    Description: With increasing pressure on the oceans from environmental change, there has been a global call for improved protection of marine ecosystems through the implementation of marine protected areas (MPAs). Here, we used species distribution modelling (SDM) of tracking data from 14 seabird species to identify key marine areas in the southwest Atlantic Ocean, valuing areas based on seabird species occurrence, seasonality and extinction risk. We also compared overlaps between the outputs generated by the SDM and layers representing important human threats (fishing intensity, ship density, plastic and oil pollution, ocean acidification), and calculated loss in conservation value using fishing and ship density as cost layers. The key marine areas were located on the southern Patagonian Shelf, overlapping extensively with areas of high fishing activity, and did not change seasonally, while seasonal areas were located off south and southeast Brazil and overlapped with areas of high plastic pollution and ocean acidification. Non-seasonal key areas were located off northeast Brazil on an area of high biodiversity, and with relatively low human impacts. We found support for the use of seasonal areas depending on the seabird assemblage used, because there was a loss in conservation value for the seasonal compared to the non-seasonal approach when using 'cost' layers. Our approach, accounting for seasonal changes in seabird assemblages and their risk of extinction, identified additional candidate areas for incorporation in the network of pelagic MPAs.

    Description: Wie werden aus Bürgern einer Reichsstadt, Untertanen eines geistlichen Fürsten und Vasallen des Kaisers Untertanen des französischen Königs, "sujets du roi"? Dieser Frage wird anhand der Ereignisse in Metz, Toul und Verdun nach der französischen Besetzung im Jahr 1552 nachgegangen. Wie hat sich der Herrschaftswechsel konkret vollzogen? Wodurch wurde das "Französisch-Werden" unterstützt oder behindert? Die Untersuchung betrifft zentrale Themen der Frühneuzeitforschung wie die Kommunikation zwischen Herrscher, Amtsträgern und Untertanen, Fragen der Souveränität und Rechtmäßigkeit, Aspekte der Verrechtlichung und Gerichtsnutzung, aber auch die Frage nach dem Ende der großen lothringischen Hexenverfolgungen.

    Description: Spatial variation on fish assemblages structure of the upper Paraná River floodplain, Brazil. Although the upper Paraná River floodplain is subjected to impacts produced by hydroelectric plants upstream, fish assemblages studies acknowledge its importance in the maintenance of regional biodiversity. Fish assemblages of four categories of biotopes belonging to three subsystems were analyzed. The aim was analyse the spatial variation in the structure and to identify processes responsable to species composition and abundance. Quarterly samples were carried out with gill nets in 19 sites during the year 2000. The sites comprised rivers, channels, connected and disconnected lagoons in the subsystem Paraná and two tributaries, the Baía and Ivinheima Rivers. Connected lagoons showed greater species richness and similar species composition. There were not detected significant differences in diversity and in eveness among categories of biotopes and subsystems. Dominance pattern is achieved by species whose life strategies allow to take advantages of the intensity, duration and frequency changes of the flood pulses. Biotic (predation) and abiotic (local processes) factors explained satisfactorily the assemblages structure.
    Description: Variação espacial na estrutura das assembléias de peixes da planície de inundação do alto rio Paraná, Brasil. Apesar de sujeita aos impactos gerados pelas hidrelétricas a montante, estudos ictiofaunísticos têm reconhecido a importância da planície de inundação do alto rio Paraná na manutenção da biodiversidade regional. Assembléias de peixes de quatro categorias de biótopos, pertencentes a três Sub-sistemas, foram estudadas com o objetivo de caracterizar a variação espacial na estrutura e identificar os processos responsáveis pela composição e abundância das espécies. Durante o ano de 2000, amostragens trimestrais com redes de espera foram realizadas em 19 estações de coleta, localizadas em rios, canais, lagoas abertas e fechadas do sub-sistema Paraná e em dois tributários, Baía e Ivinheima. As lagoas abertas constituíram-se no biótopo com a maior riqueza de espécies e composição específica similar. Entretanto, diferenças significativas na diversidade e eqüitabilidade não foram detectadas entre categorias de biótopos e sub-sistemas. O padrão de dominância é exercido por espécies que, em função de suas estratégias de vida, têm se beneficiado das alterações na intensidade, duração e freqüência dos pulsos de inundação. Fatores bióticos (predação) e abióticos (processos locais) foram considerados explanatórios para a estrutura das assembléias.

    Description: This study tested experimentally the hypothesis that traíra Hoplias aff. malabaricus is a keystone predator in isolated lagoons of the upper Paraná River floodplain. The experiment was conducted from April to October 2002, through an initial manipulation of traíra density (levels of treatment: addition, removal and reference). Treatment effects were evaluated on descriptors of fish assemblage structure (species richness, abundance, equitability and biomass), through repeated measures analysis of variance, in two habitat categories (open and macrophyte-dominated areas). In spite of being recorded in all assemblages and depended on habitat category, reductions in species richness were significantly more pronounced in lagoons where H. aff. malabaricus was removed. In these lagoons, the number of individuals was also significantly lower than in those where the piscivore was added or maintained in natural densities. Equitability showed opposite tendencies. Analysis of relative abundance by size-classes revealed a sharp reduction in the number of small-sized individuals (〈 3cm), contributing to the absence of pronounced alterations in biomass. These evidences supported our hypothesis and demonstrated that the understanding of mechanisms by which predators affect the persistence of prey species constitutes a challenge for future researches, especially in tropical ecosystems, in which phytoplankton changes in Paraná River were verified, in function of the formation of Porto Primavera Reservoir and the climatic alterations that occurred during the period studied (1993-1994 and 2000-2005), especially those related to El Niño and La Niña phenomena. In the second chapter entitled "Interannual variation of phytoplankton in a river-flooding lake system (Upper Paraná River, Brazil)", we verified that the alterations of phytoplankton structure in Patos Lagoon and Ivinhema and Paraná rivers were associated to the fluctuations of hydrosedimentological regime of Ivinhema and Paraná rivers, probably, influenced by the phases La Niña (2000-2001) and El Niño (2003-2004) Southern Oscillation cycle (ENSO).
    Description: O presente estudo testou experimentalmente se a traíra Hoplias aff. malabaricus pode ser considerada uma espécie-chave nas lagoas isoladas na planície de inundação do alto rio Paraná, no período de abril a outubro de 2002, através da manipulação inicial em sua densidade (níveis do tratamento: adição, remoção e referência). Os efeitos desse tratamento foram avaliados nos descritores da estrutura das assembléias (riqueza de espécies, abundância, eqüidade e biomassa), através de análises de variância com medidas repetidas em duas categorias de hábitat (área aberta e coberta por macrófitas). Apesar de registradas em todas as assembléias e dependerem da categoria de hábitat, as reduções na riqueza de espécies foram significativamente mais pronunciadas em lagoas onde H. aff. malabaricus foi excluída. Nessas lagoas, o número de indivíduos também foi significativamente menor em relação àquelas nas quais o piscívoro foi adicionado ou mantido em densidade natural, enquanto para a eqüidade as tendências foram opostas.

    Description: As part of the activities of the Doctorate Program in Ecology of Continental Aquatic Environments at the Maringa University State, a research project was conducted on the perception of quality of life by a segment of the residents of the municipality Porto Rico, Parana State, Brazil. The study investigated how environmental processes are related with the health conditions of the Porto Rico population and with their evaluations of their own quality of life; based on that knowledge, it would be possible to devise proposals to minimize such conditions. The study was conducted at the Flamingo, Por do Sol and Casa Feliz housing complexes, which are located in the urban area of town, during the months of June 2005 and January 2006. The sample consisted of 63 residents of all three complexes. Data were obtained through home surveys, using two forms devised by the World Health Organization's Group for Quality of Life (OMS, 1998): the Abbreviated Instrument for Quality of Life Assessment (WHOQOL-bref) and the Respondent Data Sheet, with additional data on the family members of that household. The data were processed using Statistical Analysis Software (SAS) and Statistical Package for the Social Sciences (SPSS) software, and the CHAID algorithm. Initially, the study evaluated the socioeconomic and work conditions of 63 families living in the aforementioned housing complexes, with a total of 224 people. Next, self-reported morbidity was compared between both groups of interviewees, and the CHAID technique was applied to explain the trends in the variables that explained the evaluation of the quality of life of that population, as analyzed by WHOQOL-bref. The results indicated that the social conditions of these families were influenced by their low levels of education, allied with the lack of work options, thus compromising family income. Residents of group B mentioned better health and income conditions. The findings of self-reported morbidity followed the national trend of acute infectious diseases caused by inadequate environmental conditions and of chronic illnesses, in groups of middle-aged and elderly groups, as results of chosen lifestyles and the social conditions of the residents. Most interviewees expressed satisfaction regarding their quality of life. The variables that generated the most dissatisfaction were related to pain and available transportation. The use of CHAID made possible the mapping of variables that interfered in the evaluations of each of the domains that make up the concept of 'quality of life', and its use is recommended in similar studies. It can be affirmed that a good quality of life is reflected, most of all, in individual quality of health, which confirms that quality of life depends on conditions of health and surroundings.
    Description: Como parte das atividades do Curso de Doutorado em Ecologia de Ambientes Aquáticos Continentais da Universidade Estadual de Maringá realizou-se um projeto de pesquisa sobre a percepção da qualidade de vida de um segmento de moradores do município de Porto Rico, Estado do Paraná, Brasil. A pesquisa investigou como os processos ambientais se relacionam com as condições de saúde da população de Porto Rico e com as avaliações que a mesma faz sobre sua qualidade de vida para, com base nestes conhecimentos, elaborar propostas que minimizem tais condições. 0 estudo foi realizado nos conjuntos habitacionais, Flamingo, Por do Sol e Casa Feliz, situados no núcleo urbano do município, nos meses de julho/2005 e janeiro/2006. A amostra foi constituída por 63 moradores dos três conjuntos. As informações foram obtidas através de inquérito domiciliar, utilizando-se dois formulários elaborados pelo Grupo de Qualidade de Vida da Organização Mundial de Saúde (OMS, 1998), o Instrumento de Avaliação de Qualidade de Vida abreviado (WHOQOL-bref) e a Ficha de Informações sobre o Respondente, acrescida de alguns dados sobre os familiares daquela residência. Os dados foram processados nos programas Statistical Analysis Software (SAS), Statistical Package for the Social Sciences (SPSS) e no algoritmo CHAID. Inicialmente foram avaliadas as condições sócioeconômicas e laborais de 63 famílias, residentes nos respectivos conjuntos habitacionais, abrangendo 224 pessoas. Na seqüência, foi comparada a morbidade referida entre dois grupos de entrevistados e aplicada a técnica de "Regressão por Árvore" para explicar as tendências das variáveis que influenciaram a avaliação da qualidade de vida daquela população, analisada pelo WHOQOL-bref. Os resultados indicaram que as condições de vida dessas familias foram influenciadas pelo baixo nível de instrução aliado a falta de opções para o trabalho, comprometendo assim a renda familiar. 0 Grupo B referiu melhores condições de saúde e renda do que o Grupo A. Os achados da morbidade referida acompanham a tendência nacional de doenças infecciosas agudas causadas por condições ambientais inadequadas e de doenças crônicas, em grupos de meia-idade e terceira idade, decorrentes dos estilos de vida adotados e conseqüentes às condições de vida dos moradores. A maioria dos entrevistados referiu satisfação em relação à sua qualidade de vida. As variáveis que geraram maior insatisfação foram relacionadas à dor e aos meios de transporte disponíveis. 0 emprego da técnica de Regressão por Árvore permitiu o mapeamento das variáveis que interferiram nas avaliações de cada um dos domínios que compõem o conceito de qualidade de vida, sendo recomendada sua adoção em estudos semelhantes. Pode-se afirmar que uma boa qualidade de vida é refletida, sobretudo, pela qualidade da saúde individual, o que vem a comprovar que a qualidade de vida depende das condições de saúde e do seu entorno.
