Close encounters of the three morphs: Does color affect aggression in a polymorphic lizard?

نویسندگان

چکیده

Color polymorphism is genetically controlled, and the process generating maintaining morphs can affect speciation/extinction rates. badges are useful signals in intraspecific communication because they convey information about alternative strategies potentially decrease unnecessary conflicts among different color morphs. Competition aggressive interactions contribute to maintenance. This could lead an uneven spatial distribution of a population local frequency each morph establishes intensity competition fitness male. We used polymorphic lizard, Podarcis muralis, assess if aggression varies under two contrasting hypotheses: heteromorphic versus homomorphic aggression. laboratory mirror tests after lizard manipulation, we verified consistency results with analysis wild population. Both experiments confirmed that more common during homomorphic than contests. The adoption behavioral minimize risks costs facilitate stable coexistence phenotypes reduce competition. A bias would advantage rarer morph, which suffer less harassment by obtaining advantage. be negatively-frequency-dependent stabilize polymorphism, possibly contributing sympatric speciation.

Morphology, performance, behavior and ecology of three color morphs in males of the lizard Podarcis melisellensis.

Males of a Croatian population of the lacertid lizard Podarcis melisellensis exhibit a striking polymorphism, with coloration of the throat and abdomen ranging from completely white, to yellow or orange. In a first attempt to explore the potential ecological and evolutionary significance of this polymorphism, we compared the three forms of males in aspects of their morphology, whole-animal perf...

Revealing the Biochemical and Genetic Basis of Color Variation in a Polymorphic Lizard.

Determining the mechanistic and genetic basis of animal coloration is essential to understand the costs and constraints on color production, and the evolution and maintenance of phenotypic variation. However, genes underlying structural color and widespread pigment classes apart from melanin remain largely uncharacterized, in part due to restricted taxonomic focus. We combined liquid chromatogr...
