A new species of Gyrodactylus (Monogenea, Gyrodactylidae), an ectoparasite from the endemic Iranocichla hormuzensis (Teleostei, Cichlidae), the only Iranian cichlid [PDF]
, 2012 Iranocichla hormuzensis occupies a biogeographically peculiar position. This endemic of southern Iran is the only Iranian cichlid. While it is phylogenetically related to African oreochromine members of the cichlid family, it remains unclear how it has ...

Crater lake cichlids individually specialize along the benthic-limnetic axis [PDF]
, 2014 A common pattern of adaptive diversification in freshwater fishes is the repeated evolution of elongated open water (limnetic) species and high-bodied shore (benthic) species from generalist ancestors.

Sensory Drive in Cichlid Speciation [PDF]
The American Naturalist, 2006 The role of selection in speciation is a central yet poorly understood problem in evolutionary biology. The rapid radiations of extremely colorful cichlid fish in African lakes have fueled the hypothesis that sexual selection can drive species divergence without geographical isolation.

Ecology and Evolution, 2021 Cichlids inhabiting the Great Lakes of Africa have radiated extremely rapidly, with Lake Malaŵi harboring some 850 species. This rapid radiation may be linked to the diversity in behaviors, sexual selection, and phenotypic plasticity.

Evolutionary ecology of opsin gene sequence, expression and repertoire. [PDF]
, 2017 Linking molecular evolution to biological function is a long-standing challenge in evolutionary biology. Some of the best examples of this involve opsins, the genes that encode the molecular basis of light reception.

Hybridisation generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]
, 2016 Compared to other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.

The Midas cichlid species complex: incipient sympatric speciation in Nicaraguan cichlid fishes? [PDF]
Molecular Ecology, 2004 AbstractSympatric speciation is a contentious concept, although theoretical models as well as empirical evidence support its relevance in evolutionary biology. The Midas cichlid species complex (Amphilophus citrinellus,labiatus,zaliosus) from several crater lakes in Nicaragua fits several of the key characteristics of a sympatric speciation model.

Gene coexpression networks reveal molecular interactions underlying cichlid jaw modularity
BMC Ecology and Evolution, 2021 Background The oral and pharyngeal jaw of cichlid fishes are a classic example of evolutionary modularity as their functional decoupling boosted trophic diversification and contributed to the success of cichlid adaptive radiations. Most studies until now
