Genotoxicity of the herbicide formulation Roundup (glyphosate) in broad-snouted caiman (Caiman latirostris) evidenced by the Comet assay and the Micronucleus test.
The genotoxicity of pesticides is an issue of worldwide concern. The present study was undertaken to evaluate the genotoxic potential of a widely used herbicide formulation, Roundup (glyphosate), inExpand

COII: a useful tool for inferring phylogenetic relationships among New World monkeys (Primates, Platyrrhini)
In this study we evaluated the performance of the cytochrome c oxidase subunit II (COII) mitochondrial gene as a tool for inferring phylogenetic relationships among platyrrhines. Twenty‐nine COIIExpand
