Oceanographic Characteristics of Baía De Todos Os Santos, Brazil
Based on a vast set of in situ data, a first comprehensive overview of the oceanographic characteristics of Baı́a de Todos os Santos (BTS) is provided. BTS is the second largest coastal bay in Brazil (maximum area of 1223 km2 and average depth of 9.8 m), and is located in the northeast Brazil, in the vicinity of Salvador city. The circulation inside the bay is mostly tidally driven and does not ...
متن کاملHeavy metals in benthic organisms from Todos os Santos Bay, Brazil.
The marine ecosystems of Todos os Santos Bay (TSB, The State of Bahia, Brazil) have been impacted by the presence on its coast of a large metropolitan area as well as of chemical and petrochemical activities. Despite its ecological importance, there is a lack of scientific information concerning metal contamination in TSB marine biota. Thus, we analyzed concentrations of metals in four species ...
متن کاملEffect of Phase Shift from Corals to Zoantharia on Reef Fish Assemblages
Consequences of reef phase shifts on fish communities remain poorly understood. Studies on the causes, effects and consequences of phase shifts on reef fish communities have only been considered for coral-to-macroalgae shifts. Therefore, there is a large information gap regarding the consequences of novel phase shifts and how these kinds of phase shifts impact on fish assemblages. This study ai...
متن کاملBenthic Macrofauna Structure in the Northeast Area of Todos Os Santos Bay, Bahia State, Brazil: Patterns of Spatial and Seasonal Distribution
Structure of intertidal and subtidal benthic macrofauna in the northeastern region of Todos os Santos Bay (TSB), northeast Brazil, was investigated during a period of two years. Relationships with environmental parameters were studied through uniand multivariate statistical analyses, and the main distributional patterns shown to be especially related to sediment type and content of organic frac...
متن کاملOverview of the 20th century impact of trace metal contamination in the estuaries of Todos os Santos Bay: past, present and future scenarios.
This paper discusses the distribution patterns of trace metals in sediments and suspended particulate matter (SPM) in the three main estuaries of the Todos os Santos Bay (BTS), Brazil, during dry and rainy seasons. Data available up to 2012 was also reviewed to assess the status of contamination. For most elements, metal concentrations in sediments decreased from the tidal limits to the lower e...
