Fig. 1From: Tol2 transposon-mediated transgenesis in the Midas cichlid (Amphilophus citrinellus) — towards understanding gene function and regulatory evolution in an ecological model system for rapid phenotypic diversificationThe study system. a-b Within the last 25,000 years Midas cichlids (Amphiliphus spp.; here Amphilophus amarillo from Lake Xiloá (a)) from Nicaragua (b) colonized several small crater lakes from the large lakes L. Nicaragua and L. Managua. Within the crater lakes, Midas cichlids underwent rapid and parallel adaptive evolution and formed several new speciesBack to article page
