- Color discrimination thresholds in a cichlid fish: Metriaclima benetos
Summary: Color discrimination thresholds of cichlids can be obtained through visually mediated tasks, enabling investigation of the role of vision in cichlid ecology, sexual selection and speciation.
- Variable vision in variable environments: the visual system of an invasive cichlid (Cichla monoculus) in Lake Gatun, Panama
Summary: Examination of the visual system plasticity of the peacock bass, Cichla monoculus, shows that this species adapts to a changing environment by alternating the use of chromophores A1 and A2, and through differential gene expression in the retina.
- Hypoxia-induced changes in hemoglobins of Lake Victoria cichlids
Summary: Four cichlids of the Lake Victoria species flock raised under hypoxia exhibit a remarkable change in isohemoglobin pattern, corresponding with improved hemoglobin O2-binding affinity.
- Kinematics of mouthbrooding in Oreochromis niloticus (Cichlidae)
Highlighted Article: Mouthbrooding cichlids regularly use posterior-to-anterior waves of head expansion and significant inflow through the opercular slits to move the brood anteriorly away from the gills.
