| The phytal is characterized by the formation of seaweed beds and a great diversity of associated species, the malacofauna being one of its main components. Aiming to record the species of Gastropoda associated to the brown algae Sargassum sp. C. Agardh, 1820, this study was carried out in São Sebastião Channel, northern coast of São Paulo, and nearby areas. A total of 13945 individuals were identified, belonging to 35 families and 62 species. Cerithiidae, Phasianellidae and Columbellidae were the most abundant families, represented by 34, 33 and 17% of the total collected individuals, respectively. Bittiolum varium (Pfeiffer, 1840) (Cerithiidae) and Eulithidium affine (C. B. Adams, 1850) (Phasianellidae) are the dominant species, followed by the... |

| Este trabalho descreve variações morfológicas nos órgãos e estruturas do aparelho reprodutor masculino em Chaunus ornatus, analisados independentemente das alterações promotoras de variações estruturais. Foram utilizados sete exemplares adultos da espécie, coletados no Município de Botucatu (São Paulo, Brazil) na época de atividade reprodutiva. Os espécimes foram dissecados e medidas do comprimento rostro-cloacal, análises anatômicas descritivas e biométricas foram obtidas. Três destes animais foram encaminhados à rotina histológica para a análise da arquitetura testicular e esquematizada em papel vegetal com caneta nanquim. Análises estatísticas (média, desvio-padrão, teste de Shapiro-Wilk, teste t de Student e Regressão Linear Simples) foram empregadas... |

| Estudos fenológicos são importantes para o entendimento da dinâmica dos ecossistemas florestais, principalmente quando avaliam a disponibilidade de frutos para a fauna. As matas ciliares são formações vegetais que ocorrem ao longo dos cursos d'água e desempenham papel importante na formação dos corredores de fluxo gênico, podendo interligar populações vegetais que foram separadas pelo processo de fragmentação. O presente trabalho procurou entender como varia a fenologia reprodutiva e a disponibilidade de frutos de espécies arbóreas em mata ciliar do rio Formoso, município de Bonito, Mato Grosso do Sul, entre estações e ao longo de um ano. Foram feitas observações mensais em 29 espécies vegetais, 31% anemocóricas e 68,9% zoocóricas, das fenofases floração e... |

| The Neotropical otter Lontra longicaudis (Olfers, 1818) (Carnivora: Mustelidae) is a semi-aquatic species spread throughout Central and South America, except Chile. It uses cavities on the river banks or spaces amidst dense vegetation as shelter and defecates in conspicuous places as a means of territorial marking. The study was conducted between April 2008 and March 2009, aiming to compare and correlate the frequency of shelter use and marking by the otters, considering vertical vegetation cover, height, distance, disturbance degree and type of structure/substrate factors, in a lotic environment (Sapé stream, São Paulo state, Brazil) and a semi-lotic environment (Canoas I hydroelectric reservoir, Paranapanema Valley, São Paulo and Paraná states, also in... |

| Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for the Reserva Ecológica de Guapiaçu (REGUA), a forest reserve located in the central portion of Rio de Janeiro state, Brazil. The list results from an extensive sampling effort that lasted ten years. A total of 73 amphibian (of which ten are endemic to the state) and 37 reptile species was recorded from the area. Five amphibian species are presently categorized by the IUCN as “data-deficient”, two as “near threatened” and one as “endangered”, whereas one reptile species is categorized as “vulnerable”. Our results showed that REGUA harbors about... |

| Previous records of the callianassid ghost shrimps Biffarius biformis (Biffar, 1971) and Biffarius fragilis (Biffar, 1970) from Pernambuco, northeastern Brazil, were considered as doubtful, because their original record (Carvalho et al. 1997) in a conference abstract cannot be considered as a valid publication. The original material examined by Carvalho et al. (1997) combined with the more recently collected material of B. biformis and B. fragilis, confirm the presence of these two species in Brazil and the southwestern Atlantic. Taxonomic and ecological remarks, as well as illustrations, are provided for both species. |

| The watershed of the São Francisco River is a large complex of headwaters of the Paraguay River, the main river of the Pantanal Matogrossense. Considering that Fabaceae are pointed out as the main family in floristic composition of various Brazilian biomes, however in some regions of Brazil is still little known upon the taxa, particularly in the Northern part of the Central-West, this study aimed to present a list of taxa occurring in the sub-basin of the São Francisco River, municipality of Nova Marilândia, State of Mato Grosso. For the taxa we give information on habit, vegetation, data on geographic distribution, potential use, successional strategy and dispersal syndrome, to subsidize habitat restoration projects. We recorded a total of 44 taxa,... |

| The northern part of the state of Rio Grande do Sul was extensively deforested in recent decades, and only isolated fragments of the original vegetation remain. The Parque Natural Municipal de Sertão comprises a remnant of Atlantic Rain Forest, one of the largest fragments in northern Rio Grande do Sul. This study examined the diversity of the herpetofauna, focusing on environmental distribution, seasonality and species richness. We used complementary methods of sampling such as pitfall traps, active search and occasional encounters. We recorded 23 species of frogs, nine snakes and one lizard. With respect to the relationship between amphibians and reptiles and the structural and abiotic factors of the environment, the edge of the fragment showed higher... |

| Com o objetivo de contribuir com o conhecimento das borboletas de Curitiba, foram estudados dois parques municipais urbanos, o Jardim Botânico que possui área total de 178.000 m² e um bosque de Floresta Ombrófila Mista preservada restrito a pesquisa científica, e o Parque Municipal da Barreirinha que possui uma área total de 275.380 m² e a área utilizada para as amostragens de livre acesso a população, com predominância de vegetação reflorestada. Após 10 meses de amostragem, perfazendo 240 horas, foram registrados 787 indivíduos e 166 espécies, distribuídos nas famílias: Hesperiidae - 46 spp. (27,7%), Nymphalidae - 75 spp. (45,2%), Pieridae - 17 spp. (10,3%), Lycaenidae - 13 spp. (7,8%), Papilionidae - 8 spp. (4,8%) e Riodinidae - 7 spp. (4,2%), dentre... |
