| Ituglanis agreste, a new species of catfish, is described from a tributary stream of the rio Gongogi drainage, rio de Contas basin, Bahia State, northeastern Brazil, from a transition area between the Atlantic Rain Forest and the semi-arid Caatinga savanna. This species is distinguished from its congeners by the following characters: elongate interopercle plate with high number of odontodes (26-30), high number of ribs (5-6), fewer vertebrae (36), number of branchiostegal rays (7), number of pectoral-fin rays (i,6) and absence of s1 pore. Comparisons with other Ituglanis species and putative plesiomorphic characters are presented. Some comments about conservation of Ituglanis species from northeastern Brazil are also made. |

| Hollandichthys taramandahy, new species, is described from the rio Tramandaí, rio Mampituba, and rio Araranguá basins, coastal drainages of Rio Grande do Sul and Santa Catarina States, Brazil. The new species is distinguished from H. multifasciatus, the single recognized species of the genus, by the presence of a small black spot covering the base of median caudal-fin rays, by the lower number of dorsal and ventral procurrent caudal-fin rays, by the absence of a black spot located along anterior half of adipose-fin, and by the absence of humeral spot in specimens larger than 60 mm of standard length. Comments about the geographic distribution and diagnosis are provided for the genus. |

| O objetivo deste trabalho foi realizar o ajuste de modelos para estimar biomassa e carbono total de indivíduos de caixeta (Tabebuia cassinoides (Lam.) DC.), localizado em Guaratuba, litoral Paranaense, Brasil. Foram testados 13 modelos, e a escolha do melhor baseou-se nos indicadores estatísticos R2aj, Syx(%) e análise gráfica dos resíduos. Realizou-se ainda, como critério complementar de escolha, a avaliação das condicionantes de regressão dos resíduos dos melhores modelos. Não foram feitos ajustes de biomassa e carbono por compartimentos devido à baixa correlação entre as variáveis dependentes (biomassa e carbono) e independentes, diâmetro à altura do peito (dap) e altura total (h). Para a biomassa total, o modelo Y = β0 + β1*dap se mostrou superior aos... |

| Este trabalho teve por objetivo conhecer a fitossociologia do componente arboreo em uma mata ciliar de um corrego que desagua no Rio Sirinhaem, localizado no Engenho Buranhem, Sirinhaem, PE e identificar as sindromes de dispersao das especies. O corrego esta situado em um fragmento de Floresta Ombrofila Densa de Terras Baixas, com 272 ha. Utilizou-se como area amostral um hectare (40 unidades amostrais, 10 m x 25 m) onde foram registrados 1.307 individuos arboreos com circunferencia a altura do peito (CAP) ≥ 15 cm. Foram identificadas 118 especies, pertencentes a 40 familias botanicas. Protium heptaphyllum e Pouteria sp.1 foram as especies mais abundantes. Em termos de valor de importancia (VI), as especies Protium heptaphyllum, Pouteria sp.1 e Virola... |

| Plants of the genus Pinus are known worldwide by biological invasion potential. In the 1960s there were massive plantations of Pinus elliottii in the Campus of Juiz de Fora University, and nowadays the species is widespread. This study analyzed the species population structure in two distinct forest regeneration environments: open area (abandoned pasture) and closed-canopy (secondary forest) on the campus of UFJF, Juiz de Fora, MG, Brazil. The hypothesis were that the open environment would present a better structured population, due to the preference of species for open areas. Random plots were allocated (15 plots of 5 m x 5 m in each environment), and all individuals of the species (trees: dbh . 5 cm, saplings, dbh <5 cm and H . 1 m and seedlings: H... |

| The Rufous-nosed Mouse Wilfredomys oenax is a rare Sigmodontinae rodent known from scarce records from northern Uruguay and south and southeastern Brazil. This species is underrepresented in scientific collections and is currently classified as threathened, being considered extinct at Curitiba, Paraná, the only confirmed locality of the species at southeastern Brazil. Although specimens from São Paulo were already reported, the presence of this species in this state seems to have passed unnoticed in recent literature. Through detailed morphological analyzes of specimens cited in literature, the present work confirms and discusses the presence of this species in São Paulo state from a specimen collected more than 70 years ago. Recently, by the use of modern... |

| Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197... |

| We describe a new species of Atractus from Serra do Cipó, at the southeastern versant of Serra do Espinhaço, an inland mountain range nearly parallel to the Brazilian Atlantic coast. The new species is morphologically similar to A. paraguayensis and A. potschi with which it shares: 15 dorsal scale rows; white occipital region in juvenile specimens; dorsal ground color reddish pink to red (in life) with alternate black transversal spots, blotches or transversal bands; seven upper and lower labial scales; ventrals and subcaudals creamish white; hemipenis slightly bilobed, semicapitate and semicalyculate. The new species differs from both taxa mainly on the basis of exclusive coloration characters (number and shape of transversal bands) and hemipenial... |

| Abstract The genus Alterosa Blahnik (2005), with 39 extant species, is endemic to Atlantic Forest areas of southern and southeastern Brazil. Herein, we describe and illustrate two new species from Rio de Janeiro state, southeastern Brazil: Alterosa cornuta sp. nov., easily diagnosed by the horn-like intermediate appendages crossing each other, and A. araras sp. nov., recognized mainly by the extremely developed basodorsal protuberance on tergum X and by the rod-like, mesally curved preanal appendages, with at least 2 stout spine-like setae positioned at mid length and with the apex cupped. Additionally, a new distributional record for Espírito Santo state, southeastern Brazil, is provided for Alterosa falcata Blahnik (2005). |
