| Uma análise comparativa da riqueza de espécies de morcegos da Região Sul do Brasil é apresentada, assim como análises de similaridades entre estados. O estado do Paraná apresentou a maior riqueza de espécies de morcegos, com 64 espécies, seguido por Santa Catarina com 46 e pelo Rio Grande do Sul com 40. A família Phyllostomidae influencia fortemente este padrão de riqueza. As distribuições geográficas de Trachops cirrhosus (Spix, 1823), Artibeus cinereus (Gervais, 1851) e Thyroptera tricolor Spix, 1823 são ampliadas até o Paraná, estabelecendo um novo limite sul de distribuição dessas espécies e da família Thyropteridae. Além disso, Myotis dinellii Thomas, 1902 foi registrado pela primeira vez no Brasil, em Santa Catarina e no Rio Grande do Sul,... |

| A estrutura de comunidades de morcegos no Brasil ainda é pouco estudada e vêm sofrendo sérias modificações devido à perda de habitats. O principal objetivo do presente trabalho foi estudar a comunidade de morcegos da Estação Experimental de Itirapina, município de Itirapina, Estado de São Paulo. Nesta Estação, além das espécies cultivadas de Eucalyptus e Pinus, há diversas plantas que podem fornecer alimento aos morcegos. Entre julho de 2001 e julho de 2006, foram realizadas 58 sessões noturnas de captura de morcegos com 4 a 12 redes-de-neblina dispostas a cada sessão. Nesse período, foram capturados 720 indivíduos de 16 espécies de morcegos dos quais 13 pertencem à família Phyllostomidae, duas à Vespertilionidae e uma à Molossidae. A curva cumulativa de... |

| The microscopic characters of the hair can be used to indirectly identify species that are either uncommon or are difficult to see, for instance small Neotropical felids of the southern Brazilian Atlantic Forests. This widely used technique, which has not yet been standardized, involves the identification of hairs collected from feces. We tested the hypothesis that this tool is effective to identify four species of small Neotropical felids: Leopardus guttulus, Puma yagouaroundi, L. wiedii and L. pardalis. To accomplish that, we used measurements of the length, width and area of the cuticular scales in the guard hairs and calculated the relationship between width and length (quotient) for each species. A multiple discriminant analysis was conducted on the... |

| Investigating the Myotis levis complex is important for understanding the taxonomic status of the two subspecies currently recognized in it: Myotis levis levis (I. Geoffroy, 1824) and M. levis dinellii Thomas, 1902. Both M. levis levis and M. levis dinellii have been recently observed in sympatry in Argentina. This finding suggests that these populations might in fact correspond to distinct species rather than subspecies, as they have traditionally been designated. By using a multivariate morphometric approach, we demonstrate that M. l. levis has secondary sexual dimorphism in several measurements, with females being larger than males; sexual dimorphism was not detected in M. levis dinellii. However, we found morphometric differences between the two taxa.... |

| ABSTRACT The greater round-eared bat, Tonatia bidens (Spix, 1823), is a medium-sized phyllostomid bat distributed in the north of Argentina, Paraguay and Brazil. The diet and foraging patterns of this species are poorly known. We analyzed the composition of the diet of a population of T. bidens and how the temperature influences the consumption of vertebrates and invertebrates. To describe diet composition, we conducted weekly collections of food scrap from two monospecific night-perches. Data of temperature for the study period were taken from the meteorological station installed 300 m from the collection perches. The influence of temperature was evaluated using generalized linear models (GLMs) with negative binomial distribution. Tonatia bidens consumed... |

| Hair snares have been used in North and Central America for a long time in assessment and monitoring studies of several mammalian species. This method can provide a cheap, suitable, and efficient way to monitor mammals because it combines characteristics that are not present in most alternative techniques. However, despite their usefulness, hair snares are rarely used in other parts of the world. The aim of our study was to evaluate the effectiveness of hair snares and three scent lures (cinnamon, catnip, and vanilla) in the detection of felids in one of the largest remnants of the Brazilian Atlantic Forest. We performed tests with six captive felid species - Panthera onca (Linnaeus, 1758), Leopardus pardalis (Linnaeus, 1758), L. tigrinus (Schreber, 1775),... |

| Este trabalho relata um caso de tentativa de infanticídio por um macho residente e dominante de um grupo de Alouatta caraya (Humboldt, 1812) em um infante extra-grupo, em ilha do rio Paraná, Paraná, Brasil. O encontro do par fêmea-infante com o macho residente foi propiciado pela interferência humana. Devido às circunstâncias em que ocorreu o fato e a posição hierárquica do agressor, a hipótese de patologia social pareceu plausível na explicação do comportamento. |

| Howler monkeys (Alouatta Lacèpéde, 1799) are folivores-frugivores with flexible diets depending on conditions. Here, we compare the diets of Alouatta caraya (Humboldt, 1812) in two riparian forests (island and mainland), in Porto Rico region, Upper Paraná River, Southern Brazil. Howlers were followed from October 2004 to September 2005 in the riparian forest of a 1,050 ha island and in the continuous riparian forest on the mainland (left bank of the river). The "scan sampling" method with instantaneous samples every 15 minutes was used. Besides vines, diet breadth was similar: 17 species consumed on the island versus 16 species on the mainland. Both consumed leaves followed by fruits more than any other food type (leaves: island - 65%, mainland - 49%,... |

| This study was carried out at the Intervales State Park, an Atlantic Rain Forest area in Southeastern Brazil. Bats were monthly mist netted over a full year, and fecal samples were collected for dietary analysis. The seeds found in each sample were identified in the laboratory under a stereoscopic microscope by comparison with seeds taken from ripe fruits collected in the study area. Three hundred and seventy one bats were collected, of which 316 (85.2%) were frugivorous. The total number of fecal samples with seeds and/or pulp was 121. Sturnira lilium (E. Geoffroy, 1810) was the most abundant species in the study area (n = 157 captures) and Solanaceae fruits accounted for 78.5% of the fecal samples with seeds (n = 56).

| 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... |

| Prey foraging behavior in the Black Lion Tamarin, Leontopithecus chrysopygus (Mikan, 1823) was observed in the Caetetus Ecological Station, southeastern Brazil, during 550 hours of direct observations between December 1993 and February 1995. The scan sampling method was used to gather data. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats. The most important microhabitat used for prey foraging behavior was tree cavities (41% of the foraging observations), but palm trees (22%), bamboo (12%), vines (11%), bark (5%), seed pods of the "jequitiba" tree (4%), other places (3%) and epiphytes (2%) were also observed. Animal preys were frequently captured in understory... |

| 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 region of Porto Rico, on the Upper Paraná River, is a contact zone between the Atlantic Rainforest and the Cerrado, with elements of the Pantanal wetlands. During surveys from September 2003 to September to 2005, we recorded the presence of non-volant mammals on 14 islands and the adjacent riverbanks. Surveys were by foot and by boat, and we also interviewed local people about the mammals of the region. Sightings of three primate species - Cebus nigritus (Goldfuss, 1809) (left margin of the river), C. libidinosus Spix, 1823 (right margin) and Alouatta caraya (Humboldt, 1812) (both margins and 12 islands) - were plotted on a satellite image. Alouatta clamitans Cabrera, 1940 was not recorded. However, interviews indicated that this species has occurred... |

| 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,... |
