Hybridization and speciation among cichlids: the case of 'Wesafu', an ecotype cichlid
2010Fishes of the family Cichlidae are known for spectacular adaptive radiation and therefore serve as a model for evolutionary and ecological studies. They are highly speciated due to hybridization that frequently occur in the wild. The existence of an ecotype cichlid, ’wesafu’ in Epe Lagoon, Lagos, Nigeria appears to be the result of such hybridization ...

Chemical communication in cichlids: A mini-review
General and Comparative Endocrinology, 2015The family Cichlidae is well-known for pair-formation, parental care, territoriality, elaborate courtship and social organization. Do cichlids use chemical communication to mediate any of these behaviours? Early studies suggest that parent cichlids can discriminate between conspecific and heterospecific wrigglers (but not eggs) using olfactory cues ...

Respiratory Ecology of Cichlids
2021For fishes, the availability of dissolved oxygen (DO) can affect performance and fitness traits and influence distribution patterns. Hypoxia occurs naturally in habitats characterized by low mixing and/or light limitation such as dense wetlands and profundal zones of deep lakes.

Visualizing Speciation in Artificial Cichlid Fish
Artificial Life, 2006The Cichlid Speciation Project (CSP) is an ALife simulation system for investigating open problems in the speciation of African cichlid fish. The CSP can be used to perform a wide range of experiments that show that speciation is a natural consequence of certain biological systems. A visualization system capable of extracting the history of speciation

Hermaphroditism in Cichlid Fishes
1975I would like to discuss a peculiar type of hermaphroditism, which has been discovered in the ‘Mbuna’. The Mbuna are a group of cichlid fishes endemic to Lake Malawi. They are unique in various aspects of taxonomy, so that Fryer (1959), who made a fundamental ecological study of them, proposed to grant them the rank of a tribus. The Mbuna are small fish
