Journal ArticleDOI
An Experimental Demonstration of the Species-Recognition Role of Anolis Dewlap Color
TL;DR: The Cuatro Cienegas fishes: research review and a local test of diversity versus habitat size and the function of gonopodial parts and b havioral pattern during copulation by Gambusia (Poeciliidae) are reviewed.
Journal ArticleDOI
Evolution of Anolis Lizard Dewlap Diversity
TL;DR: It is found that dewlap configurations exhibit substantial diversity, but that most are easily categorized into six patterns that incorporate one to three of 13 recognizable colors, which provides only weak support for the Species Recognition hypothesis.
Journal ArticleDOI
Testing the hypothesis that a clade has adaptively radiated: iguanid lizard clades as a case study.
TL;DR: It is argued that the term “adaptive radiation” should be reserved for those clades that are exceptionally diverse in terms of the range of habitats occupied and attendant morphological adaptations; and a test, focusing on disparity in the ecological morphology of monophyletic groups within the lizard family Iguanidae, is proposed.
Journal ArticleDOI
Rapid temporal reversal in predator-driven natural selection.
TL;DR: Experimental studies on 12 islets confirmed predictions that the introduction of a terrestrial predator would first select for longer-legged lizards, but as the lizards shifted onto high twigs to avoid the predator, selection would reverse toward favoring the shorter-legged individuals better able to locomote there.
Journal ArticleDOI
Testing the island effect in adaptive radiation: rates and patterns of morphological diversification in Caribbean and mainland Anolis lizards
TL;DR: Comparisons of patterns and rates of morphological evolution found that rates and extent of diversification were comparable, but Anolis adaptive radiation is not an island phenomenon; in independent colonizations of both island and mainland habitats, island anoles have evolved shorter limbs and better-developed toe pads.
