Summary: The dilution experiment technique was employed in two cruises conducted in July-August and October-November 2020, with 14 stations in total. The study comprehensively investigates the grazing impact of microzooplankton on phytoplankton in the interior of Bohai Bay. Spatially and seasonally, both the microzooplankton grazing rates (m) and phytoplankton growth rates (& mu;(0)) were significantly higher in summer compared to autumn, and the growth rate of phytoplankton was positively correlated with temperature. The ratio of microzooplankton grazing rate to phytoplankton growth rate (m/& mu;(0)) showed no significant spatial and seasonal differences, indicating a consistent daily consumption of primary production by microzooplankton in the two seasons. Therefore, the research highlights a close coupling between microzooplankton grazing and phytoplankton growth in the Bohai Bay.

Summary: Understanding the variability in stable isotope ratios of small pelagic fish is crucial for isotopic studies of marine predators. This study investigated the variability of Japanese sardine isotope ratios in the western North Pacific and its marginal seas, and found that baseline variations are the main determinant of sardine isotope composition. The study also revealed that adult sardines showed less geographic variation compared to larvae and juveniles, and the isotope ratios of juvenile sardines in the Pacific offshore reflected the baseline in the neighboring southern region.

Summary: This study investigated the variations in water quality parameters and trophic status of a multipurpose reservoir in response to changing intensity of monsoon rain. The reservoir generally maintained mesotrophic conditions, with phosphorus concentrations not showing strong correlations with precipitation. Phytoplankton growth was mainly limited by zooplankton grazing, and the intensity of the monsoon season affected cell concentrations and community structure in the reservoir.

Summary: The spatial distribution and seasonal variation of near-inertial kinetic energy (NIKE) in the upper Ross Sea (RS) are examined using a sea ice physical-biological coupled model. The annual-mean surface and mixed layer-integrated NIKE have large values at specific areas in the RS, mainly influenced by near-inertial wind stress magnitude (NIWSM) as the energy source. The presence of sea ice and the change of mixed layer depth (MLD) also contribute to the spatial and seasonal variations of NIKE.

Summary: This study investigates the potential impacts of reduced inflow and increased sediment concentrations on excess sediment deposition in gravity sewers through experiments and modeling. The results show that implementing sustainable water practices can significantly affect the quantity of sediment deposited in gravity sewers, but a moderate decrease in peak flow velocity is unlikely to result in a net increase of sediment deposition in existing sewer mains with reasonable slope and flow velocities. Future work could focus on confirming these findings through case studies or long-term pilot studies.

Summary: This study investigated the use of digestate as a nutrient source and its interactions with biochar when applied to potting mix targeted for localised urban use. The results showed that plant biomass and shoot N concentration increased with digestate addition in a typical nutrient dose-response curve. The application of biochar decreased soil mineral N content and altered the structure of the rhizosphere bacterial community. These findings contribute to optimizing the process of converting urban waste into organic fertilizers, promoting environmental protection and plant growth.
