13. Estratégias de forrageamento e evitação de predadores em Charadriidae e Scolopacidae na Baía de Todos os Santos, Bahia, Brasil
Shorebirds (Charadriidae and Scolopacidae) are a notable component of coastal ecosystems, especially of bays and estuaries. The great majority of these species is migratory, conducting long trips between Arctic and Sub-arctic breeding grounds and temperate and tropical wintering grounds. My general objective of this thesis was to analyze the foraging and pre

14. Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN
Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work

15. Influência da morfometria de lagos na diversidade fitoplanctônica
Morphometry is the measurement of various elements of form, and it includes methods to measure since the physical dimensions of an individual to the dimensions of a system. Morphological evaluations are good study mechanisms in many areas of science and work as fundamental tools from a microscopic scale to the dimensions of an ecosystem. In lakes, the unders

16. Hidrocarbonetos e esterois como indicadores de fontes e destino de matéria orgânica em sedimentos da Baía de Sepetiba, Rio de Janeiro
The inputs of organic matter derived from natural and anthropogenic sources to Sepetiba Bay were investigated by using aliphatic hydrocarbons and sterols in superficial sediments. Concentrations ranged from 0.26 to 2.65 μg g-1, <0.01 to 17.41 μg g-1 and 0.77 and 9.24 μg g-1 for n-alkanes, UCM (unresolved complex mixture) and total sterols, respectively. T

17. Caracterização ambiental de bancos areno-lamosos nos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo
On Rio Grande do Norte northern coast the process of sediment transport are intensely controlled by wind and sea (waves and currents) action, causing erosion and shoreline morphological instability. Due to the importance of such coastal zone it was realized the multi-spectral mapping and physical-chemical characterization of mudflats and mangroves aiming to

18. Proposta de uma tecnologia para levantamento da morfologia costeira com aplicaÃÃo de tecnologia GNSS
O ambiente costeiro à berÃÃrio natural para um grande nÃmero de espÃcies marinhas, principalmente onde ocorrem mangues e recifes, que funcionam como abrigo natural para a desova e inÃcio de vida de muitas espÃcies marinhas. A linha de costa està inserida nesse ambiente, pois representa o limite entre o mar e o continente, no alcance mÃximo das ondas

19. AplicaÃÃo de tÃcnicas de geoprocessamento para a anÃlise da evoluÃÃo da linha de costa em ambientes litorÃneos do Estado do CearÃ. / Application of GIS techniques for the analysis of changes to the shoreline in coastal environments of the State of CearÃ.
A forma intensiva e desordenada com a qual as atividades antrÃpicas vÃm ocupando as regiÃes costeiras aliadas as crescentes alteraÃÃes advindas dos processos oriundos das mudanÃas climÃticas globais estÃo afetando a dinÃmica natural dos ecossistemas, conforme pode ser evidenciado atravÃs de diversos indicadores ambientais, sendo um dos principais a

20. Evolução morfológica e sedimentológica do Arco Praial de Massaguaçú, litoral norte de São Paulo / Morfological e and sedimntological evution on Massaguaçu Bay Beach,North Costal of São Paulos State
This dissertation characterize the morphological and sedimentological evolution of Massaguaçú Bay Beach, São Paulo State, Northeast Brazil, in a Historical and events spatial-temporal scale. Massaguaçú Bay Beach is localized northward of Caraguatatuba Bay and has approximately 7.5Km length. The methodology consisted on the determination of the shoreline

21. Morfologia do perfil praial, sedimentologia e evolução histórica da linha de costa das praias da Enseada do Itapocorói Santa Catarina
The main objective of this work was to describe the morphologic evolution, sedimentary characteristics, and shoreline changes of the Itapocorói Bay, Santa Catarina Brazil, through the comparison of beach profile data and sediment samples taken before (80`s and 90`s) and after the nourishment projects (2007) at Alegre and Piçarras beaches.

22. Bertioga: paisagem, ambiente e urbanização / Bertioga: landscape, environment and urbanization
The purpose of this dissertation is to analyze the ways in which São Paulos shore landscape has changed throughout the years since the fifties, through a case-study: the city of Bertioga. Bertioga is defined by landscape architecture researchers as a forest municipality, which, in the year of 2008, still has most of its coastal ecosystems ecologic dynamics

23. Morfologia e sedimentologia das praias do litoral sul do municÃpio de Olinda - PE
The littoral of Olinda has spaces with coastal erosion since the last century. Trying to soften the erosion and stabilize the shoreline, a good range of engineering techniques were used in the last 88 years. During the 60s decade were made two breakwaters semi submerged in front of the Carmo beach and 38 groins along the 1,8 km of the Bairro Novo beach. The

24. Vulnerabilidade do litoral sul de pernambuco à erosÃo
This study proposes a methodology to estimate the vulnerability of coastal segments to erosion through a semi-quantitative approach and its application to 14 beaches on the southern coast of Pernambuco State, Northeast Brazil. Such analyses are important tools in the process of coastal management, aimed to establish priority areas for management. After resea
