Abstract

Benthic marine algal flora and community structure at Chuksan on the mid-east coast of Korea were investigated seasonally from July 2007 to May 2009. Ninety-eight seaweed species were identified, including 13 green, 23 brown and 62 red algal species. The number of species found ranged between 33 and 63 among seasons. Two green (Ulva australis and Codium arabicum), three brown (Dictyota dichotoma, Sargassum fusiforme and Sargassum yezoense), and eleven red algae (Corallina pilulifera, Lithophyllum okamurae, Pachymeniopsis elliptica, Grateloupia filicina, G. cornea, Hildenbrandia rubra, Chondrus ocellatus, Acrosorium polyneurum, Chondria crassicaulis, Polysiphonia morrowii and Symphyocladia latiuscula) were observed throughout the survey period. Average marine algal biomass was $629.68g\;dry\;wt\;m^{-2}$ and it ranged seasonally from 119.30 to $1,660.96g\;dry\;wt\;m^{-2}$. The vertical distribution of marine algae was characterized by Corallina pilulifera and Sargassum spp. in the intertidal zone; Sargassum spp. at 1 m depth; Sargassum spp. and melobesioidean algae at 5 m depth; and melobesioidean algae at 10 m depth.

우리나라 동해안 중부의 축산항 지역에서 2007년 7월부터 2009년 5월까지 계절별로 조간대와 조하대 해조류의 종조성과 군집구조를 조사하였다. 2년에 걸친 조사를 통해 밝혀진 해조류는 총 98종(녹조류 13종, 갈조류 23종, 홍조류 62종)이었고, 조사시기별로는 33~63종의 범위로 나타났다. 이 가운데 녹조류 2종(구멍갈파래, 떡청각), 갈조류 3종(참그물바탕말, 톳, 왜모자반), 그리고 홍조류 11종(작은구슬산호말, 혹돌잎, 참도박, 참지누아리, 붉은까막살, 진분홍딱지, 진두발, 잔금분홍잎, 개서실, 모로우붉은실, 참보라색우무)의 16종은 모든 조사시기에 관찰되었다. 해조류의 단위면적당 생물량은 평균 $629.68g\;dry\;wt\;m^{-2}$이었으며, 계절별로 $119.30{\sim}1,660.96g\;dry\;wt\;m^{-2}$의 범위를 보였다. 조사지역 해조군집의 수직분포는 조간대에서 작은구슬산호말과 모자반류, 조하대 1 m에서 모자반류, 5 m에서 모자반류와 무절산호조류 그리고 10 m에서 무절산호조류로 대표되었다.
