“…Riparian forest along the river in Mato Grosso do Sul is a narrow corridor and with a relatively small area for foraging. In contrast, S. nigritus is more abundant on the Paraná side of the river than is typical (Ludwig et al, 2005;Martins, 2005;Almeida-Silva et al, 2005). On the Paraná side, the riparian forest corridor is wider, with more mature and better-preserved forest including many palm trees where they forage, as well has having cultivated crops that they may also consume (Ludwig et al, 2005).…”

“…We suggest that the interactions of density compensation, crowding, low hunting and predation pressures, and the extremely abundant Cecropia (for howlers) probably allow the unusually high densities. Although humans have fragmented the habitat, primates are still relatively abundant, which suggests that these are important populations for conservation, in contrast with the lower abundances of these species elsewhere (Ludwig et al, 2005;Moura, 2007).…”

“…For example, in the Amazon, small and mediumsized primate species increase in abundance where larger species of the family Atelidae are preferentially hunted (Peres and Dolman, 2000). Also, greater densities in Alouatta and Sapajus species may be found in degraded communities in fragments and islands (Chiarello and Galetti 1994;González-Solís et al, 2001;Ludwig et al, 2005;Martins, 2005;Almeida-Silva et al, 2005;Link et al, 2010).…”

Three primates (Alouatta caraya, Sapajus nigritus and Sapajus cay) are found in riparian areas of the Upper Paraná River in southern Brazil. Population densities of these three species were estimated from October 2004 through September 2005 by counts on linear transects in riparian forests on two riverine islands and adjacent shores in the states of Mato Grosso do Sul and Paraná. A total of 397 sightings of these species were accumulated in 188 km of traversed transects. Alouatta caraya was the most abundant species on the large island (2.56 ind ha-1) and on the Mato Grosso do Sul side (0.84 ind ha-1). This density was greater than twice that of the sympatric S. cay (0.31 ind ha-1). Sapajus nigritus was the most abundant species on the Paraná side (0.51 ind ha-1) followed by A. caraya (0.40 ind ha-1). The folivorous A. caraya was the most abundant in flooded forests, while the omnivorous Sapajus species were less so. Differences in forests, conservation status, dispersal restrictions and autecology of the primates help explain differences in primate abundance.

Resumo AbstractThe objective of this study was to describe the behavior of Cebus nigritus kept in captivity. The work, carried out during the month of March 2008 at "Dr. Belírio Guimarães Brandão" County Zoo in Garça-SP and Monte Alegre Farm Ecological Park in Telêmaco Borba-PR, included 48 hours of observations, divided equally in four daytime periods. The behavioral catalogue used was constituted of different categories such as: foraging, feeding, locomotion, rest, social interaction, physical care, alertness, manipulation of things, reproductive behavior and stereotyped behavior. Animals showed activities of foraging, feeding, and locomotion and social interaction in low percentages in the two morning periods; however, their frequencies increased in the afternoon. Other activities like physical care, alertness and stereotyped behavior appeared mainly in the two morning periods, but were reduced in the afternoon. The rest category was more evident early morning and late afternoon. Since the stereotypical behavior presented high percentages, this study recommends that the number of individuals be diversified in the social organization of the groups and that environment enriching activities be developed in captivity, creating situations similar to the animal's natural habitat.

Capuchins are omnivorous neotropical primates that can survive in urban forests by supplementing their diet with human foods. However, few studies have analyzed the impact of these resources on their diet diversity and feeding seasonality. We aimed to assess the patterns of foraging, feeding, and diet diversity of urban capuchins (Sapajus sp.) that live in a tiny urban forest in Foz do Iguaçu, Brazil, where humans frequently feed them. We predicted that forest degradation and human foods could decrease diet diversity, though capuchins may, conversely, reduce their selectivity and expand their food repertoire. We followed the animals from dawn to dusk between May 2018 and April 2019 to list and quantify the species and items consumed. We used diversity indexes and cluster analysis to understand similarities and differences in the diet composition over the study period. We recorded 58 plant species (being 14 exotics) consumed by the monkeys, and nonconventional items, with low diet diversity overall. The diet consisted mainly of plants (69.8%), animal matter (20.6%), and processed foods (9.5%). Capuchins consumed more food from the anthropic environment (57.5%) than from the forest (42.4%), while their food from the forest included more invertebrates (47.8%) than fruits (40%). The cluster analysis showed two main groups of feeding months, in accordance with the seasons of high and low food production in local forests. Monkeys did not vary the frequencies of foraging or feeding between seasons, probably due to the omnipresent availability of human foods. Despite the high consumption of human foods, capuchins responded to the seasonality of the forest, expanding their feeding diversity in the drier period. Future studies should analyze the correspondence between food consumption and local phenology, as well as the potential role of capuchins as seed dispersers in this depauperate community.
