title: New markers for new species: microsatellite loci and the East African cichlids.
abstract: The radiation of the East African cichlid fishes has engaged biologists for over a century. Because so much taxonomic diversity has evolved recently, they are an ideal natural system in which to study the process of speciation. Hypervariable microsatellite loci have been used to verify multiple paternity and maternity in cichlid broods, to quantify the fitness of cooperative breeders and reproductive parasites, to estimate effective population sizes in captive populations, and to illuminate the spatial and temporal scale of gene flow among natural populations. The patterns that have emerged from these studies often reflect important biological differences among taxa. The cichlid species of East Africa represent a large amount of taxonomic and adaptive diversity all neatly packaged into a single lineage and confined to a modest geographical area. Data from microsatellite loci are now providing us with the means to understand one of the world's most intriguing and instructive comparative evolutionary systems.
