O ecoturismo é considerado uma atividade geralmente de baixo impacto ambiental, orientado às localidades onde haja área de significativo valor ambiental e cultural. E, que pode, conforme suas atividades recreacionais e educativas, contribuir para a conservação da biodiversidade e sociodiversidade local. Neste sentido, o conceito de ecoturismo é apresentado como visita a ambientes naturais, tendo o mínimo de impacto por seus visitantes sobre a diversidade local. Exemplo disso é Jericoacoara, localizado à 320 km da capital Fortaleza (CE), onde sua diversidade, como um todo, é extremamente propícia a este segmento do turismo. Nele, se destaca o Parque Nacional de Jericoacoara (PNJ) apresentando uma área de 8.850,00 hectares que abrange oito ecossistemas. O objetivo deste trabalho é descrever a percepção dos discentes do Curso de Turismo da Universidade Federal do Pará (UFPA) a partir da visita técnica, como parte de suas atividades acadêmicas desenvolvidos durante o curso. A metodologia utilizada foi a partir da aplicação de questionário com perguntas semiestruturada e fechadas. Este foi direcionado à trilha realizada no PNJ. O público-alvo foram 27 discentes do Curso de Turismo da Universidade Federal do Pará (UFPA). A visita técnica foi realizada no mês de novembro de 2015. Após a coleta dos dados, estes foram inseridos na planilha do Office Excel. Posteriormente, os dados foram tabulados em valores absolutos, seguidamente calculados os valores relativos. Os resultados apontam que a maioria dos discentes nunca realizaram uma trilha, e informaram que a principal dificuldade encontrada durante a caminhada foram a elevada temperatura e o percurso longo. Dentre o principal aspecto natural que mais chamou a atenção foi a vegetação local, e que o local oferece risco de acidentes durante o percurso. Com relação ao lixo e saneamento local, a maioria informou que não percebeu nada de anormal durante a caminhada na trilha. Porém, com relação aos ruídos e vandalismo, as respostas foram positivas. E, para finalizar os discentes responderam que, do ponto ecoturístico, o local é bom para o desenvolvimento deste segmento. Deste modo, concluiu-se que os discentes do Curso de Turismo da UFPA apresentam boa percepção da trilha do PNJ, uma vez que durante o percurso a observação para diversos aspectos foram notadas, sejam elas positivas ou negativas; comprovando deste modo que o trabalho teórico realizado durante o curso tem aguçado a percepção dos discentes durante essas vistas técnicas. The perception of the Jericoacoara National Park by UFPA tourism students ABSTRACT Ecotourism is considered a low environmental impact activity, guided to locations where there is area of significant environmental and cultural values. And it can contribute to the conservation of local biodiversity and social diversity, due to its recreational and educational activities. In this direction, the concept of ecotourism is presented as visiting natural environments, having minimal visitor impact on local diversity. An example of this is Jericoacoara, located 320 km from the capital Fortaleza (CE), where its diversity is extremely favorable to tourism activities. Inside of it, is also located the Jericoacoara National Park (JNP) an area of 8850.00 hectares consisting of eight ecosystems. The objective of this study is to describe the perception of tourism students of Federal University of Pará (UFPA), based upon a technical field trip, as part of their academic activities developed during their coursework. The methodology included a questionnaire with semi-structured and closed questions, which was applied during the trail at the JNP. The audience was 27 tourism students of UFPA. The field trip took place in November 2015. The collected data were inserted in the Excel Office spreadsheet, then tabulated and calculated their absolute and relative values. The results indicate that most of the students never walked on a trail and they reported that the main difficulties encountered during the walk were high temperature and the long itinerary. The natural aspect that drew the most attention was the local vegetation, but the environment offers risk of accidents during the itinerary. Regarding the waste and local sanitation, most of the students said that they did not see anything unusual while walking on the trail. However, with regard to noise and vandalism, the answers were affirmative. Finally, the students answered, based upon ecotourism perspective, that the area is adequate to the development of this activity. Thus, it was concluded that the students have a good perception of the JNP trail, because during the walk observations of many aspects were noted, whether positive or negative, proving thereby that the theoretical study done during the coursework has sharpened the perception of students during the field trip.

Six major rivers flow through the Kruger National Park (KNP). All these rivers originate outside and to the west of the KNP and are highly utilized. They are crucially important for the conservation of the unique natural environments of the KNP. The human population growth in the Lowveld during the past two decades brought with it the rapid expansion of irrigation farming, exotic afforestation and land grazed by domestic stock, as well as the establishment of large towns, mines, dams and industries. Along with these developments came overgrazing, erosion, over-utilization and pollution of rivers, as well as clearing of indigenous forests from large areas outside the borders of the KNP. Over-utilization of the rivers which ultimately flow through the KNP poses one of the most serious challenges to the KNP's management. This paper gives the background to the development in the catchments and highlights the problems which these have caused for the KNP. Management actions which have been taken as well as their results are discussed and solutions to certain problems proposed. Three rivers, namely the Letaba, Olifants and Sabie are respectively described as examples of an over-utilized river, a polluted river and a river which is still in a fairly good condition.

Slightly alkaline hot springs and geysers in Yellowstone National Park exhibit distinctive assemblages of high-temperature (>73 °C) siliceous sinter reflecting local hydrodynamic conditions. The main depositional zones include subaqueous pool and channel bottoms and intermittently wetted subaerial splash, surge, and overflow areas. Subaqueous deposits include particulate siliceous sediment and dendritic and microbial silica framework. Silica framework forms thin, porous, microbe-rich films coating subaqueous surfaces. Spicules with intervening narrow crevices dominate in splash zones. Surge and overflow deposits include pool and channel rims, columns, and knobs. In thin section, subaerial sinter is composed of (i) dark brown, nearly opaque laminated sinter deposited on surfaces that evaporate to dryness; (ii) clear translucent silica deposited subaqueously through precipitation driven by supersaturation; (iii) heterogeneous silica representing silica-encrusted microbial filaments and detritus; and (iv) sinter debris. Brownish laminations form the framework of most sinter deposited in surge and overflow zones. Pits and cavities are common architectural features of subaerial sinter and show concave-upward pseudo-cross-laminations and micro-unconformities developed through migration. Marked birefringence of silica deposited on surfaces that evaporate to dryness is probably a strain effect. Repeated wetting and evaporation, often to dryness, and capillary effects control the deposition, morphology, and microstructure of most high-temperature sinter outside of the fully subaqueous zone. Microbial filaments are abundant on and within high-temperature sinter but do not provide the main controls on morphology or structuring except in biofilms developed on subaqueous surfaces. Millimetre-scale lamination cyclicity in much high-temperature sinter represents annual layering and regular seasonal fluctuations in silica sedimentation.

ABSTRACTRates of dissolved inorganic carbon (DIC), formate, and acetate mineralization and/or assimilation were determined in 13 high-temperature (>73°C) hot springs in Yellowstone National Park (YNP), Wyoming, in order to evaluate the relative importance of these substrates in supporting microbial metabolism. While 9 of the hot spring communities exhibited rates of DIC assimilation that were greater than those of formate and acetate assimilation, 2 exhibited rates of formate and/or acetate assimilation that exceeded those of DIC assimilation. Overall rates of DIC, formate, and acetate mineralization and assimilation were positively correlated with spring pH but showed little correlation with temperature. Communities sampled from hot springs with similar geochemistries generally exhibited similar rates of substrate transformation, as well as similar community compositions, as revealed by 16S rRNA gene-tagged sequencing. Amendment of microcosms with small (micromolar) amounts of formate suppressed DIC assimilation in short-term (<45-min) incubations, despite the presence of native DIC concentrations that exceeded those of added formate by 2 to 3 orders of magnitude. The concentration of added formate required to suppress DIC assimilation was similar to the affinity constant (Km) for formate transformation, as determined by community kinetic assays. These results suggest that dominant chemoautotrophs in high-temperature communities are facultatively autotrophic or mixotrophic, are adapted to fluctuating nutrient availabilities, and are capable of taking advantage of energy-rich organic substrates when they become available.

Organosulfur compounds show a negative environmental impact because of SOx emissions by combustion of fuel oils. As a consequence, removal of sulfur is becoming a worldwide challenge. The hydrodesulfurization (HDS) process achieves limited performances in the case of refractory S-containing aromatic compounds, such as thiophene and substituted benzothiophenes (BTs), which require highly energy-demanding conditions (high temperature and pressure conditions). Oxidative desulfurization (ODS) is considered the most promising alternative to HDS. During ODS treatment, the organosulfur compounds are oxidized to corresponding sulfoxides and sulfones, which can be successively removed by extraction with polar solvents. Different stoichiometric oxidants have been used in the ODS processes with a different degree of efficacy and environmental impact. The design and development of catalytic procedures can increase the ODS energy efficiency as well as make it more economical and environmentally acceptable. Here we describe the advances in nanostructured organometallic catalysis and biotechology applied to ODS treatment.

The purpose of this study is to find a picture of the involvement of Indigenous Peoples of Tabi Mamta in the process of environmental impact assessment (EIA) in Tabi Mamta customary territory. The method and type of research used is non-ethnographic qualitative research with data collection techniques using limited observation techniques. Data and information in the field will be analyzed using constructivism paradigm. The paradigm of constructivism is based on an interpretive understanding called hermeneutics (hermeneuien) in the sense of interpreting, giving understanding, translating data and information obtained in the research location as a result of social reality. The results of this study indicate that the customary community of Tabi Mamta is a unit of customary community that still has territorial customary territory, has a customary leadership structure, still visible relationship of kinship, cultural values as well as customary norms and sanctions, and has environmental wisdom in maintaining existence Natural resources. In the socio-cultural system of customary communities there are components such as customary stratification, permissiveness, communication, reciprocity, past history, cultural values, customary norms and sanctions, religious and customary leadership. Components in the socio-cultural system of indigenous and tribal peoples play a role in the EIA process in the Tabi Mamta customary area especially in the environmental feasibility decision making process. The components of custom stratification, cultural values and customary norms play a role in the EIA process. In customary stratification there is uncustomary structure in the ondoafi, Iram and Tribal Leadership. Components in a sociual cultural system is a unity resulting from interaction between individuals and groups to prevent environmental damage and disturbance of natural resources. Natural resources are considered as ancestral symbols passed down by ancestors from generation to generation
