Collos, Yves, BEC, Beatrice, JAUZEIN, Cecile, ABADIE, Eric, LAUGIER, Thierry, Lautier, Jacques, ...

Time series data have been examined in Thau lagoon (Southern France) from 1972 to 2006 for water temperature, salinity, nutrients and from 1987 to 2006 for phytoplankton. A first main trend...

Contribution of several nitrogen sources to growth of Alexandrium catenella during blooms in Thau lagoon, southern France (2007)

COLLOS, Y, VAQUER, A, LAABIR, M, ABADIE, Eric, LAUGIER, Thierry, PASTOUREAUD, Annie, ...

A monitoring program with a weekly sampling frequency over a 15-month period indicates that urea concentrations above a certain threshold level may trigger the blooms of Alexandrium catenella in Thau...

Pheopigment dynamics, zooplankton grazing rates and the autumnal ammonium peak in a Mediterranean lagoon (2005)

COLLOS, Yves, HUSSEINI RATREMA, Julie, BEC, Béatrice, VAQUER, André, HOAI, Thong Lam, ROUGIER, Claude, ...

The dilution technique was used to estimate chlorophyll and pheopigment, net and gross production as well as zooplankton grazing over a 12-month period in a coastal lagoon in Southern France....

SOUCHU, Philippe, VAQUER A, André, COLLOS, Yves, LANDREIN, Sonia, DESLOUS-PAOLI, Jean-Marc, BIBENT, Bertrand

Thau lagoon is a Mediterranean shellfish ecosystem with large biomasses of oysters growing in waters with high residence time due to low tidal ranges, The influence of filter feeders (oysters and...

Coastal eutrophication: A review of the situation along the French coasts (2001)

MENESGUEN, Alain, AMINOT, Alain, BELIN, Catherine, CHAPELLE, Annie, GUILLAUD, Jean-Francois, JOANNY, Michel, ...

In order to be able to count the cases of coastal eutrophication and to propose methods to monitor as well as to reduce these phenomena, first of all it is necessary to precisely define the word...
