The spotted seal ( Phoca largha ), which primarily inhabits the cold waters of the Northwest Pacific Ocean, including China's northern Bohai and Yellow Seas, exhibits age‐related variations in its fecal microbiome that remain poorly understood. This study investigated the fecal microbiome composition and predicted functional capabilities between adult and juvenile spotted seals. Firmicutes was the dominant phylum in both group...

Crinoids, as integral echinoderms, play a crucial ecological role in benthic communities, serving as significant indicators reflecting the health of marine ecosystems. However, the phylogenetic relationships within crinoids are unclear. More molecular data can help to facilitate biodiversity assessment and elucidate evolutionary relationships by the phylogenetic tree. In this study, 13 complete mitochondrial genomes of the Cri...

The dilution experiment technique was used in two cruises in July-August (summer) and October-November (autumn) 2020, with a total of 14 stations. The grazing impact of microzooplankton on phytoplankton in the interior of Bohai Bay was comprehensively investigated. We compared phytoplankton growth rates (μ 0 ) and microzooplankton grazing rates (m) spatially (distance between experimental stations and shore far vs. near) and s...

To examine the spatial pattern and controlling factors of the primary productivity (PP) of phytoplankton in the eastern Indian Ocean (EIO), deck-incubation carbon fixation (a 14 C tracer technique) and the related hydrographic properties were measured at 15 locations during the pre-summer monsoon season (February–April 2017). There are knowledge gaps in the field observations of PP in the EIO. The estimated daily carbon produc...
