“…In these cases, the residents described precisely the size and coloration pattern of each species, as well as the aquatic environment of C. minimus. In general, this study followed the taxonomy proposed by WILSON & REEDER (2005), except for the genus Alouatta, which followed the taxonomy proposed by GREGORIN (2006).…”

“…For instance, A. caraya is a howler species that is characteristic of Central Brazil, occurring mainly within the limits of the Cerrado, where it is usually found in gallery forest formations and semideciduous forests (RYLANDS et al 1996, GREGORIN 2006. Together with Northeastern Argentina, the western region of the Southern Brazilian states is considered an area of sympatry between A. caraya and A. clamitans, which is characteristic of the south and southeastern portion of the Atlantic Rainforest.…”

“…Together with Northeastern Argentina, the western region of the Southern Brazilian states is considered an area of sympatry between A. caraya and A. clamitans, which is characteristic of the south and southeastern portion of the Atlantic Rainforest. These two species have mostly parapatric distributions, with sympatry regions along the Paraná and Uruguay rivers (HIRSCH et al 1991, DI BITETTI et al 1994, GREGORIN 2006, AGUIAR et al 2007a.…”

“…In addition, the specimens of A. clamitans, A. caraya and their possible hybrids collected by André Mayer during the 1940's and 1950's were obtained in municipalities in the vicinity of Porto Rico, in a region known as "Sertão do Rio Paraná" which includes a nearly 30 km stretch of the Paraná River between the municipalities of São Pedro do Paraná e Guairá (PR) (LORINI & PERSSON 1990, GREGORIN 2006, that also includes Porto Rico. At that time, primates were also collected in Porto São José, in the municipality of São Pedro do Paraná, which is adjacent to Porto Rico, upstream of the Paraná River.…”

“…Aguiar, personal observation). Specimens of A. clamitans were also collected in Querência do Norte, another municipality adjacent to Porto Rico downstream of the Paraná River (HIRSCH et al 1991, GREGORIN 2006. Also downstream of Porto Rico, more precisely in the Ilha Grande National Park, A. clamitans is still found in the Submontana Semideciduous Seasonal Forest in sympatry with A. caraya (AGUIAR et al 2007b).…”

Occurrence, local extinction and conservation of Primates in the corridor of the Upper Paraná River, with notes on other mammals

The region of Porto Rico, on the Upper Paraná River, is a contact zone between the Atlantic Rainforest and the Cerrado, with elements of the Pantanal wetlands. During surveys from September 2003 to September to 2005, we recorded the presence of non-volant mammals on 14 islands and the adjacent riverbanks. Surveys were by foot and by boat, and we also interviewed local people about the mammals of the region. Sightings of three primate species - Cebus nigritus (Goldfuss, 1809) (left margin of the river), C. libidinosus Spix, 1823 (right margin) and Alouatta caraya (Humboldt, 1812) (both margins and 12 islands) - were plotted on a satellite image. Alouatta clamitans Cabrera, 1940 was not recorded. However, interviews indicated that this species has occurred in this region in the past. The survey of mammals revealed the occurrence of 32 native species, a native genus with one or more unidentified species, and two introduced species [Lepus europaeus Pallas, 1778 and Sus scrofa (Linnaeus, 1758)]. The study discusses the permeability of the Paraná River to dispersal, as well as its potential as a geographical barrier to some species. Hypothesis on the local extinction of A. clamitans is also addressed. This study provides information that can be useful for promoting the conservation of this region.

Cytochrome b DNA sequence data (ca. 1,140 bp) of 44 Alouatta caraya, including 42 specimens from three localities of Brazil and two from Bolivia, were used for phylogenetic reconstructions and population studies. Seventeen haplotypes were identified, eight of which were present in more than one individual. Seven of these eight haplotypes were shared by individuals from a same locality and one by individuals from two localities. We found 26 variable sites along the entire gene, consisting of 18 transitions and eight transversions; most replacements occurring at the third codon position (65.39%) in contrast to first and second positions (26.92 and 7.69%, respectively). In the sample collected at Chapada dos Guimarães (Brazil), nucleotide and haplotype diversity estimates were pi=0.002325 and h=0.8772, respectively. Maximum parsimony analysis grouped all haplotypes in two clades, separating Bolivian haplotypes from Brazilian haplotypes, the grouping of which did not show a straightforward correspondence with geographic distribution. Median-joining and TCS network pointed to haplotypes 11 or 12 as the most likely ancestral ones. Mismatch distribution and the goodness-of-fit test (SSD estimate=0.0027; P=0.6999) indicated that the population from Chapada dos Guimarães experienced a demographic expansion, in agreement with the median-joining star-like pattern, although this finding could not be confirmed by Fu's F(s) test.

Cytochrome b DNA sequence data (ca. 1,140 bp) of 66 Alouatta belzebul from the Amazonian and the Atlantic Forests of Brazil were used for phylogenetic reconstructions and population studies. Our sample consisted of 60 specimens from the Amazonian Forest (captured in 1984 and 1998 in Pará-PA state) and six specimens from the Atlantic Forest (Paraíba-PB state). We found 32 haplotypes, 23 in PA-1984 (with 12 present in more than one individual), 11 in PA-1998 (with two present in more than one individual), and a single haplotype in the PB sample. Animals from PA-1984 and PA-1998 shared three haplotypes while animals from Pará and Paraíba did not share any haplotype. We found 57 variable sites, consisting of 53 transitions and four transversions, with most replacements occurring at third codon position (77.19%) and less frequently at first and second positions (10.53 and 12.28%, respectively). Genetic distance between all haplotypes varied between 0 and 1.2%. Nucleotide diversity estimates between PA-1984 haplotypes and PA-1998 haplotypes were the same (π=0.01), and haplotype diversity estimates were very similar (h=0.96 and 0.93 for PA-1984 and PA-1998, respectively). Maximum parsimony, median-joining, split decomposition, and TCS showed that PA and PB haplotypes had not drastically diverged and that subsequent radiation within these regions was not apparent. No temporal structure was found between PA-1984 and PA-1998. The sum of square deviation estimate for PA-1984 equaled 0.01 (P=0.23), in agreement with a hypothetical model of sudden expansion contrary to PA-1998 whose sum of square deviation estimate (0.40; P=0.04) was not compatible with this model, although the small sample size of PA-1998 as well as the smaller area of capture could have also accounted for this result. Fu's F(s) and R(2) statistical neutrality tests corroborated these propositions. Lack of drastic differentiation was attributable to the once existing connection between the Atlantic and the Amazonian forests at a non-distant past.
