We describe a phylogenetic and spatial approach to the comparative study of character displacement and other coevolutionary phenomena. The method is developed as an in‐depth study of blossom morphology in 37 populations of the Neotropical vine Dalechampia scandens. We test the hypothesis that among‐population variation in blossom morphology is due largely to local adaptation to avoid competition from other species of Dalechampia that utilize the same restricted set of pollinators. Because… Expand
Evolution of Thermal Physiology in Liolaemus Lizards: Adaptation, Phylogenetic Inertia, and Niche Tracking
TLDR
It is shown how phylogenetic comparative methods can be used to test hypotheses that may help resolve the paradox of complex quantitative characters that are highly evolvable and adapted to the local environment while also showing evidence of strong phylogenetic effects and stasis. Expand
ECOLOGICAL AND REPRODUCTIVE CHARACTER DISPLACEMENT OF AN ENVIRONMENTAL GRADIENT
  • E. Goldberg, R. Lande

  • 2006
TLDR
It is shown that interspecific hybridization (when hybrids are inviable), even in very small amounts, has marked effects on the shape and stability of borders between species and the nature of character displacement, and is recommended for more careful spatial sampling in character displacement studies. Expand
Parallel evolution and ecological selection: replicated character displacement in spadefoot toads
TLDR
Both phylogenetic and population genetic evidence is presented indicating that the same divergent trait, which minimizes resource competition with the heterospecific, has arisen independently in multiple sympatric populations, providing strong indirect support for competition's role in divergent traits evolution.

AN INTRASPECIFIC COMPATATIVE ANALYSIS OF CHARACTER DIVERGENCE BETWEEN SYMPATRIC SPECIES
  • P. Marko

  • Evolution; international journal of organic evolution
  • 2005
TLDR
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. Expand
Ecological and community‐wide character displacement: the next generation
TLDR
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. Expand
Phylogeographical analysis of character displacement in feeding phenotypes of snail-feeding Acoptolabrus ground beetles
Ecological character displacement predicts that interspecific resource competition results in greater trait divergence between species in sympatry than in allopatry. However, other processes, suchExpand
Ecological Character Displacement
TLDR
Ecological character displacement, the subject of this article, helps to understand how complex communities are built up from simpler ones through ecological adjustments of the constituent species. Expand
ASSESSING CURRENT ADAPTATION AND PHYLOGENETIC INERTIA AS EXPLANATIONS OF TRAIT EVOLUTION:THE NEED FOR CONTROLLED COMPARISONS
TLDR
It is shown that the method of controlled comparisons can be viewed as a meta‐method, which can be implemented in many ways, and is illustrated by an analysis of sex‐ratio data for fig wasps, which suggests that current adaptation and phylogenetic inertia influence this trait. Expand
Ecological Character Displacement in Adaptive Radiation
TLDR
The evidence suggests that character displacement occurs frequently in nature, and it probably plays an important role in the evolution of diversity in many adaptive radiations. Expand
THE GEOGRAPHICAL PATTERN OF SPECIATION AND FLORAL DIVERSIFICATION IN THE NEOTROPICS: THE TRIBE SINNINGIEAE (GESNERIACEAE) AS A CASE STUDY
TLDR
The results failed to indicate a tendency for sympatric taxa to minimize morphological and phenological overlap (geographic exclusion and/or character displacement hypotheses), and point toward adaptation in phenology to local conditions and buildup of sympatries at random with respect to flower morphology.

Character Displacement and the Adaptive Divergence of Finches on Islands and Continents
TLDR
It is shown that the amount of divergence is greater in the Galapagos and Hawaiian finches, even when only beak-size divergence in the granivorous component is considered, suggesting that community-wide character displacement involving many taxa is common. Expand

TLDR
It is shown by simulation and analytical observations that the CSC is not valid under frequency dependent selection, and that the ESS is the limiting case of QGR as intraspecific phenotypic variation goes to zero, and a fourth approach, termed “Quantitative Genetic Optimization” (QGO) analysis, is suggested.

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. Expand

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. Expand
Ecological Causes of Adaptive Radiation
TLDR
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.

Populations of the lizard Anolis sagrei, introduced onto small islands from a nearby source, differentiated from each other rapidly over a 10–14-year period, with the more different the recipient island's vegetation from that of the source, the greater the magnitude of differentiation. Expand
