ΣΥΜΒΟΛΗ ΣΤΗ ΜΕΛΕΤΗ ΤΩΝ ΒΡΥΟΖΩΩΝ ΤΟΥ ΑΙΓΑΙΟΥ

THE STUDY OF THE SYSTEMATIC ECOLOGY, ZOOGEOGRAPHY AND PALAEOECOLOGY OF THE BRYOZOAN FAUNA IN THE AEGEAN SEA IS THE MAIN PURPOSE OF THIS DISSERTATION . ON THE WHOLE 192 SPECIES WERE IDENTIFIED: (18 CTENTOSTOMATA - 131 CHEILOSTOMATA - 43 CYCLOSTOMATA). OF THESE 51 SPECIES ARE REFERRED FOR THE FIRST TIME FROM THE GREEK SEAS. A GREAT NUMBER OF SPECIES ARE RARE OR LITTLE KNOWN SPECIES REPORTED ONLY ONCE OR TWICE BEFORE. ONE SPECIES IS REFERRED FOR THE FIRST TIME FROM THE MEDITERRANEAN. A NEW SPECIES OF BRYOZOA IS ALSO DESCRIBED. THE STUDY OF THE ECOLOGY INCLUDES: A) THE DISTRIBUTION OF SPECIES BETWEEN DIFFERENT SUBSTRATA. B) QUANTITATIVE STUDY OF THE BRYOZOAN FAUNA ON POSIDONIA OCEANIA LEAVES. C) THE DISTRIBUTION OF THE COLONY TYPES BETWEEN DIFFERENT SUBSTRATA. A BATHYMETRIC DISTRIBUTION OF THE SPECIES AND THE COLONY TYPES WAS ALSO CARRIED OUT. THE ZOOGEOGRAPHICAL STUDY INDICATED A PREDOMINANCE OF ENDEMIC SPECIES . A HIGH PROPORTION OF TEMPERATE BOREAL ATLANTIC AND INDO-WEST PACIFIC SPECIES WAS ALSO DEMONSTRATED. THEANALYSIS OF SOME FOSSIL SAMPLES SHOWED THAT IT IS NECESSARY TO STUDY THE BRYOZOAN FAUNA IN PALAEOECOLOGICAL RESEARCH. STATISTICAL ANALYSIS WITH CLUSTERING AND ORDINATION METHODS SHOWED THAT THE MOST IMPORTANT FACTOR RESPONSIBLE FOR BRYOZOAN DISTRIBUTION IS SUBSTRATE TYPE, FOLLOWED BY SURFACE AVAILABLE AND DEPTH.
