Abstract
The hydrothermal ecosystem is very unusual, yet little research has so far been conducted on meiofauna in hydrothermal zones. To identify the communities of both meiofauna and nematodes around the Onnuri Vent Field (OVF), we collected sediment from a hydrothermal zone in the OVF and deep-sea (DS) sediments (non-vent) outside the OVF. Sampling was conducted at seven stations using multiple corers on the Research Vessel ISABU in June 2018 and June–July 2019. The average densities of meiofauna ± standard deviation ranged from 21.7 ± 5.2 to 122.3 ± 45.0 individuals/10 cm2. The structure of the meiofaunal community differed between the OVF and DS. The two most dominant groups of meiofauna in both environments were nematodes and harpacticoids. Statistical analyses showed significant differences in the structure of the nematode community between OVF and DS. We also found that the richness, evenness, and diversity of nematodes in the OVF were lower than those in the DS. © 2021 Elsevier Ltd
