Abstract. Two areas in the Atlantic Forest (São Paulo State, Brazil), with contrasting environments in respect of human occupation, were monitored from 1999 to 2001. One area named PEFI (23°38'08''-23°40'18'' S and 46°36'48''-46°38'00'' W) at an altitude of 798 m a.s.l., 526.4 ha in area and about 50 km from the sea, lies in a State Park within the largest metropolis of South America - São Paulo. The other area, named CUNHA (between 23°13'18'' and 23°16'10'' S and 45°02'53'' and 45°05'15'' W) about 1050 m a.s.l. with an area of 2854 ha and about 15 km from the sea, is also within a State Park in the Atlantic Forest, but is surrounded by rural areas and small villages. For each area, the rainfall and throughfall chemistry were examined and pH and Na+, K+, Mg2+, Ca2+, NH4+, Cl-, NO3- and SO42- as well as trace metals were determined. Compared with PEFI, CUNHA is characterised by low chemical fluxes and the largest differences are for the ions such as Ca2+, H+, NO3- and SO42- which are mainly anthropogenic in origin. Differences in throughfall chemical fluxes are linked to the nutritional status of the trees.

Simplified Mathematical Model

In São Paulo State, mainly in rural areas, the utilization of wooden poles is observed for different purposes. In this context, wood in contact with the ground presents faster deterioration, which is generally associated to environmental factors and, especially to the presence of fungi and insects. With the use of mathematical models, the useful life of wooden structures can be predicted by obtaining "climatic indexes" to indicate, comparatively among the areas studied, which have more or less tendency to fungi and insects attacks. In this work, by using climatological data of several cities at São Paulo State, a simplified mathematical model was obtained to measure the aggressiveness of the wood in contact with the soil.

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.

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.

During a floristic study, carried out in the Parque Estadual Turístico do Alto Ribeira (PETAR), in São Paulo state, Southeastern Brazil, Peperomia bernhardiana, a poorly known species of Atlantic Forest, has been collected. We present an emended description of the species based on the recently collected specimens and provide color photographs of fresh specimens. We verified the need to designate a neotype for this name and propose one to substitute the destroyed holotype.

Abstract Although São Paulo state has one of the best known amphibian fauna in Brazil, there are still protected areas for which the species composition remains unknown. Here, we present the first species list of anuran amphibians in Vassununga State Park. This area is one of the last remnants of semideciduous Atlantic Forest and Cerrado in the northeastern region of São Paulo state, southeastern Brazil. To survey species, we visited six sites (two ponds, two streams, and two transects) in December, January, and February of 2014-2015 and 2015-2016, totalizing 18 days of field samplings at each site. We recorded 24 anuran species belonging to four families: Bufonidae (2 species), Hylidae (11 species), Leptodactylidae (10 species), and Microhylidae (1 species). Anurans consist mainly of generalist and widely distributed species. Although none of the species recorded are threatened with extinction according to the International Red List of Endangered Species (IUCN), four species have declining population and another three species have unknown population trends.

ABSTRACT During a fungi survey in the brazilian Atlantic Forest in São Paulo, São Paulo State, Brazil, polypores growing on decaying wood were collected and fragments of the basidiomata were used to obtain isolates in pure culture. A total of 37 isolates were obtained and 23 species were identified. Cultural features of Bjerkandera atroalba, Henningsia brasiliensis, Rigidoporus undatus, and Steccherinum reniforme were described for the first time. A total of 31 isolates were evaluated in terms of their ability to oxidize the Remazol brilliant blue R dye (RBBR) and guaiacol. The results of these tests indicate that all isolated species were associated with white rot in the wood. Laccase and peroxidase activities were detected by drop tests using solutions of α-naphthol and pyrogallol. Production of cellulases and siderophores was detected with carboxymethylcellulose (CMC) and chrome azurol S (CAS) agar, respectively.

This paper reports on the genera Cystoderma, Cystodermella and Ripartitella from Atlantic Rainforest, Southeast Brazil. They are represented by Cystoderma chocoanum, Cystodermella contusifolia, C. sipariana and Ripartitella brasiliensis. Cystoderma chocoanum is reported for the first time outside the type locality (Colombia) and its relationship with others species of Cystoderma, based on nLSU rDNA sequences, is discussed.
