Bacterioplankton diversity in different littoral habitats along the coast of the northern Shandong peninsula
摘要
Abstract
The community structure and diversity of bacterioplankton from different littoral habitats around the Shandong Peninsula were investigated by constructing 16S rDNA clone libraries. To visualize the differences in the community structure among habitats, non-metric multidimensional scaling (NMDS) was conducted on the basis of a Bray–Curtis similarity matrix. Analysis of similarity (ANOSIM) was performed to test for statistically significant differences. There was a significant difference between samples from littoral zones and coastal waters. In comparison, bacterioplankton samples in littoral zones displayed higher abundance and diversity, particularly in seagrass areas. Proteobacteria dominated in the muddy flat, rocky, and sandy habitats of Yantai; wetlands inhabited by Suaeda in the Yellow River Delta; and wetlands with seagrass in Swan Lake. Bacteroidetes was the most abundant in wetlands inhabited by Sparina in the Yellow River Delta. The results suggest that seasonal variation, the type of vegetation, and the source of organic matter may be key factors regulating the bacterioplankton community structure in different littoral and coastal habitats.关键词
