Seasonal hydrochemical variation in a tropical coastal lagoon (Açu Lagoon, Brazil).
Hydrochemical conditions in the Açu Lagoon are described using spatial and temporal variations of various limnological variables (water temperature, dissolved oxygen, electric conductivity, total alkalinity, carbon dioxide, dissolved and total nutrients (N, P and Si), and chlorophyll a). Collected data was used in order to understand the structure and functioning of an enclosed coastal lagoon s...
متن کاملEnvironmental changes and zooplankton temporal and spatial variation in a disturbed Brazilian coastal lagoon.
The Imboassica lagoon, located in the Municipality of Macaé (RJ), is separated from the sea by a sand bar, and its surroundings are partially occupied by residential areas. This coastal lagoon has undergone environmental degradation due to sewage input and artificial sand bar openings. The temporal and spatial variation of environmental variables and zooplankton were studied monthly for four ye...
متن کاملChanges of macrobenthos composition under different ENSO cycle conditions on the continental shelf off central Chile
The course of environmental conditions and shelf macrobenthic communities off Central Chile ( 361S) during the strong 1997–98 El Niño (EN) event is compared with a subsequent and basically ‘‘normal’’ period (2002–2003). Changes in macrofaunal community, feeding mode structure, and biomass size spectra are contrasted over time with changes in oceanographic and sediment settings, in order to asse...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Identification of Cyanobacteria in a Eutrophic Coastal Lagoon on the Southern Baltic Coast
Cyanobacteria are found worldwide in various habitats. Members of the picocyanobacteria genera Synechococcus and Prochlorococcus dominate in oligotrophic ocean waters. Other picocyanobacteria dominate in eutrophic fresh or brackish waters. Usually, these are morphologically determined as species of the order Chroococcales/clade B2. The phytoplankton of a shallow, eutrophic brackish lagoon was i...
