Gene duplication in an African cichlid adaptive radiation [PDF]

open access: yes, 2014
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.

Desert cichlids

open access: yesNatura
Cichlids were given their name by the French zoologist Charles Lucien Bonaparte (1803-1857), a nephew of Napoleon, who borrowed the term from the Greek κίχλη (kichle), a word that in origin had the broad meaning of “wrasse” (a fish) or “thrush” (a bird).

Strategic growth decisions in helper cichlids [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Recently, it has been shown that group-living subordinate clownfish Amphiprion percula increase their growth rate after acquiring the dominant breeder male position in the group. Evidence was found for strategic growth adjustments of subordinate fishes depending on the threat of eviction, i.e.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

A new species of Gyrodactylus (Monogenea, Gyrodactylidae), an ectoparasite from the endemic Iranocichla hormuzensis (Teleostei, Cichlidae), the only Iranian cichlid [PDF]

open access: yes, 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 ...

Sensory modalities in cichlid fish behavior [PDF]

open access: yesCurrent Opinion in Behavioral Sciences, 2015
Among teleosts, cichlids are a great model for studies of evolution, behavior, diversity and speciation. Studies of cichlid sensory systems have revealed diverse sensory capabilities that vary among species. Hence, sensory systems are important for understanding cichlid behavior from proximate and ultimate points of view.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

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.

Larval Development of Rusty Cichlid Fish (Iodotropheus sprengerae Oliver & Loiselle, 1972): Morphological Observations

open access: yesActa Natura et Scientia, 2022
This study aimed to describe the larval development stage of rusty cichlid, Iodotropheus sprengerae morphologically. The rusty cichlid is a mouth-brooding haplochromine cichlid from Lake Malawi.
