At the other end of the spectrum, 12 countries consistently ranked low in sustainability performance throughout the studied timeframe.

Various policies are suggested on the solution of the problem; however, to the best of our knowledge, there is no study to determine the socio-economic effects of such policies in terms of sustainability through a mathematical method. In this study, a simulation model based on system dynamics to analyze the effects of the mucilage explosion seen in the Sea of Marmara on fisheries, tourism and maritime transport is proposed. The proposed model enables the decision makers to examine the complex relationships between factors leading to mucilage, the level of the explosion, and fisheries, tourism and maritime transportation sectors. The simulation results display critical levels of mucilage if no precautions are taken. The model also allows examining policies aimed at preventing mucilage risk and eliminating the negative impacts on the above-mentioned three sectors considering environmental sustainability. Out of the four different policies, it is displayed that policies focusing on decreasing total nitrogen and total phosphorus loads in the sea seem to be the most appropriate ones for the sustainable solution of the mucilage problem.

We present SyrFitSources, an agent-based model (ABM) for investigating the effect of land use on the population dynamics of the aphidophagous hoverfly <em>Episyrphus balteatus</em> on landscape scale in Central Europe. SyrFitSources considers 1) the life cycle of <em>E. balteatus</em>, 2) the resources of the larvae, i.e., aphids, 3) the resources of the imagines, i.e., pollen and nectar, and 4) the effect of insecticides on aphids and on syrphid larvae. For model testing, analysis, calibration, and evaluation, we used pattern-oriented modeling to compare the ABM results with observed numbers of active <em>E. balteatus</em> in 13 landscapes in Southern Germany in 2011. SyrFitSources reproduced these activity patterns. In 14 sensitivity experiments, we investigated the effects of stage-dependent mortality, migration, feeding, and reproduction on imaginal density. The effects were generally small, where variation of migration-related parameters had the largest effect on imaginal density. An additional resource-reduction scenario of aphids and floral resources suggests that the reduction of aphids has a stronger effect on the density of <em>E. balteatus</em> than that of floral resources. Two scenarios on the effect of insecticides on hoverfly larvae indicate that hoverfly populations are more strongly influenced by the insecticide-related reduction of aphid populations than by the direct effect of insecticides on hoverfly larvae. We conclude that SyrFitSources is a valuable tool for applied sciences, e.g., to assess ecological effectiveness of biodiversity measures in agricultural landscapes.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":"507 ","pages":"Article 111098"},"PeriodicalIF":2.6,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate projections for the end of the century were based on three bias-adjusted EURO<img>CORDEX simulations - MOHC<img>HadGEM2-ES/RACMO22E, MOHC<img>HadGEM2-ES/CCLM4–8–17, and MPI-MPI-ESM-LR/REMO2009 - all under the RCP 8.5 high-emission scenario.

The results indicate that heatwave-induced temperature increases lead to significantly reduced dissolved oxygen levels. The most significant increase in reservoir water temperature was 9.2 °C (μ = 7.2; σ = 1.2) from July to August. Meanwhile, dissolved oxygen levels decreased by 2.1 mg/L (μ = -1.4; σ = 0.5) during the same period, thereby restricting the areas available for fish growth.

To address these barriers, we identify key areas for future research, namely optimizing data collection, using transfer learning and data augmentation, refining model transparency through explainable AI (XAI) and ethical considerations, and integrating causal inference into AI models. We conclude that AI algorithms hold great promise for delivering more accurate, scalable, and timely data, advancing real-time monitoring and near-instantaneous predictions – e.g., seasonal forecasting – for more dynamic responses to environmental changes.

Recognizing the increasing importance of coupled systems in environmental management, the methodology is illustrated by a case study of a managed fishpond, partially covered by reed vegetation, and surrounded by reed beds. The unified elements of Programmable Process Structures (PPS) are used to analyze the underlying processes (physical, chemical, biological, ecological, technological, and managerial) and to determine the effects of management interventions on the environmental interactions of the fishpond agroecosystem. Simplified sub-process models have been implemented to calculate the dynamic environmental interactions of the example system studied. The sub-models exploit the approximate stoichiometries and causal relationships behind the environmental interactions with a transparent insight into the structured functionalities of the complex system. These features provide holistic model-based simulations from which the impacts of different management scenarios can be assessed. It is also discussed how the calculated quantitative environmental interactions can be used for a more rigorous assessment of ecosystem services (ES) and dis-services (EDS). It is concluded that many categories of ES (such as provisioning and regulatory services) can be derived directly from the quantitative environmental interactions. Other categories, such as habitat maintenance for biodiversity and cultural services, can be derived by combining the simulated quantitative data with expert-defined qualitative rules.
