13. Estuary Adjacent to a Megalopolis as Potential Disrupter of Carbon and Nutrient Budgets in the Coastal Ocean
The goals were to estimate nutrients and carbon flow rates between Guanabara Bay and the adjacent coastal waters, to characterize the provenance of the exported/imported organic matter. Samples were collected from different depths over 25 h in two seasons at the bay entrance. Measurements included physicochemical parameters, nutrients, chlorophylls, dissolve

14. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

15. Mercury bioaccumulation and isotopic relation between Trichiurus lepturus (Teleostei) and its preferred prey in coastal waters of southeastern Brazil
A transferência trófica de mercúrio total (THg) e sua bioacumulação das espécies de presas para o peixe predador Trichiurus lepturus foi analisada em águas costeiras do sudeste do Brasil para avaliar a dinâmica de elemento traço neste sistema predador-presa. A relação isotópica (δ15N and δ13C) entre o predador e suas presas permitiu inferência

16. A comparative study of coastal and clinical isolates of
Pseudomonas aeruginosa Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance. The geographical distribution ofP. aeruginosa has revealed the existence of an unbiased genetic arrangement in terrestrial isolates. In contrast, there are very few reportsBraz. J. Microbiol..

17. Bryde's whale (Cetartiodactyla: Balaenopteridae) occurrence and movements in coastal areas of southeastern Brazil
Bryde's whales, Balaenoptera edeni Anderson, 1879, were observed on 17 occasions (N = 21 surveys) in the coastal waters off Rio de Janeiro in southeastern Brazil during austral summer through autumn 2014. Five whales were individually identified using photo-identification techniques. The mean interval between resightings for all individuals was 12.8 days, wi

18. Clustering of water bodies in unpolluted and polluted environments based on Escherichia coli phylogroup abundance using a simple interaction database
Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination

19. Thalassophryne nattereri fish venom: from the envenoming to the understanding of the immune system
Thalassophryne nattereri (niquim) is a venomous fish found off North and Northeast coast of Brazil, where it is known by the severity of the accidents involving humans. This review article is divided into four topics. The first one provides a brief description of the animal biology and its distribution off Brazilian coastal waters, the venom apparatus, signs

20. Eudistoma (Ascidiacea: Polycitoridae) from tropical Brazil
We studied material in collections from coastal intertidal and subtidal tropical waters of the Brazilian states of Paraíba, Pernambuco, Alagoas, Bahia, and Espírito Santo. We identified seven species of Eudistoma, of which two are new to science. Eudistoma alvearium sp. nov: colonies have fecal pellets around each zooid and zooids are 6-8 mm long with seve

21. Larval and adult density of the porcellanid crab Petrolisthes armatus (Anomura: Porcellanidae) in an Amazon estuary, northern Brazil
Petrolisthes armatus (Gibbes, 1850) is a porcellanid crab with a wide geographical distribution. In the present study we analyzed variations in the abundance of P. armatus adults and larvae over an annual cycle in the Marapanim estuary of the Amazon coastal zone, in the northeastern portion of the state of Pará, Brazil. Particularly, we focused on the prese

22. Seasonal variability of coastal water quality in bay of Bengal and Palk Strait, Tamilnadu, Southeast Coast of India
The aim of this work was to study the physicochemical parameters of water quality collected from 12 sampling stations from Topputhurai to Muthupet in Vedaranyam located on the southeast coast of India from January to December 2008. Results showed that the DO and nutrients were the maximum in the Bay of Bengal during the monsoon period. High concentration of
