author keywords: adaptation; Cichlidae; fish diversification; quantitative trait loci
topics (OpenAlex): Morphological variations and asymmetry; Genetic diversity and population structure; Genetic and phenotypic traits in livestock
TL;DR: It is found that convergent body shape phenotypes commonly observed across fish clades are most likely due to distinct genetic and molecular mechanisms. (via Semantic Scholar)

2022 journal article

Morphometric and Genetic Description of Trophic Adaptations in Cichlid Fishes

Biology, 11(8), 1165.

By: L. DeLorenzo *, V. DeBrock *, A. Carmona Baez n , P. Ciccotto n, E. Peterson n, C. Stull n, N. Roberts n, R. Roberts n , K. Powder *

author keywords: craniofacial; quantitative trait loci; geometric morphometrics
topics (OpenAlex): Morphological variations and asymmetry; Fish biology, ecology, and behavior; Genetic diversity and population structure
TL;DR: The genetic and molecular origins of trophic adaptation using Lake Malawi cichlids, which have undergone an exemplary evolutionary radiation, suggest that craniofacial traits are mostly inherited as separate modules, which confers a high potential for the evolution of morphological diversity.

Peterson, E. N., Cline, M. E., Moore, E. C., Roberts, N. B., & Roberts, R. B. (2017, April 25). Die Naturwissenschaften, Vol. 104.

By: E. Peterson n, M. Cline n, E. Moore n, N. Roberts n & R. Roberts n 

author keywords: Sex chromosome; Genetic sex determination; Cichlid; Fish; Astatotilapia calliptera
MeSH headings : Animal Distribution; Animals; Cichlids / classification; Cichlids / genetics; Cichlids / physiology; Female; Genetic Markers / genetics; Male; Sex Chromosomes / genetics; Sex Determination Processes / genetics; Species Specificity

TL;DR: This study identifies a male heterogametic XY system segregating at linkage group (LG) 7 in an A. calliptera line that originated from Lake Malawi, at a locus previously shown to act as an XY sex determination system in multiple species of Lake Malawian cichlids. (via Semantic Scholar)

Roberts, N. B., Juntti, S. A., Coyle, K. P., Dumont, B. L., Stanley, M. K., Ryan, A. Q., … Roberts, R. B. (2016, October 26). BMC Genomics, Vol. 17.

By: N. Roberts n, S. Juntti *, K. Coyle n, B. Dumont n, M. Stanley n, A. Ryan  n, R. Fernald *, R. Roberts n 

author keywords: Sex determination; Polygenic sex determination; Cichlid; Fish; Evolution; Astatotilapia burtoni
MeSH headings : Animals; Cichlids / genetics; Evolution, Molecular; Female; Genetic Association Studies; Genetic Linkage; Inheritance Patterns; Male; Penetrance; Polymorphism, Single Nucleotide; Sex Determination Processes / genetics; Sex Ratio
topics (OpenAlex): Genetic and Clinical Aspects of Sex Determination and Chromosomal Abnormalities; Reproductive biology and impacts on aquatic species; Demographic Trends and Gender Preferences
TL;DR: Mapping results supporting the presence of multiple, novel sex determination alleles in A. burtoni provide a foundation for future mapping of multiple sex determination genes and their interactions and provide important context for their use in behavioral studies, as well as studies of the evolution of genetic sex determination and sexual conflicts in East African cichlids.
