Abstract. Various methods are currently used in order to predict shallow landslides within the catchment scale. Among them, physically based models present advantages associated with the physical description of processes by means of mathematical equations. The main objective of this research is the prediction of shallow landslides using TRIGRS model, in a pilot catchment located at Serra do Mar mountain range, São Paulo State, southeastern Brazil. Susceptibility scenarios have been simulated taking into account different mechanical and hydrological values. These scenarios were analysed based on a landslide scars map from the January 1985 event, upon which two indexes were applied: Scars Concentration (SC – ratio between the number of cells with scars, in each class, and the total number of cells with scars within the catchment) and Landslide Potential (LP – ratio between the number of cells with scars, in each class, and the total number of cells in that same class). The results showed a significant agreement between the simulated scenarios and the scar's map. In unstable areas (SF≤1), the SC values exceeded 50% in all scenarios. Based on the results, the use of this model should be considered an important tool for shallow landslide prediction, especially in areas where mechanical and hydrological properties of the materials are not well known.

Physalaemus olfersii was described by M.H.K. Lichtenstein and E.K. Martens in 1856 based on two syntypes collected by I.M. Olfers between the years 1818 and 1819. Due to the brevity of it’s original description and high interpopulational variation, a taxonomic review of material assigned to the species is proposed. Morphological comparisons allowed us to associate the syntype of P. olfersii to populations distributed between the state of Espírito Santo and of São Paulo to which the southern limit is the to the municipality of São Paulo. Historical documents allowed us to define an area within Serra do Mar mountain range as the type locality of the species. Morphological and acoutics comparisons of P. olfersii from different localities in southern and southeastern Brazil revealed considerable variation among populations. Differences in call parameters and morphology, led us to conclude that three more species where under the name P. olfersii: Physalaemus lateristriga (Steindachner, 1864) comb. nov. and two new species, Physalaemus feioi sp. nov. and P. orophilus sp. nov.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.

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.

The environment most diverse in harvestmen species is the Atlantic Forest of São Paulo. However, there remains a lack of studies regarding their communities in certain regions. Among these regions is one south of the Paranapiacaba mountain range in the state of São Paulo, the Parque da Onça Parda (POP). Through nocturnal collections and pitfall traps, the region's harvestmen community has been studied. The observed richness of this site included 27 species, with dominance of three species: Holcobunus nigripalpis Roewer, 1910, Neosadocus maximus (Giltay, 1928) and Munequita sp., accounting for 68.4% of harvestmen abundance. This makes the diversity of POP more similar to the semideciduous Atlantic Forest communities of the interior than to those of the Coastal Atlantic Forest that contains the park. Its geographic location places it within the Southern São Paulo State (SSP) area of endemism, along with the Parque Turístico do Alto Ribeira (PETAR), with which it shares up to 12% similarity regarding harvestmen fauna. Richness and abundance of harvestmen were positively related to temperature and humidity. The period of animal activity (as measured by abundance and richness) varied throughout the night, being highest in the early hours during both studied seasons (summer and winter).

This study presents data on the composition and species richness of non-flying mammals in the northern part of the Parque Estadual da Serra do Mar, called Núcleo Santa Virgínia (NSV - around 17000 hectares of Atlantic Forest), São Paulo state, southeastern Brazil. The species list was based on ca. 660 km of line-transects, 25512 hours of cameras traps, 7740 trap.nights for small mammals, and 394 track-station.days, as well as occasional records and registers from local people (period 2002 to 2009). Based on these complementary methods, a total of 58 species were recorded from the 85-104 possible. Eighteen taxa are listed in the Brazilian endangered species list, 29 in the state list. The high species richness of non-volant mammals and the presence of threatened species show the importance of NSV for the conservation of Atlantic Forest mammals.

ResumoAs estradas brasileiras no Período Colonial e no Império passaram de caminhos pioneiros de penetração a vias de transporte de mercadoria e pessoal. Inicialmente, estas vias não eram pavimentadas, a não ser em trechos restritos e de curta extensão, como os acessos íngremes de serra. Neste trabalho são descritos oito destes trechos situados na Serra do Mar, construídos entre os séculos XVIII e XIX: a Calçada do Lorena, o Caminho do Ouro, a Trilha do Ouro, a Estrada Imperial, a Serra da Calçada, a Estrada do Comércio, a Calçada de Pedra e a Estrada da Taquara, todos entre São Paulo (SP) e Rio de Janeiro (RJ). O Caminho do Ouro e a Calçada de Pedra são trechos do Caminho Velho e do Caminho Novo da Estrada Real, respectivamente. A Calçada do Lorena, em Cubatão (SP) e a Calçada de Pedra, em Magé-Petrópolis (RJ) se destacam pela ligação cultural e econômica entre o litoral e o interior, tendo como origem as duas maiores metrópoles brasileiras, São Paulo e Rio de Janeiro. Os padrões de calçamento e o tratamento do material variaram de acordo com o período da obra e com a disponibilidade de recursos e capacidade técnica dos executores. Em pelo menos dois sítios preservados (Caminho do Ouro e Calçada de Pedra), observou-se que o calçamento foi feito com rochas obtidas em jazidas próximas. A disponibilidade do material pétreo utilizado foi, portanto, condicionada à diversidade geológica local. Palavras Chave: patrimônio histórico, estradas calçadas, proveniência AbstractTHE STONES OF COLONIAL AND IMPERIAL PAVED ROADS FROM SOUTHEASTERN BRAZIL. The Brazilian roads in the Colonial Period and the Empire passed, from pioneering paths of penetration, to ways of transporting merchandise and personnel. Initially, these roads were not paved, except in restricted and short stretches, such as steep mountain access. This work describes eight of these stretches located in the Serra do Mar, built between the 18th and 19th centuries: Calçada do Lorena, Caminho do Ouro, Trilha do Ouro, Estrada Imperial, Serra da Calçada, Estrada do Comércio, Calçada de Pedra and Estrada da Taquara, all between São Paulo (SP) and Rio de Janeiro (RJ). The Caminho do Ouro and the Calçada de Pedra are sections from the Old and the New Imperial Road (Estrada Real), respectively. The Calçada do Lorena, in Cubatão (SP) and the Calçada de Pedra, in Magé-Petrópolis (RJ) stand out for the cultural and economic link between the coast and the interior, having as origin the two largest Brazilian cities, São Paulo and Rio de Janeiro. The pavement patterns varied according to the period of the work and with the availability of resources and technical capacity of the executors. In at least two preserved sites (Caminho do Ouro and Calçada de Pedra), it was observed that the pavement was made with rocks obtained in nearby deposits. The availability of the stone materials was, therefore, conditioned to the local geological diversity.Keywords: historical heritage; paved roads; provenance
