Neotropical Primates 12 1: Johns Hopkins University Press. The Nigriffrons Grande nucleus had the greatest secondary forest availability, and the tourist pressure is often more intense, compared with the other nuclei.

Rodents of Unusual Size. Habitat use To obtain a reliable statistical analysis, the frequency of each available habitat, as well as the titi’s sightings obtained on each nucleus were grouped and analyzed, statistically, in a global way. In the CSP, C. Ngirifrons do Instituto Florestal 5 2: Barbara Brown’s titi C.

Sakis, uakaris, and titi monkeys, p. The average size of troops found in this study was 2. Some of this variation can be explained by sample differences and systematic errors that may arrise whith violations of the basic assumptions of line transect census theory, but can we hypothesize this as adaptations to perturbation?

Unlike in many other monkeys, the tail is not prehensile 2 6. Black-fronted titi [1] Black-fronted titi in PradosBrazil Conservation status.

Diet We observed the titis consume 15 species belonging to nine families. Transects length varied from 0.

Loud calls can be heard over long distances due to their high amplitude and low frequency. Share on Facebook Tweet Send email. Western red colobus Procolobus badius. Bolivian titi Callicebus modestus. The density and relative abundance estimates of the present study conform to similar studies carried out with species of the Callicebus genus in Brazilian Atlantic Forest Tab. Observations of plant species consumed by Callicebuus.


This information is awaiting authentication by a species expert, and will be updated as soon as possible. Views Read Edit View history. The use of disturbed and undisturbed forest by masked titi monkeys Callicebus personatus nigriffrons is proportional to food availability.

Table II presents this global abundance index as well as the same index for each nucleus. The number of sessions in each trail varied from 15 to 25, so that the total sample effort in each trail was approximately the same for that nucleus. In the Neotropics, mated pairs of socially monogamous titi monkeys genus Callicebus emit conspicuous, coordinated loud calls.

It may NOT be used within Apps. Nigritrons Exotic Forest and the Initial Secondary Forest habitats didn’t obtain any titi records and the Late Secondary Forest habitat obtained an inferior number than expected, while the Araucaria Forest and the “Primary” Forest obtained more records than it was expected. Black bearded saki C. Black-fronted titi monkeys create loud calls by combining a finite number of syllables to form more complex phrases, which are assembled to compose long sequences of loud calls.


The perpendicular sighting distances were tested for normality Kolmogorov-Smirnov: Academic Press, New York. The collection of ancillary data during the census allowed the determination of diet and habitat use by the titis groups, and results show a relative adaptability to disturbed habitats. We also observed some individuals ingesting arthropods on three occasions, indicating this food item may complete the titis diet.

Fieldiana Zoology These calls nigrifronns commonly used for both within- and between-group communication in many bird and primate species. The callocebus titi monkey is active during the day and spends most, if not all, of its time in the tree canopy 7. The dominant habitat observed along each m interval of the transects was assigned to one of these categories, providing an estimate of the relative cover of each forest type. Conservation Biology 14 1: The black-fronted titi monkey Callicebus nigrifrons is a small New World monkey with a black face, forehead and ears 5.

Neotropical Primates 10 Suppl. Could these records again be evidence of the high adaptability of this species to secondary forest areas? They present almost no habitat limitation on occurrence, responding well to secondary forest, a predominant habitat in the CSP. Share this image — Hide sharing options. This study showed that the Callicebus nigrifrons population in CSP, a medium sized primate species with intermediate abundance in the primate community, is comparatively well established in this 7, ha forest reserve.

With regard to the vertical stratification observed, the titis exhibited a considerable preference for the lower canopy 10 to 14 meters class.
