| There are few studies on the zooplankton from the northwestern region of São Paulo State, Brazil, compared to other regions of the State. Cladocerans are a very representative zooplankton group with high species diversity. Most of this diversity can be found at littoral zones of lakes and reservoirs, especially those occupied by macrophytes. This study was part of a thematic project FAPESP/BIOTA Program - The Virtual Institute of Biodiversity (www.biotasp.org.br), and its aim is to catalogue and analyze the distribution of cladoceran species (Crustacea, Anomopoda and Ctenopoda) in pelagic and littoral zones from small reservoirs in the northwest of the São Paulo State, in dry and rainy seasons. Zooplankton samplings were carried out in littoral and pelagic... |

| The objective of the present study was to evaluate the effects of light and temperature on germination of Cereus pernambucensis seeds, a species of columnar cactus native to Brazil and naturally incident in the restinga. Cereus pernambucensis seeds were incubated under different temperatures, from 5 to 45 °C, with 5 °C intervals, and under alternating temperatures of 15-20 °C, 15-30 °C, 20-25 °C, 20-30 °C, 20-35 °C, 25-30 °C, 25-35 °C, and 30-35 °C, both under continuous white light and dark. The seeds were also incubated in a gradient of phytochrome photoequilibrium at 25 °C. The highest percentage germination in this species was between 25 and 30 °C. The minimum temperature was between 15 and 20 °C and the maximum between 35 and 40 °C. Alternating... |

| In the state of Mato Grosso, studies aiming to investigate the diversity and richness of bats are still scarce. In the present study, the chiropteran fauna of eastern Mato Grosso (Brazil) was investigated at four sites representing the Cerrado savanna biome with different degrees of anthropogenic impact, in the municipality of Nova Xavantina. Surveys were conducted between January and December, 2010, with a total of 48 nights of mist-netting. A total of 423 bats were captured, representing 25 species distributed in five families. A greater abundance of individuals was recorded at all sites during the rainy season, with considerable variation being observed over the course of the year in species richness and composition, and the abundance of bats. Species... |

| Os levantamentos biológicos realizados nos últimos cinco anos na Reserva Florestal do Morro Grande (RFMG) permitiram inventariar mais de 13.000 indivíduos pertencentes a 673 espécies de árvores, mamíferos não-voadores, aves, répteis, anuros e aranhas orbitelas. A comparação dos dados obtidos revela padrões biológicos consistentes que levam a quatro conclusões principais: i) a RFMG se situa numa condição de transição, recebendo influências das florestas ombrófilas densas e mistas, das estacionais e até do cerrado; ii) todos os grupos taxonômicos estudados apresentam diferenças significativas na riqueza e/ou na composição de espécies quando comparadas as florestas em estádios sucessionais intermediários/avançados de sucessão (80-90 anos após corte raso) e a... |

| This study aimed to evaluate population abundance patterns and the main events in the reproductive cycle of Loricariichthys platymetopon at Saraiva Lagoon, Ilha Grande National Park, MS-PR, Brazil. Monthly samplings were conducted from October 2004 to September 2005 in three sections of the lagoon: entrance, middle and end, which resulted in the capture of 175 individuals. Spatial and temporal variation in abundance was obtained through CPUE (number of captured individuals/1000 m² of gillnets in 12 hours). The reproductive tactics considered were: duration, time and location of spawning, oocyte diameter and fecundity. The highest relative abundance was recorded in February, in the middle section of the lagoon, and the reproductive period lasted from... |

| This study reveals the food composition of pelagic fishes living in the southwestern Atlantic Ocean. As such more common pelagic species are considered to be top predators, the study proposes to know what constitutes their main food. Fish are not commonly found within their stomach contents, but instead, cephalopods are their most common food. As can be observed, Teuthida cephalopods compose their principal diet. The stomach contents of specimens of Xiphias gladius, Thunnus albacares, T. obesus, T. alalunga, Isurus oxyrinchus and Alopias superciliosus caught during July 2007 to June 2009 by using tuna longliners were studied. Teuthida cephalopods constitute the main food item for the three tuna species, while X. gladius feeds mainly on Ommastrephidae... |

| The endemic Neotropical long-horned caddisfly subgenus Notalina (Neonotalina) Holzenthal contains nine described species in two species groups, the brasiliana and roraima groups, from the Brazilian Southeastern and Amazonian regions, respectively. In this paper, a new species of Notalina in the brasiliana species group, from Chapada dos Veadeiros National Park, Goiás state, Brazil, is described and illustrated. The new species is easily recognized by the following character set: presence of two pairs of processes on abdominal segment X; presence of well-developed basoventral protuberances, mesally directed in ventral view; presence of triangle-shaped, acuminated mesoventral process on the inferior appendages; and phallic apparatus with flanges slightly... |

| Apesar da riqueza e abundância de Syrphidae na Região Neotropical, a literatura sobre a família nessa Região é relativamente escassa. A identificação de espécimes pertencentes a Syrphidae e, em especial, à subfamília Syrphinae, torna-se muitas vezes difícil pelo fato desse grupo possuir grande variação morfológica entre as espécies de um mesmo gênero. Com o propósito de auxiliar a identificação do grupo é apresentada uma chave ilustrada para as subfamílias Eristalinae, Microdontinae e Syrphinae e para os gêneros de Syrphinae com ocorrência nos estados do Rio Grande do Sul, Santa Catarina e Paraná, região Sul do Brasil. Espécies de onze gêneros têm sido registradas para a região: Allograpta Osten Sacken, Argentinomyia Lynch Arribálzaga, Leucopodella Hull,... |

| The Brazilian Pantanal comprises a mosaic of forest and field environments harbouring a rich community of large and midsized mammals that are adapted to the annual hydrological cycle. Here we evaluated richness and composition of large and midsized mammals inhabiting forested and open habitats affected by yearly floods in the Pantanal in Cáceres from October 2009 to September 2010. We compared these communities in marshes, dry forests and riparian forests based on 640 camera-traps.nights, sights, tracks, faecal samples and interviews. We also compared results in a private land (Descalvados Farm) and in a protected area (Taiamã Ecological Station). In total, we sampled 26 large and midsized mammals, including five threatened and two near threatened species.... |

| In the Cerrado, veredas are linear physiognomies that occur on hydromorphic soil usually along narrow water courses. They often growth on flat terrain or near headwaters. They are characterised by the abundance of buriti palms (Mauritia flexuosa) that growth over other trees, numerous shrubs and a dense herbaceous stratum. Despite being common landscape elements through the Cerrado's extension, the use of veredas by birds has not been examined in detail. This study aimed to review studies of birds and veredas in the Cerrado. Publications (n = 25) reported the use of veredas by 261 bird species. Only 13 of them had aspects of their biology (reproduction and feeding) studied in detail. Veredas are poorly used by Cerrado's endemic species, but are the major... |

| O Filo Entoprocta compreende cerca de 180 espécies de metazoários aquáticos e sésseis, na grande maioria marinho. Esses animais são encontrados em substratos diversos, incluindo seixos, algas, conchas e outros animais. Apesar da semelhança com outros organismos coloniais, como hidrozoários e briozoários, os entoproctos são distintos pelo corpo constituído por um cálice distal com tentáculos ciliados, sustentado por um pedúnculo fixo no substrato através do pé ou estolão. A relação do grupo é bastante obscura, e estudos taxonômicos e morfológicos são escassos em todo mundo. Devido sobretudo ao trabalho de Ernest Marcus e Eveline Du Bois-Reymond-Marcus, realizado entre as décadas de 1930 e 1970, são conhecidas 18 espécies na costa brasileira, 16 das quais... |

| Abstract: We present here an embracing freshwater fish inventory of the Parque Nacional dos Lençóis Maranhenses and adjacent areas, reporting 49 fish species, 33 of which were identified accurately at the species level, representing ten orders and 25 fish families that range from obligate freshwater to estuarine organisms. This number of species is much larger than two previous studies for the park, each reporting just 12 and 33 fishes occurring on freshwater environments. Among the 49 freshwater species recorded in this study, 14 are new records for the Parque Nacional dos Lençóis Maranhenses, and just one corresponds to an introduced species. Some of the 14 new records in the Parque... |

| Information on the role of smooth-billed anis (Crotophaga ani) as tick-pickers on mammals remains controversial. I record here these birds removing ticks and pecking at wounds of capybaras (Hydrochoerus hydrochaeris) in a small reserve at Campinas, São Paulo, southeastern Brazil. The birds inspected the mammals skin, both in places with and without hair. The hair was parted with bill movements, and ticks were removed by vigorous pulling. The birds also pecked at open or healing sores, from which they extracted small portions of blood clots and dead tissue. The capybaras appeared oblivious to the birds activity. Even in the case that the cleaning behaviour is restricted to some bird individuals and populations, or places and periods, this record validates... |
