Caracterização geológica tridimensional e monitoramento de dunas no litoral oriental do Rio Grande do Norte

This work presents geophysical and geological results obtained in a dunefield located in the east coast of Rio Grande do Norte State, with the aim to recognize the aeolian body depositional geometries to a future geologic modeling of the aeolian petroliferous reservoirs. The research, which was done in blowouts region situated at Nisia Floresta Municipally, included the characterization of external geometries with GPS and internal geometry analysis by GPR. Data was integrated in GoCAD software, where it was possible the three-dimensional characterization and interpretation of the studied deposits. The interpretation of GPR profiling allowed identifying: First-order bounding surfaces that separated the aeolian deposits of the Barreiras Formation rocks; Second-order bounding surfaces, which limit dune generations and Third-order bounding surfaces, a reactivation surface. This classification was based and adapted by the Brookfield (1977) and Kocurek (1996) propose. Four radarfacies was recognized: Radarfacies 1, progradational reflectors correlated to foresets of the dunes, Radarfacies 2, plain parallels reflectors related to sand sheets, Radarfacies 3, plain parallels reflectors associated to reworking of the blowout dune crest and Radarfacies 4, mounded reflectors associated to vegetated mound of sand or objects buried in subsurface. The GPR and GPS methods was also employed to the monitoring of dunefields susceptible to human activities in Buzios Beach, where the constructions along the blowout region and the tourism are changing the natural evolution of the deposits. This fact possibly to cause negative impacts to the coastal zone. Data obtained in Dunas Park, a unit environmental conservation, was compared with information of the Buzios Beach. There is a major tendency of erosion in Buzios, specifically in blowout corridor and blowout dune

Parque Estadual da Pedra da Boca (Araruna/PB): uma avaliação sobre as atividades turísticas e as ações de gestão territorial

The Conservation Units, specially the National and State parks are among the major destinations for adventure tourism and ecotourism, so that the National System of Unit Conservation (Sistema Nacional de Unidades de Conservação) SNUC (Law 9.985/2000) covers the practice of touristic activities, specially the ecotourism in these territorial unities. Despite these are areas for environmental conservation, practice of environmental education, scientific research and contemplation of the nature in its primary or in a similar condition, the practice of touristic activity does not often meet these aims. The main aim of this research was to evaluate the touristic activities and the actions of territorial management in the State Park of Pedra da Boca (PEPB), situated in the city of Araruna/PB. According to the results, the PEPB has in its territorial area a porphyritic granite rock set, whose geological and geomorphologic settings are unique and have scenic value. It is also home of flora and fauna endemic species and representative of the savanna biome. The data and information achieved show that the Park has a remarkable potential for tourism, especially ecotourism, however, there is a need for development of territorial management actions, in order to subsidize the use of spatial tourism site

Spectral analysis of flowers used by nectar-feeding birds in an urban area in Southeastern Brazil

Análise espectral de flores utilizada por aves nectarívoras em áreas urbanas. O objetivo deste trabalho foi estabelecer a característica espectral das flores produtoras de néctar visitadas por nectarívoros em áreas urbanas. Este estudo foi desenvolvido na região central do município de Taubaté, no nordeste do Estado de São Paulo. As áreas amostradas incluíram espaços verdes, tais como praças e parques e a vegetação das ruas e avenidas. Foram registradas 12 espécies de plantas utilizadas por cinco espécies de aves nectarívoras. As espécies de flores mais visitadas foram aquelas que refletiram em comprimento de onda longos (>600 nm). Foi discutida a capacidade de detecção das aves em função de visão tetracromática das aves nectarívoras e da conspicuidade das flores em ambientes urbanos. Finalmente, foi abordado o problema da escassez de plantas atrativas para aves nectarívoras nas áreas verdes urbanas e a necessidade de se aumentar a quantidade dessas espécies de plantas para incrementar a biodiversidade em regiões urbanas.
