1. Pessoas, manatins e o ambiente aquático na América moderna: confluência e divergência nas interações históricas entre humanos e animais
RESUMO Com uma distribuição geográfica histórica alargada em zonas costeiras, ambientes de transição e fluviais do Oceano Atlântico tropical, o manatim (manati das Índias Ocidentais, peixe-boi ou iguaragua do Brasil colonial) era bastante valorizado. As fontes documentais e iconográficas dos séculos XVI e XVII mostram-nos que era usado como aliment

2. Environmental services in watersheds with small declivity: fluvial marine plains
Resumo Planícies fluvio-marinhas abrigam ambientes com reduzida declividade, porém com ofertas diferenciadas de atributos ambientais que podem constituir relevantes serviços ecossistêmicos nas suas bacias hidrográficas, que podem ser transformadas em oportunidades para o desenvolvimento de pagamento de serviços ambientais. O estudo espacializou parte d

3. Acanthaceae Juss. no Parque Estadual Restinga de Bertioga, Estado de São Paulo, Brasil
RESUMO A vegetação de restinga é formada por comunidades costeiras diversificadas, determinadas por fatores abióticos, como a topografia e a influência flúvio-marinha. As informações sobre a composição florística das restingas do litoral central do Estado de São Paulo são deficientes, poucos trabalhos referem a ocorrência de Acanthaceae nesse e

4. Characterization of dioxygenases and biosurfactants produced by crude oil degrading soil bacteria
ABSTRACT Role of microbes in bioremediation of oil spills has become inevitable owing to their eco friendly nature. This study focused on the isolation and characterization of bacterial strains with superior oil degrading potential from crude-oil contaminated soil. Three such bacterial strains were selected and subsequently identified by 16S rRNA gene sequen

5. Polyplacophora (Mollusca) from reef ecosystems and associations with macroalgae on the Coast of Alagoas, Northeastern Brazil
ABSTRACT Brazilian marine molluscs, especially Gastropoda and Bivalvia, are relatively well studied. However, information on the class Polyplacophora is more scarce, particularly on reef-dwelling forms. This study aimed to qualitatively and quantitatively analyze aspects of polyplacophorans from reef ecosystems and their associations with macroalgae on the c

6. Avaliação da atividade quitinolítica por bactérias do gênero Aeromonas isoladas do ecossistema marinho. / Chitinolytic activity evaluation by Aeromonas genus strains isolated from the marine ecosystem.
Bactérias quitinolíticas desenvolvem papel fundamental no ciclo de nutrientes através da degradação da quitina no ecossistema marinho. A hidrólise da quitina é realizada por quitinases, as quais podem ser utilizadas em processos biotecnológicos. O estudo teve como objetivo avaliar as condições ótimas de cultivo de bactérias quitinolíticas seleci

7. Marcadores orgânicos moleculares como ferramentas no monitoramento ambiental: Avaliação da distribuição de Alquilbenzeno Lineares (LABs) em organismos e sedimentos, como indicativo de exposição ao esgoto em áreas costeiras / Organic molecular markers as tools in environmental monitoring: Evaluation of Linear Alkylbenzene (LABs) distribution in organisms and sediments, as indicative of exposure to sewage in coastal areas
The sewage disposal in coastal areas can cause impacts to marine life, altering the balance of the ecosystem and biodiversity and causing serious diseases in humans. In this study, the concentration of a set of molecular markers for the introduction of organic sewage into the marine environment: linear alkylbenzene (LAB), in samples of sediment, oysters (Cra

8. Decapod crustaceans from a marine tropical mangrove ecosystem on the Southern Western Atlantic, Brazil
The purpose of the present study was to investigate the biodiversity, relative abundance and frequency of decapod crustaceans in the marine mangrove ecosystem at Gaibu Beach, Pernambuco State, Brazil. A total of eight samples were taken: four in the rainy season (August 2010) and four in the dry season (February 2011), during spring low tides and according t

9. AvaliaÃÃo econÃmica e ambiental dos sistemas de pesca utilizados nos MunicÃpios de Aracati e Icapuà -CE: subsÃdios para gestÃo / Economic evaluation and environmental systems fish used in the municipalities of Aracati and Icapuà - CE: support for management
Given the current global crisis in the fishing sector new approaches and strategies for fisheries management have arised, such as ecosystem management, co-management and marine protected areas. Artisanal fisheries, mostly in the Northeast Brazil, have an undeniable importance for fish production and rent. Within this framework of new management possibilities

10. Reproductive period of the swimming crab Callinectes danae at the Santa Cruz Channel, a highly productive tropical estuary in Brazil
The aim of this study was to analyze reproductive aspects of Callinectes danae in one of the most productive estuarine systems in the Northeast Brazil, Santa Cruz Channel. A total of 1.573 individuals, being 756 females (23 ovigerous) and 817 males were examined from January to December 2009. Mature males and females, as well as couples of C. danae, occurred

11. Análise ecológica e econômica da pesca marinha por meio de indicadores multiespecíficos / Ecological-economics analysis of marine fishery with multispecies indicators
Changes in marine ecosystems and fisheries resources due to the fishing pressure can be detected by multispecies indicators. These are, usually, applied to catch or landing time series, jointly the resources bio-ecological data. However, there is an alternative approach, based on market data that could be used. In this study, several multispecies indicators

12. Caracterização de leveduras do gênero Trichosporon isoladas de três regiões costeiras do Estado de São Paulo / Characterization of Trichosporon spp. Isolated from three coastal regions of São Paulo State, Brazil
Coastal regions are being threatened because they have a predatory and uncontrolled exploitation of natural resources by changing biodiversity. Yeasts are part of the marine ecosystem, though some species are associated with superficial mycoses, subcutaneous and / or systemic. The objective of this study was to quantify yeast, isolation and Trichosporon spp.
