Molecular systematics and biogeography of the Neotropical monkey genus, Alouatta.
TLDR
Molecular clock-based estimates of branching times indicated that contemporary howler monkey species originated in the late Miocene and Pliocene, not the Pleistocene, and the causes of Alouatta diversification were more difficult to pin down, although it is posit that the initial cis- and trans-Andean split in the genus was caused by theLate Miocene completion of the northern Andes.

Mitochondrial DNA Phylogeny of the Family Cichlidae: Monophyly and Fast Molecular Evolution of the Neotropical Assemblage
TLDR
The cichlid phylogeny suggests drift-vicariance events, consistent with the fragmentation of Gondwana, to explain current biogeographic distributions and relative rate tests suggest that Neotropical cICHlids have experienced accelerated rates of molecular evolution. Expand
Molecular phylogeny of the New World monkeys (Platyrrhini, primates).
TLDR
The sister-group relationships of Brachyteles and Lagothrix, Saguinus and Leontopithecus, and Callimico with a Cebuella/Callithrix clade is not as well supported by the parsimony and bootstrap analyses and is not incorporated in the proposed cladistic classification. Expand
Can molecular data place each neotropical monkey in its own branch?
TLDR
Maximum Parsimony, Maximum Likelihood and Neighbor-Joining analyses suggested three monophyletic families that emerged almost at the same time during primate radiation, including the Cebidae, grouping Aotus, Cebus and Saimiri with the small callitrichines. Expand
The Cytochrome b Gene as a Phylogenetic Marker: The Limits of Resolution for Analyzing Relationships Among Cichlid Fishes
TLDR
Despite some limitations of cyt-b as a phylogenetic marker, this gene either alone or in combination with other data sets yields a tree that is in agreement with the well-established phylogeny of cichlid fish. Expand
Phylogenetic relationships of the New World titi monkeys (Callicebus): first appraisal of taxonomy based on molecular evidence
TLDR
Considering molecular, morphological and biogeographic evidence, a new genus level taxonomy for titi monkeys is proposed: Cheracebus n. Expand
DNA evidence on the phylogenetic systematics of New World monkeys: support for the sister-grouping of Cebus and Saimiri from two unlinked nuclear genes.
TLDR
The present evidence is best represented in an interim cladistic classification of ceboids by dividing the superfamily Ceboidea into three families: Atelidae, Pitheciidae, and Cebidae. Expand
Update on the Phylogenetic Systematics of New World Monkeys: Further DNA Evidence for Placing the Pygmy Marmoset (Cebuella) within the Genus Callithrix
TLDR
The DNA evidence shows not only that Callithrix must include C. pygmaea to be monophyletic but also that the times of separation of pyGmaea and the argentata and jacchus species groups from one another are to be expected for species in a single genus. Expand
Marmoset phylogenetics, conservation perspectives, and evolution of the mtDNA control region.
TLDR
The phylogenetic analyses provide convincing support for a split between the Atlantic forest and Amazonian marmosets, with the inclusion of the pygmy marmoset (Cebuella pygmaea) at the base of the Amazonian clade. Expand
Population genetic structuring of the king weakfish, Macrodon ancylodon (Sciaenidae), in Atlantic coastal waters of South America: deep genetic divergence without morphological change
TLDR
Throughout its range M. ancylodon inhabits the same, or very similar niche; thus, stabilizing selection probably promotes the retention of highly conserved morphology despite deep genetic divergence at the mitochondrial DNA cytochrome b. Expand
