| Cerdocyon thous (Linnaeus, 1766) is the most widespread neotropical canid, most commonly inhabiting forested areas. This animal is a generalist omnivore that is able to use environments disturbed by human activities. The aim of this study was to describe its diet through the stomach content analysis of 30 samples obtained from specimens that were run over in a mosaic composed by Araucaria Pine Forest, Semidecidual Seasonal Forest, natural grasslands, and exotic vegetation. The items were quantified by frequency of occurrence (F.O.) and percentage of occurrence (P.O.). A total of 64 food items were found among 171 occurrences. According to F.O. method, plant items corresponded to 93.3% of the occurrences, followed by animal items (86.7%) and human rejects... |

| This study was carried out in the Chácara Payquerê do Bugre, State of Paraná, Southern Brazil (25º29'52" S and 49º39'24" W) and reports on the demography of a group of Alouatta guariba clamitans Cabrera, 1940 followed monthly during three years (from February, 2002 to March, 2005). The growth and subsequent fission of the group are described and argued, as well as their possible underlying causes, focusing on the population ecology and social behavior of this taxa. |

| Observações diretas do comportamento de beber água por espécies de Alouatta Lacépède, 1799 são incomuns em animais de vida livre. Foram reportadas flutuações sazonais na freqüência do consumo de água, as quais foram relacionadas à disponibilidade dos diferentes itens alimentares no ambiente. O objetivo deste trabalho foi quantificar os registros do consumo de água por um grupo de Alouatta clamitans Cabrera, 1940, bem como analisar suas variações sazonais, circadianas e sexo-etárias. O consumo de água foi relacionado aos períodos de alimentação ao longo do dia. Houve correlação entre consumo de água e ingestão de sementes. A análise sexo-etária demonstrou que as fêmeas adultas ingeriram proporcionalmente mais água, enquanto infantes consumiram menos.... |

| The development of the interactions of an infant primate with its mother and the other members of its social group plays a special role in the ethology and demography of the species, with consequences for their survive and their conservation. The objective of the present study is to investigate the development of an infant of Alouatta guariba (Humboldt, 1812) in the wild, its behavior and interactions during its first seven months of age, in a remnant of Araucaria Pine Forest in Paraná State, Brazil. Using the method of instantaneous scanning with 5 min intervals, a total of 46 hours and 15 minutes of direct observation (555 individual records) showed that the infant behavioral patterns during its first four months were characterized by high dependency,... |
