I consider the differing amounts of adaptive divergence on continents and remote archipelagoes as a source of evidence for ecological character displacement. A classical example is the accelerated evolution of morphological differences between finch species on the Galapagos and Hawaii, thought to result from an absence of competitor taxa on the islands. I show that the amount of divergence is greater in the Galapagos and Hawaiian finches, even when only beak-size divergence in the granivorous… 

Character displacement in some Cnemidophorus lizards revisited: a phylogenetic analysis.

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.

Convergent patterns of adaptive radiation between island and mainland Anolis lizards

It is shown that the island and mainland anole faunas exhibit exceptional morphological convergence, suggesting that they are more similar than previously understood and that replicated radiations occur beyond island settings more often than previously recognized.

Population variation and hybridization: Comparison of finches from two archipelagos

Results of published electrophoretic studies of genetic variation suggest that the early phase of differentiation, involving occasional introgressive hybridization, may last for up to 5 million years.

Ecological Character Displacement and Speciation in Sticklebacks

Evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia is presented and the possibility that competition for food has played a critical role in the divergence between species is considered.

Ecological character displacement in the face of gene flow: Evidence from two species of nightingales

Analysis of patterns of morphological variation in sympatric and allopatric populations of two hybridizing species of birds suggests that interspecific competition for food resources can drive species divergence even in the face of ongoing hybridization.

The Causes of Evolutionary Radiations in Archipelagoes: Passerine Birds in the Lesser Antilles

Analysis of genetic divergence among island populations in the Lesser Antilles reveals evidence of both prolonged independent evolution and re‐expansion of differentiated island populations through the archipelago but little evidence of secondary sympatry of divergent genetic lineages.

Evidence for ecological speciation in sticklebacks is weakest, but there are several hints of its importance: speciation was rapid and accompanied by divergence into different ecological niches; selection against hybrids is stronger in the wild than in the laboratory, which suggests that hybrid fitness depends on ecological context.

The role of geography and ecological opportunity in the diversification of day geckos (Phelsuma).

Rates of morphological evolution are higher in both the Mascarene and Seychelles archipelagos compared to rates on Madagascar, suggesting that ecological opportunity is an important factor in diversification of day gecko species.

Ecological and community‐wide character displacement: the next generation

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.

AN INTRASPECIFIC COMPATATIVE ANALYSIS OF CHARACTER DIVERGENCE BETWEEN SYMPATRIC SPECIES

Geographic variation within two sibling species of rocky‐shore gastropods that have partially overlapping distributions in central California is characterized, indicating that once advantageous traits arise, demographic processes, such as recurrent gene flow between established populations and extinction and recolonization, are important factors contributing to the geographic pattern of sympatric character divergence.

EVIDENCE FOR ECOLOGICAL CHARACTER DISPLACEMENT IN WESTERN AMERICAN CATOSTOMID FISHES

The weakness of the available evidence for competitive character displacement lies in the difficulty of establishing unambiguously that the character state of a species changes under natural selection arising from the presence of one or more species similar to it ecologically.

Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow, and considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.

The aim of this work is to test the hypothesis of interspecific competition, which has been critically debated recently, and can be returned to Darwin's Finches to perform such tests without circularity.

A field study is reported which tested the argument that competition has influenced the distributions on low islands, against two alternative hypotheses based on Bowman's (1961) suggestions.

Recurrent patterns of natural selection in a population of Darwin's finches

It is shown that in two subsequent periods of moderate to high adult mortality (1980 and 1982), the population was subject to the same selection as before, and beak depth and body weight were commonly under direct selection to increase but, surprisingly, beak width was directly selected to decrease.

It is concluded that food supply and interspecific competition have jointly determined the ecological course of the radiation of Darwin's finches and the resulting pattern of species diversity.

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.

Variation in the size and shape of Darwin's finches

It is shown that the tree finches have relatively long legs (tarsi), and that these finches as well as the ground finches which spend most time scratching on the ground or climbing in cacti also have a relatively long hallux (hind toe).

Genetic Revolutions, Founder Effects, and Speciation

It is argued that, although founder effects may cause speciation under sufficiently stringent conditions, they are only one extreme of a continuous range of possibilities, and divergence may be driven in a variety of ways, without the need for drastic external changes.
