This thesis describes the motif connecting two sides of a few selected aspects are essential to the concept of integral theme. The theoretical part is devoted to symbolic and philosophical significance of the theme of the bridge, which is linked to a gradual work. It focuses on the genesis of the architecture of the bridge together with social and cultural background. Subsequently imaging theme deals with the bridge in the history of visual culture. Practical implemented using spatial concepts of subjective motive in terms of symbolism encoded in a simplified bridge construction, located in the illusionary space of emptiness, allowing mutual connection.

Um contexto marcado por vários processos de exclusão e por uma urbanização informal. O propósito é capturar como a cidade é inventada a partir de suas margens, pelas múltiplas situações cotidianas vivenciadas pelos seus habitantes, através da produção dos espaços de interação, formação das redes de sociabilidade, trocas e reciprocidade. Este estudo tem como categoria central de análise os modos de habitar, articulando os conceitos de memória coletiva, entrelugares, fronteira, território, territorialidade e contextos específicos. A proposta é submeter à perspectiva globalizante e normativa de cidade a experiência particularizada e contextualizada dos grupos que inventam e vivem a cidade, para pensá-la em termos históricos, processuais e relacionais, e de uma descolonização epistemológica na produção do conhecimento sobre os modos habitar os territórios periféricos pensando o trabalho antropológico junto às políticas públicas. / This study aims to comprehend the ways of living the city since the daily life of the groups that live in the urban shores and at the margins of the State instituitions. These groups are not found in the representations and in the officials narratives about the city. It was realized an ethnographic study in an unofficial village located in the Três Vendas neighborhood, city of Pelotas, state of Rio Grande do Sul, Brazil. A context marked by many processes of exclusion and by an informal urbanization. The objective of this study is to capture how the city is invented since the shores, by the multiples daily situations lived by the its inhabitants. This study uses as a central category of analysis the ways of living, articulating the concepts of collective memory, among-places, frontier, territory, territoriality and specified contexts. The purpose of this study is to submit to the globalizing and normative perspective of city the particularized and contextualized experience of the groups that invent and live the city with the aim of thinking about the city in historical, processual and relational terms. This study is a epistemologic decolonization in the production of knowledge about the ways of living the peripheric territories in the anthropologic work together with the public politics.

This thesis provides new insight concerning drivers behind differences in arthropod diversity and abundance in Baltic shore ecosystems and how the arthropod communities might be affected when the conditions in the Baltic Sea are altered due to climate change.  The focus has been on climate related changes that are unique for coastal ecosystems, especially sea level rise and changes in the inflow of marine nutrients. As sea levels rise, features in coastal landscapes will be altered, islands and habitats will be flooded and diminished, and structural connectivity within the island landscape will therefore change. This thesis shows that arthropod diversity within the two arthropod groups, spiders and beetles, increases with island size but also that diversity is positively influenced by a high number of islands in the surroundings. A changed distribution and occurrence of marine species, due to climate change or eutrophication, can also affect terrestrial organisms on the shore.  In the Baltic Sea the new conditions following climate change will decrease the prevalence of bladder-wrack and benefit filamentous algae. Algal deposits on shores reflect the marine species composition and a decreased prevalence of bladder-wrack in the Baltic Sea will also be visible on the shores.  This thesis shows that a lower proportion of bladder-wrack in the algal deposits will decrease the diversity and abundance of arthropods in these deposits. Changes in the marine environment may also affect the inflow of insects with aquatic life stages and terrestrial adult stages.  On Baltic shores, prey species with aquatic life stages, especially chironomids, constitute a large proportion of the diet of the terrestrial predatory group, wolf spiders. In freshwater system, the inflow of chironomids is known to decrease with elevated water temperatures if this is true in the Baltic Sea prey availability of wolf spiders would decrease.  This thesis supports the importance of chironomids as a prey for coastal wolf spiders, but also shows that the diet varies over season with dominance of terrestrial prey in early summer shifting to a dominance of marine prey in late summer and autumn. This seasonal variation is primarily due to a gradual increase in the consumption of chironomids over season. Climate change has the potential to alter the biogeographical conditions in coastal landscapes as well as the density and quality of marine nutrient inflow. Sea level rise will diminish and flood islands and this thesis shows that a moderate sea level rise of 0.5 meters would make the total number of islands in the outer part of Stockholm archipelago decrease with about 25 %. Sea level rise could thus have consequences for arthropod diversity in Baltic shore meadows in the near future. The combined effects of sea level rise and changed prevalence of marine species in the Baltic Sea will affect the abundance and diversity of arthropods substantially. The abundance and diversity of spiders and beetles will decrease on shores that today have a high occurrence of bladder-wrack and prey availability for coastal predators might decrease due to a decreased inflow of chironomids. Changes in the arthropod communities could have consequences also further up in the food chain, such as for shore birds feeding on these arthropods. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Manuscript.

La distribution d'espèces benthiques intertidales est contrainte par l'océanographie côtière. On connaît moins les effets sur l'écologie des prédateurs. Les côtes sud de l'Afrique sont caractérisées par des contrastes de production primaire et d'assemblages intertidaux dus aux deux courants majeurs qui les longent. Le prédateur apical de ces côtes est un oiseau limicole endémique, l'huîtrier noir africain (Haematopus moquini), qui présente un polymorphisme favorable à la spécialisation alimentaire. Ces travaux ont étudié l'effet des variations spatiales de structure de communautés benthiques sur l'écologie alimentaire de l'huîtrier à l'aide des isotopes stables. Les oiseaux répondent aux fluctuations qualitative et quantitative des communautés de proies à plusieurs échelles. A large échelle ils montrent de forts contrastes entre les côtes ouest et sud-ouest où le régime alimentaire est dominé par les moules, notamment l'espèce invasive Mytilus galloprovincialis et le sud-est où un mélange de moules et patelles est consommé. Localement les individus montrent des différences faibles d'alimentation liées à l'abondance relative des moules et patelles. Cela s'explique par le caractère généraliste de l'espèce et le relâchement de compétition intra-spécifique pour les ressources. La transition alimentaire d'H. moquini vers une consommation quasi-exclusive à l'ouest d'une moule introduite et la multitude de comportements alimentaires ailleurs indiquent un fort potentiel d'adaptation aux modifications de son habitat d'alimentation. En revanche la dégradation des plages par l'Homme augmente la compétition pour l'espace et affecterait aujourd'hui le succès reproducteur de l'espèce. / The distribution of intertidal benthic species is constrained by coastal oceanography. Less is known about the effects on the ecology of predators. Along the southern coasts of Africa the two main currents constraint both the patterns of primary production and the structure of benthic communities. The top predator on these coasts is an endemic shorebird, the African Black Oystercatcher (Haematopus moquini), which exhibits a polymorphism favourable for food specialization. This study investigates the effect of spatial variations in benthic community structure on the feeding ecology of oystercatchers using stable isotopes. Birds respond to changes in quality and quantity of prey at multiple scales. At large scale they show strong contrasts between west and southwest coasts where the diet is dominated by mussels, including the invasive species Mytilus galloprovincialis, and south-east shores where a mixture of mussels and limpets is consumed. Locally individuals show weak dietary differences related to relative abundances of mussels and limpets. This reflects the generalist foraging behaviour of the species and the release of intra-specific competition for resources. The dietary shift of H. moquini on the west coast toward the invasive mussel and the multiplicity of foraging behaviours elsewhere reveal strong capacities to face changes in its foraging habitat. On the other hand the degradation of beaches by humans increases the competition for space and today affects the reproductive success of the species

2009/2010 infördes i Miljöbalken och Plan- och Bygglagen ett nytt begrepp, landsbygdsutveckling i strandnära lägen (LIS). Lagändringen genomfördes med motiveringen att områden med låg exploateringsgrad samt god tillgång till stränder skulle få en möjlighet till lättnader i strandskyddet, detta för att kunna erbjuda attraktiva lägen för boende och verksamhet inom kommunen. Sedan denna ändring infördes har kommunerna huvudansvaret för att pröva dispenser för strandskydd inom kommunen, Länsstyrelsen har huvudsakligen en granskande roll. När lagändringen 2009/2010 kom infördes det i Plan- och Bygglagen en möjlighet för kommunerna att sedan 1 februari 2010 peka ut LIS-områden inom kommunen i sin översiktsplan, tematiskt tillägg till översiktsplanen eller i en fördjupad översiktsplan. Syftet med denna studie är att jämföra och kartlägga hur 44 kommuner runtom i landet använder sig av LIS. Studien syftar även till att kartlägga hur olika Länsstyrelser i olika län runtom i landet arbetar tillsammans med kommunerna i frågan om LIS. Studiens första del är kvantitativ för att sammanställa den statistik som ligger till grund för studiens resultat. Studien innehåller även en kvalitativ del som syftar till att analysera den statistik som framställts inom studien. Studien mynnar ut i slutsatsen att kommunerna och Länsstyrelsen har olika syn på LIS i helhet, vilket syns genom de synpunkter som Länsstyrelsen lämnar till kommunen via sitt granskningsyttrande. Ett mönster för vilka synpunkter som är vanligast att Länsstyrelsen lämnar har uppmärksammats inom studien. De vanligaste synpunkterna från Länsstyrelsen är att kommunerna inte tillgodosett syftet med LIS, syftet med strandskyddet samt ett eller flera riksintressen som påverkar tillämpningen av LIS. Studien visar att kommunerna följer den lagstiftning som reglerar var LIS-områden får pekas ut. Studiens fördjupande del visar att kommuner med olika politisk styrning arbetar med LIS på varierande sätt. De huvudsakliga skillnaderna i hantering av LIS-områden beroende av politisk styrning är antalet områden som pekas ut. Den politiska styrningen inom en kommun har större inverkan på utpekande av antalet LIS-områden än kommunens geografiska läge i Sverige, enligt den fördjupande delen i studiens resultat. / 2009/2010 a new concept was brought into Environmental code and Planning and Building Act, which was countryside development in areas close to shores (LIS). This amendment was motivated by that areas which have a low degree of exploited land area and high access to seaside areas would get an opportunity to reliefs in coastal protection regulations, in order to be able to offer attractive areas for living and establishing different activities within the municipality. Since the amendment came into force the main responsibility for approval of exceptions from costal protection regulations is on the county. The county administrative board main responsibility is to keep an eye on the granted approvals of the municipalities. The amendments in the Planning and Building Act resulted in the possibility for the municipalities to present areas in with a relief in coastal protection regulations, as a part of the comprehensive plan, an addition to the comprehensive plan or an extensive version for a part of the comprehensive plan. The purpose of this study is to investigate and compare how the legislation about LIS is applied, by studying 44 municipalities including the documents of comments from the county administrative board. The first part of the study is the quantitative part which contains collecting and compile information and statistics in which the study will be founded. The study also contains a qualitative part of analyzing the results obtained in the quantitative part. Overall the study shows that there is a disagreement between the municipalities and the county administrative board regarding costal protection regulation. The conclusion is based on the results from the study presenting the comments from the county administrative board to the municipalities during the final examine before the comprehensive plan is adopted by the municipal council. The results in the study show a pattern in the most frequent comments from the county administrative board compiled. The most common comment from the county administrative board is that the municipality has not fulfilled the purpose of the legislation about LIS. Furthermore, the municipality has not considered national interests in the municipal areas meant for LIS. The study shows that different political ideology has an influence on the execution of the legislation about LIS in municipalities. The results in the study show that the political ideology has an impact on the numbers of areas which the municipalities present as LIS. As a matter of fact, the impact of political ideology is greater than the impact of geographical similarities between two municipalities, according to the results in the study.

Marine communities are affected by oceanographic processes, which influence ecological interactions, such as recruitment rates, that are essential regulators of community dynamics. These relationships are not constant; they change in space and time or among taxa. We defend the thesis that oceanographic processes of climatic origin influencing larval abundance at the study region, regulate and establish the trends in settlement and recruitment of invertebrates (cirripeds and bivalves) at rocky shore intertidal. We first investigated the recruitment at different temporal scales and its relationships with physical forcings, chlorophyll-a concentration and sea surface temperature. Second, we focused on the spatial synchrony and contrasts of recruitment, and interspecific trends. Third, we described and evaluated the co-variation between cold fronts and the larval abundance and settlement. We concluded that there is a high degree of correlation between recruitment/settlement and the variation of the wind field, which set temporal trends. Cold fronts are important regulators of settlement, but higher recruitment was associated to NE-E winds. Barnacle recruitment is more susceptible to the environmental variations compared to bivalves. Regional recruitment is not spatially synchronic with differences in the scale of 100 km. This study highlights the importance of oceanic-climatic phenomena as predictors of spatio-temporal trends of recruitment showing that climatic fluctuations might have contrasting effects on rocky shore communities. / As comunidades marinhas são afetadas por processos oceanográficos que influenciam as interações ecológicas, como as taxas de recrutamento, reguladores essenciais da dinâmica dessas comunidades. Essas relações não são constantes, elas mudam no espaço e no tempo, ou entre taxa. Aqui nós defendemos a tese que processos oceanográficos de origem climática, por influenciarem a abundância larval região de estudo, regulam e estabelecem tendências do assentamento e recrutamento de invertebrados (cirripedes e bivalves) do entremarés de costas rochosas. Primeiramente, nós investigamos o recrutamento em diferentes escalas de tempo e sua relação com forçantes físicas, concentração de clorofila-a e temperatura da superfície do mar. Em um segundo momento, nós focamos na sincronia e nos contrastes espaciais do recrutamento, e as tendências inter-específicas. Por fim, descrevemos e avaliamos a co-variância entre frentes frias, abundância larval e assentamento. Concluímos que há um alto grau de correlação entre recrutamento/ assentamento e a variação do campo de ventos, o qual estabelece as tendências temporais. As frentes frias são reguladores importantes do assentamento, mas o recrutamento mais alto está associado a ventos de NE-E. O recrutamento de cirripedes é mais susceptível às variações ambientais se comparado aos bivalves. O recrutamento regional não é sincrônico no espaço, com diferenças na escala de 100km. Este estudo destaca a importância dos fenômenos oceano-climáticos na previsão de tendências espaço-temporais do recrutamento, mostrando que flutuações climáticas podem ter efeitos contrastantes nas comunidades de costas rochosas.

Este trabalho analisa as Áreas de Preservação Permanente (APPs) contíguas aos corpos d\'água urbanos como um recurso para a configuração do sistema de espaços livres das cidades brasileiras. Muito embora sua função específica - conforme estabelecido pelo Código Florestal Brasileiro (Lei n° 12.651/2012) - seja proteger recursos hídricos e ecossistemas associados, as APP se consolida, neste início de século XXI, como um importante parâmetro para o planejamento e gestão de orlas fluviais situadas em áreas urbanas, sendo incorporada as políticas de ordenamento do solo e provisão de espaços livres públicos, e estruturando uma série de ações urbanísticas e paisagísticas contemporâneas que se multiplicam pelo país e criam novas formas de aproximação entre as cidades e os seus rios. A espeito dos avanços proporcionados pela lei na proteção dos recursos ambientais existentes nas cidades, a problemática socioambiental e urbanística vinculada a essas áreas exige abordagens menos conservacionistas e mais abrangentes no sentido de considerar as múltiplas funções desempenhadas por essas áreas na complexa e diversa realidade urbana. Entre os diversos caminhos possíveis para esta discussão, o presente trabalho propõe uma abordagem morfológica para avaliar as relações entre as orlas fluviais e as áreas urbanas, e identificar as impressões que a lei produz sobre os espaços livres e suas formas de uso e apropriação. A primeira parte do trabalho se dedica a conceituar a orla fluvial como parte de um sistema urbano e a traçar um panorama sobre os conceitos de planejamento e projetos adotados para o tratamento dessas áreas, destacando um conjunto de ações contemporâneas realizadas no Brasil e no mundo. Na segunda parte, o trabalho avalia a influência da lei sobre a conformação do sistema de espaços livres em diferentes cidades brasileiras, por meio da análise de padrões morfológicos que permitem identificar limitações, conflitos e pontos der aderência da lei ao contexto urbano. Na conclusão, são apresentadas as considerações finais e um panorama sobre os padrões analisados no trabalho, os quais podem servir de referencial metodológico para a formulação de políticas públicas e ações urbanísticas adequadas para uma melhor integração das orlas fluviais às cidades. / This work analyses the Permanet Preservation Areas (APP) adjacent to urban waterbodies as a resort to the conformation of Brazilian cities open spaces system. Although its specific function - as established by the Brazilian Forest Code (Law n. 12.651/2012) - is to protect water resources and associated ecosystems, the APP consolidates itself, in this beginning of the XXI century, as an important parameter to the planning and management of river shores located in urban areas, being incorporated to land management and provision of public open spaces policies, structuring a series of urban and landscape contemporary actions that multiplies throughout the country and create new forms of interface between the cities and its rivers. Despite the advances brought by the law to the protection of cities existing environmental resources, the socio-environmental and urban problems associated to these areas demand less conservationist and more broadening approaches in a way that considers the multiple functions played by these areas in the complex and diverse urban reality. Among the numerous possible ways to this discussion, the present work puts forward a morphological approach to evaluate the relations between river shores and urban areas and identify the fingerprints that the law produces onto the open spaces systems and its forms of use and appropriation. The first part of this work is dedicated to conceptualizing the fluvial shores as a part of an urban system andoutlining an overview on the concepts of planning and design adopted in the treatment of these areas, highlighting a set of ontemporary actions undertaken in Brazil and in the world. In its second part, the work evaluates the influence of the law in the conformation of open spaces system in different Brazilian cities through the analysis of morphological patterns that enables the identification of limitations, conflicts and points of agreement between the law and the urban context. At the conclusion, the final considerations are presented along with a summary table of the analysis criteria adopted in the work, which can serve as methodological benchmarks to the formulation of adequate urban policies and urban actions to a better integration of river shores to the cities.

La mer a d’abord été un espace géographique bien réel dans la vie de Chateaubriand, l’immense champ libre accordé à son enfance. En ouvrant le monde grand large devant son regard, la mer autorisait une manière singulière d’en prendre possession. L’auteur des Mémoires d’outre-tombe se revendique navigateur, découvreur, voyageur. Il utilise spontanément le vocabulaire des matelots. Pourtant, il n’a vécu au bord de la mer que sept années pendant l’enfance, n’a effectué ensuite que des escales brèves, sous des cieux étrangers. Il se réfère malgré tout à la mer à chaque instant, la réinstalle sans cesse dans un texte avec lequel d’innombrables correspondances finissent par s’établir. L’écriture elle-même épouse le rythme de la mer, ses harmonies variables. On croit toujours entendre au loin comme le roulement des vagues, comme le bruit du ressac. Tout se passe comme si la sensibilité et l’imagination de l’écrivain, demeurées marquées par une sorte de paysage originel, lisaient le monde à travers un filtre, et lui conféraient instinctivement les teintes, les arrière-plans propres aux rivages quittés. Chateaubriand se demandait avec anxiété si les Mémoires resteraient lisibles à la postérité. Mais l’écriture et la mer renvoient à une même conception de l’éternité : elles écrivent en lettres temporaires des chants qui durent toujours / The sea was first a real geographical space in Chateaubriand’s life, the boundless playing field of his childhood. By unfurling the world at large under his gaze, the sea provided him with a singular mode of appropriating it. The author of the Mémoires d’outre-tombe claimed for himself the status of seaman, discoverer, and traveller. The maritime lexicon comes to him spontaneously. While he only spent seven years of his childhood by the sea, then subsequently stopped but briefly in foreign port of calls, he keeps on referring time and again to the sea, and incessantly reinstates it in his texts, thus elaborating a rich netwwork of echoes. His very style evokes the rhythm of the sea and its ever-changing harmonics. The reader always seems to hear resounding waves and backwash in the distance. It is as if the writer’s sensibility and imagination, bearing the stamp of a foundational landscape, had him perceive the world through the shades and against the backdrops peculiar to the shores he left. Chateaubriand anxiously wondered whether the Mémoires would remain readable to his posterity. But writing and the sea conjure up the same idea of eternity : they write in labile script everlasting songs
