Summary: The Yellow Sea has experienced overfishing, leading to changes in the community structure. The development of a multi-species OSMOSE model allowed researchers to simulate different fishing scenarios and observe the impact of fishing pressure on the Yellow Sea ecosystem. Long-term fishing pressure resulted in a decline in biomass, body sizes, and longevity of modeled species. The study suggests that reducing fishing pressure can help restore the ecosystem and increase the proportion of elder and larger individuals.

Summary: This study proposes a framework to mitigate the impacts of hydropower generation on fish biodiversity in large reservoirs, considering water quality and hydraulic factors. Data-driven models were used to simulate effective parameters, and a multivariate linear regression model was used to estimate the fish biodiversity index. The simulators were applied to optimize hydropower plant operation under different hydrological conditions, aiming to minimize fish biodiversity loss and loss of hydropower generation. The results showed that the simulators reliably modeled physical flow, water quality parameters, and fish biodiversity index, and the optimization model effectively reduced impacts on fish biodiversity. However, high computational complexities may limit the model's applicability.

Summary: This study highlights the importance of understanding the responses of toothfish and other species to fishing activities in order to promote sustainable use of natural resources. The authors developed a model to simulate the food web dynamics in the Cooperation Sea and evaluate the impact of toothfish fishery. The results show that overexploitation of toothfish stock may lead to trophic cascades and impact other species in the ecosystem. Precautionary and ecosystem-based management measures are necessary to protect toothfish fishery and ensure the sustainability of the ecosystem.

Summary: The complexities of ecosystem-based management require stepwise approaches involving stakeholders to scope key processes, pressures, and impacts. Fuzzy Cognitive Mapping (FCM) presents a qualitative method with a lower skill and data threshold than quantitative models to evaluate marine ecosystems under various impacts. The results of applying FCM models for subregions of the North Sea show the potential of combining FCM and quantitative modelling approaches in integrated ecosystem assessments (IEAs) and future ecosystem-based management advice.

Summary: The inclusion of ecosystem information into fish stock assessments and management advice is important for ecosystem-based fisheries management. This study provides an overview of how ecosystem trends and variability are incorporated into ICES fishing opportunities advice in the Northeast Atlantic. Around 50% of stock assessments considered ecosystem information, while the majority of management strategy evaluations did so in some way. The inclusion of ecosystem information was influenced by stock and fisheries characteristics, with pelagic species and high catch stocks having higher instances of incorporation.

Summary: The spatial extent of protected areas (PAs) is a highly debated issue in the decision-making process of the post-2020 Global Biodiversity Framework. Despite efforts to protect land and oceans, biodiversity loss remains a challenge. While expanding PAs to 30% may have benefits for biodiversity and climate, it is crucial to consider the effectiveness of PAs and potential trade-offs with food production.

Summary: Balanced harvest (BH) is a possible strategy for ecosystem-based fisheries management, proposing moderate fishing mortality rates across all species or sizes to ensure sustainability. In this study, an OSMOSE ecosystem model was used to investigate the potential occurrences and advantages of BH in the highly exploited Yellow Sea in China. The results showed that the occurrences of BH depended on fishing pressure and targeted functional groups, and size-level BH was significantly correlated with biomass and yield for most species. Adjusting fishing pressure for certain functional groups could potentially achieve the benefits of BH in over-exploited ecosystems.

Summary: Earth's biodiversity and human societies are threatened by pollution, overconsumption of resources, urbanization, demographic changes, inequalities, and habitat loss, which are worsened by climate change. This review examines the connection between climate, biodiversity, and society, and proposes a roadmap for sustainability. The roadmap includes limiting global warming to 1.5 degrees Celsius and preserving and restoring ecosystems on a significant portion of land and water. It emphasizes the need for interconnected protected areas and shared spaces to enhance biodiversity, and the ability of people and nature to adapt to and mitigate climate change. It calls for bold policy interventions and interconnected systems at all levels to promote human, ecosystem, and planetary health for a livable future.

Summary: This study uses Bayesian Additive Regression Trees to model the effects of climate change on the habitat suitability of marine fish species in the northeast Atlantic shelf seas. Predicted effects include decreases in species richness for lower trophic levels (planktivores) and increases for higher trophic levels (piscivores). Changing spatial patterns in predator-prey mass ratios and fish species size composition are also predicted. These changes could have significant impacts on ecosystem structure and functioning.

Summary: In the Mediterranean, discarding commercial species smaller than the minimum conservation reference size (MCRS) is a common practice. However, this study shows that other factors, such as market demand and fishing restrictions, have a greater impact on the discarding process. Using spatial analysis and Bayesian spatial models, the researchers found that species with low market value were often discarded independent of their size. Management strategies specific to different areas and species are necessary to reduce discards.

Summary: The theoretical consequences of slip effects in a complex stenosed region are analyzed in this study. Hybrid nanofluid features prepared with copper and copper oxide nanoparticles are incorporated into the flow of blood in a stenosed region. An electric field is also applied in the axial direction to intensify the flow. Closed-form solutions for the proposed paradigm are obtained for cases of mild stenosis. Special focus is given to parameters such as Electro-osmotic, velocity slip, and Helmholtz-Smoluchowski. The heat transfer, hemodynamic velocity, wall shear stress, and resistance impedance for the flow are accurately determined. The study plots the various parameters influencing the physical characteristics of flow and discusses their effects in detail. The present model has potential applications in medical pumps for drug delivery systems.

Summary: Multiple stressors can have unexpected impacts on ecological systems, but our ability to evaluate these impacts is limited due to a lack of information about historic trophic interactions and ecosystem dynamics. A study was conducted on the Saronikos Gulf to model the ecosystem and simulate the effects of sea surface temperature increase, primary productivity shifts, and fishing effort release. It was found that historical fishing and environmental factors have influenced ecosystem dynamics, and future scenarios showed that increasing temperature had a detrimental impact while fishing reductions benefited top predators.

Summary: This study analyzed the impact of climate change on the Northwest Atlantic Ocean and evaluated its consequences for marine protected areas in Atlantic Canada. The study identified climate change hotspots and refugia and found that currently, there is no overlap between existing marine conservation areas and climate refugia. The majority of established marine protected areas and other conservation measures are located within climate hotspots. These findings provide important context for long-term marine conservation planning in Canada and the Northwest Atlantic region.
