Evaluation of the geotourism potential of the northern region of São Sebastião island (São Paulo, Brazil)

A motivação do presente estudo é o emprego da geoconservação no manejo de atrativos turísticos em unidades de conservação de proteção integral, com vistas ao geoturismo, tendo como área de estudo a região norte da Ilha de São Sebastião, no município de Ilhabela, SP. Foram inventariados 14 sítios de geodiversidade, e avaliados quantitativamente quanto aos potenciais usos turísticos convencional e de aventura, e valor científico. Para seleção dos sítios mais aptos ao geoturismo foram considerados aqueles que apresentaram simultaneamente alto potencial turístico, cuja relevância é condicionada por aspectos como logística, acessibilidade, apelo cênico e unicidade, e alto valor científico, cujas informa- ções constituem a matéria-prima das atividades interpretativas, adaptadas a uma linguagem acessível ao público leigo. Dentre os resultados obtidos, destacam-se os seguintes sítios de geodiversidade prioritários ao geoturismo: Sienitos da Praia da Garapocaia (SG9), Geodiversidade no Pico do Baepi (SG 6) e Caminhos geológicos das costas norte (SG11) e leste (SG 12).The present study aims to apply the geoconservation to tourist management in full-protection conservation units, focusing on geotourism. For this purposes, the study area is the northern region of São Sebastião Island, on the north coast of State of São Paulo, Brazil. Fourteen geodiversity sites were inventoried, which were quantitatively evaluated for the potential of conventional and adventure tourism and scientific value. The sites classified as most suitable for geotour ism projects are those that simultaneously presented high tourist potential, whose relevance is conditioned by aspects such as logistics, accessibility, scenic appeal and uniqueness, and scientific value, whose information constitutes the raw material of the interpretive activities, adapted to a language accessible to the lay public. Among the results obtained, the following geodiversity sites are highlighted as priority to geotourism: Syenites from Garapocaia Beach (SG9), Geodiversity in Baepi Peak (SG6) and North and East Coast Geological Paths (SG11 and SG12).CAPES -Coordenação de Aperfeiçoamento de Pessoal de Nível Superior(undefined

Causes, consequences and biomarkers of stress in swine: an update

BACKGROUND: In recent decades there has been a growing concern about animal stress on intensive pig farms due to the undesirable consequences that stress produces in the normal physiology of pigs and its effects on their welfare and general productive performance. This review analyses the most important types of stress (social, environmental, metabolic, immunological and due to human handling), and their biological consequences for pigs. The physio-pathological changes associated with stress are described, as well as the negative effects of stress on pig production. In addition an update of the different biomarkers used for the evaluation of stress is provided. These biomarkers can be classified into four groups according to the physiological system or axis evaluated: sympathetic nervous system, hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-gonadal axis and immune system. CONCLUSIONS: Stress it is a process with multifactorial causes and produces an organic response that generates negative effects on animal health and production. Ideally, a panel of various biomarkers should be used to assess and evaluate the stress resulting from diverse causes and the different physiological systems involved in the stress response. We hope that this review will increase the understanding of the stress process, contribute to a better control and reduction of potential stressful stimuli in pigs and, finally, encourage future studies and developments to better monitor, detect and manage stress on pig farms

Landslides Zonation Hazard: relation between geological structures and landslides occurrence in hilly tropical regions of Brazil

<div><p>ABSTRACT This paper presents a new approach of landslides zonation hazard studies, based on an integrated study of structural data along with geomorphological and external factors, in a hilly regions of Brazil, covered by a tropical humid rain-forest, called Serra do Mar. The Serra do Mar consists of a hilly region along the east coast of Brazil, with high slopes and many geological structures in a gneiss - migmatitic terrain. In contrast to traditional approaches, this method proposes that structural data (foliation, fractures and bedding planes) and its relation with the slope geometry, is important to be consider in the landslide zonation hazard, along with declivity, relative relief, soil and rock properties, land use and vegetation cover and hydrogeological and climate factors. Results show that slopes with high hazard have the same dip direction of geological structures. Landslide zonation hazard using structural data contributes to a better understanding of how these structures, preserved in tropical residual soils, influence on slope stability and generates landslides.</p></div
