A revision of the genus Astatoreochromis (Teleostei, Cichlidae), East-Africa [PDF]

open access: yes, 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.

Speciation through sensory drive in cichlid fish [PDF]

open access: yes, 2008
Theoretically, divergent selection on sensory systems can cause speciation through sensory drive. However, empirical evidence is rare and incomplete. Here we demonstrate sensory drive speciation within island populations of cichlid fish.

Cytoarchitecture of a Cichlid Fish Telencephalon [PDF]

open access: yesBrain, Behavior and Evolution, 2009
Although the telencephalon of ray-finned fishes has garnered considerable attention from comparative neuroanatomists, detailed descriptions of telencephalic organization are available for only a few species. This necessarily limits our understanding of telencephalic evolution, particularly in light of the extraordinary diversity of ray-finned fishes ...

Tempo and mode of diversification of Lake Tanganyika cichlid fishes [PDF]

open access: yes, 2008
Understanding the causes of disparities in species diversity across taxonomic groups and regions is a fundamental aim in evolutionary biology. Addressing these questions is difficult because of the need for densely sampled phylogenies and suitable ...

Movement of transposable elements contributes to cichlid diversity. [PDF]

open access: yes, 2020
African cichlid fishes are a prime model for studying speciation mechanisms. Despite the development of extensive genomic resources, it has been difficult to determine which sources of genetic variation are responsible for cichlid phenotypic variation ...

Analysis of the meiotic segregation in intergeneric hybrids of tilapias [PDF]

open access: yes, 2012
Tilapia species exhibit a large ecological diversity and an important propensity to interspecific hybridisation. This has been shown in the wild and used in aquaculture.

Introduced predator elicits deficient brood defence behaviour in a crater lake fish. [PDF]

open access: yesPLoS ONE, 2012
Introduced species represent one of the most serious global threats to biodiversity. In this field-based study, we assessed behavioural responses of brood tending cichlid fish to an invasive predator of their offspring.

Threatened fishes of the world: Coptodon walteri (Thys van den Audenaerde 1968) (Perciformes: Cichlidae)

open access: yesCroatian Journal of Fisheries, 2016
Coptodon walteri Thys van den Audenaerde 1968, an endemic cichlid of Ivory Coast and Liberia, is assessed as Near Threatened due to fishing pressure and loss of habitats, and aquatic pollution as a result of extensive clandestine gold mining in the bed ...

Early stages of sympatric homoploid hybrid speciation in crater lake cichlid fishes

open access: yesNature Communications, 2022
Here, the authors present a rare example of sympatric homoploid hybrid speciation, without ploidy changes, in the Midas cichlid fishes from Nicaragua. Midas cichlid hybrids occupy a different ecological niche, likely facilitated by body shape adaptations.

Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae)

open access: yesBrazilian Journal of Biology, 2021
Several species of Cichla successfully colonized lakes and reservoirs of Brazil, since the 1960’s, causing serious damage to local wildlife. In this study, 135 peacock bass were collected in a reservoir complex in order to identify if they represented a ...
