Twenty‐seven islands in the Lesser Antilles contain either one or two species of Anolis lizards. On nine of the ten two‐species islands, the species differ substantially in size; 16 of the 17 one‐species islands harbor an intermediate‐sized species. Two processes could produce such a pattern: size adjustment (or character displacement), in which similar‐sized species evolve in different directions in sympatry; and size assortment, in which only different‐sized species can successfully colonize…

Character displacement in some Cnemidophorus lizards revisited: a phylogenetic analysis.
TLDR
A phylogeny using nucleotide sequences of the cytochrome b gene is constructed to infer the evolutionary history of body size change and historical patterns of colonization in the Cnemidophorus system, revealing potential cryptic species within mainland populations of C. tigris.
ADAPTATION AND CONSTRAINT IN THE EVOLUTION OF SPECIALIZATION OF BAHAMIAN ANOLIS LIZARDS
Interspecific interactions affect habitat use and subsequent morphological adaptation in Anolis lizards. We examined populations of two species of Anolis lizards that evolved in the species‐rich…
THE PARADOX OF THE PHYLOGENY: CHARACTER DISPLACEMENT OF ANALYSES OF BODY SIZE IN ISLAND ANOLIS
TLDR
A new analysis of body‐size evolution in Anolis lizards of the Lesser Antilles Anolis supported the taxon‐cycle hypothesis but nevertheless failed to reject the character‐displacement hypothesis.
A phylogenetic analysis of body size evolution in the Anolis roquet group (Sauria: Iguanidae): character displacement or size assortment?
TLDR
It is concluded that patterns of body size differences in the A. roquet species group appear to be the result of a combination of character displacement and size assortment, and change in body size was associated with a change in allopatry/sympatry, thus supporting the character‐displacement hypothesis.
The role of interspecific competition in the biogeography of island lizards.
3 Adaptation and Speciation in Greater Antillean Anoles
TLDR
Whether the Martinique (Ogden and Thorpe 2002), and other (Thorpe and Richard 2001) lizard cases represent examples of adaptive speciation remains to be investigated fully.
CRYPTIC SPECIATION IN THE ANADENOBOLUS EXCISUS MILLIPEDE SPECIES COMPLEX ON THE ISLAND OF JAMAICA
TLDR
It is concluded that A. excisus is actually a complex of three cryptic species and that morphological approaches to delineating millipede species may sometimes underestimate evolutionary diversity.
Adaptive radiation and community structure of Partula on Moorea
TLDR
The habitats occupied by snails of the genus Partula on the island of Moorea in French Polynesia are studied to show that the taxa divide the available habitat so that each predominates in its own characteristic environment.
Ecological and Evolutionary Determinants of the Species-Area Relation in Caribbean Anoline Lizards
TLDR
Detailed examination of several components of evolutionary diversification indicates that the species-area relation among the Greater Antilles primarily results because larger islands have increased number of habitat niches occupied and a greater number of closely related species that are ecologically similar and allopatrically distributed.
Character Displacement in Giant Rhinoceros Beetles
TLDR
Male morphology of two closely related rhinoceros beetles species indicates that morphological character displacement in sympatry was most complete in sexual organs, which may account for the process of existing species conserving themselves as integrated units by avoiding interspecific competition and enhancing reproductive isolation.

TLDR
Differences in head length and snout-vent length were computed for all combinations of Anolis species taken two at a time on the Greater Antilles to study the tendency to converge and diverge associated with structural-habitat similarity and spatial overlap.
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.

TLDR
There is no evidence in their analyses or arguments to change the previous conclusion that interspecific competition has played a role in the adaptive radiation of Darwin's Finches, and some unsolved problems in biogeography are drawn attention.

TLDR
The data suggest that the northern bimaculatus group is evolutionarily younger than the roquet group, hence has had less time for genetic divergence, and there is a geographic pattern discernible in the genetic distance data.

TLDR
A cladistic test of the hypothesis that the evolution of dioecy is favored in animal‐dispersed plants indicates that dioECy may have originated somewhat more often in such lineages, which must largely account for the observed species‐level correlation between dispersal and breeding system.
Population experiments with the Anolis lizards of St. Maarten and St. Eustatius.
TLDR
Results support a central assumption of competition theory: the strength of inter specific competition increases as the amount of interspecific resource partitioning decreases.

TLDR
There is now an accumulating fossil record from islands which shows that numerous species have declined in average maximum body size since the beginning of the Holocene, regardless of phylogenetic afffinities, habits, or even size of the species itself.
