Summary: This study explores the relationship between the element composition of seabed rocks and the abundance of epilithon diatoms and cyanobacteria. The results show that the elemental composition does not significantly affect the total abundance of the communities, but there are strong correlations with certain non-dominant species.

Summary: Recent studies have shown the usefulness of diatom eDNA metabarcoding for assessing river and stream ecological quality. However, differences in taxonomic markers and data analysis methods hinder result comparison. This study compared two taxonomic markers and three analytical approaches and found that taxonomy-free methods were more correlated with morphological index values, with rbcL marker showing higher correlations than 18S marker.

Summary: “The study reveals that sediment biofilms in mangrove ecosystems are mainly composed of diatoms, bacteria, and EPS. The differences in nutrient accumulation and composition of diatoms between Futian and Qi'ao are influenced by the salinity-driven by tide currents. The seasonal variations, such as between late spring and early summer, also affect the abundance of diatoms and EPS fractions in sediment biofilms.”

Summary: Through monthly samplings and satellite color images from 2002 to 2019, researchers combined data to determine that the ecosystem disruptive algal bloom (EDAB) affecting the Mar Menor coastal lagoon began in 2014 with significant changes attributed to increasing abundance of Synechococcus. Furthermore, changes in diatom and dinoflagellate abundances from 2016 to 2019 were linked to floods, indicating that EDAB has substantially altered the homeostatic capacity of the lagoon.

Summary: This study compared environmental conditions and phytoplankton biomass/composition in three Texas estuaries with different freshwater inflow regimes to understand the impact of freshwater inflow on phytoplankton communities. The results showed that despite differences in freshwater inflow, salinity, and nutrient regimes, differences in phytoplankton community composition were relatively small, indicating the influence of other factors.

Summary: Forty years ago, the estuary of the Black Sea was transformed into a freshwater reservoir through the Danube-Sasyk Canal. The inflow of the Danube water into the Sasyk plays a crucial role in the water balance and affects the aquatic environment. The changes in algal communities during the transformation stages were studied, and the influence of salinity on their composition was observed. The species list of algae and cyanobacteria in the Sasyk was presented for the first time, and the importance of the Danube River in maintaining the ecological status of the reservoir was emphasized.

Summary: This study investigates the key factors shaping sediment biofilms in contaminated mangrove sediments. It reveals that the pennate diatom Navicula plays a crucial role in balancing the abundance of other diatoms and producing bound-polysaccharides. High nutrient concentrations and contaminants affect the composition and structure of biofilms.

Summary: This paper explores the impacts of 19 years of restoration managements on botanical diversity in upland temperate grassland. The type of defoliation was found to be the key driver influencing plant species diversity, with postponing the first defoliation to the middle of the growing season being the most effective restoration management option. Continuous low-density sheep grazing was not recommended as a means of long-term maintenance or restoration management of European temperate grasslands.

Summary: Glaciers provide essential runoff for mountain streams, maintaining unique habitats and supporting diverse flora and fauna. As glaciers retreat, significant changes are observed in mountain ecosystems, impacting stream conditions and diatom communities.

Summary: Sea-bottom plowing is a method of oxidizing sediment by stirring the bottom using a trawl fishing tool. It has been found to increase the primary productivity of water column by promoting the growth of diatom cells. Field sampling showed abundant diatom resting stage cells in the sediment, which emerged and grew under sunny weather conditions. Actual trials of sea-bottom plowing for 4 years demonstrated an increase in dissolved inorganic nutrients and chlorophyll a concentration, with diatoms contributing significantly to the latter. Turbid water caused by plowing initially led to a decrease in estimated primary productivity but was followed by a significant increase after a few days.

Summary: Data from multiple research cruises in the Alboran Sea were used to study seasonal variability of phytoplankton light absorption properties. Surface temperature and salinity were found to be key factors affecting absorption properties. Seasonal and regional parameterizations based on these findings showed promise for refining bio-optical models of primary production.

Summary: This study compared the effects of different fertilizers on ammonia volatilization and greenhouse gas emissions in purple soil, and found that vermicompost prepared with cow dung can reduce ammonia volatilization and greenhouse gas emissions. It also has positive effects on crop yield and soil nutrient cycling during the wheat-maize rotation.

Summary: The increased anthropogenic nitrogen emissions from northeast Asian countries have led to significant changes in the nitrogen concentrations in the coastal waters of the Yellow and East China seas and around Korea, altering the nutrient ratios and leading to shifts from N deficiency to P deficiency. The dynamics of the nitrogen to phosphate ratio in different sea areas are influenced by atmospheric nitrogen deposition, riverine nutrient inputs, and changes in ocean currents.

Summary: The silicon isotope composition of silicic acid in the deep Arctic Ocean is anomalously heavy compared to other ocean basins. The study shows that the isotope values reflect local processes such as drift waters influence and benthic inputs, as well as overall inflow-outflow similarity. Biological productivity and opal burial play a major role in removing light isotopes entering the Arctic Ocean from rivers.
