| morphologic, karyotypic, and molecular evidence of a new form of chiropotes (primates, pitheciinae). | morphologic, karyotypic, and molecular analyses were carried out in 25 specimens of a distinct morph of chiropotes (henceforth termed chiropotes sp.) obtained from a number of localities in the brazilian amazon. pelage coloration clearly distinguishes the collected specimens and all other known species of this genus. a distinct karyotype was described for chiropotes sp. it differs from c. satanas chiropotes by two pericentric inversions, and from c. satanas utahicki by three, which suggests that ... | 2003 | 14610730 |
| new records and range expansion of the white bald uakari (cacajao calvus calvus, i. geoffroy, 1847) in central brazilian amazonia. | the white bald uakari (cacajao calvus calvus) is among the least studied of the amazonian primates and is found exclusively in remote areas of the central amazon. the geographic distribution of this subspecies is still uncertain, and information on current threats and its conservation status is sparse. in this paper, we identify new locations of occurrence and propose range expansion of the cacajao calvus calvus. between 2008 and 2010, six field expeditions were undertaken in the middle solimões ... | 2014 | 24193509 |
