摘要 文章通过荧光显微分析和分子生物学分析方法,对斯瓦尔巴群岛周边海域微型浮游生物群落中的浮游细菌丰度、微型浮游植物丰度及优势种进行了重点调查,分析了微型浮游生物群落与海洋环境之间的相关性。结果表明,浮游细菌的丰度为4.2×105~1.2×106cells/ml,微型浮游植物的丰度为2.7×103~4.1×104cells/ml;微型浮游植物优势种包括微胞藻、微型海链藻和微型角毛藻。冰川融水会给附近海域带来陆源微生物,并在一定程度上促进微型浮游植物的生长,而海冰的存在和低温则是导致微型浮游生物丰度较低的主因。北冰洋升温和海冰(冰川)消融会导致海洋浮游生物群落的微型化,这种趋势会明显影响大型海洋生物对它们的利用效率,从而影响整个北冰洋海洋生态系统。
