Species tree estimation for a deep phylogenetic divergence in the New World monkeys (Primates: Platyrrhini).
The estimation of a robust phylogeny is a necessary first step in understanding the biological diversification of the platyrrhines. Although the most recent phylogenies are generally robust, theyExpand

Molecular phylogenetic relationships and phenotypic diversity in miniaturized toadlets, genus Brachycephalus (Amphibia: Anura: Brachycephalidae).
Toadlets of the genus Brachycephalus are endemic to the Atlantic rainforests of southeastern and southern Brazil. The 14 species currently described have snout-vent lengths less than 18 mm and areExpand

Genitals Evolve Faster Than Other Traits In Anolis Lizards
We characterize the morphology of hemipenes in 25 Caribbean Anolis lizard species, and compare rates of evolution to those of traits related to ecology or visual signaling. Expand

Patterns of cranial shape diversification during the phylogenetic branching process of New World monkeys (Primates: Platyrrhini)
One of the central topics in evolutionary biology is understanding the processes responsible for phenotypic diversification related to ecological factors. New World monkeys are an excellent referenceExpand

A combined morphological and molecular phylogeny of the genus Chironius Fitzinger, 1826 (Serpentes: Colubridae)
Chironius is one of the most speciose genera of the South American colubrid snakes. Although the genus represents a well-known radiation of diurnal racers, its monophyly, affinities with otherExpand

Hemipenial Allometry in Anolis grahami
Abstract In animals with internal fertilization, the male genitalia often vary greatly, have complex morphology, and show fast rates of evolution. In studies of the evolution of such male genitalia,Expand

Are Diet Preferences Associated to Skulls Shape Diversification in Xenodontine Snakes?
Snakes are a highly successful group of vertebrates, within great diversity in habitat, diet, and morphology. The unique adaptations for the snake skull for ingesting large prey in more primitiveExpand

Taxonomic Status of Chironius multiventris and Chironius cochranae (Serpentes)
Abstract Recently four subspecies of Chironius multiventris were recognized as valid distinct species: C. m. foveatus, C. m. multiventris, C. m. cochranae, and C. m. septentrionalis. Although C.Expand
