p. 209 - 221 ETUDE DES COMMUNAUTES MYCOTIQUES DES EAUX LITTORALES ROUMAINES, CORRELEE AUX CONDITIONS ABIOTIQUES DE LA ZONE Mukader Apas et Elvira Cuingioglu Institute Roumain de Recherches Marines Constanta Abstract Observations were performed on mycotic communities dynamic concerning their correlations with eutrophic conditions. Biotic and abiotic data are discussed for a period of three years: 1978-1980. Ecology of the species of filamentous and yeasts are presented, too. Special attention is payed to: Candida diddensii, Geotrichum candidum, Cryptoccocus neoformans and Rhodotorula glutinis. Life cycle of the species is correlated with temperature and salinity values.
