In Brasil, the current policy attention to alcohol, crack and other drugs has created a network of services that operates on the principles of harm reduction and psychosocial care. One of the strategic points of attention in this network are the Psychosocial Care Centers for Alcohol and Other Drugs 24 (CAPS ad 24), where the night host is presented as a core technology of care to people who have attention needs due the use of substances. And as in Maceio, there was the recent deployment of this service, broke the following question: How would be getting on the experience of night shelter in CAPSad 24? To answer it was set a goal: to understand the experience of people in night shelter in a CAPSad 24. To reach it was developed this descriptive exploratory study with a qualitative approach. The information was produced by interviewing the subjects who experienced the night shelter in the service, systematic observation and field notes. The information was analyzed using content analysis method proposed by Bardin (2011), supplemented by the records of observation and field. The survey results revealed that the search for service occurred before the perceived need for help due to the loss of control over drug use, for damages caused in this condition and for being on the streets, indicated that this search was given by free will is sometimes encouraged by family and professional network of mental health. The evening reception was well evaluated both arrival and the permanence of users in the service, on arrival they described fast service that has always been done by the multidisciplinary team. About staying in the service, conversation and interpersonal relationships were seen as host of the facilitators, clinical care were present in every speech. The group activities were shown to be the most used in the service, some were well evaluated and others have been criticized. Proved necessary diversification and promotion of therapeutic activities as well as investment in physical infrastructure, material resources and continuing education for professionals. The change components of the multi professional team with the policy management transition had a negative impact reported by most respondents. The night shelter in CAPSad 24 was superior when compared to internment experiences in therapeutic communities and psychiatric hospitals. He highlighted the constant presence and availability of nursing professionals, especially in clinical care and opportunities for dialogue. / No Brasil, a atual política de atenção ao álcool, crack e outras drogas vem tecendo uma rede de serviços que atua nos princípios da redução de danos e da atenção psicossocial. Um dos pontos estratégicos de atenção desta rede são os Centros de Atenção Psicossocial para Álcool e outras Drogas 24h (CAPS ad 24h), em que o acolhimento noturno apresenta-se como modalidade de atenção às pessoas que apresentam necessidades decorrentes do uso de substâncias. Em Maceió, houve a implantação recente deste serviço, e, tendo em vista a necessidade de melhor conhecê-lo, nesta pesquisa foi elaborada a seguinte pergunta: Como se dá a vivência de acolhimento noturno em CAPSad 24h? Para respondê-la foi estabelecido como objetivo: compreender a vivência de pessoas em acolhimento noturno em um CAPSad 24h. Para tanto, desenvolveu-se esta pesquisa de caráter descritivo exploratório com abordagem qualitativa dos dados. As informações foram produzidas através de entrevistas aos sujeitos que vivenciaram o acolhimento noturno no serviço, observação sistemática e notas de campo realizadas pela pesquisadora. As informações foram analisadas segundo o método de análise de conteúdo proposto por Bardin (2011), subsidiadas pelos registros de observação e campo. Os resultados da pesquisa revelaram que a busca pelo serviço se deu diante da percepção da necessidade de ajuda decorrente da perda de controle sobre o uso da droga, pelos prejuízos causados nessa condição e por estarem em situação de rua, referiram que essa busca se deu por livre e espontânea vontade sendo por vezes estimulada pela família e por profissionais da rede de atenção em saúde mental. O acolhimento noturno foi avaliado positivamente tanto na chegada quanto na permanência dos usuários no serviço, na chegada descreveram rapidez no atendimento que foi sempre realizado por equipe multiprofissional. Sobre a permanência no serviço, a conversa e o relacionamento interpessoal foram tidos como facilitadores do acolhimento, os cuidados clínicos estiveram presentes em todos os discursos. As atividades grupais mostraram-se como as mais realizadas no serviço, algumas foram avaliadas de forma positiva e outras foram criticadas. Mostrou-se necessário a diversificação e dinamização das atividades terapêuticas bem como investimento em estrutura física, recursos materiais e de formação continuada para os profissionais. A mudança de profissionais componentes da equipe multiprofissional com a transição de gestão política gerou impacto negativo relatado pela maioria dos entrevistados. O acolhimento noturno em CAPSad 24h mostrou-se superior quando comparado às vivências de internação em comunidades terapêuticas e hospitais psiquiátricos. Destacou-se a constante presença e disponibilidade dos profissionais de enfermagem, principalmente em cuidados clínicos e possibilidades de diálogo.

As Unidades de Conservação (UC) são espaços territoriais com características naturais relevantes, que têm a função de assegurar a representatividade de amostras significativas e ecologicamente viáveis das diferentes populações, habitats e ecossistemas. A Legislação Brasileira instituiu no ano de 2000 o Sistema Nacional de Unidades de Conservação da Natureza (SNUC). Dentre os diversos ambientes encontrados em território nacional, o Pampa tem uma representatividade de apenas 0,4% de sua área protegida, conforme consta no SNUC. O Refúgio da Vida Silvestre Banhado dos Pachecos (RVSBP) é uma UC de proteção integral estadual, localizada no Rio Grande do Sul e no Bioma Pampa, com uma área de 2.560 ha e representa cerca de 3,5% de todas as UC’s de proteção integral desse bioma. O RVSBP criada no ano de 2002, e ainda não possui plano de manejo, bem como carece de maiores investimentos e atenção. O uso de imagens de satélites como subsídio aos estudos ambientais já está consolidado e a interpretação destas imagens, a partir de diversos métodos, para classificar o uso e cobertura da terra, tem se tornado uma constante, munindo os pesquisadores de informações dos diversos processos que possam estar ocorrendo em uma determinada área de estudo, inclusive monitorando as mudanças ao longo do tempo. Os objetivos desta dissertação são os de verificar as mudanças no uso e cobertura do solo ocorridas entre 2001 e 2017 no RVSBP e em seu entorno direto de 10km, baseando-se na análise de imagens de satélite. Para tanto serão mapeadas as classes de uso e cobertura do solo, a partir de imagens dos satélites LANDSAT 5 – Sensor TM, LANDSAT 7 – Sensor ETM+ e LANDSAT 8 – Sensor OLI, para os anos de 2001, 2009 e 2017. O método de detecção das mudanças no uso e cobertura do solo aplicada foi a técnica de comparação pós-classificação para uma melhor compreensão das interações entre os fenômenos naturais e as atividades humanas. Essa técnica foi aplicada para os períodos de 2001 a 2009, de 2009 a 2017 e de 2001 a 2017. Para o período de 2001 a 2009 as mudanças ocorreram em 17,5% da área de estudo e em 19,9% do RVSBP. Para o período de 2009 a 2017 as mudanças ocorreram em 22,8% da área de estudo e em 23,9% do RVSBP. Para o período de 2001 a 2017 as mudanças ocorreram em 24% da área de estudo e em 32% do RVSBP. Dentre esses 32% a classe que apresentou os maiores acréscimos de área foram as classes de Agricultura – Arroz e de Associação de Sítio e produtores rurais, que respectivamente compreendem áreas de 410 hectares e de 135 hectares. As classes que foram mais impactadas com perda de área foram as classes Banhado e Vegetação Arbórea, que respectivamente compreendem áreas de 435 hectares e de 173 hectares. A análise de detecção de mudanças se mostrou efetiva como uma forma de monitoramento sistemático do uso e cobertura do solo do RVSBP e entorno, trazendo elementos importantes para a gestão da UC. / Conservation Units (UC) are territorial spaces with relevant natural characteristics, which have a role of ensuring the representativeness of significant and ecologically viable samples of different populations, habitats and ecosystems. Brazilian legistlation established in 2000 the National System of Nature Conservation Units (SNUC). Among the several environments found in the national territory, the Pampa has a representation of only 0,4% of its own protected area, according to SNUC. The Wildlife Refuge Banhado dos Pachecos (RVSBP) is a state UC of integral protection, located in Rio Grande do Sul and Bioma Pampa, with 2.560 ha and comprises about 3,5% of all integral protection UC of this biome. RVSBP was created in 2002, still does not have a management plan, and lacks greater investments and attention. The use of satellite images to suppott environmental studies is already consolidate and the interpretation of these images, using different methods, to classify land and use cover, has become a constant, providing researchers with information on the various processes that may be occurring in a particular study area, including monitoring changes over time. The objective of this dissertation is to verify the changes in the land use and cover occurred between 2001 and 2017 in RVSBP and in its surrounds of 10km, based on the analysis of satellite images. Therefore, the land and use coverage classes were mapped using images from the LANDSAT 5 - Sensor TM, LANDSAT 7 - ETM + and LANDSAT 8 - OLI Sensor, for the years 2001, 2009 and 2017. The method of detecting changes in land use and cover was the post-classification comparison technique for a better understanding of the interactions between natural phenomena and human activities. This technique was applied for the periods from 2001 to 2009, from 2009 to 2017, and from 2001 to 2017. For the period 2001 to 2009 the changes occurred in 17,5% of the whole study area and in 19,9% of RVSBP. For the period from 2009 to 2017, changes occurred in 22,8% of the whole study area and 23,9% of RVSBP. For the period from 2001 to 2017, changes occurred in 24% of the whole study area and 32% of RVSBP. Among these 32%, the class with the greatest increases in area were Agriculture – Rice crops and Site Association of Rural Producers, which respectively comprises areas of 410 hectares and 135 hectares. The classes that were most impacted with loss of area were the class Weands and Arboreal Vegetation, which respectively comprise areas of 435 and 173 hectares. The change detection analysis was effective as a way of systematically monitoring the land use and coverage of RVSBP and surroundings, bringing important elements to the management of the UC.

In November 2016 the Swedish government requested a study where actions were suggested in order to strengthen the children's rights perspective for those children living at refuges. This resulted in the commission of inquiry "A window of opportunity- a strengthen children's rights perspective for children in refuges" (SOU 2017:112). The aim for this paper is to study how this inquiry is constructed and in which way it problematize children's rights and will be guided by three research questions: how is the concept ‘children's rights' problematized in the report SOU 2017:112, how does the problematization of children's rights position children living at the refuges in order to strengthen them as rights holders and what implicit assumptions are made as a way to increase the children's rights perspective for the children living at refuges? To investigate these questions this paper will do a policy analysis based on Carol Bacchi’s (2009) “What’s the Problem Represented to Be?” (WPR) approach. The method is chosen since the WPR-approach is used for the study of policies and especially studies the way a policy constructs a problem. This paper argues that the problematization of children's rights positions the children at the refuges as in need of protection and care and at the same time emphasizes their right to get their voice heard, as they are being active individuals. The urge to strengthen the children is argued to be a way to prevent the children who have experienced violence to become abusive themselves. As such, the conclusion is that a strengthen children's rights perspective for those children living in refuges transmits to them becoming ‘good citizens'.

The effectiveness of these protected areas is determined by the social actors involved in the unit and its surroundings. Only in the Cerrado, there are 386 protected areas covering the entire biome in different socio-economic and environmental contexts. The northern portion of this biome is under intense pressure for the intensification of the conversion of the Cerrado by agribusiness, which has been enhanced since the creation of the MATOPIBA region. In the western Bahia Plateau, this expansion has been specifically polarized by the municipalities of Luiz Eduardo Magalhães and Barreiras, and has been intensified in the last 15 years with the consolidation of irrigation projects by central pivots. In 2000, the federal government created the Refugio de Vida Silvestre Veredas do Oeste Baiano (RVSVOB) in this region to fully protect a habitat of the loon duck (Mergus octosetaceus). Its geographic boundaries follow roughly the layout of the enclosed valley of the Pratudinho River and the high valley of the Pratudão River, including, at its extreme east, a part of dissected hills. Despite being protected, the area and its ecological function have suffered from the impacts of anthropogenic pressures from the plateaus (exploitation of water for the projects and central-pivot installation, e.g.) and in the enclosed valleys (burnings, grazing, accelerated erosion, e.g.). Due to these problems and the strict relation that the UC has with the superficial water resources, the effectiveness of the RVSVOB can be put in checkmate. In this context, it is proposed to evaluate the effectiveness of this PA through of the analysis and modeling of analogous space-time environmental systems. Therefore, the adjacent watersheds were chosen in the north - Veredãozinho River - and in the south - the Formoso River - whereas similar areas to the RVSVOB were delineated for comparative analysis of the most important elements and flows in the ecological function of this PA. The analysis units adopted were: (i) watershed, (ii) watershed segments (high, medium and low), (iii) RVSVOB and its similar areas. The elements and flows analyzed were (i) change of land use and cover, (ii) installation of central pivots, (iii) river channel flow, (iv) physical and chemical aspects of canal water fluvial. The river waters were sampled twice (end of rainy and dry seasons) in three points along each channel (Rios Veredãozinho, Pratudinho and Formoso) in the hydrological year 2015-2016. The elements related to land use were obtained by the interpretation of maps generated by a time series classification (1970, 1980, 1990, 2000, 2010 and 2016) satellite images from Landsat (5, 7 and 8) and the other data obtained from public agencies. The results indicate that, in general, the three basins are inserted in the same context of succession of use and land cover, following the trend of what happens around the Chapada do Oeste Baiano. In the 1970s, 1980s and 1990s, the savanna formation burned for the pioneer occupation of livestock and forestry, while agriculture still occupied small stretches of the valleys. From 2000 on, the area of agriculture grows exponentially and gains space over areas of forestry and savanna formations and abandons the valleys. Specifically, RVSVOB and its analogous areas have similar succession of cover and land use up to the creation of the PA in 2000, when, in the PA, the burnings and agriculture start to reduce exponentially. The installation of central pivots and the concession of water grants were also heterogeneous among the three analyzed basins, with a higher concentration in the upper and lower sectoin of the Formoso River basin and in the lower section of the Pratudinho River. The quality and quantity of water in the three sampling points in each basin do not have any significant difference in the measured values, showing, in general, low concentration of suspended load and turbidity and high dissolved oxygen. The evaluation of the effectiveness of RVSVOB allows verifying that, on the one hand, the unit has contributed to the conservation of the Cerrado within its territory - recovering deforested and burned areas and, on the other hand, the quality and quantity of water resources is independent of the existence of RVSVOB, being similar in the nine monitored stretches. This similarity allows affirming that the quality of the water resources is good in all points, however, the lack of flow data prior to the superficial and underground grants does not allow evaluating if there is loss in the amount of water in the channels. This framework shows that, on the one hand, the Refugio de Vida Silvestre Veredas do Oeste Baiano has fulfilled its ecological function, ensuring the quality of natural resources, on the other, the expansion of agribusiness occupies preferably the areas of the highlands and plateaus not pressing the dynamic of enclosed valleys but indirectly. / A proteção dos recursos naturais pela criação de unidades de conservação (UCs) tem sido implementada no Brasil com relativo sucesso, permitindo uma diversidade significativa de enquadramentos de áreas entre proteção integral e uso sustentável. A efetividade dessas UCs é determinada pelos atores sociais envolvidos na unidade e em seu entorno. Só no Cerrado, existem 386 unidades de conservação que recobrem todo o bioma em diferentes contextos sócio-econômico-ambientais. Destacadamente, a porção setentrional desse bioma está sob franca pressão pela intensificação da conversão do Cerrado pelo agronegócio, o que é potencializado desde a criação da região do MATOPIBA. Na Chapada do Oeste Baiano, essa expansão tem sido polarizada, especificamente, pelos municípios de Luiz Eduardo Magalhães e Barreiras, e foi intensificada nos últimos 15 anos com a consolidação dos projetos de irrigação por pivôs centrais. Em 2000, o governo federal criou o Refúgio da Vida Silvestre Veredas do Oeste Baiano (RVSVOB) nessa região para proteger, integralmente, um habitat do pato mergulhão (Mergus octosetaceus). Seus limites geográficos seguem, grosso modo, o traçado do vale encaixado do Rio Pratudinho e do alto vale do Rio Pratudão, incluindo, em seu extremo leste, uma parte de colinas dissecadas. Apesar de ser protegida, a área e sua função ecológica vem sofrendo com os impactos causados pelas pressões antrópicas da ocupação das chapadas (explotação de água para os projetos e instalação pivôs centrais, e.g.) e própria aos vales encaixados (queimadas, pastoreio, erosão acelerada, e.g.). Por esses problemas e pela estrita relação que a UC tem com os recursos hídricos superficiais, a efetividade da RVSVOB pode ser colocada em xeque. Nesse contexto, propõe-se avaliar a efetividade dessa UC por meio da análise e modelagem de sistemas ambientais análogos espaço-temporais. Para tanto, foram escolhidas as bacias hidrográficas adjacentes, a norte, do Rio Veredãozinho, e, a sul, do Rio Formoso, onde foram delimitadas áreas análogas a RVSVOB para análises comparativas dos elementos e fluxos mais importantes na função ecológica da RVSVOB. As unidades de análise adotadas foram: (i) bacia hidrográfica, (ii) trechos de bacia hidrográfica (alta, média e baixa), (iii) RVSVOB e áreas análogas. Os elementos e fluxos analisados foram: (i) mudança do uso e cobertura do solo, (ii) instalação de pivôs centrais, (iii) vazão do canal fluvial, (iv) aspectos físico-químicos da água do canal fluvial. As águas fluviais foram amostradas duas vezes. Os elementos relacionados ao uso do solo foram obtidos pela interpretação de mapas gerados pela classificação de uma série histórica (1970 a 2016) de imagens de satélite LANDSAT (1, 5 e 8) e os demais dados foram obtidos junto a órgãos públicos. Os resultados indicam que, em geral, as três bacias estão inseridas em um mesmo contexto de sucessão de uso e cobertura do solo, seguindo a tendência daquilo que acontece em todo a Chapada do Oeste Baiano. Em 1970 a 1990, predominou a queimada da formação savânica para a ocupação pioneira de pecuária e silvicultura, quando a agricultura ainda ocupava pequenos trechos dos vales. A partir de 2000, a área de agricultura cresce exponencialmente e ganha espaço sobre áreas de silvicultura e de formações savânicas e abandona os vales. Especificamente, a RVSVOB e suas áreas análogas tem sucessão de cobertura e uso do solo semelhantes até a criação da UC em 2000, a partir de quando, na UC, as queimadas e a agricultura passam a reduzir exponencialmente. A instalação de pivôs centrais e outorgas de água também foram heterogêneas entre as três bacias analisadas, tendo maior concentração no alto e médio trecho bacia do Rio Formoso e no baixo trecho do Rio Pratudinho. A qualidade e quantidade de água nos três pontos amostrados em cada bacia não tem nenhuma diferença significativa nos valores mensurados, tendo, em geral, baixa concentração de carga em suspensão e turbidez e elevado oxigênio dissolvido. A avaliação da efetividade da RVSVOB pelo método adotado permite constatar que, por um lado, a unidade tem contribuído para a conservação do Cerrado dentro de seu território – recuperando áreas desmatadas e queimadas – e, por outro lado, a qualidade e quantidade dos recursos hídricos independe da existência da RVSVOB, sendo similar nos nove trechos monitorados. Essa similaridade permite afirmar que a qualidade dos recursos hídricos é boa em todos os pontos, por outro lado, a inexistência de dados de vazão anteriores às captações superficiais e subterrâneas não permite avaliar se há perda na quantidade de água nos canais. Esse quadro permite concluir que, se por um lado, o RVSVOB tem cumprido sua função ecológica, garantindo a qualidade dos recursos naturais, por outro, a expansão do agronegócio ocupa, preferencialmente, as áreas das chapadas e platôs, não pressionando a dinâmica os vales encaixados diretamente, mas sim indiretamente.

A migração coletiva de membros da comunidade portuguesa de Macau para o Brasil, parte da chamada Segunda Diáspora Macaense, é elaborada nesta pesquisa de acordo com as proposições de Sayad sobre a dupla condição de emigrante-imigrante do sujeito migratório. Assim, as condições que engendraram o movimento de saída da China são analisadas de modo a construir escopo interpretativo para a qualificação de tais membros como refugiados e contextualizar sua recepção e integração na sociedade brasileira entre as décadas de 1950 e 1970. Tal trajetória é estudada a partir de depoimentos que partem de elaborações individuais e coletivas sobre a experiência colonial, a assunção identitária e aspectos relativos ao deslocamento, à condição de imigrante e à integração no Brasil. O referencial teórico de análise de tais depoimentos e do contexto sócio político que emergem encontra-se nos Estudos Culturais, mais precisamente em obras da teoria pós-colonial. Apesar de não tratarem especificamente do caso chinês, as semelhanças na atuação da empresa colonialista e seus efeitos possibilitou aproximações. Isso pois os territórios colonizados, em suas experiências originais, são marcados por relações de poder, violências de toda ordem e sínteses multiculturais, de onde emergem sujeitos cindidos e hifenizados. Tal conformação societária, marcada por ambiguidades e distanciamentos, é pensada, então, em sua interface com o controverso momento político de descolonização já em meados do século XX. Particularmente em se tratando da China, o avanço do movimento revolucionário sob a liderança de Mao Tsé Tung marcou uma ruptura com o imperialismo, abrindo margem para a construção de um discurso nacional e de uma identidade chinesa em que as comunidades híbridas, consideradas estrangeiras, não eram contempladas. A ascensão do nacionalismo defensivo teve função precisa de subversão da ordem colonial e, entre outros fatores, implicou direta e indiretamente na exclusão de minorias. Considerada indesejável no cálculo do Estado em formação, a comunidade portuguesa passa a sair da China em processo diaspórico, sob a condição de refugiada. Os macaenses que vivem no Rio de Janeiro constituem parte significativa da Segunda Diáspora Macaense e são considerados aqui em seus discursos enunciativos, suas experiências nos entrelugares e estratégias de sobrevivência, tais como as negociações identitárias e práticas associativistas. / The collective migration of members of the Portuguese community from Macao to Brazil, part of the so-called Second Macanese Diaspora, is elaborated in this research according to Sayad\'s proposals on the migrant-immigrant dual status of migrattion subject. Thus, the conditions that engendered the outgoing movement of China are analyzed in order to construct an interpretive scope for the qualification of such members as refugees and to contextualize their reception and integration in brazilian society between the 1950s and 1970s. Such trajectory is studied from individual and collective experiences, registered in testimonies, about the colonial way of life, identity assumption at this contexto and issues on displacement, immigrant status and non-Brazilian integration. The theoretical framework of analysis of such testimonies and the socio-political context that they emerge is found in Cultural Studies, most precisely in works developed on postcolonial theory. Although they did not deal specifically with the Chinese case, the similarities on how companies updated the colonialist enterprise and its effects provided approximations. That happens because colonized territories, in their original experiences, are marked by relations of power, violence of all orders and multicultural syntheses, from which split and hyphenated subjects emerge. This societal conformation, marked by ambiguities and distances, is then thought through an interface with the controversial political moment of decolonization occured in the middle of the twentieth century. Particularly regarding to China, the advance of the revolutionary movement under Mao Tse Tung\'s leadership marked a break with imperialism, opening the way for a construction of a national discourse and a Chinese identity in which, as foreign were not contemplated. The rise of defensive nationalism had a precise function of subversion of the colonial order and, among other factors, directly and indirectly implied the exclusion of minorities. Considered undesirable in the calculation of the State in formation, a Portuguese community starts to leave China in diasporic process, under the condition of refugee. The Macanese who live in Rio de Janeiro constitute a significant part of the Second Macanese Diaspora and they are considered here in their enunciative speeches, their experiences in the interludes and strategies of survival, such as the identity negotiations and associative practices.

The seasonal distribution of the Florida manatee (Trichechus manatus latirostris) is influenced predominantly by feeding locations in the summer and proximity to warm-water refuges during colder months. Due to their limited ability to tolerate cold water, when water temperatures drop below 20°C manatees congregate around natural and artificial warm-water refuges, such as warm-water springs or power plant outfalls. Distribution may further be influenced by the tidal cycle through its impact on manatee movement and foraging. Although the importance of tide on manatee distribution and habitat selection has been acknowledged, it has yet to be studied quantitatively in respect to the manatee population in southeast Florida. The purpose of this study was to examine the effect of the tidal cycle on manatee occurrence at the Florida Power & Light (FPL) Port Everglades Power Plant. Walking surveys were conducted in Port Everglades during manatee season, November 15 – March 31, between 2004 and 2008. During the surveys, the number of manatees in four established locations was noted and the animals categorized based on size as either calf, juvenile, or adult. Water temperature data were also collected at four permanent sample locations. Because many surveys yielded zero manatees observed, data were analyzed using the zero-inflated negative binomial model. Although the manatees at the Port Everglades Power Plant must forage away from the warm-water refuge, my findings show no correlation between tidal state and total manatee occurrence at the FPL Port Everglades Power Plant. The results do, however, suggest that the probability of observing a cow/calf pair is greater during high tide when compared to low and mid-tides (P < 0.05). Total manatee occurrence and the presence of cow/calf pairs were both significantly correlated with water temperature (P < 0.05).

The Florida manatee (Trichechus manatus latirostris), a subspecies of the West Indian manatee, is one of the most endangered marine mammals in United States waters. The Florida manatee is the only manatee that ranges into subtropical and temperate regions. During the winter months manatees adopt a “refuging strategy” where they aggregate at warm-water sources immediately following decreases in the ambient water temperature to below 20° C (68° F) in order to avoid cold stress syndrome (CSS). During the winter manatees aggregate in warm water refuges, including natural warm water springs and the effluent discharges of power plants. The purpose of this study was to determine the number of manatees that aggregate and utilize the waters of the Florida Power and Light (FPL) Plant in Port Everglades (PPE), Florida, its effluent canal, and the surrounding Intracoastal Waterway during the winter months. This study documents the importance of Port Everglades as a wintering refuge for the Florida manatee. This study analyzed the inverse relationship between the number of manatees present at a warm water effluent and water temperature. In this study data were collected over five manatee winter seasons (between 15 November and 31 March) from 1999-2004, from both boat-based and land-based surveys monitoring the presence of manatees in the effluent canal from the FPL electricity generating facility in Port Everglades, FL and the Intracoastal Waterway. Findings indicated that there was an inverse relationship between the number of manatees present and water temperature, where more manatees were present in cooler months, and fewer in warmer months. This study also analyzed the parameters of Catch per Unit Effort (CPUE) as well as heating degree-days and their effect on and relationship to the number of manatees present. The higher the heating degree-days number, the more severe, or cold, winter this indicates. The year with the highest heating degree-days, 24.98, was the 2002-2003 season, which was also the season with the highest number of manatees observed, 393, and the highest CPUE, 10.62 manatees/day.

This study compared two remote sensing water indices: the Normalized Difference Water Index (NDWI) and the Modified NDWI (MNDWI). Both indices were calculated using publically-available data from the Landsat 8 Operational Land Imager (OLI). The research goal was to determine whether the indices are effective in locating open water and measuring surface soil moisture. To demonstrate the application of water indices, analysis was conducted for freshwater wetlands in the Tualatin River Basin in northwestern Oregon to estimate hydrologic connectivity and hydrological permanence between these wetlands and nearby water bodies. Remote sensing techniques have been used to study wetlands in recent decades; however, scientific studies have rarely addressed hydrologic connectivity and hydrologic permanence, in spite of the documented importance of these properties. Research steps were designed to be straightforward for easy repeatability: 1) locate sample sites, 2) predict wetness with water indices, 3) estimate wetness with soil samples from the field, 4) validate the index predictions against the soil samples from the field, and 5) in the demonstration step, estimate hydrologic connectivity and hydrological permanence. Results indicate that both indices predicted the presence of large, open water features with clarity; that dry conditions were predicted by MNDWI with more subtle differentiation; and that NDWI results seem more sensitive to sites with vegetation. Use of this low-cost method to discover patterns of surface moisture in the landscape could directly improve the ability to manage wetland environments.

Conflicts between local people and protected areas can undermine conservation goals. This study explores perceptions towards Vieques National Wildlife Refuge (VNWR), a complex former military site containing a combination of high ecological value along with an array of unexploded ordnances. The purpose of this research is to evaluate how residents perceive VNWR and elucidate conflicts associated with former and current uses of the wildlife refuge. Here, I interviewed 235 residents of Vieques Island, Puerto Rico using semi-structured surveys and 33 key informants representing various stakeholder groups to assess attitudes toward VNWR. A combination of factors influencing attitudes about VNWR included socio-economic status and misconceptions about management. Overall, residents did not express strong attitudes. However, older individuals and those living longer on Vieques generally had poorer attitudes than others. Among the most common reasons for expressing discontent were the restrictive regulations regarding access to VNWR and the limitations on resource extraction.
