Harmful algae at the complex nexus of eutrophication and climate change

TL;DR: In this article , the authors present case studies of HABs in five different locations as examples of their effects on different sectors of the blue economy, with a particular focus on the application of science and technology in their management and mitigation.

TL;DR: Eutrophication in Romanian lakes and reservoirs is a serious environmental issue that requires immediate action. The lack of monitoring and assessment data on eutrophic lakes and reservoirs in Romania is alarming. Only a small fraction of lakes and reservoirs have been monitored, and the quality objectives are not being met. There is a need for supplementary measures to better understand and mitigate eutrophication in Romania.

TL;DR: A one-dimensional ecosystem model integrating sediment and ecosystem components was developed to analyze oxygen depletion, nutrient dynamics, and sediment organic matter's influence on oxygen concentrations in enclosed water bodies, such as Lake Biwa, Japan's largest lake.

TL;DR: Short-term and long-term exposure to combined elevated temperature and CO2 leads to differential growth, toxicity, and fatty acid profiles in Karlodinium veneficum.

TL;DR: This work has developed a quantitative theory for how metabolic rate varies with body size and temperature, and predicts how metabolic theory predicts how this rate controls ecological processes at all levels of organization from individuals to the biosphere.

TL;DR: The first worldwide synthesis to jointly consider human and biodiversity perspectives on water security using a spatial framework that quantifies multiple stressors and accounts for downstream impacts is presented.

TL;DR: Optimizing the need for a key human resource while minimizing its negative consequences requires an integrated interdisciplinary approach and the development of strategies to decrease nitrogen-containing waste.

TL;DR: In this article, a review of available scientific evidence shows that human alterations of the nitrogen cycle have approximately doubled the rate of nitrogen input into the terrestrial nitrogen cycle, with these rates still increasing; increased concentrations of the potent greenhouse gas N 2O globally, and increased concentration of other oxides of nitrogen that drive the formation of photochemical smog over large regions of Earth.
