Congratulations to Max and Annika and all their coauthors on their new paper! Cichlid fishes are exceptionally fast at speciation. Lake Tanganyika is only about 10 million years old and has about 250 endemically evolved cichlid species. Our lab collaborated with Lake Tanganika cichlid species experts the Salzburger lab, and found that cichlids have diverse activity patterns. Some are night active (nocturnal), some day active (diurnal) and others are most active during the dawn and dusk, while others have no clear rhythm. This temporal niche partitioning could have supported the rapid diversification of these species.

Max now has his own lab at the University of Toronto.
