Dinoflagellate Cyst Changes and Winter Environmental Conditions in Vilaine Bay, Southern Brittany (France)

© Résumé refdoc =
"During the winter of 1989-1990, changes in dinoflagellate cysts and motile stages were studied respectively in sediment and plankton from Vilaine Bay (South Brittany, France). Special hydrological conditions (decreasing salinities, increased nutrient salts) related to the flood level of the Vilaine River in February 1990 were associated with a considerable increase in dinoflagellates in the water column. Cysts of species with estuarine affinities (Scrippsiella, Gonyaulax) had an elevated experimental germination rate at this time, whereas cysts in sediment were predominently Brigantedinium sp., Lingulodinium sp. and Spiniferites through-out the study period (...)"
