Genetic basis of adaptive radiation in East African cichlids
<p>East African cichlids are a paramount example of adaptive morphological radiation. The most dramatic difference among species occurs in oral jaw design and correlates with ecological niche partitioning. Convergent evolution of trophic forms between lakes suggests a common mechanism. What …

Genetic variation in fast-evolving East African cichlid fishes: an evolutionary perspective
Cichlid fishes from the East African Rift lakes Victoria, Tanganyika and Malawi represent a preeminent example of replicated and rapid evolutionary radiation. In this single natural system, numerous morphological (eg. jaw and tooth shape, color patterns, visual sensitivity), behavioral (eg. …

Evolution and Development of Pigmentation Patterns in East African Cichlid fishes
… and developmental genetics techniques. Using East African cichlid fishes as a model system, I aim to understand the evolutionary origin and diversification of anal fin egg-spots. Egg-spots are an innovation unique to the haplochromine cichlids; yellow to red annular markings typically on male …

Variation in neural crest development contributes to phenotypic diversification of East African cichlid fishes
… diversification. Despite low genetic divergence, East African cichlids harbour a spectacular intra- and interspecific morphological diversity. Akin to other vertebrates, a considerable proportion of hyper-diverse cichlid traits, such as craniofacial morphologies and pigmentation patterns, …
