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

The global decline of reptiles, deja’ vu amphibians

TL;DR: Public attitudes about the need for conservation of reptiles are probably linked to concern about amphibian declines and deformities, and counts of “officially” recognized endangered and threatened species are likely to grossly underestimate the actual number of imperiled s pecies.

Genetic variation increases during biological invasion by a Cuban lizard

TL;DR: It is shown that one key to invasion success may be the occurrence of multiple introductions that transform among- population variation in native ranges to within-population variation in introduced areas.

TL;DR: Character displacement research in the past two decades provides sound statistical support for the hypothesis in a wide variety of taxa, albeit with a phylogenetically skewed representation.

Invasion resistance arises in strongly interacting species-rich model competition communities
TL;DR: A logical framework for an island-biogeographic theory in which species turnover is low even in the face of persistent invasions and for the protection of fragile native species from invading exotics is provided.

The Ecological Significance of Sexual Dimorphism in Size in the Lizard Anolis conspersus.
TL;DR: Anolis conspersus selects prey from a wide range of taxa and shows no obvious intraspecific specialization not connected to differences in microhabitat and prey size.

TL;DR: The history of faunas, whether studied by paleontologists and zoogeographers or by systematists, has customarily been described in terms of phylogeny or colonization—in terms of origin or arrival of species.
