Abstract:In this study, the effects of sea ice and wind speed on the timing and composition of phytoplankton spring bloom in the central and southern Baltic Sea are investigated by a hydrodynamic–biogeochemical model and observational data. The modelling experiment compared the results of a reference run in the presence of sea ice with those of a run in the absence of sea ice, which confirmed that ecological conditions differed significantly for both the scenarios. It has been found that diatoms dominate the phytoplank… Show more
Eutrophication of water bodies and deterioration of water quality is an emerging environmental crisis. The root causes, pathways and consequences of eutrophication are multidirectional and provide a huge scope of riskanalysis and risk-assessment in the domain of remediation studies. However, a deep insight on restoration studies shows a global transitional trend of evolution of traditional restoration methods to advanced innovative techniques with pioneering development in the eld of science and technology. This study introduces a novel approach of considering ecohydrological assessment of eutrophication emphasizing classical biomanipulation practices and their evolution into innovative methods coined as 'eco-bioengineering' method. The main objective of this study is to critically analyse and recognize the research gaps in classical biomanipulations and appreciate the reproducibility and e cacy of eco-bioengineering methods at micro-and macrolevel aquatic ecosystems. Comprehensive literature review was conducted in o ine and online planforms, and our survey revealed continuation of a historical trend in classical biomanipulation practices (75.36%) and an ascending drift in eco-bioengineering research (24.64%) in the immediate decade (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020). At a global scale, recent biomanipulation research is skewedly distributed in Europe (43.48%), East Asia (34.78%), North America (8.70%), South America (2.90%), South Africa (4.35%), Oceania (1.45%), Middle East (1.45%) and non-speci c regions (2.90%). Finally, this study revealed the comprehensiveness of eco-bioengineering methods and their strong ecological resilience to recurrence of eutrophication and uctuating environmental ows in the future. Therefore, this study reinforces eco-bioengineering methods a cost-effective green technologies that will sustainable solutions for restoration of eutrophic waters at a global scale.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
