In the present study, we report tick infestations on wild birds in plots of the Atlantic Forest reforested fragments with native species and plots reforested with Eucalyptus tereticornis in the municipality of Rio Claro, State of Sao Paulo, Brazil. A total of 256 birds were captured: 137 individuals of 33 species, in planted native forest; and 128 individuals of 37 species, in planted Eucalyptus tereticornis forest. Nymphs of two tick species were found on the birds: Amblyomma calcaratumand Amblyomma longirostre, the former was more abundant in the fragments reforested with Atlantic forest native species, and the latter in the fragment reforested with E. tereticornis. New host records were presented for A. calcaratum.

The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in the country. However, despite the large number of studies in this area, there are still many sampling gaps within biomes such as the Atlantic Forest that are considered global conservation priorities due to the high rate of endemism and human disturbance. As a result of political and historical pressure, this biome has been reduced to less than 12% of its original extent and, despite its importance for global biodiversity conservation, only a small percentage of its original vegetation cover (1%) has some form of legal protection. This is the case of the Parque Estadual Turístico do Alto Ribeira (PETAR) which, together with the Parque Estadual de Intervales, Parque Estadual Carlos Botelho and Mosaico de Unidades de Conservação de Jacupiranga, forms of an ombrophilous forest continuum of 360 thousand ha in the south of São Paulo State. This study presents a list of amphibians and reptiles from the PETAR, with information on the local distribution and habitat use of the species. The survey was conducted from October to December 2009, completing a total of 15 sampling days using four complementary methods of active sampling: visual encounters, auditory encounters, searches by car and incidental encounters. We recorded a total of 91 species belonging to 53 genera and 24 families. This high diversity can be attributed to the existence of a wide variety of habitats and microhabitats in this region, such as the various aquatic sites used by many species of anuran amphibians. Moreover, the PETAR features a large altitudinal gradient (80 - 1,160 m elevation) that gives a large climatic, geological and hydrological heterogeneity to the area. This inventory is an important contribution to the expansion of knowledge about these assemblages in the Atlantic Forest to the south of Serra de Paranapiacaba mountain range, and provides support for the conservation of these groups in São Paulo State.

We analyzed richness, composition and mass of snakes in two sites in the Atlantic forest of Ilha do Cardoso (25º 03' S and 47º 53' W), an island (22,500 ha), Cananéia municipality, São Paulo State, Brazil. A monthly index of arthropod availability (in mm³) was estimated in each site through capture rates in pit-fall traps. Fallen fruits were collected along trails in the study sites (mass of fruit gave an index of fruit availability) and small mammals were sampled in grids with 120 traps which covered the lowland (5.2 ha) and in the slope forests (3.6ha). The abundance and mass of small mammals were standardized for the size of each sampled area (in g.ha-1). To sample snakes we established 20 pit-fall traps in each area and performed monthly transects in four consecutive days (totaling 1000 m long) along trails in the study sites. Snakes found were measured, weighted marked and released. Abundance and total mass of snakes were standardized by the size of each area. The areas differed consistently in in the productivity of arthropods, fruits and small mammals, and also in richness, composition and total mass of snakes. We found 36 individuals (total mass = 9884 g) of 12 snake species belonging to three Families (Colubridae, Elapidae and Viperidae) in the lowland forest, whereas in the slope forest we sampled only 9 individuals of 2 species (total mass = 1820 g). Our results suggest that the area of lowland forest, showing higher productivity of arthropods, fruits and small mammals, maintains a snake community with a higher richness, diversity and biomass than its slope forest counterpart.

Miconia goldenbergiana, a new species from the Atlantic Forest in southeastern Brazil, is described and illustrated. The new species have been extensively collected since the end of the XIX century but have been confused with M. budlejoides and M. formosa, species that also have discolorous and suprabasal leaves and glomerulate inflorescences. From the first species, it can be distinguished by papyraceous leaves with the abaxial surface covered by lepidote trichomes. From the second species, it can be distinguished also by the texture of leaves, and by its narrower size, crenulate to serrulate margins and acute base, besides the smaller size of the flowers. The new species is known from the states of Espírito Santo, Rio de Janeiro and eastern São Paulo, and is in danger of extinction.

Abstract. Stream-water flows and in-stream nitrate and ammonium concentrations in a small (36.7 ha) Atlantic Forest catchment were simulated using the Integrated Nitrogen in CAtchments (INCA) model version 1.9.4. The catchment, at Cunha, is in the Serra do Mar State Park, SE Brazil and is nearly pristine because the nearest major conurbations, São Paulo and Rio, are some 450 km distant. However, intensive farming may increase nitrogen (N) deposition and there are growing pressures for urbanisation. The mean-monthly discharges and NO3-N concentration dynamics were simulated adequately for the calibration and validation periods with (simulated) loss rates of 6.55 kg.ha−1 yr−1 for NO3-N and 3.85 kg.ha−1 yr−1 for NH4-N. To investigate the effects of elevated levels of N deposition in the future, various scenarios for atmospheric deposition were simulated; the highest value corresponded to that in a highly polluted area of Atlantic Forest in Sao Paulo City. It was found that doubling the atmospheric deposition generated a 25% increase in the N leaching rate, while at levels approaching the highly polluted São Paulo deposition rate, five times higher than the current rate, leaching increased by 240%, which would create highly eutrophic conditions, detrimental to downstream water quality. The results indicate that the INCA model can be useful for estimating N concentration and fluxes for different atmospheric deposition rates and hydrological conditions.

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 contaminations. With our results, the number of Streblidae species increased from 31 to 36 in São Paulo State.
