There is increasing evidence that phenotypic plasticity can promote population divergence
by facilitating phenotypic diversification and, eventually, genetic divergence. When a …

Most organisms represent specialized forms that arose as a result of natural selection and
genetic drift to occupy distinct ecological niches. In animals, this process of specialization …

GG Simpson, one of the chief architects of evolutionary biology's modern synthesis,
proposed that diversification occurs on a macroevolutionary adaptive landscape, but …

Replicate radiations provide powerful comparative systems to address questions about the
interplay between opportunity and innovation in driving episodes of diversification and the …

The spiny-finned teleost fishes (Acanthomorpha) include nearly one-third of all living
vertebrate species and assume a bewildering array of bodyplans, but the macroevolutionary …

Background How particular changes in functional morphology can repeatedly promote
ecological diversification is an active area of evolutionary investigation. The African rift-lake …

The consequences of among‐individual phenotypic variation for the performance and
ecological success of populations and species has attracted growing interest in recent …

Cichlid fishes are hypothesized to encompass several independent adaptive radiations that
display increased diversification rates and impressive ecological heterogeneity. Here, I …

Phenotypic plasticity is the ability of organisms with a given genotype to develop different
phenotypes according to environmental stimuli, resulting in individuals that are better …

Pike cichlids form the largest clade of Neotropical cichlids, with over 100 species presently
classified in two genera: Crenicichla (93 species widespread in rivers of South America east …
