As a graduate student, I worked on field studies and the genetic structure of Alcolapia grahami, a cichlid adapted to the most hostile environmental conditions (e.g. pH 10.0, 35-42◦C, anoxic night-time conditions) any teleost has been found to inhabit. In reconstructing the history of this fish using molecular genetic markers, the evidence supports balancing selection acting on the mitochondrial DNA given frequent and common haplotypes among physically and environmentally separated lagoons. As part of a large international research team, I participated in a comprehensive study of this cichlid that included ecological, genetic, biochemical, physiological and morphological studies. I contributed not only in the genetic survey of populations, but also examined the physiological differences related to survival and osmoregulation along a severe environmental gradient.
Adaptive airbreathing behaviour during anoxic (a lack of oxygen) in the water during the night. Magadi cichlids adapted their swimbladders into primitve airbreathing lung likely within 5,000 - 10,000 years.
