Visceral leishmaniasis hás adapted in the past 20 years to periurban and urban areas, and in Natal, Rio Grande do Norte, it became endemic. Thid study aimed to evaluate the environmental and social aspectsof Leishmania chagasi infection and its epidemiologic transmission chain in an urban, periurban and rural area of Parnamirim-RN. A study with three sections was conducted: Section 1: Sectional study of the human and canine infection by L. chagasi and its environmental and social determinants. Section 2: Observational longitudinal cohort to evaluate the dynamics of the canine infection. Section 3: Longitudinal study to evaluate the behavior of Lu. Longipalpis vector and the seasonal factors related to its dynamics. To include in the study the hauses were randomly selected and georreferenciated. Montenegro skin test was done in the human population and blood samples were collected for anti-Leishmania antibody detection. The canine population was examinated for L. chagasi infection by RIFI, ELISA and ELISA for rK39. An entomologic surveillance was monthly done with CDC light trapsin 10 houses of each locality. Quantitative and qualitative analyses was done using STATISC 6.0. Probality and prediction maps were done using ArcGis 9.0 model. In the human population L. chagasi infection was associated with the area of the hause, age, sex, population densyti, vegetation, kind of the floor of thr hause, water and resides destiny. In the canine population L. chagasi infection was associated with the breed, size, time of living in the hause, presence of dogs in the neighborhood, presence of horses and donkeys in the neighborhood, vegetation, kind of the floor and walls of the hause. The human infection was associated with canine infction only when analyzed taking into account the locality. In the prospective study, serum conversion and antibody lost observed in 30,8% and 22% of the animals examined, respectively. The human infection rate by L. chagasi was 24,6%, by the presence of anti-Leishmania antibody and 38,6% by the Montenegro skin test. The canine infection rate 32,5% by the presence of anti-Leishmania antibody. The vector Lu longipalpis showed an atypical behavior. These results indicate that environmental and social factors are important variables associated with L. chagasi infection in humans and canines, with punctual association of thr last two. Control measures of the infection on the studied points are necessary, in the aim to reduce the endemic focus of the disease in the study area. This research was carried out in a multidisciplinary involving the categories of: doctor, biologist, veterinarian, statistical, pharmaceutical and biochemical

The present work aimed the elaboration of an environmental study focused on the hotel sector in order to present an analysis of the environmental aspects of Ponta Negra Beach, in Natal, RN, Brazil and also the aspects of the small and medium hotels existing in this area. By means of this work, it is possible to elaborate a model of a simplified System of Environmental Management which can attend to the exigencies required by NBR ISO 14001: 2004, as well as to present economical viability and possibility to be implemented in a way that hotels may converge to the sustainable environmental development of the tourism in Ponta Negra Beach. The research methodology presents itself divided into three items: execution of the environmental characterization of Ponta Negra Beach, by way of technical visits and interpretation of satellite images and cartograms of the main environmental characteristics of the region; execution of the work already made concerning the development, application and interpretation of the evaluation of the environmental aspects of each hotel, considering the hotels and the period of data collection, these used in evaluation, research instrument and a description of the procedure utilized for the analysis of the collected data and the utilized methodology for the elaboration of a model of a simplified System of Environmental Management. In a general way, it has been concluded that the practices executed by hotels in Ponta Negra Beach are impact-like and harmful to the environment. The simple implementation of analysis procedures and control of the environmental aspects could suggestively contribute to the reduction of environmental impacts promoted by the hotel section at this beach and in the nearby areas. It had been noticed that the study contributed to the sensitization of managers concerning the environmental problems since, in many other times, the detected problem was, in fact, the non-acquaintance about the environmental aspects and impacts from those hotels administrators, because of the lack of surveys and studies about the theme. It had also been noticed the arousing of a possible environmental attitude from some managers

The aerial activities, leaps and slaps with parts of the body in the surface of water, are part of the behavioral repertoire of several species of cetaceans. Among them, the spinner dolphin, Stenella longirostris, shows greater diversity in such behavior. For the spinner dolphins of Fernando de Noronha, the aerial activities are classified as vertical and horizontal, with eight patterns to be noted (tail slap, head slap, motor boating, partial leap, leap, spin, tail over head and tail over head with spin) discriminated between these categories. Such behaviors can be used as a parameter to identify behavioral changes, as well as patterns of daily and seasonal activity. In this manner, this study aimed to characterize the frequency in performance of such activity while the dolphins were within the Dolphin Bay of Fernando de Noronha, and verify possible daily and seasonal hourly fluctuations on such behaviors. The data analyzed in this study was acquired during the period of January 2006 through December 2010, totaling 1431 days of observation from land set point, with 113027 aerial activities registered, daily average of 72,27 (SD=96,10). During 5478h and 54 min of observation the horizontal aerial activity was the most observed and rotation was the most executed pattern. Greater frequency of execution of aerial activity was observed in adults, but for both adults and calves, was observed a predominance of horizontal activities, with spin being the pattern most executed. Positive correlation was observed between the amount of aerial activity performed and the number of animals inside the Bay. Hourly daily fluctuation was observed in the expression of aerial activities by spinner dolphins, and was observed a peak of activity between 8h and 8h59min for the overall frequency relative of aerial activities, as well as for the categories and patterns. Seasonal differences were observed between the rainy and dry season with the greater amount of activity being observed during the rainy season. Nevertheless, the same profile of frequency relative of aerial activity was observed in both seasons with the peak amount being during the same period. When discriminated the aerial activities in categories and patterns, for both seasons, there was a similar pattern of hourly fluctuation; for most of parameters, higher frequency relative of execution of aerial activity remain between 8h and 8h59min

This work evaluates the impact of the pink shrimp Farfantepenaeus paulensis (Perez-Farfante, 1967) fishery on fish and crab assemblages of Lagoa do Peixe National Park, Brazil. We observed that composition of catches is similar to shrimp fisheries using fyke-net at others estuaries of Rio Grande do Sul State: pink shrimp (53%), accessory catches (24%) and bycatch (23%). However, fishery composition showed distinct differences along the saline gradient of the main park's lagoon. Regarding only fish species, the most impacted species in this fishery were Brevoortia pectinata (Jenyns, 1842), Micropogonias furnieri (Desmarest, 1823), and Jenynsia multidentata (Jenyns, 1842). In others estuaries from Rio Grande do Sul, in contrast, the most impacted species were M. furnieri, Genidens barbus (Lacepède, 1803) and Genidens genidens (Cuvier, 1829). The potential impact of the pink shrimp fishery at Lagoa do Peixe National Park seemed to be weaker when compared to shrimp fisheries elsewhere. We believe that the decision to prohibit this fishery at the Lagoa do Peixe National Park should not be based on its potential damage to the fish and crab assemblages but based on the simple fact that Brazilian laws do not allow fisheries inside National Parks.

Este trabalho de pesquisa analisou o turismo no entorno do Parque Nacional do Cabo Orange, no estado do Amapá. Para isso, utilizou-se de um enfoque qualitativo para compreender a realidade das duas comunidades residentes nesse entorno, Vila Velha do Cassiporé e Vila Cunani e suas percepções acerca de turismo, bem como entender o papel das principais instituições governamentais e não-governamentais que tentam implementar políticas de desenvolvimento nesse Parque Nacional. Diante disso, verificou-se que as políticas públicas direcionadas para o entorno dessa unidade de conservação ainda são incipientes, assim como há uma visível fragmentação do tecido social dessas duas comunidades tradicionais residentes. Ademais, percebeu-se que existem potencialidades naturais, históricas e culturais que podem ser trabalhadas no fomento de produtos turísticos, entretanto, ainda não há um trabalho voltado para tal fim. Portanto, concluiu-se que os limites são maiores do que as possibilidades no desenvolvimento do turismo nesse entorno do Parque Nacional do Cabo Orange. Dessa maneira, cabe às instituições competentes e comunidades residentes desse entorno exercitarem a participação como garantia de sustentabilidade para que o turismo possa a vir a ser uma possibilidade de inclusão social, desenvolvimento e indutor de conservação dos recursos naturais e culturais dessa unidade de conservação de uso integral no norte do estado do Amapá.
