Sensory Drive in Cichlid Speciation [PDF]
The American Naturalist, 2006 The role of selection in speciation is a central yet poorly understood problem in evolutionary biology. The rapid radiations of extremely colorful cichlid fish in African lakes have fueled the hypothesis that sexual selection can drive species divergence without geographical isolation.

Ecology and Evolution, 2021 Cichlids inhabiting the Great Lakes of Africa have radiated extremely rapidly, with Lake Malaŵi harboring some 850 species. This rapid radiation may be linked to the diversity in behaviors, sexual selection, and phenotypic plasticity.

Evolutionary ecology of opsin gene sequence, expression and repertoire. [PDF]
, 2017 Linking molecular evolution to biological function is a long-standing challenge in evolutionary biology. Some of the best examples of this involve opsins, the genes that encode the molecular basis of light reception.

bioRxiv, 2019 The adaptive radiation of cichlid fishes in East Afrian Lake Malawi encompasses over 500 species that are believed to have evolved within the last 800 thousand years from a common founder population.

Gene expression dynamics during rapid organismal diversification in African cichlid fishes
Nature Ecology & Evolution, 2020 Changes in gene expression play a fundamental role in phenotypic evolution. Transcriptome evolutionary dynamics have so far mainly been compared among distantly related species and remain largely unexplored during rapid organismal diversification, in ...

Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae)
Brazilian Journal of Biology, 2021 Several species of Cichla successfully colonized lakes and reservoirs of Brazil, since the 1960’s, causing serious damage to local wildlife. In this study, 135 peacock bass were collected in a reservoir complex in order to identify if they represented a ...

Genetic Variation and Hybridization in Evolutionary Radiations of Cichlid Fishes.
Annual Review of Animal Biosciences, 2020 Evolutionary radiations are responsible for much of the variation in biodiversity. Cichlid fishes are well known for spectacular evolutionary radiations, as they have repeatedly evolved into large and phenotypically diverse arrays of species.

Hybrid Breakdown in Cichlid Fish
PLOS ONE, 2015 Studies from a wide diversity of taxa have shown a negative relationship between genetic compatibility and the divergence time of hybridizing genomes. Theory predicts the main breakdown of fitness to happen after the F1 hybrid generation, when heterosis subsides and recessive allelic (Dobzhansky-Muller) incompatibilities are increasingly unmasked.

Nature Communications, 2019 The process of adaptive radiation was classically hypothesized to require isolation of a lineage from its source (no gene flow) and from related species (no competition).
