Algae of the Fiesa coastal lake, Slovenia | Alge v velikem ali priobalnem jezeru v Fiesi, Slovenija

anglais. In the years 1998, 1999 and 2000, samples were taken seasonally in the Fiesa lake situated next to the see - the only brackish lake in Slovenia. The purpose of the investigation was to establish qualitative species structure and relative abundance of the periphyton and the phytoplankton. In the years 1999 and 2000, some physical and chemical parameters were also measured. Altogether, 85 species and subspecies of algae (of six classes) were determined. Most of them belonged to Bacillariophyceae, followed by Cyanophyceae and Chlorophyceae. 19 species and subspecies are new to Slovenia, 15 of which belong to Bacillariophyceae and 4 to Cyanophyceae. Most of the new species and subspecies belonging to the genus Navicula. This is the first research into the Fiesa coastal lake's periphyton and phytoplankton carried out through a longer period of time.

slovène. V različnih letnih časih med letoma 1998 in 2000 smo vzorčevali perifitonske in planktonske alge v priobalnem jezeru v Fiesi - edinem brakičnem jezeru v Sloveniji. Namen raziskave je bil ugotoviti kvalitativno vrstno sestavo in relativno abundanco algnih združb. V letih 1999 in 2000 smo merili tudi nekatere fizikalne in kemijske parametre. Skupno smo določili 85 različnih vrst in podvrst iz šestih razredov alg. Po številu vrst in podvrst so prevladovale Bacillariophyceae, sledile so Cyanophyceae in Chlorophyceae. 19 vrst in podvrst je novih za Slovenijo, od tega pripada 15 vrst in podvrst razredu Bacillariophyceae, 4 vrste pa razredu Cyanophyceae. Največ novih vrst in podvrst pripada rodu Navicula . To je prva raziskava alg v priobalnem jezeru v Fiesi, ki je trajala daljše časovno obdobje in je zajela perifitonske in planktonske alge.
