마산만 조간대에서 서식하는 해조류 군집의 종조성 및 분포패턴을 2007년도에 계절별로 조사하였다. 조사기간 동안 총 42종의 해조류가 서식하였으며, 이 중 녹조류 5종, 갈조류 8종, 그리고 홍조류가 29종으로 나타났다. 우점종은 Enteromorpha linza, Ulva pertusa, Sargassum thunbergii, Gelidium amansii, G. divaricatum, Corallina pilulifera, Gracilaria textorii, 그리고 Polysiphonia morrowii으로 나타났다. 특히 우점종들은 수직분포가 뚜렷하였는데, 조간대 상부에는 U. pertusa, G. divaricatum가, 중부에는 E. intestinalis, E. linza, S. thunbergii, G. divaricatum이 우점하였다. 한편 하부에는 U. pertusa, Undaria pinnatifida, S. thunbergii, G. amansii, G. divaricatum, C. pilulifera이 주로 출현하였다. 조사기간 동안 출현한 출현종수는 계절 및 정점에 따라 변하였다. 겨울에 가장 많은 38종이 출현하였으며, 가을에는 28종으로 가장 적었다. 정점별로는 정점 4, 6에서 가장 많았으며, 정점 1, 2에서 가장 낮게 나타났다. 해조류 군집의 공간적 분포를 파악하기 위한 군집분석을 이용한 수지도 및 MDS 분석 결과에서는 해조류의 종조성 및 현존량이 각 정점의 지형적인 차이 및 조류, 해수의 움직임과 같은 물리해양학적인 특징에 의한 것으로 나타났다.

Abstract ▼ AI-Helper

The species composition and distributional patterns in marine benthic algae at intertidal zone in Masan Bay were investigated seasonally throughout 2007. A total of 42 species, 5 Chlorophyta 8 Phaeophyta and 29 Rhodophyta were recorded, and dominant species were Enteromorpha linza, Ulva pertusa, Sargassum thunbergii, Gelidium amansii, G. divaricatum, Corallina pilulifera, Gracilaria textorii, and Polysiphonia morrowii during study periods. Especially the vertical distribution of dominant algal species was remarkable: U. pertusa and G. divaricatum were dominated in the upper part, E. intestinalis, E. linza, S. thunbergii and G. divaricatum were in the middle part, and U. pertusa, Undaria pinnatiffda, S. thunbergii, G. amansii, G. divaricatum and C. pilulifera mainly occurred in the low part of tidal zone. The numbers of species were different with seasons and stations; Higher number of species was 38 species in winter, whereas 28 species were the lowest in fall. The number of species was higher at stations 4 and 6 Mile the lower value was at stations 1 and 2 than other stations. The spatial distributional patterns of marine benthic algal composition at each station in dendrogram and MDS ordination were due to the differences of local topography and physical characteristics such as currents and water movements.

문제 정의

The aims of present study was to examine the species composition and distributional patterns in marine benthic algae at intertidal zone in Masan Bay and to compare results between this study and other areas in the southern sea, Korea.

제안 방법

These samples were cleaned and then were identified according to Lee and Kang (1986, 2001), The marine benthic algae data was analysed to obtain the following community variables for local characteristics of algal community; R/P(Feldmann, 1937), C/P(Segawa, 1956), (R+C)/P(Cheney, 1977). The association of marine benthic algae species at each station was demonstrated with dendrogram of average linkage cluster analysis, and non-metric multi-dimensional scaling ordination(MDS) plotted each sample as a point on an ordination plot. The extent to which the composition of the different stations were either similar or different was examined visually.

대상 데이터

The sampling sites was exposed to open sea with a little steep slope in upper part but gentle in mid to lower part at intertidal zone in Masan Bay(Fig. 1). Water temperature was from 7.

성능/효과

A total of 42 species, 5 Chlorophyta, 8 Phaeophyta, and 29 Rhodophyta, were recorded at intertidal zone in Masan Bay(Table 1). These marine benthic algae occurred 38 species in winter, 33 spring, 36 summer, and 28 fall, respectively(Fig.
The dominant algal species were Enteromorpha linza, Ulva pertusa, Sargassum thunbergii, Gelidium amansii, G. divaricatum, Corallina piluliera, Gracilaria textorii, and Polysiphonia morrom during study pericxis. These species were occurred at intertidal zone in Masan Bay regardless of seasons.
zone in Masan Bay(Table 2). U. pertusa in Chlorophyta, and G. divaricatum in Rhodophyta occurred in the upper part, and E. intestinalis, E. linza in Chlorophyta, S. thunbergii in Phaeophyta, G. divaricatum. ChDrdria crassicaulis in Rhodophyta were in the middle part of tidal zone.
