This integrated approach will improve our ability to predict and manage the impacts of nutrient enrichment and other stressors on coastal ecosystems. 7 Conclusion Marine ecosystems are undergoing significant changes due to both natural and anthropogenic factors. A meta-analysis of 110 marine experiments revealed that species richness generally enhances ecosystem function, although the effect varies depending on the specific ecosystem process being measured. Ecological niche models (ENMs) and species distribution models (SDMs) have become crucial tools for understanding species distribution patterns and their underlying processes, with significant applications in conservation and climate change impact assessments. Biogeochemical models have been instrumental in simulating key ecosystem components such as chlorophyll-a, nutrients, and carbon cycles across various marine environments, although they still face limitations and require further refinement. The integration of biogeochemical and ecological models with ocean circulation models has shown promise in monitoring and managing ecosystem health, despite challenges related to sparse biogeochemical observation streams. Additionally, the role of adaptive evolution in marine ecosystems is increasingly recognized as a critical factor that can influence the accuracy of model projections Future research should focus on expanding biogeochemical and ecological observation systems to improve the accuracy and applicability of predictive models. Incorporating adaptive evolution into marine ecosystem models is essential for better understanding long-term ecosystem responses to environmental changes. There is also a need to integrate omics data with earth system science to enhance our quantitative understanding of marine microbial roles in biogeochemical cycles. The use of advanced data assimilation techniques, such as those involving BGC-Argo measurements and satellite-derived phytoplankton functional type data, can significantly improve model predictability and reduce uncertainty. Moreover, exploring multiple post-extinction compensatory scenarios can provide more realistic projections of ecosystem futures, aiding in the development of effective management strategies. Integrating biogeochemical and ecological models with conservation efforts is crucial for developing effective strategies to mitigate the impacts of climate change and other anthropogenic stressors on marine ecosystems. Predictive models can guide conservation policies by providing insights into the potential outcomes of different management scenarios. The use of ENMs and SDMs can help identify critical habitats and species at risk, informing targeted conservation actions. Additionally, understanding the functional responses of ecosystems to biodiversity loss and community reorganization can improve the reliability of ecological projections and support adaptive management practices. By combining observational data with advanced modeling techniques, we can enhance our ability to protect and sustain marine biodiversity and ecosystem functions in the face of ongoing environmental changes.
