Abstract

Morphological and ecological variations and inter-specific relationships of a red algal genus, Hypnea were investigated based on 34 populations belong to 7 species from Persian Gulf and Oman sea coasts. cluster analyses, principal component analysis and Canonical Correspondence Analysis were done. Statistical analyses indicated that characters such as special branches or branchlets, Position of tetrasporange and algae size had the most important role as diagnostic characters in intera-genus variation. In general 2 major clusters were formed. The first major cluster comprised of H. boergesenii. Second major cluster contains two subclusters. First subcluster is comprised of H. ecklonii, H. charoides, H. valentiae, H. musciformis and H. cornuta. The second subcluster is comprised of H. pannosa. Results showed that all invironmental factors except the average of annual water vapor pressure had effect on the morphological distribution of Hypnea populations.
