Research overview: the ocelot lineage and the Leopardus radiation

The ocelot lineage comprises the small spotted cats of the Americas, nearly all placed in the genus Leopardus, and represents a relatively recent and rapid radiation. This overview surveys the group, including the ocelot, margay, oncilla, Geoffroy's cat, kodkod, pampas cat, and Andean mountain cat, and discusses how molecular phylogenetics resolved their relationships. It explains that the lineage diversified after cats reached South America during the Great American Biotic Interchange, producing many species over a short timespan. The piece notes the taxonomic challenges this rapid radiation creates, including cryptic species, hybridization, and unstable species counts. It highlights the distinctive chromosome number shared by Leopardus species and how the lineage exemplifies how a single colonization can fuel an explosive burst of felid speciation in a new continent.
