Display behaviour and dewlap colour as predictors of contest success in brown anoles

摘要: Many animals display visual signals in male contests for access to females and territories. These can be multimodal stimulate different aspects of a signal receiver’s system. Over two summers, we tested whether behaviour dewlap colour might function as that predict contest success when males compete either mates or territories brown anole lizards. We found (PC1, correlated composite head-bob, push-up, extension frequency) an aspect (PC3, the relative amounts ultraviolet, yellow, orange, red margin) were retained minimum adequate model predicting across years social contexts. Winners showed significant differences (winners displayed more) margin PC3 had lower scores) compared losers. findings suggest serve indicating male’s ability win © 2014 The Linnean Society London, Biological Journal Society, 2014, 111, 646–655.
