| geographic distribution and population characteristics of the endangered white-fronted spider monkey (ateles marginatus) on the lower tapajós river in central brazilian amazonia. | the white-fronted spider monkey, ateles marginatus, is endemic to brazilian amazon between the tapajós and xingu rivers, and is classified as endangered due primarily to habitat loss. this study presents data on the distribution and relative abundance of the species in the northwestern corner of its distribution, on the lower tapajós river, centered on the 545,000 ha tapajós national forest (flona tapajós). quantitative data were collected in line transect surveys at 14 sites, and confirmatory i ... | 2009 | 19430965 |
| revisiting the phylogenetic relationships, biogeography, and taxonomy of spider monkeys (genus ateles) in light of new molecular data. | spider monkeys (ateles) are one of the most endangered groups of primates in the neotropics. the genus is widely distributed from mexico to the north of bolivia and includes many morphologically distinct forms in terms of pelage color and patterning. the taxonomy, phylogenetic relationships, and biogeographic history of the genus have been subject to much debate, making scientific communication difficult and creating challenges for conservation actions. we extracted dna from samples of all curre ... | 2015 | 25451801 |
