| Abstract Piauí, a Brazilian Northeast state, has been considered one of the most important regions for the presence of new taxa in ants globally, especially considering the ecosystems’ diversity formed by the transition of the three biomes in the state, the Cerrado, Caatinga and the Atlantic Forest. Despite the recent increase in studies of ant diversity in the Neotropical region, Piauí still represents a major knowledge gap regarding its ant fauna. Therefore, this study aimed to increase the knowledge about the ant fauna of the state by generating a list of species with data obtained from the literature, online repositories and collection expeditions to the Serra da Capivara and Serra das Confusões National Parks. A total of 152 species in 52 genera and... |

| Over 70% of threatened birds in the state of Rio Grande do Sul, south Brazil, inhabit forest environments. The creation and maintenance of protected areas is one of the most important measures aiming to mitigate these problems. However, the knowledge of the local biodiversity is essential so that these areas can effectively preserve the natural resources. Between 2004 and 2009 we sampled the avifauna in two conservation units in Rio Grande do Sul: Floresta Nacional de Canela (FNC) and Parque Natural Municipal da Ronda (PMR), both representative of the Mixed Humid Forest (Araucaria Forest). A total of 224 species was recorded, 116 at FNC and 201 at PMR, ten of which threatened regionally: Pseudastur polionotus, Odontophorus capueira, Patagioenas... |

| ABSTRACT Streblidae is the family of bloodsucking flies, mostly tropical and subtropical, that are obligate ectoparasites of bats. A high number of these fly species are found in the Atlantic Forest, but there is little information about their quantitative descriptors. In this paper, we describe the prevalence, mean intensity, and infracommunities of streblid bat flies on phyllostomid bats from the Parque Estadual da Ilha do Cardoso, São Paulo state, Brazil. Surveys were conducted from July 1990 to July 1991 in distinct places of the island, with a total of 454 flies of 30 species collected from 132 bats of 15 species. From those, we found 44 host-parasite associations and 31 infracommunities that suffered variations due to accidental associations or... |

| The aim of this study was to evaluate abundance, biomass and diversity of earthworms in the southern coast region of the Mata Atlântica biodiversity hotspot. A total of 51 study sites in pastures, banana monocultures, mixed agroforestry systems, secondary forests in succession and old-growth forests near the coast of Paraná, Brazil, were evaluated. Each site was sampled once. Species richness of the earthworms was generally low and varied little between sites. At all sites except for one, the peregrine species Pontoscolex corethrurus (Glossoscolecidae) strongly dominated. Three other peregrine species, Amynthas corticis, Amynthas gracilis (Megascolecidae) and Ocnerodrilus occidentalis (Ocnerodrilidae), were frequent in moist sites. No autochthonous species... |

| Several aspects of nutrient cycling were studied at two sites of Atlantic Forest, in São Paulo State, Southeast Brazil (23o46 S; 46o18 W), which exhibited different degrees of forest structure decline caused by the air pollution emitted by the industrial complex of Cubatão, being referred here as the most and least affected sites (MAS and LAS, respectively). These investigations were developed during 1984 - 1986, a period in which the most severe negative effects of air pollution could be observed. Concentrations and amounts of N, P, K, Ca, Mg and S in four ecosystem compartments (leaves, litter layer, soil and roots) and in rainfall, throughfall and litterfall are briefly presented. At each site, the content of mineral elements generally decreased from... |

| ABSTRACT This study aimed to determine and spatialize the soil quality index (SQI), in relation to chemical and physical attributes, and evaluate its use in the payment for environmental services in the Sub-Basin of Posses, Extrema-MG, Brazil, which represents the Atlantic Forest Biome. SQI values were influenced by both the replacement of native forests by stands of eucalyptus and by pastures and annual crops, reflecting in the reduction of soil quality in the sampled layer in the evaluated systems. The spatialization of SQI showed values ranging from 0.40 to 0.80, with some specific areas with high values and others with values above 1.00 (native forest). The reforestation with eucalyptus conditioned most of the soils with low chemical and physical... |

| The development time of the immature forms of Sabethes aurescens Lutz, 1905, from perforated bamboo in the southern Brazil rain forest was studied under laboratory conditions. Mean development periods were 5±2.23, 10±5.20, 14±8.26, 36±13.90 and 9±2.43 days, respectively, for the four larval instars and pupae. The 4th instar of females was longer than that of males. Implications of the long development time of the immature forms of Sa. aurescens are discussed. |

| ABSTRACT Ants can use twigs from fragments of tree branches as a nesting resource. The present study analyzed gatherings of ants in twigs of Albizia niopoides, a Fabaceae native to the Atlantic Forest that is used in landscaping in parks and squares in Brazil. Expeditions were performed in an urban park located in Atlantic Forest areas between February and June 2014. A total of 70 twigs with ants were collected and included 9357 workers, 2309 broods ants, 68 winged ants and 19 queens. Four subfamilies, 10 genera and 17 species/morphospecies were recorded. The species with the largest number of nests were Nylanderia sp.1, Hypoponera sp.4, and Wasmannia auropunctata. Ants of different species were found coexisting in the same twig, and Pheidole gr. tristis... |
