Diversidade de paronellidae (collembola, arthropleona, entomobryoidea) no nordeste brasileiro, com ênfase em áreas úmidas da caatinga

Paronellidae is among the most diverse and distinctive components of epiedaphic Collembola in tropical countries. However, only 15 species of the family were recorded in Brazil, and only two of them were record in northeast region of the country. This condiction is clearly related to low sampling efforts and lack of specialists working with the group. Due to this reality, this work aimed to study the Paronellidae fauna, under a taxonomic point of view, in six distinct environments in Northeastern Brazil (from Alagoas, Bahia, Ceará, Piauí and Paraíba states), five areas of Caatinga and one from Atlantic Rain Forest biome. Collections were made during the rainy season on each area. The specimens were analyzed under stereomicroscope and mounted in glass slides for microscopy. The specimens identified as Paronellidae had their occurrence recorded and five new species were described. An identification key to the brazilian genera of the family was also prepared. Twelve species of Paronellidae were recorded for the first time to Brazil: Campylothorax mitrai; Lepidonella. sp. nov. 1; Lepidonella sp. nov. 2, Lepidonella sp. nov. 3, Lepidonella sp. nov 4, Lepidonella sp. nov. 5; Dicranocentruga sp. Nov. 1; Dicranocentruga sp. Nov. 2; Dicranocentruga sp. Nov. 3; Paronella sp. nov.1; Serroderus sp. nov.1 and Trogolaphysa. sp. 1, where C. mitrai, Lepidonella. sp. nov 1, Dicranocentruga sp. nov 1, Dicranocentruga sp. nov 2 and Dicranocentruga sp. nov 3 were described. Serroderus and Dicranocentruga genera were recorded for the first time to Brazil. The description of Lepidonella sp. nov 1 also represents the first description of a species of the genus for the country. The data presented show a high potential species richness to Paronellidae, not only in the northeast region, but as in Brazil. In fact, with the records presented in this work, the number of recorded species of Paronellidae in the country increased by 80%. The study of this particular fauna may direct environmental conservation policies, especially in areas of Caatinga

Participação social e designação de espécie-bandeira: ações complementares à conservação de um parque estadual em área urbana

Facing environmental problems the planet appears several alternative preventive and control on behalf of the equation between development and environmental protection. One of the alternatives implemented in Brazil to conservation of biodiversity was the creation of protected natural areas regulated by the National System of Conservation Units (SNUC). This is an integrated study of the Comunication / Environmental Conservation, which prioritizes social participation as a complementary in the conservation process, the particular case of the Dunas do Natal State Park, the first conservation area in Rio Grande do Norte, for full protection. It takes into account the roles environmental, scientific and Park, which harbors a unique biodiversity, including endemic species and the fact being located in an urban area. It proposes the use of two complementary instruments, such as strategies for conservation. Considering the various individual experiences, it was analyzed the perception that the community is directly related to the Park. From this promoted the democratization of information about the park, its biodiversity and conservation. As another conservation tool, it was suggested the use of a flagship species for the park, or a body chosen symbol for environmental or social reasons, in order to protect and conserve certain natural environments, from the understanding and co -community participation. In this case, as proposed flag Coleodactylus natalensis species, the lizard-the-litter, to be endemic remnants of Atlantic Forest Park as having the type locality, be one of the smallest species of the world, South America's lowest-dependent shadow of the forest, sensitive to human action and therefore very vulnerable. This suggestion finds support in the degree of public acceptance that interacts directly with the Park, as a result of the evaluation of their perceptions. It was further observed in this study that this symbology to be used in order to promote the democratization of the Park and its biodiversity has an identification result, curiosity and probable involvement of the population with the issues of the Park

Estudo das percepções ambientais e de ações educativas promotoras da biodiversidade em unidade de conservação no Rio Grande do Norte

Important issues involving the awakening to the need for conservation of biodiversity and the importance of establishing protected areas as a strategy in pursuit of environmental protection, are increasingly being developed in biological and social investigative fields. In this sense, this research aimed to emphasize the use of environmental perception of social agents are significant elements for the understanding of the man / nature, and develop educational activities aimed at raising awareness and changing attitudes towards environmental issues thus promoting reflections on Environmental Education (EE) as a critical and transformative tool for conservation of rich biological diversity. This research covers as a place of study, schools located in the Environmental Protection Area Jenipabu (APAJ), Rio Grande do Norte. Methodology in general, we highlight the use of questionnaires and mind maps as generators of the contents of empirical research, and execution of content analysis for the treatment of data collected. This dissertation has two chapters in the form of scientific articles, where the first is entitled: "Study of the perceptions and evaluation of interactions concerning environmental education in schools in a conservation area of Rio Grande do Norte - Brazil", obtaining thus a primary diagnosis for analysis about the visions that students and teachers from two schools located in APAJ have on the environment. The second article, entitled: "Effective and analysis of educational activities that promote biodiversity in a coastal area of Environmental Protection Northeast - Brazil" provides an analysis of the educational use of biodiversity as a way to raise awareness of the need for environmental conservation. It appears from research that there is a lack of training in EA by teachers, but there is a need for greater involvement of students in conservation areas, however, from the analysis of educational activities, we observed that the effectiveness of such actions acts to promote awareness and change in actors involved. Thus, environmental education needs to take into account the different perceptions found in each individual, and it can not be based solely on transmission of knowledge, so that we reach a model of conservation.

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

Percepções ambientais de comunidades rurais e indicadores de sustentabilidade como subsídios à conservação de áreas de caatinga no Rio Grande do Norte

Environmental degradation is a global problem that particularly affects areas subject to seasonal climatic variations, such as the brazilian semiarid region, namely the Caatinga Domain. Combined with other negative factors, such as natural resource misuse and disorderly land occupation, the consequences of Environmental Degradation have challenged science in the quest for addressing the resulting social and environmental problems. Accordingly, Environmental Perception methodology, by analyzing the concepts, attitudes and values, (especially those pertaining to environmental conservation) represent an important tool in studies that address the relationship between the environment and human actions. Sustainability Indicators are also relevant tools to assess the possible causes and consequences of environmental problems. Among several Sustainability Indicators available, the PressuresState-Impact-Response (PSIR) method is an analytical tool that permits the grouping of factors affecting sustainability as well as their consequences for nature and human health, and thus indicate mitigating actions for society and the public authorities. From this perspective, three areas of Caatinga were studied in Rio Grande do Norte state: Seridó Ecological Station (ESEC), Municipality of Serra Negra do Norte; Private Natural Reserve Stoessel de Brito (PNRSB), Municipality of Jucurutu; and part of the Serra de Santana, Municipality of Tenente Laurentino Cruz. The areas are both legally protected and unprotected and subject to diferent management protocols, though their share the common characteristic of human misuse of natural resources. In this scenario, this thesis´ main goal was to introduce the rural communities into the conservation process, using the results of Environmental Perception of such communities, combined with the analysis of the sustainability of municipalities through PSIR. Information on Environmental Perception was obtained from primary and secondary data from previous studies carried out in the ESEC Seridó and PRNP Stoessel de Brito. Additional data was obtained through direct observation and interview forms applied to rural communities in the Municipality of Tenente Laurentino Cruz. The results showed that respondents possessed a broad knowledge regarding environmental degradation, its causes and consequences for the caatinga biome. PEIR analysis showed that environmental degradation was smaller in countries with protected areas, as compared to those without. The population´s knowledge about environmental degradation and their acceptance of conservation units, as showed by Environmental Perception Analysis, coupled with the results of PEIR, suggest that those attitudes may foster actions aimed at reduction of environmental degradation in the Caatinga domain
