Considering that tourism tends to reproduce itself privatizing the areas where it installs, the secondary residence has been an urban element responsible for the private appropriation of the public spaces of coastal of Nísia Floresta. The private appropriation of these accesses, for secondary residences, constitute in an issue-problem of the research. The principal goal is to analyze the relationship of the consumers/users of secondary residences with the public space; and, specifically, identify how the government has been acting and manifesting itself about the occupation of the coastal of Nísia Floresta; as also to verify how the secondary residence has been appropriating privately of the public access of the coastal. On account of the scarce literature about secondary residences and the importance of the public access to beaches for the inhabitant, the present work aims to contribute to the discussion of this theme. The secondary residences in Rio Grande do Norte began in the late nineteenth century, becoming more common in the 90s, when the coast south of Natal is appropriated from local vacationers. In 2000, foreign investment began to be applied in real state and tourism, producing closed developments, served in leisure infrastructure, trade, and hospitality, mainly to external demands. The methodology included a bibliographic survey, data collection and in lócus observation. Applied questionnaires and interviews were performed with consumers/users of the secondary residences, permanent residents and government, respectively. To the legal grounding, taken as a reference the article. 10, of the law 7.661/88 to establish that the beaches are goods of common use . Considering the conclusive analysis of the research, can be said that the right of free access and use of the beach is committed for the benefit of the consumers/users of secondary residences, due to the negligence and omission of the government

O presente estudo teve como objetivo a elaboração de uma chave de identificação ilustrada para diferenciar as espécies de camarões marinhos Dendrobranchiata, com ocorrência no litoral do Estado de São Paulo até a profundidade de 40m. As 13 espécies apresentadas neste trabalho foram obtidas mediante coletas mensais durante os anos de 1995 a 2000 na região de Ubatuba, SP . Nesta chave estão incluídas as espécies de interesse econômico, como os peneídeos Xiphopenaeus kroyeri, Farfantepenaeus brasiliensis, F. paulensis, Litopenaeus schmitti, Artemesia longinaris e o solenocerídeo Pleoticus muelleri. Além destas espécies, também foram adicionados os camarões que não são alvos das frotas pesqueiras, entre eles, Rimapenaeus constrictus, Acetes americanus, Peisos petrunkevitchi e os sicionídeos Sicyonia dorsalis, S. typica, S. laevigata e S. parri. A chave proposta servirá como uma ferramenta no auxílio da identificação dos camarões Dendrobranchiata, quer seja por pesquisadores ligados à área científica, como também por pessoas relacionadas aos órgãos responsáveis pelo controle da pesca, principalmente, na época do defeso.

Uma climatologia de frentes frias é estabelecida para o litoral do Estado de Santa Catarina, com base nos dados de reanálises do NCEP-NCAR, do período de 10 anos, de 1990 a 1999. As passagens de frentes frias foram objetivamente identificadas levando em conta o giro do vento para direção sul, persistência do vento de sul por pelo menos um dia, e uma queda de temperatura do ar simultânea ao giro do vento ou até dois dias depois. Os resultados mostram que, na média, de 3 a 4 frentes frias atingem a costa de Santa Catarina, mensalmente, com um intervalo de 8 dias. As análises da composição de dados, usando como referência os dias de passagens de frentes frias em Santa Catarina, mostram claramente um padrão climatológico de evolução com frente fria movendo-se tipicamente de sudoeste para nordeste. em termos das médias sazonais, durante o inverno, um dia antes da passagem em Santa Catarina (dia -1), a frente fria é observada no Rio Grande do Sul, e depois de passar por Santa Catarina (dia 0), continua avançando para latitudes mais baixas, alcançando o litoral do Rio de Janeiro um dia depois (dia +1), até atingir posteriormente latitude de aproximadamente 20ºS (dia +2), já em fase de dissipação. No terceiro dia após a passagem por Santa Catarina, ela não é mais identificada. Padrão climatológico de evolução semelhante é observado no verão, embora nessa época as frentes frias tenham menor intensidade e dissipação ligeiramente mais rápida.

A região do litoral norte do Estado de São Paulo registrou 14, 30 e 104 casos de leishmaniose tegumentar americana nos anos de 1993, 1994 e 1995 respectivamente. Com objetivo de caracterizar a fauna e a distribuição sazonal e horária das espécies de flebotomíneos foram realizadas coletas quinzenais de formas adultas durante o período de dezembro de 1995 a novembro de 1996, utilizando-se armadilhas luminosas do tipo CDC, no interior da residência, no peridomicílio e na mata durante 12 horas a partir do crepúsculo vespertino. No peridomicílio foi utilizada, durante 6 horas também a partir do crepúsculo vespertino, armadilha de Shannon instalada a 100 metros da casa. A cada 3 meses esta armadilha foi utilizada durante 12 horas. Foram observadas flutuações das densidades populacionais, bem como as ocorrências intra e extradomiciliar das espécies predominantes. Lutzomyia intermedia foi a espécie mais abundante nas diferentes armadilhas utilizadas e nos ambientes investigados.

The coast environments were the first areas the man occupied in Brazil and they present, nowadays, high urbanization indexes. So, it's very important to analyze the environmental quality of those areas. The geomorphologic aspects are valuable for that analysis because they constitute the physical substrate on which such ant anthropic activities are developed. The cartography of geomorphologic features is essential to supply subsidies for the handling of coastal areas. However, the question about what proceedings are adequate to the geomorphologic cartography of recent sedimentation coastal lands is still in discussion by many authors. This article aims to compare two different technical proposals for mapping São Paulo's south coast, a sector that shows a great depositional complexity. The features related to recent sedimentation sectors were mapped because it's considered that they are necessary to understand the morphodynamic and, at the same time, they demonstrate difficulties in geomorphologic cartography standardization. Through the analysis of the produced maps it's possible to notice that the two proposals have positive aspects, but both need adaptations to cartographically demonstrate the geomorphologic complexity of São Paulo's south coast.

This paper presents a method applied to the seacoast town of Peruibe, São Paulo State, Brazil. The method encompasses the application of remote sensing interpretation techniques and field survey to obtain geotechnical data and thus generate cartographic products composed of easily grouped units that work as database objects and can de used to assist geotechnical zoning. The so-called Compartmentalization Basic Units (CBUs) show the smallest land surface analyzed from its physiographic elements and have in their cores the same geotechnical properties, making it easier to analyze the potentialities and the fragilities of the physical environment and its susceptibility to the action of natural and anthropic processes. In the study area, sixty-eight units were individualized in which geotechnical properties were inferred by photo interpretation criteria, using textural properties of the image adjusted with field observations. The method proved to be easily reproducible, and is especially useful in regions where the absence of basic maps makes it impossible to establish homogeneous zones through traditional overlay of different topic informations.

Deformities and abnormalities in crustaceans have been associated to genetic problem, which occurred during molt process, damage caused by ectobionts, predators or environmental stress caused by chemical wastes. Some crab specimens collected in the São Paulo littoral were found having body abnormalities. They belong to the following crab species: Callinectes ornatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) and Leurocyclus tuberculosus (H. Milne Edwards; Lucas, 1843). Samplings were performed by trawling during July 2008, August and October 2009 at the Ubatuba region, São Paulo State, Brazil. Body abnormalities were verified in the cheliped dactyl (C. ornatus an adult male), carapace deformities (A. cribrarius an adult male) and abdominal alterations (C. ornatus an adult female; L. tuberculosus an adult male and an ovigerous female). The record and analysis of such occurrences can help in the distinction of natural or human impact caused alterations. In this way, the occurrence study of this kind of body alterations could provide tools in order to control unprotected environmental areas, as well as bring subsides to understand the unusual variations during the ontogeny of important species in the benthic community.

Stranding of oceanic-pelagic elasmo branchs in the southeastern Brazil are reported. Data comes from animals observed in the coast of São Paulo state, between 1999 and 2012. Nine individuals of two species were recorded: Pteroplatytrygon violacea (n = 5; mostly during the winter) and Isurus oxyrinchus (n = 4; two in the winter and two in the summer). For P. violacea the strandings restricted to the austral winter suggest that the species follows the intrusion of high temperatures water masses recorded in southeastern Brazil during this season, bringing some individuals to shallow waters. For I. oxyrinchus is possible that individuals escaped from hooks of the commercial pelagic long line fishery and suffered injuries in the esophagus and in the gastric wall, stranding due to difficulties in locomotion and feeding. As these stranded sharks were not necropsied and only two animals were observed during the austral summer, we cannot exclude other causes of beaching such diseases or the intrusion of cold water masses in the continental shelf during this season.
