The Chinese subtropical evergreen broadleaved forest, a region with a high net carbon sink rate, is currently experiencing climatic warming and changes in precipitation patterns that may increase aridity and alter stand structure. Understanding how competition and climate impact the radial growth of evergreen broadleaved tree species in this region remains unclear. To address this gap, we collected data on competition and tree-ring width from 15 natural <em>Schima superba</em> stands across a large subtropical region using dendroclimatology. We simulated multi-year accumulative radial growth (G_T) over the most recent 5, 10, 15, and 20 years using six distance-independent competition indices in linear mixed-effects models. Our findings revealed that the competition index representing the number of greater competitors than the focal tree (NGR) best explained the 20-year accumulative radial growth (G₂₀) in linear mixed-effects models, with the highest marginal and conditional R² values (0.39 and 0.70, respectively). Additionally, we found that temperatures in April had significant positive effects on tree radial growth (T4, <em>r</em> = 0.674, <em>P</em> &lt; 0.05; Tmax4, <em>r</em> = 0.655, <em>P</em> &lt; 0.05), while temperature in the coldest month (January) and September and the relative humidity in May had significant negative effects on tree radial growth (T9, <em>r</em> = − 0.434, <em>P</em> &lt; 0.05; Tmin9, <em>r</em> = − 0.465, <em>P</em> &lt; 0.05; Tmin1, <em>r</em> = − 0.349, <em>P</em> &lt; 0.05; RH5, <em>r</em> = − 0.412, <em>P</em> &lt; 0.05), respectively. The best model, which included NGR, Tmin9, Tmin1, and RH5 explained 64 % of the variance in G₂₀, with relative contributions of 71.24 %, 11.24 %, 13 %, and 4.5 % respectively. These results suggest that competition and temperature are key drivers of radial growth in <em>Schima superba</em> within these humid subtropical forests. Our findings also indicate that appropriate thinning practices targeting large trees could enhance radial growth, helping these forests adapt to climatic warming and increasing aridity.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"172 ","pages":"Article 113287"},"PeriodicalIF":7.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Assessing the site conditions under which trees are vulnerable to drought damage provides key information for the establishment of countermeasures to prevent such damage. This study aimed to clarify the differences in drought vulnerability of young planted forests between regions and species by using forest insurance claims from all over Japan as a damage indicator. We targeted the two most damaged species in two of the most drought-affected regions from 2016 to 2021. Although landform and soil type were found to be influential factors in the Kamikawa Subprefecture of Hokkaido, these factors did not affect the drought damage in Yamaguchi Prefecture. In Kamikawa, the drought damage risk was high for <em>Larix kaempferi</em> on river terraces and for <em>Abies sachalinensis</em> on mountain areas with compacted brown forest soil. Clayey soil, which can prevent plants from absorbing water, has been known to distribute on the terraces and the mountains with compacted soil in Kamikawa. Therefore, our analysis identified clayey soil as a cause of drought vulnerability in Kamikawa. In addition, <em>L. kaempferi</em> was suggested to be especially vulnerable on flat terraces with less permeable clayey soil due to root damage associated with excessive soil moisture before drought. This study demonstrated that forest insurance can be used not only for damage compensation, but also as a source of information for identifying region- and species-specific risk factors for meteorological damage in forests.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"172 ","pages":"Article 113290"},"PeriodicalIF":7.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This impact is particularly pronounced in the Greater Khingan Mountains, where forest cover has remained consistently high over time. Understanding and quantifying how variations in tree species composition affect watershed hydrology is essential for effective management and conservation efforts in this region. This study utilized daily runoff, baseflow separation, and various remote sensing evapotranspiration data to develop an accurate SWAT model for the Tahe River Basin, a typical forest watershed in the Greater Khingan Mountains. We assessed how the proportions of the dominant tree species, <em>Larix gmelinii</em> and <em>Betula platyphylla</em>, influence streamflow components and evapotranspiration. The results show that increased proportion of <em>Larix gmelinii</em> significantly enhances the hydrological function. Specifically, a 10% increase in <em>Larix gmelinii</em> leads to a 0.64 mm decrease in evapotranspiration, and increases runoff and baseflow by 0.66 mm and 4.98 mm, respectively. The effects of the conversion between <em>Larix gmelinii</em> and <em>Betula platyphylla</em> on these hydrological components become more pronounced under wetter conditions. Simulations based on two CMIP6 future climate scenarios indicate a trend towards warmer and wetter conditions in the Tahe River Basin, leading to further increases in runoff and evapotranspiration. <em>Larix gmelinii</em> is crucial for maintaining future baseflow, to stabilize baseflow and manage extreme drought events, <em>Larix gmelinii</em> proportions of 30% under SSP245 and 90% under SSP585 are recommended. The findings reveal the sensitivity of subboreal permafrost hydrology to forest composition changes and offer critical insights for climate adaptation strategies.

The presence of warm and humid air currents significantly contributes to the intensity of rainfall in piedmont areas, thereby exposing them to heightened risks of waterlogging and flash floods. In response, there is a growing inclination towards adopting nature-based solutions (NbS) for effective flood regulation. This study proposes a kind of NbS for flood management in the piedmont area: using the SCS-CN hydrological model to measure the supply of flood regulation ecosystem service (FRES) in the study area, while employing the random forest model to enhance the accuracy of FRES demand assessment. The matching degree between FRES supply and demand was analyzed at two granularities of sub-catchments and grids. Ultimately, the supply–demand relationship was optimized in terms of both in-situ services and directional services. Taking Fangshan District and Zhuozhou City in China as a case study, the findings demonstrate that: (1) The random forest model can accurately predict the inundation probability across the entire domain using limited data, with areas of highest hazard typically characterized by high construction intensity, low vegetation cover, and low topography. (2) At the sub-catchment granularity, the low supply-high demand areas exhibit a faceted distribution within urban built-up areas and the transition area between mountains and plains. At the grid granularity, the low supply-high demand areas are distributed in a point-like manner in high-intensity development lots. (3) Based on the results of supply–demand matching, a zoning management scheme integrating NbS for ecological protection, restoration, and flood control interventions is proposed. A total of 31 flood regulation service flow corridors were identified along with optimization strategies provided. The results of the study can inform flood resilience planning in piedmont areas from the perspective of promoting a balance between FRES supply and demand.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"172 ","pages":"Article 113274"},"PeriodicalIF":7.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143511202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

China’s highly uneven lake distribution and pronounced spatial variations in lake-area changes have remained unclear. The study aimed to understand the patterns and underlying drivers of lake-area changes in China over the past 34 years, focusing on regional variations influenced by climatic (temperature, precipitation, and climate water deficit), hydrological (runoff, snow water equivalent, palmer drought severity index, and soil moisture content), and human (farmland area, building area, fractional vegetation cover, population, gross value of industrial output, total output value of primary production, and gross domestic product) factors. The Google Earth Engine (GEE) platform and Landsat series remote sensing images were enlisted. Catering to regional variations in natural and cultural traits, five water indices extracted the areas of lakes and reservoirs larger than 50 km2 in China’s five major lake regions. Factor analysis and Mann-Kendall trend analysis identified relevant drivers. Mann-Kendall trend analysis explored the influence of factors on abrupt changes in lake area. Based on the correlation strength identified through factor analysis, factors weakly correlated with lake area were excluded, thereby reducing redundancy in the input for PLS-SEM. Finally, Partial Least Squares Structural Equation Modeling (PLS-SEM) quantitatively investigated the complex relationships and interactions among the potential factors. The results indicated differential extraction effectiveness of the five water indices for the lake regions. MNDWI effectively extracted lakes in the Qinghai-Tibet Plateau Lake Region (QTP_LR) and Northeast Plain and Mountain Lake Region (NPM_LR). NDWI, WI2019, and AWEI performed the best in the Eastern Plain Lake Region (EP_LR), Mong-Xin Plateau Lake Region (MXP_LR), and Yunnan-Guizhou Plateau Lake Region (YGP_LR), respectively. From 1990 to 2023, the trends in lake-area changes varied across regions. EP_LR shrank continually, whereas MXP_LR and QTP_LR expanded significantly. NPM_LR initially shrank and then expanded, whereas YGP_LR remained relatively stable. The responses of lake-area changes to drivers varied notably across regions, necessitating variable screening to reduce SEM model redundancy. The influence of natural (climatic and hydrological) and human factors on lake areas differed among regions. QTP_LR responded strongly to climatic factors, while other regions were more sensitive to human factors.

The structure of the forest stand and the horizontal composition of the canopy play a major role on the light regime of the understory, which in turn affects the abundance and the diversity of the understory plant community. Reliable assessments of canopy structural attributes are essential for forest research and biodiversity monitoring programs, as well as to study the relationship between canopy and understory plant communities. Canopy photography is a widely used method but it is still not clear which photographic techniques is better suited to capture canopy attributes at stand-level that can be relevant in forest biodiversity studies. For this purpose, we collected canopy structure and understory plant diversity data on 51 forest sites in the north-eastern Italian Alps, encompassing a diversity of forest types from low-elevation deciduous, to mixed montane stands to subalpine coniferous forests. Canopy images were acquired using both digital cover (DCP) and hemispherical (DHP) photography, and analysed canopy structural attributes. These attributes were then compared to tree species composition data to evaluate whether they were appropriate to differentiate between forest types. Additionally, we tested what canopy attributes derived from DCP and DHP best explained the species composition of vascular plants growing in the understory. We found that hemispherical canopy photography was most suitable to capture differences in forest types, which was best expressed by variables such as leaf inclination angle and canopy openness. On our sites, DHP-based canopy attributes were also able to better distinguish between different conifer forests. Leaf clumping was the most important attribute for determining plant species distribution of the understory, indicating that diverse gap structures create different microclimate conditions enhancing diverse plant species with different ecological strategies.
