Abstract Since its introduction, Anolis sagrei (Sauria: Polychrotidae) has been replacing native A. carolinensis in Florida and native A. conspersus in Grand Cayman Island as the common anole of urban environments and other open habitats. To assess the likelihood that predation of juvenile native anoles by A. sagrei adults is an important interaction in this process, the propensities for intraguild predation and cannibalism were assessed for A. sagrei and A. carolinensis in Florida and for A… Expand

The distribution of non-native Anolis lizards on Saint Lucia, Lesser Antilles
Abstract. Anolis lizards are common throughout the islands of the West Indies, often with several species existing in sympatry by demonstrating conspicuous niche separation. With increasingExpand
Ontogenetic habitat shift and risk of cannibalism in the common chameleon (Chamaeleo chamaeleon)
TLDR
The field experiments showed that juveniles actively avoid the presence of adults by concealment or flight and the risk of cannibalism towards juveniles is an important selective force behind the ontogenetic habitat shift observed in the common chameleon. Expand
Invasive Anolis sagrei on St. Vincent and Its Potential Impact on Perch Heights of Anolis trinitatis
TLDR
Investigation of the distribution of introduced populations and evaluated possible effects on perch heights of native anoles at a site where all three species occur found little evidence that A. sagrei has affected either native species. Expand
Behavioural mechanisms of invasion and displacement in Pacific island geckos (Hemidactylus)
TLDR
Evidence of interspecific courtship suggests that sexual interference may be a more likely mechanism of displacement in the displacement of the house gecko H. garnotii, but further study is required to determine whether interspecific mating disrupts parthenogenetic reproduction. Expand
Niche Relationships and Interspecific Interactions in Antiguan Lizard Communities
TLDR
Results suggest interspecific interactions, most likely due to competition and intraguild predation, are important for structuring Antiguan lizard communities. Expand
Emergent impacts of cannibalism and size refuges in prey on intraguild predation systems
TLDR
The results indicate that cannibalism and ontogenetic niche shifts can result in behavior-mediated indirect interactions that reduce the impact of the predator on the mortality of its prey and alter the interactions of IGP systems, but also indicate that size is not the sole determinant and that the authors also need to account for the species identity when predicting the dynamics of communities. Expand
Food webs and intraguild predation: community interactions of a native mesocarnivore.
TLDR
The results support the prediction that, under intraguild predation in terrestrial systems, top predator distribution matches resource availability (resource match), while intermediate predator distribution inversely matches predation risk (safety match). Expand
Boldness underlies foraging success of invasive Lepidodactylus lugubris geckos in the human landscape
TLDR
Part of the advantage A-clones have in structurally simple human landscapes stems from their innate boldness, which increases their ability to exploit limited food resources in the structurally complex habitat. Expand
POPULATION DENSITY AND OVER-WINTERING OF AN EXOTIC LIZARD, THE BROWN ANOLE ANOLIS SAGREI, AND AN EVALUATION OF ANOLE DISTRIBUTION IN LAFOURCHE AND TERREBONNE PARISHES, LOUISIANA
The brown anole Anolis sagrei, native to parts of the Caribbean, was introduced into the United States in the Florida Keys in the late 1800’s and subsequently became established. Since that time, theExpand
ASYMMETRY IN MUTUAL PREDATION BETWEEN THE ENDANGERED JAPANESE NATIVE CRAYFISH CAMBAROIDES JAPONICUS AND THE NORTH AMERICAN INVASIVE CRAYFISH PACIFASTACUS LENIUSCULUS: A POSSIBLE REASON FOR SPECIES REPLACEMENT
TLDR
It is suggested that asymmetry in mutual predation can be an important cause of species replacement of the native C. japonicus by the invasive P. leniusculus in the field. Expand

Behaviour of the suspected lizard competitors Anolis sagrei and Anolis carolinensis: an experimental test for behavioural interference
TLDR
In staged encounters between males and females, courtship behaviour was usually observed only in conspecific encounters, and copulation was observed exclusively in conspecified encounters, suggesting that copulation between these species is uncommon under natural conditions. Expand

One group of lizards-the iguanid genus Anolis in the West Indies-is now sufficiently well known to permit an empirical test of ecological theories of colonization in terms of these relatively slowlyExpand
Presence and Absence of Habitat Shift in Some Widespread Lizard Species
TLDR
Results imply that animals similar to widespread forms in some niche dimension other than structural habitat are those most likely to cause shift in structural habitat and suggest existence of a competition function with respect to size. Expand
Intra- and interspecific interference behaviour among sexual and asexual geckos
TLDR
Investigation of the level of inter- and intraspecific aggression between three species of gekkonid lizards found males were more likely to approach and bite an asexual female and less likely to be spatially displaced by the approach of an a sexual female than vice versa, suggesting that competitive exclusion is at least partially caused by behavioural interactions.

Spatial and breeding relationships of the lizard, Anolis carolinensis : Evidence of intrasexual selection
TLDR
A polygynous mating system in which females seem to fit a 'no cost, neutral-mate-choice' model, and males (in response to sedentary, contiguously distributed females who clutch at weekly intervals over a 4-month period) employ territorial contests within an endurance rivalry as a prime mechanism for mate assortment is documented.

THE ECOLOGY AND EVOLUTION OF INTRAGUILD PREDATION: Potential Competitors That Eat Each Other
TLDR
The purpose is to document the ubiquity and importance of intraguild predation and to establish a theoretical framework for its analysis, which is the first synthesis of IGP into a general work. Expand
Species Packing in Desmognathus Salamanders: Experimental Demonstration of Predation and Competition
TLDR
The hypothesis that predation is the important organizing force of Desmognathus salamanders is largely supported, with a small but statistically significant increase in the numbers of D. monticola and D. quadramaculatus, a result that confirmed the existence of competition. Expand
Diet Composition in Postmetamorphic Bullfrogs and Green Frogs: Implications for Interspecific Predation and Competition
TLDR
Diet composition of postmetamorphic bullfrogs and green frogs co-occurring at two study sites in southwest Michigan suggests the opportunity for substantial competition between these species is probably small, and is restricted to individuals of similar body size. Expand
Territoriality and the defence of predator-refuges in juvenile lizards
TLDR
Results indicate that defence of predator-safe home-sites is probably an important function of juvenile A. aeneus territoriality. Expand
The Ecological Significance of Sexual Dimorphism in Size in the Lizard Anolis conspersus
TLDR
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. Expand
