The city of Cubatão is a densely populated area with high industrial activity. In the area there are also important linear works as roads, railways, pipelines, aqueducts and lines of transmission of energy. The geological and geomorphological features of the municipality, combined with the human activities, make the site an area heavily prone to the landslides, so a region at high risk. In this work, landslide scars were extracted in aerial photos from 1985 and 1994, years that recorded a high incidence of landslides. Quantitative analysis of the relationship between the occurrence of scars and the forms of tracks were conducted, based on an intensive survey of scars in the region, represented by 2595 extracted scars, with the aim of contributing to a better understanding of the slipping processes in the Serra do Mar paulista and thus to the reduction of risks in the region. Achievements have concluded that the greatest percentage of slides in the region is linked to the strands straitght, followed by convex, which confirms previous studies conducted in the region, in a qualitative way or with a much lower number of scars.

The objective of this study was to conduct an inventory of food plants cultivated and collected from the native and ruderal vegetation in the Atlantic Forest region by the rural population residing in the Santa Virginia Nucleus of the Serra do Mar State Park (Puruba and Guaricanga neighborhoods) and surroundings (Vargem Grande neighborhood). The 23 interviewees were sampled to meet the following criteria: originating from the rural area of the municipalities where the Nucleus is located; more than 45 years old; close familiarity with working the land. A total of 146 botanical species were identified, distributed among 43 botanical families, with the families Solanaceae and Cucurbitaceae being the most represented and basically horticultural. The Shannon-Wiener diversity index and Pielou evenness were 1.90 (base 10) and 0.95, respectively, for the group residing in the Nucleus and 1.97 and 0.92 for the population located in the area surrounding the Nucleus. The two groups of neighborhoods presented similarity regarding the food plants cited (75%), and about 17% of the plants cited are native to the Atlantic Forest. We found significant richness and variety of species cultivated in the yards and fields which serve to complement the diet, which is composed mainly of items purchased at local businesses. The rural communities studied revealed themselves to be an important germplasm conservation system for cultivated plants, with 96 ethnovarieties identified for 12 botanical species, most of which are kept in the communities.

Por ocupar área de transição entre três compartimentos distintos do relevo (Planalto Atlântico, Serra do Mar e Planície Costeira) e encontrar-se geograficamente influenciada pela complexa relação entre Oceano e Continente (litoral paulista), a alta bacia do rio Itanhaém agrega uma complexidade que demanda estudos científicos. Neste contexto, o objetivo deste artigo é demonstrar a influência que as características morfométricas da alta bacia do rio Itanhaém possuem sobre a sua morfodinâmica. Para tanto, foram analisadas a carta geomorfológica e a carta de energia do relevo. A carta de energia do relevo tem o objetivo de quantificar o potencial que o relevo possui para o desencadeamento de processos morfogenéticos. A carta geomorfológica propiciou a espacialização das formas do relevo, possibilitando a dedução dos processos que ocorrem sobre este, sejam naturais ou induzidos pela atuação antrópica. Como resultado, observou-se a correlação espacial entre as feições desnudacionais e as classes mais altas de energia do relevo. Assim, os parâmetros morfométricos utilizados para a elaboração da carta de energia do relevo que identificaram setores potencialmente suscetíveis aos processos morfogenéticos são justificados pelas feições denudacionais espacializadas.

Nas florestas Neotropicais, os mamíferos podem desempenhar papéis importantes como predadores e/ou dispersores de sementes, polinizadores, frugívoros, folívoros ou até mesmo predadores de topo e, por isso, são importantes para a manutenção e regeneração das comunidades biológicas. Os objetivos deste trabalho foram: (i) realizar um levantamento da diversidade de espécies de aves e mamíferos cinegéticos no PETAR, (ii) estimar a abundância relativa, densidade, biomassa e tamanho populacional das aves e mamíferos mais avistados, (iii) comparar a diversidade e abundância das espécies estudadas em dois núcleos com diferentes pressões antrópicas. A área de estudo esta localizada na Serra da Paranapiacaba, que é a segunda maior área protegida do estado de São Paulo, possuindo mais de 125 000 ha, onde quatro Unidades de Conservação estão conectadas (Parque Estadual Turístico do Alto Ribeira, Parque Estadual de Intervales, Parque Estadual de Carlos Botelho e Estação Ecológica Xituê). Ligadas a Serra do Mar, estas UC´s formam um grande corredor de biodiversidade que compreende o maior contínuo florestal de Mata Atlântica. O presente estudo segue o mesmo protocolo de amostragem do projeto BIOTA Fapesp (01/14463-05). As espécies alvo da amostragem foram aves de grande porte (Cracídeos, Tinamídeos e Fasianídeos) e mamíferos acima de 1kg, com exceção do esquilo (Guerlinguetus ingrami) que é uma espécie indicadoras de áreas defaunadas. Para o levantamento qualitativo (riqueza) foram utilizadas identificação de pegadas, carcaças, rastros e observações ad libitum. Já o levantamento quantitativo (abundância, densidade, biomassa e tamanho populacional) foi obtido pelo método de transecções lineares, em que para cada indivíduo observado foram obtidas a distância perpendicular animal-trilha, horário do avistamento, número de indivíduos e sua localização...

Landscape is the result of interaction between tectonic, weathering and pedogenetic processes, so it is necessary to understand the morphogenesis and relate it to the landforms and landscape. Therefore, this project comprises a geomorphological characterization of some areas associated with the fault zones of Taubaté Basin, at the surroundings of the cities from São José dos Campos to Taubaté SP, emphasizing the Quaternary landscape evolution, where the normal faults played an important role in controling and they were originated, mostly, from the reactivation of Precambrian fault zones by tectonic action. The rift valley scenario is highlighted in the region, identifying the sharp relief from the basin boundary, featuring both Serra do Mar and Serra da Mantiqueira, and a central depressed area where the Taubaté Basin is located. Deforming or modifying basin features are identified, promoting the rearrangement and conditioning of the drainage network and relief, which indicates the presence of morphostructures, conducting to the deduction of a late tectonic process

Boracéia Biological Station, near the city of Salesópolis, SP, is located in one of the most well-defined centers of endemism in eastern Brazil - the Serra do Mar Center. While the station was established only in 1954 under the auspices of the Museu de Zoologia da Universidade de São Paulo, the avifauna of this locality had already attracted the attention of ornithologists by the 1940s, when the first specimens were collected. Here we describe the ornithological history of the Boracéia Biological Station with a review of all the bird species recorded during more than 68 years, including recent transect and mist-netting records. Boracéia's records were found in museums, literature and unpublished reports that totaled 323 bird species when recent data is also considered. Of these, 117 are endemic to the Atlantic forest and 28 are threatened in the state. Although there are a few doubtful records that need to be checked, some species are the only sightings in the state. Boracéia includes a recently discovered species near the station site and is extremely important for the conservation of Atlantic forest birds.

The current study investigated the occurrence of ticks and their rickettsiae in the Serra do Mar State Park, which encompasses one of the largest Atlantic rain forest reserves of Brazil. From July 2008 to June 2009, a total of 2,439 ticks (2,196 free living and 243 collected on hosts) was collected, encompassing the following 13 species: Amblyomma aureolatum (Pallas), Amblyomma brasiliense Aragao, Amblyomma dubitatum Neumann, Amblyomma fuscum Neumann, Amblyomma incisum Neumann, Amblyomma longirostre (Koch), Amblyomma naponense (Packard), Amblyomma nodosum Neumann, Amblyomma ovale Koch, Haemaphysalis juxtakochi Cooley, Ixodes aragaoi Fonseca, Lodes loricatus Neumann, and Rhipicephalus sanguineus (Latreille). Ticks were submitted to polymerase chain reaction assays targeting portions of the rickettsial genes gltA and ompA. Polymerase chain reaction products were DNA sequenced and compared with corresponding sequences available in GenBank. Rickettsia bellii, a rickettsia of unknown pathogenicity, was detected in one A. aureolatum, one A. ovate, and three A. incisum specimens. At least 8.8% (3/34) of the free-living A. ovale ticks, 13.6% (8/59) of the A. ovale ticks collected from dogs, and 1.9% (1/54) of the R. sanguineus (Latreille) ticks were found to be infected by Rickettsia sp strain Atlantic rain forest, a novel strain that has been shown to cause an eschar-associated spotted fever in the state of Sao Paulo. Our results suggest that A. ovale is the vector of Rickettsia sp strain Atlantic rain forest in the state of Sao Paulo.
