1. Morfodinâmica associada entre duna, praia e zona submarina como subsídio a adequada ocupação do espaço costeiro na Praia do Peró - RJ. / Morphodynamics associated between dune, beach and underwater area as an aid to proper occupation of coastal space in Praia do Pero - RJ.
The coastline offers a veritable mosaic of diversity in coastal landforms, which enable the development of a number of different economic activities. Coastal environments are highly dynamic and involve a complex series of continental and oceanic processes. The beach of Pero, located between Cape Buzios and Cabo Frio, Rio coast, appears as an area distinct fr

2. Nesting of Phrynops geoffroanus (Testudines: Chelidae) on sandy beaches along the Upper Xingu River, Brazil
This work presents the first data on incubation temperature of Phrynops geoffroanus (Schweigger, 1812) in a natural environment, and provides information on nest predation, hatching success and size of offspring born in the nests on sandy beaches along the Upper Xingu River. Thirty-one P. geoffroanus nests were found, of which eleven were completely predated

3. Variabilidade morfodinâmica das praias oceânicas entre Imbé e Arroio do Sal, RS, Brasil
The morphodynamic variability of the oceanic beaches between Imbé and Arroio do Sal towns, Rio Grande do Sul State, Brazil, was investigated by means of periodic beach profiling combined with the interpretation of granulometric and hydrodynamic regime data. A seasonal trend in the hydrodynamic regime, in the distribution of the sediments and in the morphome

4. Morfologia e sedimentologia da Plataforma Continental Interna entre as Prais Porto de Galinhas e Campos-Litoral Sul de Pernambuco, Brasil
The analysis of geomorphic and sedimentological characteristics of the inner continental shelf is an important propriety to studies of the coastal zone since they inform the conditions of the sea bottom, the predominant features and the types of associated sediments. Associated to morfodinamic study it can, for example, identify predisposed areas to erosive

5. Nutrientes (K, P, Ca, Na, Mg e Fe) em sedimentos (solos aluviais) e cultivares (feijão e milho) de praias e barrancos de rios de água branca: a bacia do purus no estado do Acre, Brasil
The present research highlights the macronutrient abundance in the sediments of beaches and cliffs and cultivates in the river Purus and flowing, southwest of Amazon. The concentrations found in leaves and bean seeds and corn leaves reflect the mineralogical and chemical nature of those rich sediments in K2O and Na2O, which are formed by smectite, illite and

6. Relação solo-relevo-substrato geológico na planíce costeira de Bertioga (SP) / Soil-relief-geologic substract relationship on the coastal plain of Bertioga (SP)
Knowledge of the chronology, relief, geology and soils in sedimentary coastal environments is relevant for their interpretation, reconstitution and conservation. In Bertioga, São Paulo State Brazil, several sections of the Pleistocene and Holocene morphostratigraphic costal plain units are preserved in the landscape. This thesis seeks the perception of the

7. O litoral de JoÃo Pessoa (PB), frente ao problema da erosÃo costeira
The JoÃo Pessoa- PB coast like other places of the Brazilian Northeastern, show erosive problems associated to natural process and a urban disorder occupation, that happened from the 70 decade, of last century, when the city began expanding towards the beaches. This work was onjective to classify the study area in relation to coastal erosion vulnerability.

8. AvaliaÃÃo ambiental e percepÃÃo dos usuÃrios sobre os efeitos das obras de proteÃÃo de costa nas praias da Casa Caiada (Olinda) e Janga (Paulista)
The coastal zones and special the beaches are dynamical and fragile regions in a continuous change. The high population concentration in these areas results in a pressure increment upon natural resources and increased risk of environmental degradation. The coast of the Sate of Pernambuco, is experiencing coastal erosion that has many times being mitigated wi

9. 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

10. Tailings dams beaches: characteristics and sedimentation analysis. / Praias de barragens de rejeitos de mineração: características e análise da sedimentação.
A mineração é formada pelo conjunto de ações de lavra, concentração e transformação do minério para múltiplas finalidades. O resultado da explotação de diversos minérios, após seus beneficiamentos, é a produção de rejeitos, em quantidades variáveis. Características diversas como vazão e conteúdo de água na polpa, densidade, arredondame

11. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

12. SANDY BEACH MORPHODYNAMICS AND MACROBENTHIC COMMUNITIES IN TEMPERATE, SUBTROPICAL AND TROPICAL REGIONS - A MACROECOLOGICAL APPROACH
A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and
