The coincidence of ecological opportunity with hybridization explains rapid adaptive radiation in Lake Mweru cichlid fishes. Nature communications, 10(1), https://doi.org/10.1038/s41467-019-13278-z

© 2019, The Author(s). The process of adaptive radiation wasclassically hypothesized to require isolation of a lineage from its source (no gene flow) and from related species (no competition). Alternatively, hybridization between species may generate...

The genomic basis of cichlid fish adaptation within the deepwater “twilight zone” of Lake Malawi (2017)
Journal Article
Genner, M. J., Turner, G. F., Hahn, C., Genner, M. J., Turner, G. F., & Joyce, D. A. (2017). The genomic basis of cichlid fish adaptation within the deepwater “twilight zone” of Lake Malawi. Evolution Letters, 1(4), 184-198. https://doi.org/10.1002/evl3.20

Deepwater environments are characterized by low levels of available light at narrow spectra, great hydrostatic pressure, and low levels of dissolved oxygen—conditions predicted to exert highly specific selection pressures. In Lake Malawi over 800 cic... Read More about The genomic basis of cichlid fish adaptation within the deepwater “twilight zone” of Lake Malawi.

Quantifying mating success of territorial males and sneakers in a bower-building cichlid fish (2017)
Journal Article

The strategies and traits males evolve to mate with females are incredible in their diversity. Theory on the evolution of secondary sexual characters suggests that evolving any costly trait or strategy will pay off and stabilise in the population if...

Secondary contact seeds phenotypic novelty in cichlid fishes (2015)
Journal Article

Theory proposes that genomic admixture between formerly reproductively isolated populations can generate phenotypic novelty for selection to act upon. Secondary contact may therefore be a significant promoter of phenotypic novelty that allows species... Read More about Secondary contact seeds phenotypic novelty in cichlid fishes.

Reduced male aggression towards different phenotypes generating negative frequency-dependent intrasexual selection has been suggested as a mechanism to facilitate the invasion and maintenance of novel phenotypes in a population. To date, the best emp... Read More about Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish.
