The field of anole ecomorphology was born 50 years ago this month when Bruce Collette published his pathbreaking paper, “Correlations between ecology and morphology in anoline lizards from Havana, Cuba and southern Florida” in the Bulletin of the Museum of Comparative Zoology. It was this paper that first explicitly detailed the relationship between morphology and habitat use in Anolis lizards and this was the start of the research program of Rand, Williams, Schoener and others that today has made Anolis a textbook case of ecomorphological diversification. Indeed, because the term “ecomorph” itself can be traced to Ernest Williams’ classic 1972 paper (see p.56 of Lizards in an Evolutionary Tree), in many respects, this month represents an important landmark in the development of the field of ecological morphology.

            So, what did the paper say? The summary says it all: “This paper has attempted to correlate ecology with morphology in six species of Anolis from southern Florida and Havana, Cuba. It is felt that with proper ecological data, valid correlations can be made that can lead to an appreciation of the significance of characters often used in taxonomic analysis. Also, light is shed upon the structural adaptations that allow related sympatric species to occupy the same geographical area without facing deleterious competition. It has been shown that selection has acted so that lizards will usually match the color of their natural background. Examples have been shown to support the idea that peritoneal pigmentation is connected with exposure to radiation. The value of long legs to terrestrial lizards has been shown. Short relative tail length has been correlated with arboreality. The more arboreal members of a group of sympatric species have been shown to be larger and have more lamellae than terrestrial species. Data have been presented to support the contention that increased numbers of lamellae are an adaptation to increased arboreality.”
