The morphological systematics of the tufted capuchins is confusing. In an attempt to clarify the complex systematics and phylogeography of this taxon, we provide a first molecular analysis. We obtained mitochondrial cytochrome oxidase II (mtCOII) gene sequences from 49 tufted capuchins that had exact geographic origins from diverse lineages in Colombia,(More)
We sequenced mitochondrial genes of otter (Lontra longicaudis and Pteronura brasiliensis) and dolphin (Inia sp.) species to provide new systematics data and to test hypotheses that offer explanations as to the Amazon’s biodiversity. Four of the 11 hypotheses tested --Paleogeography (PH), Recent Lagoon (RLH), Hydrogeological Recent Change (HRCH), and Refugia(More)
We analyzed 115 Saguinus leucopus, from four Colombian departments (Antioquia, Bolivar, Caldas and Tolima ), for 701 bp of the mt COII gene and at 10 microsatellite loci to estimate gene diversity levels, possible molecular subspecies and historical demographic changes in this species. This endemic Colombian species showed an elevated gene diversity in this(More)
