This study presents a novel framework that integrates the Future Land Use Simulation (FLUS) and Integrated Valuation and Trade-offs of ESs (InVEST) model, with the Multi-Model Ensemble (MME) derived from NEX-GDDP-CMIP6. This approach, the first of its kind in East Africa (EA), examined projected changes in water yield (WY), carbon storage (CS), and habitat quality (HQ) were assessed under SSP126, SSP245, and SSP585 scenarios for the 2041-2060 (2050s) and 2081-2100 (2090s) compared to the historical period (2000-2020). The findings revealed regional variability in precipitation, with an increase of 0.2 in certain areas during the 2050s and a projected temperature rise of 0.7, with significant warming expected by 2090 under the SSP585. The FLUS model exhibited high accuracy, with an overall accuracy of 0.95 and a Kappa coefficient of 0.93. Projections indicate a substantial reduction in barren land (35.7%) and forestland (24.63%), alongside an increase in cropland (24.92%) and urban areas (106.71%) by 2090. All scenarios showed reductions in ESs, with WY decreasing up to 31.36% under SSP126 and CS projected to decline by 6.38% under SSP585 by 2050. Whereas HQ is expected to fall by 5.37% under SSP585 by 2090. These highlight the growing pressures of climate and land use change on ES, offering critical insights for reconciling environmental preservation with socioeconomic development in the region.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":"504 ","pages":"Article 111092"},"PeriodicalIF":2.6,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683000","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}

The interdisciplinary nature of this research complicates tracking advancements, and no comprehensive overview exists. This Systematic Literature Review (SLR), using the PRISMA method, addresses this gap by analysing studies on dynamic modelling of flora and fauna in digital twins and 3D city models. It covers descriptive metrics and qualitative aspects, identifying key research fields, directions, users, and developers. Additionally, this SLR details on digital twin data, modelling techniques, actuators, user experience with human-computer interaction, and ethical considerations. The findings highlight that the digital twin concept is being increasingly applied to the dynamical modelling of flora and fauna. Moreover, the broad relevance of this research is demonstrated across various fields including ecology, forestry, urban studies, and agriculture, where diverse methods and technologies are used, though progress remains uneven. Currently, precision agriculture is leading the way in automated, bidirectional synchronisation between digital twins and their physical counterparts. Complementing traditional modelling techniques with AI and machine learning where appropriate, expands modelling capabilities. Meanwhile, multimodal interfaces enhance the immersive user experience. Despite these advances, challenges persist in data availability, foundational knowledge, complex interaction modelling, standardisation and transferability, underscoring the need for continued research.

In contrast to saltmarshes of temperate latitudes, these only occupy the uppermost niche of the intertidal zone, and are characterised by periods of severe drought and hypersalinity in the upper soil during dry seasons. Like mangroves, they show pronounced species zonation patterns along elevation gradients. The primary driver behind these soil water patterns is the variation in tidal flooding frequency, especially notable in the upper tidal zone. Precipitation is the second main source of water, and evapotranspiration and plant transpiration are further factors shaping soil water dynamics and driving plant growth. To describe and comprehend the soil water processes and their dynamics in tropical saltmarshes, we introduce the hydrological model SALTFRED. This model aims to mechanistically predict soil water salinity and root zone soil moisture, elucidating the intricate differentiation of drought and salt stress within the saltmarsh. The model explicitly describes processes of infiltration, seepage and evapotranspiration, along with their influence on the salinity of the soil water. We demonstrate its suitability with an application to a specific study site on the Bragança Peninsula (Pará, Brazil). Utilising complete time series of tidal data and precipitation (for the year 2015), we predict drought and salt stress and compare simulated levels of stress with tolerance levels of the dominant vegetation types and saltmarsh species. Extreme salt and drought stress are defined as salt concentrations of <em>90</em> parts per thousand (ppt) and plant available water of <em>0.5</em> vol<em>%</em> (0.005 cm³ water per cm³ of soil), respectively. The results suggest that mangrove vegetation thrives where these extreme stress conditions are persistently not reached due to regular flooding by the tides. In the saltmarsh, as elevation increases and the frequency of spring tide flooding decreases, longer periods without water infiltration occur. As a result, the duration of salt stress events increases. In the higher parts of the saltmarsh, additional drought stress is predicted. Our results confirm a robust correlation between simulated levels of seasonally varying drought and salt stress and tolerance levels of the dominant saltmarsh species <em>Rhynchospora riparia, Fimbristylis cymosa</em>, and <em>Sporobolus virgincus</em> at the study site.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":"504 ","pages":"Article 111089"},"PeriodicalIF":2.6,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
