Συμβολή στην έρευνα των πληθυσμών των βενθικών μακροφύκων (χλωροφύκων, φαιοφύκων και ροδοφύκων) του Θερμαϊκού Κόλπου
INVESTIGATION ON MARINE FLORA AND VEGETATION TOOK PLACE IN THERMAIKOS- GULF DURING THE YEARS 1969-1975. THE QUALITATIVE AND QUANTITATIVE COMPOSITION OF THE MARINE BENTHIC PHYTOCOMMUNITIES WERE INVESTIGATED (CHLOROPHYTA, PHAEOPHYTA AND RHODOPHYTA) WHICH GROW TO DEPTHS OF 4 METERS. 121 TAXA WERE IDENTIFIED FROM WHICH24 BELONGED TO CHLOROPHYTA, 29 TO PHAEOPHYTA AND 68 TO RHODOPHYTA . THE RATIO R/P 2,25. THUS THE CHLORIDIC CHARACTER IS RATHER NORTHERN MODERATE. THE RESEARCH ALSO INCLUDED THE SEASONAL PERIODICITY AND THE ANNUAL FLUCTUATION OF THE DIFFERENT BENTHIC MACROALGAE WITH A MAXIMUM BIOMASS DURING THE SUMMER MONTHS.15 PHYTOCOMMUNITIES WERE RECOGNIZED IN HARD SUBSTRATES AND 3 IN SOFT ONES. THREE (3) OF THE HARD PHYTOCOMMUNITIES BELONG TO THE NITRIPHILES WHICH GROW IN POLLUTED AREAS. THE CHLORIDIC ELEMENTS WHICH ARE OUTSTANDING ARE THE ENDEMIC MEDITERRANEAN ONES. THE DIACHRONIC RESEARCH OF THE PHYTOCOMMUNITIES SHOWED THAT PLANT COMMUNITIES SEEMED TO REDUCE DUE TO ANTHROPOGENIC STRESS IN POLLUTED AREAS.
