Adaptive radiation refers to diversification from an ancestral species that produces
descendants adapted to use a great variety of distinct ecological niches. In this review, I …

Adaptive radiation is a response to natural selection and ecological opportunity involving
diversification of species and associated adaptations. Although evolutionary biologists have …

Several models have been proposed to suggest how the evolution of sex-determining
mechanisms might contribute to speciation. Here, we describe the inheritance of sex in 19 …

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

The rate at which different components of reproductive isolation accumulate with divergence
time between species has only been studied in a limited, but growing, number of species …

The evolutionary history of the endemic Lake Tanganyika cichlid tribe Tropheini, the sister
group of the species flocks of Lake Malawi and the Lake Victoria region, was reconstructed …

Background After a volcano erupts, a lake may form in the cooled crater and become an
isolated aquatic ecosystem. This makes fishes in crater lakes informative for understanding …

Lake Malawi's fishes are a source of food for millions and provide a livelihood for thousands
by encouraging tourism, fascinating the scientific fraternity, enchanting aquarists around the …

Lake Tanganyika comprises a cichlid species flock with substrate-breeding and
mouthbrooding lineages. While sexual selection via mate choice on male mating color is …

Background Cichlid fishes have been the subject of increasing scientific interest because of
their rapid adaptive radiation which has led to an extensive ecological diversity and their …
