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). doi:10.1002/evl3.20. ISSN 2056-3744

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

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... Read More

Secondary contact seeds phenotypic novelty in cichlid fishes (2014)
Journal Article
Genner, M. J., Nichols, P., van Oosterhout, C., Smith, A., Parsons, P., Sungani, H., …Van Oosterhout, C. (2015). Secondary contact seeds phenotypic novelty in cichlid fishes. Proceedings. the Royal Society. Biological sciences /, 282(1798), (20142272). doi:10.1098/rspb.2014.2272. ISSN 0962-8452

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

Gene duplication in an African cichlid adaptive radiation (2014)
Journal Article
Machado, H. E., Joyce, D. A., Reilly, 3., Renn, S. C., Reilly, C. R., Renn, S. C., …Renn, S. (2014). Gene duplication in an African cichlid adaptive radiation. BMC Genomics, 15(1), (161). doi:10.1186/1471-2164-15-161. ISSN 1471-2164

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

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

Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage (2011)
Journal Article
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. ISSN 1759-6653

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

Repeated colonization and hybridization in Lake Malawi cichlids (2011)
Journal Article
Joyce, D., Lunt, D. H., Genner, M. J., Turner, G. F., Bills, R., & Seehausen, O. (2011). Repeated colonization and hybridization in Lake Malawi cichlids. Current biology : CB, 21(3), (R108-R109). doi:10.1016/j.cub.2010.11.029. ISSN 0960-9822

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... Read More

Sequential female assessment drives complex sexual selection on bower shape in a cichlid fish (2010)
Journal Article
Joyce, D. A., Genner, M. J., Haesler, M. P., & Young, K. A. (2010). Sequential female assessment drives complex sexual selection on bower shape in a cichlid fish. Evolution, 64(8), (2246-2253). doi:10.1111/j.1558-5646.2010.00984.x. ISSN 0014-3820

In many animals, sexual selection on male traits results from female mate choice decisions made during a sequence of courtship behaviors. We use a bower-building cichlid fish, Nyassachromis cf. microcephalus, to show how applying standard selection a... Read More

Solutions for PCR, cloning and sequencing errors in population genetic analysis (2009)
Journal Article
Cummings, S. M., McMullan, M., Joyce, D. A., & van Oosterhout, C. (2010). Solutions for PCR, cloning and sequencing errors in population genetic analysis. Conservation genetics, 11(3), (1095-1097). doi:10.1007/s10592-009-9864-6. ISSN 1566-0621

PCR and sequencing artefacts can seriously bias population genetic analyses, particularly of populations with low genetic variation such as endangered vertebrate populations. Here, we estimate the error rates, discuss their population genetics implic... Read More

Simple practical approach for sample loading prior to DNA extraction using a silica monolith in a microfluidic device (2009)
Journal Article
Shaw, K. J., Docker, P. T., Haswell, S. J., Joyce, D. A., Dyer, C. E., Greenman, J., & Greenway, G. M. (2009). Simple practical approach for sample loading prior to DNA extraction using a silica monolith in a microfluidic device. Lab on a chip, 9(23), 3430-3432. doi:10.1039/b913309g

A novel DNA loading methodology is presented for performing DNA extraction on a microfluidic system. DNA in a chaotropic salt solution was manually loaded onto a silica monolith orthogonal to the subsequent flow of wash and elution solutions. DNA was... Read More

Indirect mate choice, direct mate choice and species recognition in a bower-building cichlid fish lek (2008)
Journal Article
