제주도 조하대의 해조류

Abstract

This study investigated the subtidal zone dividing into four sites in Jeju Island from February to August, 2006. The Coralline algae covered the benthic rocky shore of the four site's subtidal zone. Cladophora wrightiana, Colpomenia sinuosa, Galaxaura falcata ,Gelidium amansii formed each group on that. In addition, Ecklonia cava and Undaria pinnatifida were founded there. 71 taxa which involved 10 green algae, 21 brown algae, 40 red algae were collected in four site's subtidal zone. To be classified by sites, Kangjeong had 37(3 green algae, 14 brown algae, 20 red algae), Bukchon had 35(8 green algae, 9 brown algae, 18 red algae), Onpyong had 13(3 green algae, 4 brown algae, 6 red algae) and Yongsu had 39(3 green algae, 14 brown algae, 22 red algae). The results indicated that it exists different ecological structure of marine plant because the similarity of each site's subtidal marine plant is low.
