Foraminifers are increasingly used as bioindicators of Seasonal variations of brackish Foraminifera in the Patos Lagoon. Their community structure provides information on the general characteristics of the environment, especially in highly changing paralic environments (e.g., Hayward and Hollis, ), and some species are sensitive to specific environmental by: biraquera lagoon, a typical temporarily open/closed coastal lagoon of Brazilian Southern Ecoregion (SBE): (a) during isolation from the sea, lagoon.

Two circumpolar ocean currents move in opposite directions at this location. The more poleward or southern current, the East Wind Drift, moves east to west, driven by the Polar Easterlies. The southern limit of the species was formerly considered to be Morocco, with accidental strays south to Cape Blanc (CLOFNAM, ll2).

An extensive survey of helminth parasites in fish and shellfish species from Santa Gilla, a brackish water lagoon in southern Sardinia (western Mediterranean), resulted in the identification of 69 helminth parasite taxa and/or species from 13 fish species (n= ) and seven bivalve species (n= ) examined between September and July   The Patos Lagoon basin is a large ( km(2)) and complex drainage system in southern Brazil.

The lagoon is km long and 60 km wide, covering an area of 10 km(2). The exchange of water with the Atlantic Ocean occurs through a 08 km wide and 15 m deep inlet, fixed by 4 km long jetties, at the southernmost part of the Patos Lagoon.

Another restricted lagoon was studied on the southern Brazilian coast, the Cananeia-Iguape lagoon (Eichler et al., ). It is a deep (up to 12 m) lagoon with a salt wedge due to freshwater inflow from several small coastal rivers (Miyao et al., ; Eichler et al., ) (Table 1).

Coastal lagoons are a highly unique productive ecosystem, biologically conserving units located onshore in thickly populated areas from tropics to artic.

Each lagoon and coastal wetlands along east coast vary in their characteristics seasonally and geo especially. Many lagoons are under threat in countries like India, Brazil, Australia, Sri-Lanka due to hydrological, anthropogenic. The modelled Humber plume retains % of the freshwater dissolved inorganic nitrogen, % of the freshwater phosphate and % of the freshwater silicate input over the simulated seasonal cycle.

The remainder is transported into the southern North Sea in either dissolved or particulate form. The reliability of these results is discussed.
