碩士 / 國立臺灣海洋大學 / 海洋環境化學與生態研究所 / 99 / To compare bacterial community composition of two distinct biomes in the South China Sea, the CARD-FISH (CAtalyzed Reporter Deposition Fluorescence In Situ Hybridization) analysis were conducted at a station located in oligo-trophic open ocean (i.e. the SEATS station; 18 oN, 116 oE) and stations located inside a shallow meso-trophic atoll (i.e. the Dong-Sha atoll) during autumn 2010. The results indicated significant differences of community structure and bacterial production (BP) in these two study sites. The Dong-Sha atoll was characterized with high BP (10.7±7.2 mgC m-3 d-1) and was dominated by γ-proteobacteria (34 % of total cell counts). The SEATS station was characterized with low BP (0.9±0.3 mgC m-3 d-1) and was dominated by α-proteobacteria (35 % of total cell counts). Bacterial production in both sites showed no correlation with total cell counts. Principal component analysis indicated that in the SEATS station, there was no correlation among α-, β- and γ-proteobacteria, and none of them were correlated with BP. However, all there above mentioned bacterial groups in the Dong-Sha atoll were highly correlated with each other, and all showed positive correlations with BP. The partial regression coefficient of β-proteobacteria (0.63) on BP was ~5-fold of those of α- (0.13) and γ-proteobacteria (0.11), indicating that the variation of BP was primarily determined by β-proteobacteria in the Dong-Sha atoll.
