2010年夏季白令海小型底栖动物丰度与生物量初步研究
PRELIMINARY STUDY ON ABUNDANCE AND BIOMASS OF MEIOFAUNA IN THE BERING SEA IN SUMMER 2010
摘要
Abstract
Surface sediments were collected from seven stations in the Bering Sea during the fourth Arctic Chinese Nation-al Arctic Research Expedition in summer 201 0.Fourteen groups of meiofauna were detected in 1 0-cm sediment cores:Nematoda,Copepoda,Polycheata,Kinorhyncha,Amphipoda,Bivalvia,Cumacea,Ostracoda,Tanaidacea, Gastropoda,Isopoda,Ophiura,Tardigrada and others.The average abundance and biomass was 2658.89 ±2452. 86 ind·1 0cm -2 and 1 587.56 ±1 452.65 μg·dwt·1 0cm -2 ,respectively.Maximum abundance and biomass of 71 35.1 2 ±429.43 ind·1 0cm -2 and 4056.42 ±721 .33 μg·dwt·1 0cm -2 ,respectively,were both observed in shallow waters of the Bering shelf.At the same time,minimum abundance and biomass of 56.04 ±39.38 ind·1 0 cm -2 and 87.91 ±85.60 μg·dwt·1 0cm -2 ,respectively,were both observed in deep waters of the western Be-ring Sea basin.Nematoda accounted for 94.81 % of average abundance,followed by Copepoda (3.60%),and 93.44% of meiofauna were found in the upper 6 cm of surface sediments.The similarity index between meiofauna communities in shallow and deep waters was only 30.72%.Abundance in deep waters was an order of magnitude lower than abundance in shallow waters.Abundance and biomass were higher in shallow waters of the Bering shelf than in shallow waters of the China Sea and deep waters of the western Bering Sea basin.Pearson correlations anal-ysis between meiofauna and abiotic parameters indicated that abundance and biomass were negatively correlated with depth,sediment nutrient levels,and several diameter parameters.Meiofauna biomass may be more sensitive to environmental changes than abundance.关键词
