1. Activity budget and social behavior of urban capuchin monkeys, Sapajus sp. (Primates: Cebidae)
ABSTRACT Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins

2. Tool use in urban populations of capuchin monkeys Sapajus spp. (Primates: Cebidae)
Capuchin monkeys, Sapajus Kerr, 1792, are known for their flexible behavior, including tool use, and their ability to survive in urban forests. We observed capuchin juveniles using wood as hammer and anvil and different materials as sponges (four tool-use events) in two geographically distinct urban populations in Brazil, in 2012: two in Goiânia, Central Br

3. Blank-comparison matching-to-sample reveals a false positive symmetry test in a capuchin monkey
A positive symmetry test result was obtained with a capuchin monkey that had previously exhibited virtually errorless AB and BA arbitrary matching-to-sample (MTS) with different stimuli. The symmetry test (BA) followed the acquisition of a new AB relation. It seemed possible, however, that the positive result could have occurred through the exclusion of prev

4. Curral de reses, Curral de almas: urbanização do sertão nordestino entre os séculos XVII e XIX / Cattle Corral, Soul\ s Corral: Urbanization of the Brazilian Northeasterner Hinterland between the 17th and 19th Centuries
Esta dissertação estuda a urbanização do sertão nordestino entre os séculos XVII e XIX, vinculada ao diálogo que chamamos de curral de reses e curral de almas. Curral de reses tece as questões do fenômeno urbano no interior do Nordeste açucareiro, no que dizia respeito ao papel exercido pela pecuária extensiva no povoamento, na posse da terra e no

5. Dieta y comportamiento alimentario de un grupo de mico maicero Cebus apella de acuerdo a la variación en la oferta de frutos y artrópodos, en la Amazonía colombiana
The relation between the abundance of fruits and arthropods, and the diet and feeding behavior of a group of Cebus apella was studied in the Colombian Amazon during 1999. Fruit availability was measured using phenological transects, and the abundance of arthropods by using manual captures. The abundance of both resources varied throughout the year, which all

6. Discrimination of complex visual stimuli in Cebus apella: identity matching with pictures
Do capuchin monkeys respond to photos as icons? Do they discriminate photos of capuchin monkeys' faces? Looking for answers to these questions we trained three capuchin monkeys in simple and conditional discrimination tasks and tested the discriminations when comparison stimuli were partially covered. Three capuchin monkeys experienced in simultaneous simple

7. Primates cognitive maps: analysis of movements and routes of Cebus nigritus based on geographic information system / Mapas cognitivos de primatas: análise de movimentos e rotas de Cebus nigritus apoiada por sistemas de informação geográfica
Capuchin monkeys are remarkable for their flexible foraging behavior, occupying environments with diverse characteristics, and, because of these elements they have the largest geographic distribution among the New World primates. They have skills such as tool use and spatial recognition of their home range when searching for food, relying on both egocentric

8. Memória relacional espacial e não-espacial associada ao forrageamento em macacos-prego (Cebus spp.) mantidos em cativeiro
Primates rely on spatial information to retrieve food resources. However, they might also rely on non-spatial representations of the environment to predict the location of resources and their seasonal availability. Therefore, the study was designed to assess spatial and non-spatial relational memory in capuchin monkeys (Cebus spp.). Compared with other New W

9. Interações sociais em grupos de macacos-prego (Cebus libidinosus) no Parque Nacional de Brasília
Primate social behaviour is influenced by different kinds of competition. Food competition is stronger among females because food intake limits female reproductive success. Thus, socio-ecological models are based mainly on food competition among females. In Cebus, females are philopatric and develop discriminative affiliative bonds and strong dominance relat

10. Interactions and conflicts between humans and Capuchin Monkeys (Cebus apella) in Children Park of Anápolis-GO. / Interações e conflitos entre humanos e macacos-prego (Cebus apella) no Parque da Criança em Anápolis-GO.
There has been an increase in the number of conflicts between Capuchin-monkeys (Cebus apella) and humans in municipal parks. Diminishing these conflicts has been a big challenge as it has to find permanent solutions that benefit both parts. In this study I investigated how the interactions between humans and capuchins occur, what people think about the prese

11. The monkey in the mirror: Hardly a stranger
It is widely assumed that monkeys see a stranger in the mirror, whereas apes and humans recognize themselves. In this study, we question the former assumption by using a detailed comparison of how monkeys respond to mirrors versus live individuals. Eight adult female and six adult male brown capuchin monkeys (Cebus apella) were exposed twice to three conditi
