Ocean acidification and warming significantly affect coastal eutrophication and organic pollution: A case study in the Bohai Sea

Marine Pollution Bulletin, Journal Year: 2022, Volume and Issue: 186, P. 114380 - 114380

Published: Nov. 29, 2022

Most coastal ecosystems are faced with novel challenges associated human activities and climate change such as ocean acidification, warming, eutrophication, organic pollution. However, data on the independent or combined effects of acidification warming eutrophication pollution at present relatively limited. Here, we applied generalized additive models (GAMs) to explore dynamics in response future Bohai Sea. The GAMs reflected fact that alone favors pollution, while inhibits these two variables. Differently, interactions between may further exacerbate but mitigate progress eutrophication. These different responses be attributed algae growth microbial respiration, well some physical processes stratification.

Driving Factors and Variability of Cyanobacterial Blooms in Qionghai Lake, Yunnan–Guizhou Plateau, China

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 169 - 169

Published: Jan. 10, 2025

Qionghai Lake is an important freshwater source in the Yunnan–Guizhou Plateau. However, cyanobacterial blooms have been observed recently Lake, but their formation mechanism and control management are not well understood. Herein, phytoplankton, zooplankton, eutrophication, nutrients, biochemical indices were measured from May 2022 to April 2023. The results showed that predominated Anabaena sp. with a density of 1.11 × 107–18.87 107 cells/L. started northwestern area November then expanded entire lake until it peaked subsided February Protozoa dominated zooplankton while having no significant relationship Lake. trophic level index chlorophyll similar spatiotemporal trends density, water quality northwest was worse than other parts. Total nitrogen (TN) total phosphorus (TP) 0.41–0.54 0.021–0.045 mg/L TN TP positively correlated most environmental factor affecting bloom These findings might provide essential information for improving remediation

Effect of heavy metal copper on the physiological characteristics of Ulva lactuca at different temperatures

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 21, 2025

Copper (Cu) is an essential element for macroalgae and has been extensively studied, but the interactive effects of temperature Cu on these organisms remain less understood. In this study, we measured photosynthetic characteristics Ulva lactuca exposed to varying concentrations different temperatures (10 °C, 15 20 °C). The results indicated that at same temperature, as concentration increased, relative growth rate U. showed a decreasing trend. Under three temperatures, chlorophyll content algae significantly decreased with increase in concentration. conditions, rises, RGR gradually increases. case low (LCu), net °C increased by 103.72% 104.97%, respectively, compared 10 °C. high (HCu), 192.18% 245.67%, pigment similar These under inhibited algae, while treatment suitable could alleviate toxic algae.

Phytoplankton and Zooplankton Community Dynamics in an Alpine Reservoir: Environmental Drivers and Ecological Implications in Daqing Reservoir, China

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1202 - 1202

Published: April 17, 2025

To elucidate the structural characteristics and environmental drivers of plankton communities in alpine reservoirs, we examined phytoplankton zooplankton Daqing Reservoir (China) across 13 sampling sites. Redundancy analysis (RDA) Pearson correlation were employed to explore relationships between density factors, as well diversity indices conditions. Key findings include: (1) A total 80 species identified, with Chlorophyta (37 species) dominant group, while 52 primarily represented by Rotifera. (2) Phytoplankton (Shannon: 3.07–4.21) suggested oligotrophic conditions, whereas 1.40–3.08) indicated meso- states. (3) RDA revealed that distribution was influenced chemical oxygen demand phosphorus, related ammonia nitrogen. These results highlight importance targeted nutrient management strategies protect water quality reservoirs.
