TLDR
Review of data concerning 23 Anolis introductions indicates that the presence or absence of an ecologically similar native species may be an important determinant of colonization success or failure.Abstract:
Since its introduction ten years ago, Anolis sagrei has spread over much of Grand Cayman and is now more common in some habitats than the native anole, A. conspersus. Interspecific differences in body size, perch height, and microclimatic preference may have facilitated the colonization. Nonetheless, competition may be occurring between the species; comparisons with studies of habitat use prior to the arrival of A. sagrei indicate that in open habitats, where A. sagrei is now abundant, A. conspersus perches higher, but in closed habitats, where A. sagrei is absent, no change in perch height is evident. Review of data concerning 23 Anolis introductions indicates that the presence or absence of an ecologically similar native species may be an important determinant of colonization success or failure.read more

Competing for crevices: interspecific conflict influences retreat-site selection in montane lizards.

TL;DR: It is concluded that direct agonistic encounters between individuals of different species strongly influence habitat use by lizards within this assemblage of broadly sympatric species of viviparous montane skinks.

Ecology of a Cerrado Lizard Assemblage in the Jalapao Region of Brazil
TL;DR: It is suggested that under-representation of species in major clades (low taxon sampling) renders it difficult to detect potential historical and ecological effects on assemblage structure.

Adaptation, Speciation, and Convergence: A Hierarchical Analysis of Adaptive Radiation in Caribbean Anolis Lizards
TL;DR: The answer is that the classic model of ecological interactions as the driving force in adaptive radiation can account for this aspect of anole evolutionary diversity in the Caribbean anole radiations, but not entirely.

TL;DR: Observations indicate that asymmetric aggressive interactions between hatchlings of the study species reduce an important fitness component (i.e. growth rate) of P. melisellensis.

Habitat light, colour variation, and ultraviolet reflectance in the Grand Cayman anole, Anolis conspersus
TL;DR: Evidence is presented to show how geological, ecological, and physiological factors could have interacted to select for a short wavelength-reflective dewlap from a long wavelength- reflective precursor following the colonization of Grand Cayman from Jamaica by A. grahami between 2 and 3 Mya.

TL;DR: This is the revision of the classic text in the field, adding two new chapters and thoroughly updating all others as discussed by the authors, and the original structure is retained, and the book continues to serve as a combined text/reference.

The Anolis Lizards of Bimini: Resource Partitioning in a Complex Fauna
TL;DR: It is suggested that such small, non-dimorphic species are best suited for insinuation into complex faunas, whereas larger, dimorphic forms are best for the colonization of empty areas.

Ecology and evolution of Darwin's finches
TL;DR: This book is the classic account of how much the authors have since learned about the evolution of Darwin's Finches and shows how interspecific competition and natural selection act strongly enough on contemporary populations to produce observable and measurable evolutionary change.
