Abstract
Phylogenetic relationships based on DNA sequence variation for the aldolase A intron V nuclear genomic region were evaluated and compared to phylogeni es based on mitochondrial DNA sequence variation among spider monkeys (Atel es), Samples of Ateles ranging from Central America throughout the Amazon B asin were sequenced to determine phylogenetic relationships among geographi cally widely distributed populations. Analysis of nuclear DNA sequences usi ng parsimony, maximum-likelihood, and genetic distance analyses produced si milar phylogenies, Four previously proposed monophyletic species of spider monkeys were: (1) Ateles paniscus, composed of haplotypes from the northeas tern Amazon Basin; (2) A, belzebuth, found in the western and southern Amaz on Basin; (3) A. hybridus, located primarily along the Magdalena River vall ey of Colombia; and (4) A. geoffroyi, including all haplotypes found in the Choco region of South America and throughout Central America. The nuclear phylograms were analyzed based on associated bootstrap support and confiden ce probabilities, Support from the nuclear DNA genome was less robust than support from the mitochondrial DNA data, most likely due to a level of sequ ence variation, which was 90% less than that of the mitochondrial DNA genom e. Nuclear DNA congruencies With mitochondrial DNA-based phylogenies, as su pported by the incongruence length difference and winning sites tests, prov ide further support for the suggested revisions in Ateles taxonomy that are contradictory to long-held taxonomies based on pelage variation.
