1. The structuring role of macrophytes on plankton community composition and bacterial metabolism in a large subtropical shallow lake
Resumo Objetivo Nós objetivamos investigar mudanças nos principais grupos do plâncton (bacterioplâncton, fitoplâncton e zooplâncton) e no metabolismo do bacterioplâncton ao longo de um transecto cobrindo uma zona litorânea dominada por macrófitas para uma zona pelágica dominada por fitoplâncton na lagoa Mangueira, uma lagoa extensa, rasa e subtro

2. Mortality due to cutaneous melanoma in south region of Brazil: a spatial approach
Abstract: Background: Cutaneous melanoma is a skin cancer with low incidence but high mortality rates. The South region of Brazil has the highest death rates by melanoma per 100,000 inhabitants of the country. Little is known about the spatial distribution of this malignancy in southern Brazil. Objectives: Identify the spatial patterns of deaths from cutan

3. Cyanobacteria from coastal lagoons in southern Brazil: non-heterocytous filamentous organisms
This study describes and illustrates non-heterocytous filamentous cyanobacteria found in lagoon systems on the coastal plains of Rio Grande do Sul State. Collections were carried out in different freshwater bodies along the eastern (Casamento Lake area) and western (Tapes City area) margins of the Patos Lagoon (UTM 461948-6595095 and 542910-6645535) using a

4. Cyanobacteria from coastal lagoons of Southern Brazil: coccoid organisms
Considering the great ecological importance of the cyanobacteria and the need for more detailed information about these organisms in Brazilian waters, this paper provides taxonomic information about the unicellular cyanobacteria flora in lagoon systems along the coastal plains of Rio Grande do Sul State. Sampling was performed in different freshwater bodies

5. Ecological distribution of the shrimp Pleoticus muelleri (Bate, 1888) and Artemesia longinaris Bate, 1888 (Decapoda, Penaeoidea) in the southeastern Brazilian littoral
The relationship between species abundance and environmental factors such as the bottom water temperature and salinity, the texture and organic matter content of the sediment and the distribution of Pleoticus muelleri and Artemesia longinaris were investigated. Specimens and samples of abiotic factors were collected monthly from May 2008 to April 2010 at 4 l

6. Effects of natural banks of free-floating plants on zooplankton community in a shallow subtropical lake in Southern Brazil
The aim of this study was to test the effects of natural free-floating plants on zooplankton distribution in a shallow subtropical lake. First, the hypothesis that free-floating plants have an effect on physico-chemicals, leading to a decrease on nutrient availability and influencing the phytoplankton biomass and zooplankton community was tested. Second, the

7. Assembléias de diatomáceas em sedimentos holocênicos no estremo sul do Brasil : reconstruções paleoambientais
This paper describes the diatom assemblages present in a sediment profile in the Lagoa do Peixe, Middle Littoral of Rio Grande do Sul, in order to make the palaeoenvironmental reconstruction and identify periods of increased marine influence and hydrodynamics, as a consequence of changes sea level occurred during the Holocene. The drill core T09 was selected

8. Dinâmica da desembocadura do rio Itanhém, Alcobaça, BA / Morphodynamics at the Itanhaém Inlet, Alcobaça, BA
The morphodynamic processes at inlet systems are related to a variety of forcing conditions that create unique hydrodynamic conditions. The interaction of tidal currents, wave conditions, and river discharge at different levels result in complex dynamic patterns. The present work aims to understand the processes that control the dynamics of the Itanhaém Riv

9. Geomorfologia e potencial de preservação dos campos de dunas transgressivos de Cidreira e Itapeva, litoral norte do Rio Grande do Sul, Brasil
The association of several favorable factors (high supply of fine sand to the beach, appropriate wind regime, lowland topography) has resulted in the development of a wide transgressive dunefield that stands out as a fundamental element in the coastal landscape of Rio Grande do Sul, southern Brazil. Along the northern littoral of the state, most of this orig

10. Efeitos da radiação ultravioleta-b sobre a morfisiologia de kappaphycus alvarezii (DOTY) doty ex P. Silva (gigartinales) variantes pigmentares verde e vermelha
The effects of ultraviolet radiation in the biological relevant wavebands of UV-A (315#400 nm) and UV-B (280#315 nm) on algae have become an important issue as a man-made depletion of the protecting ozone layer has been reported. However, experimental designs to investigate this issue are manifold and the target organisms are extremely diverse. Data are incl

11. Um estudo sobre a produÃÃo capitalista do espaÃo turÃstico e as perspectivas de desenvolvimento local na Praia de Gamela
The aim of this study was to discuss the role of tourism while a vector of the northeast littoral`s space (re)production. As a case was taken the reality Gamela`s beach and the Aver-O-Mar traditional fisherman`s community, located at Pernambuco`s Southern Littoral. The touristification process of the space started with the tourism ideology that tourism is th

12. Comunidade de CrustÃceos DecÃpodos InfralitorÃneos dos Recifes da Praia de Porto de Galinhas (PE)
Northeastern Brazilian coral reefs, as found in Porto de Galinhas beach â PE, are known as areas of complex and diverse biological interactions and high biological productivity (primary productivity). In addition, they represent a reproductive zone, and serve as nursery, shelter and alimentation source for a major part of the marine fauna. Porto de Galinhas
