This coupled model, combined with high-resolution TerraClimate precipitation data, was used to evaluate the WCF in Zhang-Cheng (Zhangjiakou and Chengde) area.

Vegetation impacts were complex and varied across ecosystems and years; (5) Sensitivity analysis indicated exponential decline in parameter influence on WCD, with grasslands being the most sensitive. The InVEST-GA framework significantly improves accuracy and offers a robust foundation for eco-hydrological studies and ecosystem service evaluation in the Zhang-Cheng area.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"179 ","pages":"Article 114237"},"PeriodicalIF":7.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145155195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Here, we developed a space-for-time substitution approach that used seven separate net ecosystem productivity (NEP) datasets and one forest age dataset to analyze in detail the age-related changes in NEP of intact boreal forests. Our analysis of NEP dynamics in intact boreal forests uncovered two key patterns. First, old forests exhibited significantly lower NEP compared to younger forests, highlighting an age-related decline in carbon sequestration capacity. Second, temporal trends (2001–2015) revealed increasing NEP with forest age across most datasets; however, this positive trend was markedly weaker in old forests. This widespread positive trend paralleled weak, non-significant increases in air temperature and precipitation across most age classes, suggesting that concurrent climate variability may have contributed to the observed increases in NEP and partly masked age-related declines. Collectively, these findings demonstrate that both the magnitude of NEP and its rate of increase declined with forest aging. Mechanistic investigations elucidated that the observed NEP reduction in aging forests primarily stemmed from a disproportionate decline in forest productivity, which decreased more rapidly than respiratory losses, thereby driving the overall decrease in carbon sequestration capacity. We provided new evidence for previous hypotheses based on spatially separated sites using global-scale gridded NEP datasets. Our results indicate that intact boreal forests progressively lose carbon sequestration capacity as they age, and may become net carbon sources unless climate-driven gains in productivity surpass respiratory losses.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"179 ","pages":"Article 114231"},"PeriodicalIF":7.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145155194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 Yangtze River Basin (YRB), as the world’s third longest river and a core inland segment of the East Asian-Australasian Flyway, exemplifies a highly heterogeneous socio-ecological system where rapid, uneven urbanization intersects steep climatic and hydrological gradients. Drawing on 26,429 citizen‑science waterbird observation reports (2007–2021), we found a spatiotemporal divergence in environmental factors affecting waterbird diversity across urban versus non-urban areas and between breeding and wintering seasons. Specifically, waterbird diversity is driven mainly by disturbance and fine-scale site conditions in urban areas but by a broader environmental suite in non‑urban areas. We also found that currently designated protected areas (PAs) only covered most of the key habitats in non‑urban areas during breeding season. Thus, we proposed a spatially stratified framework to identify key habitats that distinguishes urban and non‑urban areas for waterbirds. Connectivity modeling based on these key habitats identified corridors bridging urban and non‑urban wetland complexes and highlighted unprotected linkage bottlenecks. Integrating the revealed spatial and seasonal driver contrasts with diversity hotspots, focal species distributions, and connectivity outputs, we propose a stratified multi‑indicator framework that operationalizes waterbird diversity as a habitat network design tool to guide targeted protected areas expansion and ecological corridor planning in large human‑modified river basins.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"179 ","pages":"Article 114230"},"PeriodicalIF":7.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Biochar enhances soil structure and nutrient availability and, therefore, can play a crucial role in restoring degraded grassland. However, the long-term effects of biochar addition on both active and passive restoration of desertified grasslands remain unclear. This aim of this study was to fill this gap by determining how biochar influences organic carbon mineralization and priming effects in grasslands undergoing more than a decade of active or passive restoration. The results demonstrated that, compared to degraded grassland, biochar application under active restoration increased soil CO₂ emissions significantly. Positive priming effects were observed in both the topsoil (120.5–297.0 %) and subsoil (157.2–287.3 %). Conversely, under passive restoration, priming effects were positive in the topsoil (34.7–80.9 %) but negative in the subsoil (−67.1% to −47.7 %). In passive restoration, phospholipid fatty acids (PLFA) were the primary drivers of priming effects, while in active restoration, soil pH was the primary driver. This study bridges the fields of restoration and soil ecology by evaluating the effects of biochar on organic carbon mineralization and priming effects in degraded grasslands. The findings highlight the importance of understanding how different restoration approaches interact with biochar addition to influence soil mineralization processes.

Nevertheless, the Ellenberg index is often calculated as the mean of its values for the species in a given phytocoenosis, often weighted by species abundance. The manuscript examines the merits of using the weighted median to calculate the Ellenberg index from both theoretical and practical perspectives. To this end, using phytosociological relevés describing a particular phytocoenosis describing the <em>Alopecuretum pratensis</em> association, we calculated the light, moisture, soil reaction, and fertility indices for the relevés using the two methods, and compared the resulting estimates of environmental conditions in the relevés. The findings, supported by a simulation study, reinforce the idea that the median provides a more accurate diagnosis of habitat characteristics and a clearer, more unambiguous interpretation of the index values obtained.

Machine learning (XGBoost-SHAP) and causal inference model (Causal Forest) were combined with land-use scenario simulation (PLUS model) to quantify the true causal effects of key landscape pattern factors on water quality (TN, TP, COD) across multiple scales and scenarios. The results challenged several conventional assumptions: (1) Significant context dependency was revealed.

For instance, the aggregation of production space improves water quality in mining-dominated areas but degrades it in agricultural zones. (2) The study provided the first causal evidence for a structure–function mismatch. Contrary to the traditional belief that ecological connectivity is beneficial, clustered ecological spaces under high pollution loads (mining and urban) exerted significant negative causal effects on water quality, indicating that their physical structure failed to translate into ecological purification functions and even facilitated pollutant transport. (3) Scale analysis and scenario simulation further indicated that ignoring context dependency and functional mismatch may lead to management failure or even adverse outcomes.
