| Studies on floristic and structural variations of forests in relation to altitude have contributed to the knowledge of patterns and causes of spatial distribution of plants in the Atlantic Forest. Geographical variables such as latitude, longitude and altitude result in different vegetation types, which limits newly established are not consensus. In the north coast of São Paulo state altitudes vary from the Restinga Forest, near the sea level, to the vegetation at the top of Cuscuzeiro Mountain at 1,279 m altitude. In order to evaluate the richness, taxonomic diversity, floristic similarity and the potential indicator of Leguminosae in the characterization of different vegetation types of Atlantic Forest on the northern coast of São Paulo, a matrix with... |

| Scinax aromothyella is a recently described hylid frog. Its distribution is not well known. There are records for Misiones, Argentina and for southeastern Uruguay. Here we report a new record of S. aromothyella from Aceguá, Cerro Largo Department, Uruguay (31° 53' 39" S and 54° 9' 17" W), based in tadpoles collected on the 15 of August, 2007. This new record extends the distribution of S. aromothyella in approximately 100 km north from previous reports in Uruguay. The samples were collected in a site located 2 km away from the border line with Brazil, reinforcing the idea that S. aromothyella might occur in Rio Grande do Sul. |

| The risks following introduction of invasive species are enormous and incalculable. Achatina fulica is considered one of the 100 species of greatest invasive potential, stands out among the land pulmonate snails, mostly for its high reproductive potential that accelerates the process of dispersion, increasing the damages related to health (disease transmission), to economy (crops destruction) and to environment (biodiversity loss). In order to investigate the relationship of the African snail with the environment, trying to relate sexual activity with climatic variables (temperature, rainfall and humidity), a study was conducted on aspects of population dynamics and reproductive biology in Salvador city. The snails were collected by hand, monthly.... |

| Este trabalho teve como objetivo registrar as espécies de ácaros que ocorrem em frutíferas e outras plantas de importância econômica no Estado do Amapá. O levantamento foi realizado nos municípios de Macapá e Calçoene. Nove espécies de plantas pertencentes a sete famílias foram estudadas, tendo sido identificados 226 espécimes de ácaros, das famílias Ascidae, Phytoseiidae, Cunaxidae, Eriophyidae, Stigmaeidae, Tarsonemidae, Tenuipalpidae, Tetranychidae e Tydeidae. A família Tetranychidae apresentou cinco espécies, tendo sido a de maior riqueza. |

| In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 taxa. Our results show that macroinvertebrate communities, at genus as well as family level, are in concordance to a priori classifications that distinguish between white and clear water streams. The main implication of our results for biomonitoring... |

| Na Amazônia brasileira a pesca é importante fonte de renda e proteína animal para as populações ribeirinhas. E, entre as espécies de peixes de maior volume desembarcado nos mercados e feiras da região se destacam as sardinhas, Triportheus albus, T. angulatus e T. auritus. Considerando o aumento da pressão pesqueira, que gera a redução de alguns estoques pesqueiros na região, tanto na quantidade como no tamanho de algumas espécies, o trabalho propõe determinar os parâmetros de crescimento, mortalidade e relação peso-comprimento dessas espécies em lagos de várzea, Manacapuru, AM. Os parâmetros foram estimados através da análise de distribuição de frequência de comprimento com o auxílio da rotina "scan de valores de k" do método ELEFAN I do programa FISAT II.... |

| Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following... |

| A survey for freshwater gastropods carrying trematodes parasites was conducted in Manso Dam and the surrounding areas frequented by tourist, focusing particularly on the Pantanal region. Infected snails were recovered from twelve of the eighteen investigated municipalities and forty-one cercaria-snail pairings were recorded. Among these pairings were several first records of snails serving as intermediate hosts for trematodes in Brazil including Biomphalaria amazônica Paraense, 1966, Biomphalaria occidentalis Paraense, 1981, Marisa planogyra Pilsbry, 1933, Pomacea maculata Perry, 1830, Pomacea scalaris (d'Orbigny, 1835) and Gundlachia radiata (Guilding, 1828). Echinostomatidae and Strigeidae were the most common trematode families (ca. 47%) and the... |

| Abstract: The state of Paraná, located in southern Brazil, was originally covered almost entirely by the Atlantic Forest biome, with some areas of Cerrado savanna. In the present day, little of this natural vegetation remains, mostly remnants of Atlantic Forest located in the coastal zone. While some data are available on the anurans of the state of Paraná, no complete list has yet been published, which may hamper the understanding of its potential anuran diversity and limit the development of adequate conservation measures. To rectify this situation, we elaborated a list of the anuran species that occur in state of Paraná, based on records obtained from published sources. We recorded a total of 137 anuran species, distributed in 13 families. Nineteen of... |

| A riqueza de espécies, o uso de habitat e a identificação das principais ameaças sobre uma taxocenose de anfíbios anuros foram determinadas ao longo de 19 meses, em uma localidade originalmente coberta de Floresta Ombrófila Densa no município de Morretes, Paraná, Brasil. Foram registradas 32 espécies de anuros pertencentes a 10 famílias. A anurofauna local apresenta 58% das espécies associadas à ambientes de área aberta e 42% associadas à ambientes florestais. Dentre todos os modos reprodutivos registrados, o modo tipo um - ovos e larvas exotróficas em habitats lênticos, foi o mais comum, especialmente em Hylidae. A atividade de desmatamento, que atualmente é umas das causas de maior efeito negativo sobre populações de anfíbios, ocorre a pelo menos 28 anos... |
