systems suggest that differences in the physical environment …

The evolution of chemical signals is subject to environmental constraints. A multicomponent
signal may combine semiochemical molecules with supporting compounds able to enhance …

The signals that animals use to communicate often differ considerably among species. Part
of this variation in signal design may derive from differential natural selection on signal …

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

Lizards communicate with others via chemical signals, the composition of which may vary
among species. Although the selective pressures and constraints affecting chemical signal …

Femoral glands of male lizards produce waxy secretions that are involved in inter-and
intraspecific chemical communication. The main components of these secretions are …

Widespread species often show extensive phenotypic variation due to the contrasting abiotic
and biotic factors that shape selective pressures in different environments. In this context, the …
