| Listrura costai, new species, is described from small streams in a swampy coastal plain in the rio Jurumirim basin, Angra dos Reis Municipality, Rio de Janeiro State, southeastern Brazil. The new species is morphologically very similar to L. nematopteryx and L. picinguabae, all possessing only one long pectoral-fin ray. It differs from its congeners by possessing an autapomorphic character: first hypobranchial with an anterior process (vs. process absent). Other features such as coloration, numbers of opercular and interopercular odontodes, number of anal-fin rays, head length, and shape of some bone structures help to distinguish the new species from L. nematopteryx and L. picinguabae. Molecular analyses using partial sequences of the mitochondrial DNA... |

| Assessing the composition of an area's bat fauna is typically accomplished by using captures or by monitoring echolocation calls with bat detectors. The two methods may not provide the same data regarding species composition. Mist nets and harp traps may be biased towards sampling low flying species, and bat detectors biased towards detecting high intensity echolocators. A comparison of the bat fauna of Fazenda Intervales, southeastern Brazil, as revealed by mist nets and harp trap captures, checking roosts and by monitoring echolocation calls of flying bats illustrates this point. A total of 17 species of bats was sampled. Fourteen bat species were captured and the echolocation calls of 12 species were recorded, three of them not revealed by mist nets or... |

| O presente trabalho trata do estudo florístico da vegetação arbórea que ocorre ao longo de um trecho das margens do rio da Fazenda, localizado no Parque Estadual da Serra do Mar, Núcleo de Picinguaba, no litoral norte do estado de São Paulo, município de Ubatuba (44°48' W e 23°22' S). Para a realização do levantamento, foram alocadas 40 parcelas de 10 m x 10 m, ao longo de um trecho do rio, sendo amostrados todos indivíduos com perímetro à altura do peito maior ou igual a 20 cm (DAP = 6,36 cm). Os 673 indivíduos amostrados distribuíram-se entre 120 espécies, 83 gêneros e 37 famílias. Myrtaceae foi a família de maior riqueza, com 28 espécies, seguida por Fabaceae (11), Rubiaceae e Lauraceae (8 cada uma). Euterpe edulis Mart. (Arecaceae), Chrysophyllum... |

| Fine roots, <2 mm in diameter, are responsible for water and nutrient uptake and therefore have a central role in carbon, nutrient and water cycling at the plant and ecosystem level. The root length density (RLD), fine root biomass (FRB) and vertical fine root distribution (VRD) in the soil profile have been used as good descriptors of resource-use efficiency and carbon storage in the soil. Along altitudinal gradients, decreases in temperature and radiation inputs (depending on the frequency of fog events) may reduce decomposition rates and nutrient availability what might stimulate plants to invest in fine roots, increasing acquisition of resources. We evaluated the seasonal variation of fine root parameters in a Lowland and Montane forest at the... |

| Durante o levantamento de fungos mitospóricos associados ao folhedo de Tibouchina pulchra Cogn. coletado na Reserva Biológica de Paranapiacaba (Mata Atlântica), Santo André, estado de São Paulo, vinte e dois Hyphomycetes foram isolados. As folhas passaram pela técnica da lavagem sucessiva de substratos com água destilada esterilizada e foram incubadas em câmaras-úmidas. Três espécies constituem novos registros para o Brasil, Rhinocladiella cristaspora Matsushima, Venustusynnema ciliata (Castañeda, G. Arnold & A. Guerra) Castañeda & Kendrick e Vermiculariopsiella cubensis (Castañeda) Nawawi, Kuthubutheen & Sutton; para essas são apresentadas descrições, distribuição geográfica, comentários e ilustrações. |

| We studied the flora of vegetation islands on rock outcrops on the Itatiaia Plateau (22°21'S and 44°40'W), at 2,400 m.a.s.l. A total of 114 vascular plant species, which correspond to ca. 20%-25% of the currently inventoried flora of the plateau, were sampled in 197 small vegetation islands (total area of 0.034 ha). Xerophytes and hydrophytes were often found side by side due to environmental heterogeneity at a small scale, explaining in part the high species diversity. Rock outcrops may support floras quite distinct from those in neighbouring habitats, due to the action of strong environmental filters, but in Itatiaia the geographic distribution patterns among rupicolous plants appear to mimic those described for the whole flora around it, with 15.1% of... |
