A revision of the genus Astatoreochromis (Teleostei, Cichlidae), East-Africa [PDF]
, 2013 A taxonomic revision of the cichlid genus Astatoreochromis is presented. Eighteen meristic and 23 morphometric measurements were taken on 185 individuals, including type specimens.

Genome Biology and Evolution, 2019 The initial sequencing of 5 cichlid genomes revealed an accumulation of genetic variation, including extensive copy number variation in cichlid lineages particularly those that have undergone dramatic evolutionary radiation.

Cichlids: A Host of Opportunities for Evolutionary Parasitology
Trends in Parasitology, 2016 Thanks to high species diversity and a broad range of speciation mechanisms, cichlid fishes represent a textbook model in evolutionary biology. They are also of substantial economic value. Despite this importance, cichlid parasites remain understudied, although some are more diverse than their hosts.

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.ABSTRACT A major bottleneck to the projected expansion of the aquaculture industry is disease outbreaks caused by bacterial pathogens. Fish diseases caused by Flavobacterium pathogens are persistent in salmonid aquaculture, and treatment is limited to antimicrobials, which contaminate the aquatic environment and promote antimicrobial resistance ...

Mortality estimates of the four major Cichlid fishes of Umuoseriche Lake, Imo State, Nigeria [PDF]
, 2004 The mortality of the four major cichlid fishes of Urnuoseriche Lake is the subject of this paper. Mortality I as estimated by five techniques, vary amongst the cichlid fishes, viz, Tilapia carbrae, Tilapia mariac, Tilapia zilli cend (hrornoditilapfa ...

Genome Biology and Evolution, 2019 Why sex chromosomes turn over and remain undifferentiated in some taxa, whereas they degenerate in others, is still an area of ongoing research. The recurrent occurrence of homologous and homomorphic sex chromosomes in distantly related taxa suggests ...

Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]
, 2008 The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...

Science, 2018 Showing their stripes The adaptive radiation of East African cichlids has led to more than 1200 species across a number of lakes. Across these species, many convergent traits have emerged, including the presence or absence of horizontal stripes ...

Ecology and Evolution, Volume 15, Issue 12, December 2025.Male alternative reproductive tactics are widespread, often involving distinct morphs influenced by genetics or the environment. This study confirms two male morphs in the bush cricket Satizabalus jorgevargasi—larger, more colourful majors and smaller, duller minors—and tests how diet affects their development.

FishesThe radiation of cichlid species in the East African Great Lakes is remarkable and rapid. The population genetics of two deep-water Cyphotilapia species along the east coast of Lake Tanganyika from Burundi to southern Tanzania was determined using ddRAD ...
