| El mantillo del suelo (horizontes Oi y Oe) de ecosistemas boscosos es utilizado como hábitat, fuente de nutrientes y energía para una gran diversidad de organismos. Ocurre, en consecuencia, un flujo de carbono (C) desde el detritus debido a la producción de CO2 por respiración de la biota. En este trabajo se midió y comparó la actividad respiratoria en condiciones de laboratorio de muestras de mantillo, colectadas en tres tipos de bosques del centro y sur de Chile: bosque Nordpatagónico (Nothofagus), bosque Siempreverde de Coníferas (Fitzroya) y bosque Esclerófilo (Cryptocarya). Las muestras de este último se separaron en tres fracciones de tamaño de partículas (>2,4; 2,4-1,2 y < 1,2 mm), con el fin de poner a prueba la hipótesis de la constancia de... |

| This paper is a part of the studies on the Coleoptera fauna from Vila Velha, Ponta Grossa, Parana gathered through malaise and pitfall traps in sites with different floristic conditions. The present study deal with the data of pitfall trap captures, installed close to the malaise traps. The data were obtained weekly (52 samples), from September 1999 to August 2000. This survey was carried out on five areas, three of them with different plant succession stages (initial, intermediate, and advanced). The other two sites were: in Araucaria angustifolia plantation area, with the understory invaded by native forest vegetation and in the edge area. In the last one, two pitfall traps were installed, one inside the forest and other in the field vegetation. The... |

| We studied the feeding ecology of a population of Coleodactylus natalensis Freire, 1999, an endemic gecko of Atlantic Forest fragments in the state of Rio Grande do Norte, northeastern Brazil. Lizards (N = 49) were collected manually through active search in the four habitats of Parque Estadual Dunas de Natal, type locality of the species. In the laboratory, we measured the lizards and registered the number of consumed prey items identified to Order, its dimensions and frequencies. We also collected samples of leaf litter in each habitat to determine prey availability. Females were significantly larger than males, but head size did not differ between the sexes. The most important prey categories in the diet of C. natalensis based on number, volume and... |

| Herein we describe five new species of the Ectobiidae subfamilies Pseudophyllodromiinae (Amazonina spiculata sp. nov., Amazonina spinostylata sp. nov., Cariblatta duckeniana sp. nov., Cariblatta manauensis sp. nov.) and Nyctiborinae (Nyctibora nigra sp. nov.), collected in the Reserva Ducke, Manaus, state of Amazonas. The specimens were collected from litter, fallen logs, branches, and foliage. We illustrate the male genitalia of the new species. |

| Leaves of Ficus microcarpa L. f., Quercus robur L., and Alchornea triplinervia (Spreng.) Muell. Arg., submerged in a stream of the Atlantic rainforest in the "Reserva Biológica do Alto da Serra de Paranapiacaba", State of São Paulo, Brazil, were collected monthly, from April to November 1990, in order to determine the number of fungal occurrences (zoosporic fungi and aquatic Hyphomycetes), and the content of total N (%), total P (%), K+ (%), Ca+2 (%), Mg+2 (%), S+3 (%), Fe+3 (ppm), Cu+3 (ppm), Mn+2 (ppm), Zn+2 (ppm), Bo (ppm), Na+2 (ppm) and Al+3 (ppm). According to the tests of Kruskal-Wallis, Mann-Whitney and Wilcoxon, the means of the mineral content of the three types of leaves were significantly different, except for Mg+2 (%), Mn+2 (ppm), Zn+2 (ppm)... |

| A new species of Masteria L. Koch, 1873 from Manaus, Brazil, Masteria manauara sp. nov., is herein described. The specimens were collected by hand or using litter bags in the leaf litter around Attalea attaleoides (Barb. Rodr.) palm trees. The new species resembles Masteria colombiensis Raven, 1981 by lacking paraembolic apophysis on male copulatory organs and having spiniform apophysis on the ventral metatarsus I. It differs in the tibial spur, made of two subdistal, spiniform and converging spurs. Females are unique in having two spermathecae with slender helicoidal stalks. Males and females have only six eyes, and are tiny, even when compared with other Masteria species. |
