Abstract

The objective of this study was to clarify marine algae of 9 uninhabited islands in Gageo, Sinan-gun area, south western coast of Korea from July 2012. As a result, a total of 33 species – 1 green, 6 browns and 26 reds – was identified. As a result of performing cluster analysis according to the similarity index using PRIMER 5.0, it was largely divided into three main groups at 45% of significance. The vertical distribution pattern of intertidal marine algae represented three distinct zones; Ishige okamurae, Gloiopeltis furcata, Gloiopeltis tenax – Corallina pilulifera, Chondrus ocellatus – Sargassum fusiforme, Undaria pinnatifida, Corallina pilulifera.

한국 서남해안 신안군에 위치한 가거도 인근 9개 무인도서의 조간대에 생육하는 해조류를 파악하고자 2012년 7월 조사를 수행하였다. 조사결과 녹조류 1종, 갈조류 6종, 홍조류 26종이 출현하여 총 33종이 채집 및 동정되었다. PRIMER 5.0을 이용하여 유사도지수에 따른 군집분석을 실시한 결과 유의성 45%에서 크게 세 개의 그룹으로 나누어졌다. 가거도 인근 무인도의 조간대 생육하는 해조류의 수직분포를 보면 상부에서는 패(Ishige okamurae), 불등풀가사리(Gloiopeltis furcata), 참풀가사리(Gloiopeltis tenax), 중부에서는 작은구슬산호말(Corallina pilulifera), 진두발(Chondrus ocellatus), 하부에서는 톳(Sargassum fusiforme), 미역(Undaria pinnatifida), 작은구슬산호말이 우점하여 출현하였다.
