Epigenetic variability and inheritance in East African cichlid fishes
The hundreds of cichlid species forming part of the radiation of East African Lakes show a remarkable diversity of phenotypic and ecological adaptation. Despite this, recent studies highlighted that genetic diversity within the radiation is among the lowest ever observed in vertebrates. Such a high …

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 …

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. …

A role for environmental epigenetics in the rapid diversification of East African cichlid fishes
… interactions remains unclear. Here, I use East African cichlid fishes—a model system for phenotypic plasticity and rapid evolution—to decipher the role of chromatin regulation in the establishment of phenotypic diversity in novel environments. To illustrate chromatin state dynamics …

Variation in neural crest development contributes to phenotypic diversification of East African cichlid fishes
The cichlid fishes comprise the largest extant vertebrate family and are the quintessential example of rapid “explosive” adaptive radiations and phenotypic diversification. Despite low genetic divergence, East African cichlids harbour a spectacular intra- and interspecific morphological diversity. …
