Abstract

The relationships among total epiphytes, algal epiphytes and eelgrass ($Zostera$ $marina$ L.) were studied at eelgrass medows from July, 1998 to July, 1999 in Yulim-ri, Yeosu, Korea. Epiphytic diatoms on eelgrass leaves were observed from July to December 1998. From the results of this study, we inferred the following three (3) conclusions : 1) As eelgrass grew older, biomass of epiphytes increased, according to relationships between the leaf length and area of eelgrass and biomass (DW, AFDW and Chl. $a$) of epiphytes. 2) According to the ratio of dry weight, ash-free dry weight and Chlorophyll of epiphytes, the algae with calcareous or siliceous skeletons, such as coralline algae or diatoms, were dominated in the epitphytic algae community. 3) The autotrophic index (AI) calculated from AFDW and Chl. $a$ of epiphytes varied from 151 to 375. However, the period of autotrophic community was shorter than heterotrophic community and the value of AI was high. From these results, we inferred that heterotrophic community, including detritus or microorganisms were dominated in the most of research period.

본 논문은 잘피의 성장과 부착생물과의 관계, 그리고 부착생물간의 관계를 이해하고자 실시된 연구로서 여수시 돌산읍 율림리에서 1998년 7월에서 1999년 7월까지 총 13개월 동안 실시되었다. 연구 결과를 토대로 다음과 같은 세 가지 결론을 얻을 수 있었다. 1) 잘피 잎의 면적과 부착 생물의 현존량과는 정상관관계를 나타냄으로써 부착가능 면적이 넓어지게 되면 부착생물의 현존량이 증가함을 확인할 수 있었다. 이것은 해초의 외적인 성장이 증가할수록 부착생물이 부착할 수 있는 시간적 가능성이 증가할 뿐만 아니라 부착이 가능한 면적이 확대되는 기회를 제공해 줄 수 있다. 2) 부착생물의 건중량에 대한 무기물량 및 유기물량의 비율과 엽록소 양과의 상관관계를 살펴볼 때, 부착조류의 경우 석회홍조류나 규조류와 같이 무기물의 비율이 높은 조류의 현존량이 녹조류나 갈조류와 같은 조류보다 상대적으로 높은 것으로 나타났다. 3) 독립영양지수 (AI, Autotrophic Index)를 통해 살펴본 부착생물의 군집은 약 2개월의 종속영양군집이후 1개월의 독립영양군집이 나타나는 현상을 보였으나, 독립영양생물을 위주로 한 군집의 유지기간이 짧고 지수의 값이 높은 것을 고려할 때, 유기물질 또는 미생물 등을 위주로 한 종속영양생물의 군집이 우점한다고 유추할 수 있었다.
