Summary: Nutrient input drives macroalgal blooms and increases in photosynthetic activity in coastal ecosystems. Under eutrophic conditions, the photosynthetic activity of Ulva lactuca can control pH variability, while seasonal pH variations are related to environmental features such as seawater temperature.

Summary: Global change has complex effects on plant productivity in coastal ecosystems, with elevated salinity negatively impacting productivity across all environments and nitrogen enrichment positively affecting productivity. Herbivory has the greatest negative impact in saline habitats, but this trend may reverse with nitrogen enrichment, leading to maximum losses occurring in brackish habitats. These findings suggest that multiple stressors can have contrasting outcomes and trophic interactions may shift as coastal ecosystems continue to experience nutrient enrichment and sea level rise.

Summary: The excess input of nutrients has destabilized coastal ecosystems and led to dystrophic crises. Mar Menor lagoon has suffered from these events after 30 years of nutrient input. Phosphorus and nitrogen alternate as limiting nutrients for phytoplankton, with phosphorus mainly related to vacation periods and nitrogen related to high nitrates concentration. Summer is prone to periods of hypoxia when the N/P ratio decreases and temperature rises. The loss of control over phytoplankton due to the decline in jellyfish abundance has affected the ecological balance. Management actions should focus on addressing water and nutrient input sources.

Summary: We conducted a field experiment in a salt marsh in Virginia, USA to investigate the effects of grazing intensity and nutrient availability on smooth cordgrass (Spartina alterniflora). We found that both grazing and fertilization had significant impacts on various ecological traits, which can influence ecosystem functions.

Summary: The study examined the impact of changes in herbivore assemblages on top-down and bottom-up processes in coral reef ecosystems. Large excavating parrotfishes and other herbivores play crucial roles in coral health and nutrient recycling in coral-dominated reefs, while detritivorous fishes contribute to algal dominance in algal-dominated reefs. Identifying the unique roles of consumers in maintaining and reinforcing ecosystem states is essential for predicting the effects of shifts in consumer assemblages.

Summary: The feasibility of introducing macroalgae Ulva lactuca into the culture of Litopenaeus vannamei in a biofloc system was investigated. The results showed that the growth of macroalgae was not significantly affected by biofloc or von Stosch culture medium. In the integrated culture, a density of 1 g L-1 showed better nutrient absorption. Shrimp performance was not affected by macroalgae cultivation.

Summary: Pollution by heavy metals, originating from manufacturing, fertilizers, mining, pesticides, transport, and wastewater discharge, is a serious global issue. This study evaluated the presence of macroelements (N and P) and heavy metals (Cr, Ni, Cd, Fe, Zn, Pb, Cu, and Mn) in the green seaweed Ulva lactuca from the Marchica lagoon in NE-Morocco. Results showed that Ulva had a strong affinity for Fe and Mn, with the highest bioconcentration factors recorded for Mn, Fe, and Pb. The health risk assessment indicated no hazards associated with the consumption of Ulva lactuca.

Summary: Land-source inputs have led to the deterioration of water quality, eutrophication, and algae blooms in Tieshan Bay coastal water. However, there is limited understanding of nutrient patterns, stoichiometry, and eutrophication assessment in this area. A study conducted in 2021 revealed high concentrations of dissolved inorganic nitrogen, dissolved inorganic phosphorus, and chemical oxygen demand in Tieshan Bay, with a significant contribution from COD to eutrophication. Organic pollution was observed in certain areas, and nutrient concentrations showed a significant relationship with salinity. Land-based source management is crucial to achieve seawater quality targets and mitigate eutrophication in the region.

Summary: The Anthropocene epoch has seen a decline in oxygen concentrations and expansion of oxygen-depleted environments due to human activities. Case studies highlight the complexity of factors influencing oxygen concentrations, requiring system-specific models for understanding and predicting future changes.

Summary: Restoration of coastal wetlands often focuses on relieving abiotic stress and preventing disturbances, while overlooking the impact of herbivorous grazers on plant recovery. Field experiments have shown that crab grazing, rather than abiotic stress, is the main obstacle to the recovery of native foundation plant species such as Scirpus maritimus. Control measures for crab grazing are essential for successful restoration, even in areas with optimal abiotic conditions.

Summary: This study explored the effects of climatic variability on water quality in various water systems in the Netherlands, showing that water quality is impacted by global climate change, changes in Atlantic ocean circulation patterns, continental precipitation, river discharge fluctuations, and local climatic fluctuations. The fluctuations induced by climatic variability give a preview for the potential effects of climate change on water quality.

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: Ulva was negatively affected by decreased salinity, but the effects were mitigated by adding nutrients, allowing it to maintain bloom potential under reduced salinities. Increased nutrients altered nitrogen and carbon uptake pathways in Ulva, enhancing its growth potential.

Summary: This study quantified the surface layer turbulent and fine structure under landfast ice in Antarctica, revealing that landfast ice significantly reduces turbulence levels and affects energy dissipation. The regional effects of landfast ice and the contributions of wind and tides to the turbulent kinetic energy budget in the surface ocean exhibit significant variations.

Summary: This study investigates the seasonal variation of nutrients, eutrophication patterns, and Chlorophyll a (Chl-a) response in the coastal waters adjacent to Guangdong Province. The results show significant differences in Chl-a, dissolved inorganic nitrogen (DIN), and phosphorus (DIP) concentrations among seasons. It is necessary to strengthen integrated land and sea management to mitigate eutrophication and harmful algal blooms.
