Globally, grasslands have been degraded due to overgrazing. Grassland losses and degradation negatively affect moth communities, yet moths function as herbivores, pollinators, and prey for birds, bats, and small mammals. Increasingly, biosolids, a resource recovered from municipal wastewater treatment, are being used as a restoration tool for degraded grasslands. Biosolids increase above-ground plant biomass and reduce bare ground, however, there is little research into effects on higher trophic levels. We tested whether biosolids application on arid grasslands in central British Columbia, Canada, changed moth abundances or communities 1–2 years after application. We found no difference in the abundances of macromoths or micromoths following biosolids application. Communities did vary: we captured 58 species of macromoths, and found lower species diversity in pastures treated with biosolids 2 years prior, but not 1 year prior. The three most common moth species were 64 % of all moths caught in 2nd year biosolids pastures, but only 38 % of all moths caught in control pastures. Biosolids application affected moth species diversity in the short-term, with effects varying with time since application. It would be valuable to determine whether biosolids-induced community changes of moths persist over longer time frames and to determine the mechanisms driving these changes.

在全球范围内，由于过度放牧，草原已经退化。草地的丧失和退化对飞蛾群落产生了负面影响，但飞蛾是食草动物、传粉者，也是鸟类、蝙蝠和小型哺乳动物的猎物。生物固体作为一种从城市污水处理中回收的资源，正越来越多地被用作退化草地的恢复工具。生物固体增加了地上植物生物量，减少了裸地，然而，对更高营养水平的影响的研究很少。我们测试了在加拿大不列颠哥伦比亚省中部干旱草原上施用生物固体是否会在施用1-2年后改变飞蛾的丰度或群落。我们发现应用生物固体后，大蛾和小蛾的丰度没有差异。群落确实有所不同：我们捕获了58种巨蛾，并且发现2年前使用生物固体处理的牧场物种多样性较低，但1年前没有。三种最常见的飞蛾占第二年生物固体牧场捕获的飞蛾总数的64%，而在对照牧场仅占38%。施用生物固体在短期内对飞蛾物种多样性有影响，影响随施用时间的变化而变化。确定生物固体诱导的飞蛾群落变化是否会持续更长时间，并确定驱动这些变化的机制，将是有价值的。

This study focuses on the identification and extraction of sand dunes, analysis of morphometric features, and prediction of active processes in desert areas, and employs Geographic Object-Based Image Analysis (GEOBIA) in desert environments. To achieve this goal, this study utilizes a combination of self-organizing maps (SOM), analytical hierarchy process (AHP), and decision tree (DT) algorithms to predict erosion risks caused by sand dune migration. This study also evaluates the relationship between sand dune morphometric features and active processes in diverse desert environments based on these features. Furthermore, to forecast climatic parameters and their relationship with sand dune morphometric features, the Long Short-Term Memory (LSTM) model is utilized. The results of the neural network analysis based on SOM indicate that transverse and barchan dunes are more susceptible to erosion hazards due to their irregular shape and broad distribution. Star dunes, however, exhibit higher stability and density, and this renders them less vulnerable. Moreover, the results of the correlation between dune morphometry and climatic parameters indicate higher hazards from barchan, star, and seif dunes due to their greater heat absorption than other types of dunes. Finally, climatic parameter prediction via the LSTM method, with R² accuracy of 0.8 and 0.9 and RMSE values of 0.11 for wind speed and 0.26 for temperature, respectively, suggests that the increase in aridity and wind speed in desert areas will intensify the migration of dunes in the future. Therefore, predicting environmental risks caused by sand dune movements and active processes in desert areas based on their morphometric characteristics facilitates better management of desert areas.

本研究主要围绕沙漠地区沙丘的识别与提取、形态特征分析和活动过程预测等方面展开，并在沙漠环境中应用基于地理目标的图像分析（geoobia）技术。为了实现这一目标，本研究采用自组织图（SOM）、层次分析法（AHP）和决策树（DT）算法相结合的方法来预测沙丘迁移带来的侵蚀风险。在此基础上，评价了不同沙漠环境下沙丘形态特征与活动过程的关系。此外，利用长短期记忆（LSTM）模型预测气候参数及其与沙丘形态特征的关系。基于SOM的神经网络分析结果表明，横向和barchan沙丘形状不规则，分布广泛，更容易受到侵蚀危害。然而，星沙丘表现出更高的稳定性和密度，这使得它们不那么脆弱。此外，沙丘形态与气候参数的相关结果表明，barchan沙丘、star沙丘和seif沙丘比其他类型的沙丘吸热更大，因此其危险性更高。最后，利用LSTM方法预测气候参数，风速和温度的R2精度分别为0.8和0.9，RMSE分别为0.11和0.26，表明未来沙漠地区干旱和风速的增加将加剧沙丘的迁移。因此，基于沙丘形态特征预测沙丘运动和活动过程所带来的环境风险，有助于更好地管理沙漠地区。

This study evaluated the efficacy of two plant growth-promoting rhizobacteria, Bacillus amyloliquefaciens and B. halotolerans, in alleviating the combined effects of drought and atmospheric dust stress on Camelina sativa L. under realistic field conditions in an arid region. A comprehensive factorial experiment arranged in a randomized complete block design implemented three irrigation intervals (4, 6, and 8 days) and two dust application levels, alongside treatments including control, individual bacterial inoculations, and a combined consortium. The research conclusively demonstrated that the simultaneous application of drought and dust stress was significantly more detrimental than each stressor applied in isolation. This synergistic stress combination severely reduced key indicators including nitrogen and phosphorus uptake, chlorophyll b content, final seed weight per plant, and root and shoot dry biomass, while concurrently increasing calcium concentration, soluble sugars, and carotenoid levels. Drought stress alone notably reduced seed yield and elevated phenolic compounds, whereas dust singularly increased chlorophyll b content without affecting phenols or yield. Crucially, inoculation with both bacterial strains, most notably with B. halotolerans individually, markedly improved the majority of physiological, nutritional, and functional traits, effectively enhancing overall plant resilience.

本研究在干旱区实际大田条件下，评价了解淀粉芽孢杆菌和耐盐芽孢杆菌两种促进植物生长的根瘤菌缓解干旱和大气粉尘胁迫对亚麻荠的影响。采用随机完全区组设计的综合因子试验采用3个灌溉间隔（4、6和8天）和2个施尘水平，同时处理包括对照、单独细菌接种和联合联合。研究结果表明，干旱和粉尘胁迫同时施用比单独施用的危害更大。这种协同胁迫组合严重降低了氮磷吸收、叶绿素b含量、单株最终种子重、根和地上部干生物量等关键指标，同时增加了钙浓度、可溶性糖和类胡萝卜素水平。干旱胁迫显著降低了种子产量，增加了酚类化合物含量，而粉尘只增加了叶绿素b含量，但不影响酚类物质或产量。重要的是，接种这两种菌株，尤其是单独接种耐盐芽孢杆菌，显著改善了大多数生理、营养和功能性状，有效提高了植物的整体抗逆性。

Given the impacts of climate change on increasing aridity, dune migration, and associated risks to adjacent areas and air quality, assessing these hazards is critical for effective land management. This study aims to utilize machine learning and deep learning algorithms to enhance image quality and delineate sand dune extents, identify optimal scales for extracting dune morphometric features, predict dune migration, and forecast climatic parameters and their relationships with morphometric characteristics. Results demonstrate that the deep iterative fusion network model effectively improves image quality for extracting dunes and their morphometric features with high accuracy. Furthermore, integrating morphometric and spectral features into a novel Land-Use Land-Form (LULF) map enables precise identification of landforms and objects in desert environments, including sand dune extents, with high accuracy. The findings also indicate that variations in spectral reflectance, particularly albedo and infrared bands, influence not only dune height detection but also dune migration speed. Additionally, the Markov model results suggest that increased albedo and infrared reflectance in the coming years will heighten the risk of dune migration in surrounding areas. Finally, the autoregressive integrated moving average model predicts future wind speeds ranging from 8.3 to 83.3 km/h, moving from southeast to northwest, reflecting intensified dune migration and increased risks to adjacent regions.

考虑到气候变化对干旱加剧、沙丘迁移的影响，以及对邻近地区和空气质量的相关风险，评估这些危害对有效的土地管理至关重要。本研究旨在利用机器学习和深度学习算法来提高图像质量和描绘沙丘范围，确定提取沙丘形态特征的最佳尺度，预测沙丘迁移，预测气候参数及其与形态特征的关系。结果表明，深度迭代融合网络模型有效提高了沙丘及其形态特征提取的图像质量，提取精度较高。此外，将形态测量学和光谱特征整合到一种新的土地利用地貌（LULF）地图中，可以高精度地精确识别沙漠环境中的地貌和物体，包括沙丘范围。研究结果还表明，光谱反射率的变化，特别是反照率和红外波段的变化，不仅影响沙丘高度探测，而且影响沙丘迁移速度。此外，马尔可夫模型结果表明，未来几年反照率和红外反射率的增加将增加周边地区沙丘迁移的风险。自回归综合移动平均模式预测未来风速为8.3 ~ 83.3 km/h，风向由东南向西北，反映了沙丘迁移加剧，对邻近地区的风险增加。

Epiphytes play a crucial role in ecosystem functioning but are highly vulnerable to habitat loss, particularly in dryland biomes like the Caatinga. In agricultural landscapes, remnant trees can function as important refuges, maintaining biodiversity despite land-use changes. This study evaluates the role of the Ouricuri palm (Syagrus coronata) in sustaining epiphyte diversity within grazing areas of the Caatinga. We surveyed 244 palms across three sites in Alagoas, Brazil, assessing the relationships between palm traits and epiphyte richness using generalized linear models. Our results revealed that 218 (91 %) of the palms taller than 2 m hosted epiphyte species in their crowns. Epiphyte richness was high (S = 28) and not influenced by palm diameter or leaf number but declined with increasing plant height. Beta diversity partitioning revealed high species turnover, primarily driven by variations in phorophyte traits. Functional group analysis showed that true epiphytes were favored by intermediate-height palms, while generalist species dominated on taller ones. These findings highlight the ecological importance of remnant S. coronata palms for epiphyte conservation in anthropized landscapes. Preserving these palms can enhance habitat connectivity, mitigate biodiversity loss, and support a wildlife-friendly agricultural model in the Caatinga.

附生植物在生态系统功能中起着至关重要的作用，但极易受到栖息地丧失的影响，特别是在像Caatinga这样的旱地生物群落中。在农业景观中，残树可以作为重要的避难所，在土地利用变化的情况下保持生物多样性。本研究评价了在卡廷加放牧区内，棕榈（Syagrus coronata）在维持附生植物多样性中的作用。我们调查了巴西阿拉戈斯3个地点的244棵棕榈树，利用广义线性模型评估了棕榈树性状与附生植物丰富度之间的关系。结果表明，218株（91%）高于2 m的棕榈树在其树冠上有附生植物。附生植物丰富度高（S = 28），不受棕榈径和叶数的影响，但随着株高的增加而降低。β -多样性分配揭示了高的物种更替，这主要是由光合植物性状的变化所驱动的。功能群分析表明，中等高度的棕榈树以真附生植物为主，而较高的棕榈树以多面手植物为主。这些发现强调了在人类化景观中，残余冠状棕榈对附生植物保护的生态重要性。保护这些棕榈树可以加强栖息地的连通性，减轻生物多样性的丧失，并支持卡廷加的野生动物友好型农业模式。

Climate change poses a significant threat to arid and semiarid ecosystems, where drought, high solar radiation, and extreme temperatures limit plant regeneration. This study evaluated whether nurse plants can mitigate the effects of global warming and enhance the survival of Coryphantha maiz-tablasensis, a threatened cactus endemic to the Chihuahuan Desert. The experiment was conducted in San Luis Potosí, Mexico, using open-top chambers to simulate warming in two contrasting habitats: an abandoned agricultural field and beneath the canopy of Neltuma laevigata (mesquite), a common nurse plant. Simulated warming significantly increased air temperature, particularly in open areas. Although rainfall and soil moisture were lower under the mesquite canopy, cactus survival was substantially higher in this habitat—100 % in control plots and 95 % in warming plots—compared to 90 % survival in open control plots and complete mortality in open warming plots. These findings indicate that direct exposure to elevated temperatures and solar radiation is lethal to saplings. The results underscore the critical role of N. laevigata in buffering microclimatic extremes and supporting cactus regeneration. Incorporating nurse plants into conservation and restoration strategies may help reduce population loss under future climate change scenarios and ensure the long-term persistence of threatened cactus species.

气候变化对干旱和半干旱生态系统构成重大威胁，干旱、高太阳辐射和极端温度限制了植物的再生。本研究评估了护理植物是否可以缓解全球变暖的影响，并提高奇瓦瓦沙漠特有的濒危仙人掌Coryphantha maiz-tablasensis的存活率。实验是在墨西哥的圣路易斯Potosí进行的，使用开顶室来模拟两个不同栖息地的变暖：一个是废弃的农田，另一个是在一种常见的护士植物Neltuma laevigata（豆科植物）的树冠下。模拟变暖显著提高了空气温度，特别是在开阔地区。尽管牧豆树树冠下的降雨量和土壤湿度较低，但与开放的对照区90%的存活率和开放的增温区完全死亡相比，该生境的仙人掌存活率明显更高——对照区100%，增温区95%。这些发现表明，直接暴露在高温和太阳辐射下对树苗是致命的。研究结果强调了仙人掌在缓冲极端小气候和支持仙人掌再生方面的重要作用。将护理植物纳入保护和恢复策略可能有助于减少未来气候变化情景下的种群损失，并确保受威胁仙人掌物种的长期持久性。

Land use and land cover (LULC) changes significantly impact hydrological processes in semi-arid regions like Iran, where national-scale studies are scarce. This study assesses LULC change impacts from 2001 to 2022 on runoff and hydrological drought across Iran's 576 catchments (410,000 km²) using the Soil and Water Assessment Tool Plus (SWAT+). This analysis employs a novel SWAT + framework integrating crop-specific calibrations (e.g., wheat, barley, rice), human interventions (e.g., irrigation, reservoir operations, interbasin diversions), and Curve Number (CN) dynamics, achieving robust performance (NSE: 0.50–0.88; KGE: 0.51–0.90). Evergreen forest loss (4.8 %–2.8 %) and agricultural expansion (20 %–27.8 %) increased annual runoff by 1.21 mm/month, with a 2.7 mm/month rise during the March–May rainy season, driven by 10–15 % reduced canopy interception and 5–10 % CN increases in arid catchments. Hydrological drought frequency rose 15 % in western and central catchments, with duration extending 1.2–1.8 months and severity increasing 5 %, linked to higher surface runoff (1.5–2.7 mm/month). Impacts were pronounced in arid and semi-arid regions (150–300 mm/year precipitation). This study advances LULC impact assessments by integrating runoff and drought analyses with CN dynamics, offering policy strategies like reforestation and precision irrigation for sustainable water management in semi-arid environments.

土地利用和土地覆盖（LULC）变化显著影响伊朗等半干旱地区的水文过程，而这些地区的国家级研究很少。本研究利用土壤和水评估工具Plus （SWAT+）评估了2001年至2022年LULC变化对伊朗576个流域（41万平方公里）径流和水文干旱的影响。该分析采用了一种新的SWAT +框架，整合了作物特定校准（如小麦、大麦、水稻）、人为干预（如灌溉、水库操作、流域间改道）和曲线数（CN）动态，实现了稳健的性能（NSE: 0.50-0.88; KGE: 0.51-0.90）。常绿森林损失（4.8% - 2.8%）和农业扩张（20% - 27.8%）使年径流量增加1.21 mm/月，其中3 - 5月雨季径流量增加2.7 mm/月，这是由于干旱流域林冠截流减少10 - 15%和CN增加5 - 10%造成的。西部和中部流域的水文干旱频率增加了15%，持续时间延长了1.2-1.8个月，严重程度增加了5%，与地表径流增加（1.5-2.7毫米/月）有关。在干旱和半干旱地区（150 ~ 300 mm/年）影响显著。本研究通过将径流和干旱分析与CN动态相结合来推进LULC影响评估，为半干旱环境下的可持续水管理提供再造林和精准灌溉等政策策略。

Cultivated land is indispensable for promoting sustainable socioeconomic development. Therefore, investigating crop growth is essential for ensuring the stable utilization of cultivated land. This study assessed the spatial and temporal variations in crop growth across hydrological years and investigated the mechanisms linking the temporal distribution of precipitation to crop phenological responses via an integrated analysis of the MODIS EVI and daily precipitation datasets (2002–2020). The findings indicated significant interannual variability in precipitation throughout the spring maize growing season, with only 23.33 % of the years classified as normal. Spatially, crop performance was better in the eastern and southern regions than in the western and northern regions. Crucially, the alignment between precipitation timing and crop phenological stage emerged as a more significant factor than total precipitation. When the timing of water availability mismatches crop water demands, even high precipitation levels may fail to support optimal growth. To increase water use efficiency, adaptive strategies are proposed: prioritizing water allocation during key growth stages, adopting diverse irrigation approaches, and maintaining water conservancy infrastructures. These outcomes are crucial for promoting the sustainable utilization of cultivated land and safeguarding ecological security in semiarid areas.

耕地是促进社会经济可持续发展的必要条件。因此，研究作物生长状况对确保耕地的稳定利用至关重要。本研究通过对MODIS EVI和日降水数据集（2002-2020）的综合分析，评估了不同水文年作物生长的时空变化，并探讨了降水时间分布与作物物候响应之间的联系机制。结果表明，在整个春玉米生长季，降水量具有显著的年际变化，只有23.33%的年份属于正常年份。从空间上看，东部和南部地区的作物生产性能好于西部和北部地区。重要的是，降水时间与作物物候期之间的一致性比总降水量更为显著。当水分供应时间与作物需水量不匹配时，即使高降水水平也可能无法支持最佳生长。为了提高水资源利用效率，提出了在关键生长阶段优先分配水资源、采用多种灌溉方式和维护水利基础设施的适应性策略。这些成果对促进半干旱区耕地可持续利用、保障生态安全具有重要意义。

Soil nematodes are an important component of underground communities and are highly sensitive to external disturbances and changes. Nitrogen deposition and dominant poisonous weeds are important factors contributing to global climate change. However, much less is known about the interaction between nitrogen deposition and poisonous weed on the taxonomic and functional diversity of nematode community on the Tibetan Plateau. We established a full factorial experiment between nitrogen addition treatment (nitrogen addition and ambient) with poisonous weed treatment (with Ligularia virgaurea and without Ligularia virgaurea) on the Tibetan Plateau. We quantified plant diversity, plant biomass, and edaphic properties to assess the effects of nitrogen addition and poisonous weed Ligularia virgaurea and their interactions on both taxonomic and functional alpha/beta diversity of soil nematode communities. Ligularia virgaurea indirectly decreased nematode taxonomic and functional beta diversity through plant biomass (standardized path coefficients: −0.2146) and directly increased nematode taxonomic and functional beta diversity (standardized path coefficients:0.1891 and 0.3470, respectively). Nitrogen addition directly (standardized path coefficients: −0.2069) and indirectly (through pH and plant biomass, standardized path coefficients: −0.3468 and 0.2144, respectively) affected nematode taxonomic and functional beta diversity. The interaction between Ligularia virgaurea and nitrogen addition indirectly decreased taxonomic and functional beta diversity through plant beta diversity (standardized path coefficients: 0.3665). Our results indicate a pattern of functional heterogeneity of nematode community following the expansion of poisonous weed Ligularia virgaurea, which highlights the important roles of poisonous weed in maintaining biodiversity and ecosystem functions and provides an alternative to realize the comprehensive utilization of poisonous weeds on the Qinghai-Tibet Plateau.

土壤线虫是地下群落的重要组成部分，对外界干扰和变化高度敏感。氮沉降和优势毒草是导致全球气候变化的重要因素。通过定量分析植物多样性、生物量和土壤特性，评价氮肥添加和毒草对土壤线虫群落分类和功能α / β多样性的影响。甜瓜通过植物生物量间接降低线虫的分类和功能β多样性（标准化路径系数为- 0.2146），直接增加线虫的分类和功能β多样性（标准化路径系数分别为0.1891和0.3470）。氮的直接添加（标准化通径系数为- 0.2069）和间接添加（通过pH和植物生物量，标准化通径系数分别为- 0.3468和0.2144）影响了线虫的分类和功能多样性。加氮与黄橐吾的交互作用通过植物β多样性间接降低了植物的分类和功能β多样性（标准化通径系数为0.3665）。

Integrating traditional irrigation knowledge with modern sustainable water management practices offers valuable solutions to water scarcity in arid regions. The Middle East and North Africa (MENA) region faces significant climate challenges, including low rainfall, rising temperatures, and recurrent droughts. As sustainable agriculture requires harmony between humans and nature, managing scarce water resources is crucial for adapting to climate change and ensuring agricultural resilience in these arid environments. Communities in this region have historically addressed water scarcity by developing traditional and locally adapted irrigation techniques, such as Qanats and rainwater harvesting. These methods have been essential in conserving water resources and mitigating environmental stressors that impact agricultural productivity. This paper examines how traditional irrigation practices contribute to the sustainability and resilience of agricultural systems and the preservation of fragile arid ecosystems in the face of climate uncertainties. The study provides: (i) an analysis of water scarcity issues and the effects of climate change on arid ecosystems in the MENA region, (ii) an exploration of traditional irrigation knowledge and technologies, emphasizing their role in water conservation and ecosystem health, and (iii) a discussion of socio-economic, institutional, and technological barriers to broader adoption of these practices. Case studies from various MENA countries illustrate how traditional practices enhance resilience and support conservation efforts. The paper highlights the importance of culturally appropriate strategies integrating human dimensions into ecosystem management, fostering sustainable and adaptive solutions for the region's challenges.

将传统灌溉知识与现代可持续水资源管理实践相结合，为干旱地区的水资源短缺提供了宝贵的解决方案。中东和北非（MENA）地区面临着重大的气候挑战，包括降雨量少、气温上升和经常性干旱。由于可持续农业需要人与自然和谐相处，管理稀缺的水资源对于适应气候变化和确保农业在干旱环境中的恢复力至关重要。历史上，该地区的社区通过开发传统的和适合当地的灌溉技术来解决水资源短缺问题，例如坎坎井和雨水收集。这些方法对于节约水资源和减轻影响农业生产力的环境压力至关重要。本文研究了传统灌溉方式如何在气候不确定性面前促进农业系统的可持续性和复原力，以及保护脆弱的干旱生态系统。该研究提供：(i)分析缺水问题和气候变化对中东和北非地区干旱生态系统的影响；（ii）探索传统灌溉知识和技术，强调其在水资源保护和生态系统健康方面的作用；（iii）讨论广泛采用这些做法的社会经济、体制和技术障碍。来自中东和北非各国的案例研究说明了传统做法如何增强复原力并支持保护工作。本文强调了将人文因素纳入生态系统管理、促进可持续和适应性解决方案以应对该地区挑战的重要性。
