The initial sequencing of five cichlid genomes revealed an accumulation of genetic variation, including extensive copy number variation in cichlid lineages particularly those that have undergone dramatic evolutionary radiation. Gene duplication has t... Read More about The Genomic Substrate for Adaptive Radiation: Copy Number Variation across 12 Tribes of African Cichlid Species.

The genomic basis of cichlid fish adaptation within the deepwater “twilight zone” of Lake Malawi (2017)
Journal Article
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
Magalhaes, I. S., Smith, A. M., & Joyce, D. A. (2017). Quantifying mating success of territorial males and sneakers in a bower-building cichlid fish. Scientific reports, 7(1), doi:10.1038/srep41128

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
Nichols, P., Genner, M. J., van Oosterhout, C., Smith, A., Parsons, P., Sungani, H., …Joyce, D. A. (2015). Secondary contact seeds phenotypic novelty in cichlid fishes. Proceedings of the Royal Society B: Biological Sciences, 282(1798), https://doi.org/10.1098/rspb.2014.2272

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.

Gene duplication in an African cichlid adaptive radiation (2014)
Journal Article
Machado, H. E., Jui, G., Joyce, D. A., Reilly, C. R. L., Lunt, D. H., & Renn, S. C. (2014). Gene duplication in an African cichlid adaptive radiation. BMC Genomics, 15(1), 161. https://doi.org/10.1186/1471-2164-15-161

Background Gene duplication is a source of evolutionary innovation and can contribute to the divergence of lineages; however, the relative importance of this process remains to be determined. The explosive divergence of the African cichlid adaptive r... Read More about Gene duplication in an African cichlid adaptive radiation.

Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish (2013)
Journal Article
Joyce, D. A., Croft, G. E., & Magalhaes, I. S. (2013). Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish. PeerJ, 1(1), (e209). doi:10.7717/peerj.209. ISSN 2167-8359

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.

Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage (2011)

Moss, S. P., Joyce, D. A., Humphries, S., Tindall, K. J., & Lunt, D. H. (2011). Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage. Genome Biology and Evolution, 3(1), 1187-1196. doi:10.1093/gbe/evr090

We have developed a bioinformatics pipeline for the comparative evolutionary analysis of Ensembl genomes and have used it to analyze the introns of the five available teleost fish genomes. We show our pipeline to be a powerful tool for revealing vari... Read More about Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage.

Repeated colonization and hybridization in Lake Malawi cichlids (2011)
Journal Article

Through adaptive radiation, ancestral species rapidly diversify into multiple species with different ecological adaptations. The haplochromine cichlid fishes of the East African Great Lakes are considered classic examples of adaptive radiation, but o...
