... or the duration of rest–wake cycles provide a central mechanism for animals to exploit novel niches. The diversity of the >3000 cichlid species throughout the world provides a unique opportunity to examine variation in locomotor activity and rest. Lake Malawi alone is home to over 500 species of cichlids...

...Wayne J. Korzan; Brian P. Grone; Russell D. Fernald In many social species, individuals influence the reproductive capacity of conspecifics. In a well-studied African cichlid fish species, Astatotilapia burtoni , males are either dominant (D) and reproductively competent or non-dominant (ND...

To understand the relative contributions of social experience and physical environment on status, we used a highly territorial African cichlid fish species, Astatotilapia burtoni , that lives in a dynamic lek-like social...

The ability to study Aulonocara in the laboratory provides an opportunity to test the hypothesis that their reported ability to feed on invertebrate prey living in sandy substrates in their natural...

... during the early development period. The Amazonian cichlid Symphysodon spp. (discus fish) is unusual among fish species, in that both parents provide offspring with mucus secretions to feed from after hatching. This extensive provision of care, which can last up to a month, imposes a physiological demand...

...Brian E. Dalton; Thomas W. Cronin; N. Justin Marshall; Karen L. Carleton SUMMARY The extent of animal colouration is determined by an interplay between natural and sexual selection. Both forces probably shape colouration in the speciose, rock-dwelling cichlids of Lake Malawi. Sexual selection...

...T. J. Lisney; E. Studd; C. W. Hawryshyn SUMMARY The cichlid fish radiations of the African Great Lakes are an important model for evolutionary biology. Cichlids have diverse colour vision systems and predominately express three cone visual pigments. However, rare populations of spectrally distinct...

.... The African cichlid fish Astatotilapia burtoni has long been used as a model system to study how social interactions regulate neural and behavioral plasticity. In this species, males are either socially dominant and reproductively active or subordinate and reproductively suppressed. This phenotypic difference...

A prime example of socially regulated reproduction occurs in the cichlid fish Haplochromis burtoni , in which interactions between males...
