Abstract

Abstract

Meiofaunal communities and the relationships with environmental variables in the northern East China Sea and its adjacent area were studied in the present paper based on the material collected from 20 sites in September and December, 2016. About 16 meiofaunal groups were identified with nematodes being the most dominant group, followed by copepods, kinorhynchs and polychaetas. The average abundances of meiofauna were (1 758±759) ind./(10 cm²), and (2 011±1 471) ind./(10 cm²) in September and December, respectively. The average biomasses of meiofauna were (1 216.4±464.7) μg/(10 cm²) and (1 143.0±755.0) μg/(10 cm²) in September and December, respectively. Results of CLUSTER analysis show that meiofaunal communities can be divided into two main groups, one was the offshore group, composed of stations in the offshore area, another group was the coastal group, composed of stations in the coastal area. However, the highest value of abundance always occurred in the depth about 60 m isobath where the salinity and temperature showed the characters of Kuroshio Current implying the intrusion of Kuroshio. We suggest that the intrusion of Kuroshio Current is the main cause of the increase of meiofaunal abundance, which can be treated as a response of meiofauna to the intrusion of Kuroshio, around the 60 m isobath. The high abundance of meiofauna may be explained by dissolved oxygen brought by the Kuroshio waters, and high primary production of water column benefitted from the supplying of phosphorus of the Kuroshio waters.
