가막만 동물플랑크톤 군집의 변동특성과 환경요인 = Environmental Factors and Variation Characteristics of Zooplankton Communities in Gamak Bay

다국어 초록 (Multilingual Abstract)

Spatio-temporal patterns in the zooplankton communities, physicochemical environmental factors, and dominant species were examined in Gamak Bay from April, July, September, and November, 2003. A total of 40 taxa were sampled with a mean abundance of total zooplankton ranging from 270~1,803 inds/m3. The most abundant species was Acartia erythraea, followed by Eurytemora pacifica, Podon polyphemoides, A. omorii, and Paracalanus parvus s. l during the study period. Multivariate analysis revealed significant differences in community structure among three regions: the middle part of the sampling area (B), sites 1, 2 (A) and other sites (C). The number of species and diversity (H') varied significantly among the three regions (p<0.05), but no differences in the mean abundances were observed (p>0.05). In order to investigate factors affecting the correlations between the abundance of dominant species, all zooplankton and environmental factors ware calculated using a correlation analysis. Of these, the abundance of dominant taxon showed positive correlation with seawater temperature, salinity and dissolved oxygen (p<0.05). In statistical analysis showed that the environmental factors influencing the variation of the communities were predominantly temperature, salinity, and dissolved oxygen.
