Anthropogenic habitat fragmentation is a chronic problem throughout the Brazilian Atlantic Forest biome. In the present study, four forest fragments of 60-120 ha were surveyed on a rural property in southern Sergipe, where two endangered primate species, Callicebus coimbrai Kobayashi & Langguth, 1999 and Cebus xanthosternos Wied-Neuwied, 1826, are found. Two transects were established in each fragment, and the predominant habitat in 50 m sectors was assigned to one of three categories (mature forest, secondary forest and anthropogenic forest). Standard line transect surveys of the resident primate populations - which included a third species, Callitrhix jacchus Linnaeus, 1758 - were conducted, with a total of 476 km walked transect, resulting in 164 primate sightings. At each sighting of a primate, the habitat class was recorded and the height of the individual above the ground was estimated. The analysis indicated a significant (p < 0.05) preference for mature forest in C. xanthosternos which was also observed more frequently in the larger and better preserved fragments. No clear habitat preference was verified in the other two species, although both were relatively more abundant in the smaller fragments. However, a tendency to avoid anthropogenic forest was observed in C. coimbrai. Callitrhix jacchus used significantly lower (p < 0.05) forest strata than the other species, although other differences were unclear, presumably because of the reduced stature of the forest in the fragments. Overall, the results of the study indicate that C. xanthosternos is tolerant of the effects of habitat fragmentation, and that differential habitat use may play an important role in niche partitioning

“…Although a group containing only two individuals may seem small and atypical, groups of two to three individuals are, in fact, common for Callicebus in general (Ferrari et al 2000;Norconk 2007;Trevelin et al 2007). …”

Most aspects of the ecology and behavior of Callicebus nigrifrons are still unknown. The information available about this species is mainly based on a few studies that also focused on other Callicebus. We examined the feeding behavior and activity pattern of a free-ranging pair of C. nigrifrons between March and November 2007 in an area of semideciduous tropical forest of southeastern Brazil. The study site is located at the southern limit of the Tropical Zone and is characterized by pronounced seasonality. As observed for other Callicebus monkeys, fruits were the most consumed food resource, accounting for 53% of the diet, which was complemented mainly by leaves (16%) but also by invertebrates and flowers (10% of each). A great variety of plant families (28) and species (62) were included in the diet. The titis spent 35% of their time feeding, distributing the remaining time between resting (30%) and traveling (24%). Data presented here indicate that C. nigrifrons prefer high-quality food items (fruit pulp), adding low-quality food items (such as leaves) as the availability of the higher-quality foods decreases. The amount of time spent traveling and resting did not change between seasons, but the time invested in feeding increased during the lean period. The activity pattern was not related to fruit availability, but in months with lower temperatures, monkeys spent more time feeding. We suggest that the feeding ecology and activity pattern of C. nigrifrons reflect adaptations related to annual fluctuations in food availability and temperature, respectively.

“…While some ecological data are available for the other Atlantic Forest titis (Müller, 1996;Neri, 1997;Price and Piedade, 2001;Heiduck, 2002;Oliveira et al, 2003;Trevelin et al, 2007), it may be premature to assume that C. coimbrai will be similar to these species, especially considering that it is restricted to the northernmost extreme of the genus' distribution in the Atlantic Forest, where the biome is reduced to a relatively narrow coastal strip. However, in the first ecological study of C. coimbrai, Souza-Alves (2010) recorded ecological patterns similar to those of other Atlantic Forest titis.…”

The recently-discovered titi, Callicebus coimbrai, is endemic to the coastal Brazilian Atlantic Forest south of the São Francisco River, a region with a long tradition of deforestation. While a number of C. coimbrai populations have now been identified, little is known about basic population parameters. Considering the importance of this information for conservation planning, the population of a site in southern Sergipe (with a total area of forest of approximately 500 ha) was surveyed between April and October 2008. Standard line transect procedures were used in the four largest fragments, and additional monitoring included the use of playback broadcasts for the observation of titi groups. The presence of titis was confirmed in all the forest fragments at the site, including one of only five hectares. Two other primatesCallithrix jacchus and Cebus xanthosternos -were also recorded at the site, but were less abundant than titis. A total transect walk of 476 km provided 164 sightings of primates, the majority of which (104) were of Callicebus coimbrai. Titi groups ranged in size between two and five individuals. The most reliable estimate of overall population density, derived from the combined data set, was 12.6 individuals per km², although density was much higher in smaller (more disturbed) fragments. The total population of Callicebus coimbrai at the site was estimated to be at least 50 individuals, which may represent a considerable proportion of the population of the species remaining in the wild. In addition to its apparent tolerance of habitat fragmentation, densities of C. coimbrai recorded at the site compare favourably with those of other Atlantic Forest titi species.Keywords: Callicebus coimbrai, Brazilian Atlantic Forest, habitat fragmentation, population density, conservation. Parâmetros populacionais do guigó ameaçado, Callicebus coimbrai Kobayashi andLangguth, 1999, na paisagem fragmentada do sul de Sergipe, BrasilResumo O guigó-de-Coimbra-Filho recém descoberto, Callicebus coimbrai, é endêmico da Mata Atlântica do litoral brasileiro ao sul do rio São Francisco, uma região marcada pelo desmatamento. Enquanto um número de populações de C. coimbrai já foram identificadas, pouco se sabe sobre os parâmetros populacionais básicos. Considerando a importância dessas informações para o planejamento da conservação, foi feito um levantamento da população de um local no sul de Sergipe (com uma área total de floresta de cerca de 500 ha) entre abril e outubro de 2008. Procedimentos de transecção linear foram utilizados nos quatro maiores fragmentos e monitoramento adicional incluiu o uso da técnica de playback para a observação de grupos de guigós. A presença de guigós foi confirmada em todos os fragmentos de floresta no local, incluindo um de apenas cinco hectares. Outros dois primatas -Callithrix jacchus e Cebus xanthosternos -também foram registrados no local, mas foram menos abundantes do que o guigó-de-Coimbra-Filho. Um total de 476 km percorridos proveram 164 avistamentos de primatas, a maioria (...
