Residential yards and gardens provide a multitude of benefits for people, including green infrastructure, access to nature, and improved mental health. Yards can also benefit wildlife by providing habitat, food and other resources. Previous studies have shown that people manage their gardens in different ways to attract or deter wildlife and that visible wildlife diversity can increase people’s investment in nature and resource provisioning. These relationships between people and wildlife could form feedbacks with long-term consequences for biodiversity, but the way that various factors, including observations and perceived presence of wildlife in residential gardens, affect people’s management decisions remains largely unexplored. To understand how these relationships shape yard management decisions, we organized and synthesized existing international scientific literature on wildlife gardening, identified major gaps in current knowledge, and suggest directions for future research that could improve our understanding of the dynamic, potentially reciprocal relationships between residents, their gardening behaviors, and wildlife. We identified 53 relevant studies from North America, South America, Europe, Oceania, Africa, and Asia. Most studies employed a qualitative approach to examine how attitudes toward wildlife influenced gardening behavior, with other determinants of wildlife gardening relatively understudied in the context of this literature search. Only five studies directly asked residents about wildlife observations or perceived presence of wildlife on their properties and related those observations to attitude or actual yard management behavior. For future research, we suggest that researchers measure multiple determinants of yard management decisions and conduct experimental and longitudinal studies to improve our understanding of the feedback loops between people and wildlife in residential landscapes.
住宅庭院和花园为人们提供了许多好处,包括绿色基础设施、接近自然和改善心理健康。院子还可以为野生动物提供栖息地、食物和其他资源。以前的研究表明,人们以不同的方式管理他们的花园来吸引或阻止野生动物,可见的野生动物多样性可以增加人们对自然和资源供应的投资。人与野生动物之间的这些关系可能会形成对生物多样性产生长期影响的反馈,但各种因素,包括观察和感知到的住宅花园中野生动物的存在,影响人们管理决策的方式,在很大程度上仍未被探索。为了了解这些关系如何影响庭院管理决策,我们组织和综合了现有的国际野生动物园艺科学文献,确定了当前知识的主要空白,并为未来的研究方向提出了建议,以提高我们对居民、他们的园艺行为和野生动物之间动态的、潜在的互惠关系的理解。我们从北美、南美、欧洲、大洋洲、非洲和亚洲筛选了53项相关研究。大多数研究采用定性方法来研究对野生动物的态度如何影响园艺行为,而在本文献检索的背景下,对野生动物园艺的其他决定因素的研究相对不足。只有五项研究直接询问了居民对野生动物的观察或对其财产中野生动物的感知,并将这些观察与态度或实际的院子管理行为联系起来。对于未来的研究,我们建议研究人员测量庭院管理决策的多个决定因素,并进行实验和纵向研究,以提高我们对住宅景观中人与野生动物之间反馈循环的理解。

Nitrogen (N) deposition and altered sowing patterns are key drivers of grassland community dynamics, influencing species interactions, resource allocation, and ecosystem functioning. However, the mechanisms through which N availability and sowing order shape competitive outcomes among co-occurring species remain poorly understood. Two dominant desert steppe grasses, Stipa breviflora (C3 grass) and Cleistogenes songorica (C4 grass) were sowed under three sowing treatments—mixed-sowing, S. breviflora-first sowing, and C. songorica-first sowing—combined with two N addition levels (0 and 20 kg N ha−1 yr−1). We found that N addition significantly increased plant height, tiller number, biomass, and N uptake in both species, but the magnitude of response varied with sowing pattern. C4 grass generally maintained stronger competitiveness and gained relative advantage under mixed sowing with N addition. N addition enhanced the competitive advantage of C4 grass in mixed-sowing treatment. However, priority effects resulting from sowing order dominated the competition between C3 and C4 grasses rather than N deposition and species-specific biological characteristics. δ¹⁵N analysis revealed that interspecific differences in N uptake were most pronounced at short competitive distances, with N addition amplifying dominance of C4 grass. These findings demonstrate that both resource availability and initial establishment order shape the trajectory of interspecific competition in grassland systems. This work provides new insights into grassland management under scenarios of increasing atmospheric N inputs and altered disturbance regimes.
氮沉降和播种模式的改变是草地群落动态的关键驱动因素,影响物种相互作用、资源配置和生态系统功能。然而,氮的可用性和播种顺序如何影响共生物种之间的竞争结果的机制仍然知之甚少。短句来源以短花针茅(C3草)和嵩草隐门草(C4草)两种优势荒漠草原禾草为试验材料,采用混播、短花针茅先播和嵩草先播3种不同施氮水平(0和20 kg N ha−1 yr−1)。结果表明,施氮显著增加了两种植物的株高、分蘖数、生物量和氮素吸收量,但其响应幅度因播种方式而异。在混播条件下,C4草总体保持较强的竞争力,获得相对优势。在混播处理下,氮肥增加了C4草的竞争优势。然而,播种顺序造成的优先效应主导了C3和C4禾草之间的竞争,而不是氮沉降和种特异性生物学特性。δ¹N分析显示,在短竞争距离下,种间的氮吸收差异最为明显,氮的添加放大了C4草的优势。这些结果表明,资源可得性和初始建立顺序共同塑造了草地系统种间竞争的轨迹。这项工作为增加大气氮输入和改变干扰制度下的草地管理提供了新的见解。

Social cost of deforestation in Brazilian biomes 巴西生物群落中森林砍伐的社会成本
IF 2.5 3区 环境科学与生态学 Q2 BIODIVERSITY CONSERVATION Pub Date : 2026-06-01 Epub Date: 2025-12-09 DOI: 10.1016/j.jnc.2025.127189

Determining the social cost of deforestation in each Brazilian biome is essential for supporting public policies and improving decision-making processes. This study conducts a systematic literature review of the economic valuation of native vegetation across Brazil’s six biomes, grounded in the Total Economic Value (TEV) framework. In addition to compiling and harmonizing existing estimates, we produced new values for biomes with information gaps, following procedures widely adopted in the international literature. After methodological harmonization— including the exclusion of components that were not comparable across studies— we established conservative ranges for the social cost of deforestation, expressed in 2025 U.S. dollars per hectare: Amazon (USD 822.20–20,521.35/ha), Cerrado (USD 529.48–5,999.04/ha), Atlantic Forest (USD 4,380.51–8,206.54/ha), Caatinga (USD 4,049.76–4,382.46/ha), Pampa (USD 532.53–5,993.83/ha), and Pantanal (USD 1,906.50–12,745.21/ha). The consolidated results presented here constitute the most comprehensive and comparable reference available for Brazil, providing robust parameters for cost–benefit analyses and for the design of environmental policy instruments.
确定每个巴西生物群落中毁林的社会成本对于支持公共政策和改进决策过程至关重要。本研究以总经济价值(TEV)框架为基础,对巴西六个生物群落的原生植被的经济价值进行了系统的文献综述。除了汇编和协调现有的估算值外,我们还根据国际文献中广泛采用的程序,为存在信息缺口的生物群系编制了新的值。在方法论上的协调,包括组件的排斥,并不具有可比性的研究,我们建立了保守的社会成本范围的森林砍伐,表达的每公顷2025美元:亚马逊(美元822.20 -20521 .35点/公顷),塞拉多(529.48美元-5999 .04点/公顷),大西洋森林(4380 .51 - 8206 - 54美元/公顷),Caatinga(美元4049点- 4382 .46 /公顷),南美大草原(USD 532.53 -5993 .83点/公顷),和潘塔纳(- 12745 .21 1906 .50美元/公顷)。这里提出的综合结果是巴西现有的最全面和最可比的参考资料,为成本效益分析和环境政策工具的设计提供了有力的参数。

Mapping stakeholders in plover bird conservation: An expert-based analysis of interest and influence 测绘鸻鸟保护的利益相关者:基于专家的兴趣和影响分析

In this study, a panel of 13 experts assessed a group of 34 stakeholders involved in the conservation of the Kentish plover (Anarhynchus alexandrinus), a shorebird that breeds in a coastal nature reserve located in central Italy. Stakeholders were assessed and grouped based on their level of influence and interest (as selected variables) in conservation objectives, following the Mendelow and Murray-Webster & Simon matrices. This expert-based approach allowed to group stakeholders into six groups: “Key Players”, “Context Setters”, “Subjects”, “People”, “Unconscious Saboteurs”, and “Time Bombs”, each requiring distinct strategies to reduce conflict with the target species and increase engagement. We observed an opposite pattern: “Key Players”—highly influential, interested, and motivated—contrast with “Time Bombs”, with low interest and high negative influence, who, conversely, threaten the target species and require careful management to prevent/mitigate negative impacts. “Unconscious Saboteurs” (high interest and high negative influence) comprise a highly heterogeneous and numerically significant category of stakeholders—summer beachgoers—who negatively impact the coastal habitats through dune trampling. However, they demonstrate strong conservation potential and could be raised through conservation education and communication strategies. These findings provide practical guidance for targeted operational conservation strategies at the local scale, compatible with the sustainable development of the coastal dune ecosystem.
在这项研究中,一个由13名专家组成的小组评估了参与保护肯特鸻(Anarhynchus alexandrinus)的34名利益相关者,这是一种在意大利中部沿海自然保护区繁殖的滨鸟。根据Mendelow和Murray-Webster & & Simon矩阵,根据利益相关者在保护目标中的影响力和兴趣水平(作为选定的变量)对其进行评估和分组。这种基于专家的方法允许将利益相关者分为六组:“关键参与者”、“背景设置者”、“受试者”、“人”、“无意识破坏者”和“定时炸弹”,每组都需要不同的策略来减少与目标物种的冲突并增加参与度。我们观察到一个相反的模式:“关键参与者”——极具影响力、兴趣和动机——与“定时炸弹”形成对比,他们兴趣低,负面影响大,相反,他们威胁到目标物种,需要仔细管理以防止/减轻负面影响。“无意识破坏者”(高兴趣和高负面影响)包括一个高度异质性和数字显著的利益相关者类别-夏季海滩游客-他们通过践踏沙丘对沿海栖息地产生负面影响。然而,它们具有很强的保护潜力,可以通过保护教育和宣传策略来提高。这些发现为在地方尺度上制定有针对性的操作保护策略提供了实践指导,与海岸沙丘生态系统的可持续发展相适应。

Synergies between potential key geoheritage areas (KGAs) and key biodiversity areas (KBAs) in Spain and Scotland: Toward a holistic nature conservation framework 西班牙和苏格兰潜在的关键地质遗产区(KGAs)和关键生物多样性区(KBAs)之间的协同作用:迈向整体自然保护框架

Geodiversity provides the abiotic foundation that shapes ecosystems and supports biodiversity. However, its role in conservation planning remains underrepresented. This study investigates spatial overlaps and functional linkages between potential Key Geoheritage Areas (KGAs) and Key Biodiversity Areas (KBAs) in Spain and Scotland, aiming to promote a more integrated conservation framework. Using national geosite inventories and the World Database of KBAs, we conducted spatial analyses and inferred ecological dependencies based on geological features and habitat data.
In Spain, 78% of the surface area of potential KGAs lies entirely within KBAs, despite KGAs covering only 1.7% of the total KBA area. These KGAs include volcanic, karstic, coastal, and tectonic systems that underpin habitats for protected species. In Scotland, all 40 globally important KBAs show inferred functional links to geoheritage, particularly through coastal geomorphology, soils, and hydrological systems supporting seabird and wetland species.
The results demonstrate that co-located KGAs and KBAs offer opportunities for integrated management, enhancing conservation effectiveness by recognizing the interdependence of abiotic and biotic systems. This innovative framework supports holistic conservation strategies, especially under climate change and land-use pressures. The study highlights the need for interdisciplinary approaches and skilled practitioners capable of managing both biodiversity and geoheritage within protected areas.
地质多样性为形成生态系统和支持生物多样性提供了非生物基础。然而,它在保护规划中的作用仍然没有得到充分的体现。本研究探讨了西班牙和苏格兰潜在的关键地质遗产区(KGAs)和关键生物多样性区(KBAs)之间的空间重叠和功能联系,旨在促进更综合的保护框架。利用国家地质遗址清查和世界地质bas数据库,我们进行了空间分析,并根据地质特征和栖息地数据推断出生态依赖关系。在西班牙,尽管KGAs仅占KBA总面积的1.7%,但潜在KGAs表面积的78%完全位于KBA内。这些KGAs包括支撑受保护物种栖息地的火山、岩溶、海岸和构造系统。在苏格兰,所有40个全球重要的kba都显示出与地质遗产的推断功能联系,特别是通过支持海鸟和湿地物种的沿海地貌、土壤和水文系统。结果表明,通过认识到非生物系统和生物系统的相互依存关系,共同定位的KGAs和KBAs为综合管理提供了机会,提高了保护效果。这一创新框架支持整体保护战略,特别是在气候变化和土地利用压力下。这项研究强调需要跨学科的方法和熟练的实践者来管理保护区内的生物多样性和地质遗产。

Mapping connectivity through tourism omniscape modeling reveals amphibian corridors in the Yangtze River Delta 通过旅游全景观模型绘制连通性图,揭示长三角两栖动物走廊

Tourist attractions, as specialized landscapes, provide recreational value for humans while simultaneously serving as critical habitats for numerous amphibian species. However, the ecological benefits and risks these sites pose to amphibians remain understudied. The Yangtze River Delta urban agglomeration, one of China’s most economically developed and densely populated regions, hosts extensive tourism infrastructure alongside 58 amphibian species. To quantify the modulating effects of attractions on amphibian movement connectivity, we simulated landscape connectivity for three amphibian species by constructing resistance surfaces based on habitat suitability derived from MaxEnt species distribution modeling, employing omnidirectional connectivity modeling for current flow analysis. This framework enabled the identification of connectivity-modulating attractions and species-specific corridors under three dispersal scenarios, alongside analyses of bidirectional “inhibition-enhancement” effects and land cover contributions to corridor composition. Results revealed both amphibian connectivity corridors and tourism attraction clusters exhibit spatial congruence in the southern Yangtze River Delta. This geographic overlap results in over 1,100 connectivity-modulating attractions. Urban attractions and Remote Natural attractions dominated the attraction typology (22% – 27% and 40% – 50% respectively). Connectivity-modulators demonstrate dual roles − inhibitory or facilitatory − contingent on species-attraction interactions. Urban attractions predominantly suppressed connectivity, whereas Remote natural attractions enhanced connectivity across all species. Cropland and forest collectively contributed > 80% to corridor area, followed by impervious surfaces and water. These findings could provide scientific foundations for reconciling tourism development with amphibian conservation in megacity clusters, directly supporting China’s ecological protection red line policy and global biodiversity targets.
旅游景点作为一种特殊的景观,为人类提供了娱乐价值,同时也是众多两栖动物的重要栖息地。然而,这些地点对两栖动物的生态效益和风险仍未得到充分研究。长江三角洲城市群是中国经济最发达、人口最密集的地区之一,拥有广泛的旅游基础设施和58种两栖动物。为了量化景点对两栖动物运动连通性的调节作用,基于MaxEnt物种分布模型得出的栖息地适宜性,构建阻力面,模拟了3种两栖动物的景观连通性,并采用全向连通性模型进行水流分析。该框架能够识别三种分散情景下的连通性调节景点和物种特定走廊,同时分析双向“抑制-增强”效应和土地覆盖对走廊组成的贡献。结果表明:长三角南部两栖动物连通性廊道和旅游景区集群均呈现空间一致性;这种地理上的重叠产生了超过1100个连接调制景点。城市景区和偏远自然景区在景区类型中占主导地位(分别为22% ~ 27%和40% ~ 50%)。连接调节剂表现出双重作用-抑制或促进-取决于物种吸引相互作用。城市景点主要抑制了所有物种的连通性,而偏远的自然景点则增强了所有物种的连通性。农田和森林共占走廊面积的80%,其次是不透水地表和水域。研究结果可为城市群旅游开发与两栖动物保护的协调提供科学依据,直接支持中国生态保护红线政策和全球生物多样性目标。

To quantify the modulating effects of attractions on amphibian movement connectivity, we simulated landscape connectivity for three amphibian species by constructing resistance surfaces based on habitat suitability derived from MaxEnt species distribution modeling, employing omnidirectional connectivity modeling for current flow analysis. This framework enabled the identification of connectivity-modulating attractions and species-specific corridors under three dispersal scenarios, alongside analyses of bidirectional “inhibition-enhancement” effects and land cover contributions to corridor composition. Results revealed both amphibian connectivity corridors and tourism attraction clusters exhibit spatial congruence in the southern Yangtze River <em>Delta</em>. This geographic overlap results in over 1,100 connectivity-modulating attractions. Urban attractions and Remote Natural attractions dominated the attraction typology (22% – 27% and 40% – 50% respectively). Connectivity-modulators demonstrate dual roles − inhibitory or facilitatory − contingent on species-attraction interactions. Urban attractions predominantly suppressed connectivity, whereas Remote natural attractions enhanced connectivity across all species. Cropland and forest collectively contributed &gt; 80% to corridor area, followed by impervious surfaces and water. These findings could provide scientific foundations for reconciling tourism development with amphibian conservation in megacity clusters, directly supporting China’s ecological protection red line policy and global biodiversity targets.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"91 ","pages":"Article 127221"},"PeriodicalIF":2.5,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145980256","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}

Planning theory and practice has placed considerable attention on the conservation of ecologically and culturally significant landscapes (ECSLs). A broad range of valuation systems have been proposed and implemented. This study performed a systematic literature review of 112 articles addressing the valuation of ECSLs to identify the landscape features that are most valued and why. The findings indicate that planning theorists and practitioners tend to follow material valuation approaches that prioritise the conservation and management of tangible landscape values. This trend has been traditionally driven by research and practice based in Europe, North America, Australia and Japan, and more recently from China. It follows more structured valuation systems such as the ecosystems services approach proposed by many international frameworks. In contrast, local landscape users assign value to landscape features depending on context-based experiences and aspirations that are underpinned by non-material valuation systems. The consideration of such intangible values could determine the extent to which stakeholders engage in landscape conservation. There is a need to develop more comprehensive valuation systems that can accommodate both material and non-material landscape values.
规划理论和实践对生态和文化景观的保护给予了相当大的关注。已经提出并实施了一系列广泛的估价制度。本研究系统地回顾了112篇关于生态环境景观评价的文章,以确定最受重视的景观特征及其原因。研究结果表明,规划理论家和实践者倾向于遵循物质价值评估方法,优先保护和管理有形景观价值。传统上,这一趋势是由欧洲、北美、澳大利亚和日本的研究和实践推动的,最近来自中国。它遵循更为结构化的评估体系,例如许多国际框架提出的生态系统服务方法。相比之下,当地景观使用者根据基于情境的体验和愿望为景观特征赋予价值,这些体验和愿望是由非物质评估系统支撑的。对这些无形价值的考虑可以决定持份者参与景观保育的程度。有必要发展更全面的估价系统,以适应物质和非物质景观价值。

Insects represent the largest component of global biodiversity, and widespread declines in their richness and abundance have raised concerns about ecosystem functioning. Yet insect communities in natural and semi-natural grasslands, and the drivers of their recent changes, remain poorly studied at broad spatial scales. In Illinois (USA), efforts to preserve and restore native tallgrass prairies have been ongoing for decades, but their impact on native insect communities remain poorly understood. We conducted a statewide assessment of Auchenorrhyncha communities (Hemiptera, hereafter ‘hoppers’) along a gradient of anthropogenic disturbance. By sampling both plants and hoppers across prairie habitats, we evaluated how management practices and habitat history influence hopper communities through direct and indirect (trophic) pathways. Using community-level analyses and structural equation modeling, we tested hypotheses regarding direct and indirect effects of management intensity, habitat type, and environmental factors on plant and hopper communities. Responses were assessed for prairie-dependent species (e.g., Flexamia grammica and Calamovilfa longifolia), overall species richness (plants and hoppers), and habitat quality indices (Floristic Quality Index, Auchenorrhyncha Quality Index [AQI]). Higher management intensity indirectly promotes hopper species richness through enhanced plant species richness. However, this pattern did not extend to the AQI, which declined significantly under high-intensity management in hill prairies, which currently serve as refuges for the remaining prairie specialist hoppers. These findings suggest that while prairie management benefits plant diversity, its effects on prairie-dependent insect communities are more complex and mediated by ecological and historical factors. Effective conservation of hopper communities may therefore require targeted, habitat-specific management strategies.
昆虫是全球生物多样性的最大组成部分,其丰富度和丰度的普遍下降引起了人们对生态系统功能的担忧。然而,在广泛的空间尺度上,对自然和半自然草地上的昆虫群落及其近期变化的驱动因素的研究仍然很少。在美国伊利诺斯州,保护和恢复本土高草草原的努力已经进行了几十年,但它们对本土昆虫群落的影响仍然知之甚少。我们沿着人为干扰的梯度对全州范围内的Auchenorrhyncha群落(半翅目,以下简称“跳虫”)进行了评估。通过对草原生境的植物和跳虫进行采样,我们评估了管理实践和生境历史如何通过直接和间接(营养)途径影响跳虫群落。利用群落水平分析和结构方程模型,验证了管理强度、生境类型和环境因子对植物和飞蛾群落的直接和间接影响。评估了草原依赖物种(如Flexamia grammica和Calamovilfa longifolia)、总体物种丰富度(植物和跳蝇)和生境质量指数(Floristic quality Index, Auchenorrhyncha quality Index [AQI])的响应。较高的管理强度通过提高植物物种丰富度间接促进了飞蛾物种丰富度。然而,这种模式并没有延伸到AQI,在高强度管理下,AQI显著下降,目前这些草原是剩余草原专科跳鸟的避难所。这些发现表明,虽然草原管理有利于植物多样性,但其对草原依赖昆虫群落的影响更为复杂,并受到生态和历史因素的调节。因此,有效保护跳虫群落可能需要有针对性的、针对栖息地的管理策略。

Threats to the conservation of protected natural areas in Mexico 对墨西哥自然保护区保护的威胁
IF 2.5 3区 环境科学与生态学 Q2 BIODIVERSITY CONSERVATION Pub Date : 2026-06-01 Epub Date: 2026-01-20 DOI: 10.1016/j.jnc.2026.127226

Protected Natural Areas (PNA) are a primary tool for conserving biodiversity and are used internationally. However, there is currently no decree ensuring their proper functioning, especially considering the rapid expansion of human activities. In Mexico, 182 PNA have been decreed, of which 125 terrestrial areas were analyzed to assess fragmentation and connectivity using land cover data from the MAD-Mex system (Monitoring Activity Data for the Mexican REDD + program) and a least-cost path modeling approach. A cluster analysis based on fragmentation metrics resulted in the formation of three groups of PNA, which were classified through discriminant analysis into low, medium, and high vulnerability levels. Subsequently, the extreme groups (low and high vulnerability) were characterized using nine socioeconomic variables, through a generalized linear model. The most vulnerable PNA are concentrated in the central region of the country, where population density, mining activity, and proximity to metropolitan areas increase fragmentation and reduce connectivity. A generalized linear model showed that the vulnerability of PNA increases with human population density and the presence of mines, while it decreases with distance to metropolitan areas and the presence of tourist areas. This analysis provides important insights into the local threats faced by each of Mexico’s terrestrial PNA. Such information is crucial for improving management plans and conservation strategies tailored to the specific threats confronting these areas.
自然保护区(PNA)是保护生物多样性的主要工具,在国际上得到广泛使用。但是,目前没有法令确保其适当运作,特别是考虑到人类活动的迅速扩大。在墨西哥,已经颁布了182个PNA,使用MAD-Mex系统(墨西哥REDD +计划的监测活动数据)的土地覆盖数据和最低成本路径建模方法,分析了其中125个陆地区域,以评估碎片化和连通性。基于碎片化指标的聚类分析将PNA划分为三组,并通过判别分析将其分为低、中、高脆弱性。随后,通过广义线性模型,利用9个社会经济变量对极端群体(低脆弱性和高脆弱性)进行了表征。最脆弱的PNA集中在该国的中部地区,那里的人口密度、采矿活动和靠近大都市地区加剧了碎片化,减少了连通性。广义线性模型表明,PNA的脆弱性随着人口密度和地雷的存在而增加,而随着距大都市的距离和旅游区的存在而降低。这一分析为了解墨西哥每一种陆地PNA面临的当地威胁提供了重要的见解。这些信息对于改进针对这些地区面临的具体威胁的管理计划和保护战略至关重要。

The prediction of species distribution is a cardinal tool for conservation and recuperation planning of medicinally and culturally important plant species. Climate change accompanied with anthropogenic pressures are the imperative factors in changing the alpine vegetation’s habitat and causing their natural habitat to shrink in numbers. Saussurea obvallata (DC.) Sch.Bip., is an important yet highly threatened medicinal herb of the Himalayan region. Overexploitation and unscientific harvesting have resulted in the steep decline of the plant’s natural habitat populations. The present study aims to the model the present and future distribution of S. obvallata, using MaxEnt in Uttarakhand state, India. The authors selected twenty-six variables (bioclimatic, topographic and pedologic) and 38 well-dispersed species occurrence points to predict the potential distribution of S. obvallata in Uttarakhand. Future distributions were projected under two Shared Socioeconomic Pathways (SSP2-4.5, SSP5-8.5) scenarios using two Global Circulation Models for the period 2021–2040 and 2041–2060. Results showed that the MaxEnt model was accurate, with the area under ROC (Receiver Operating Characteristic) curve reaching 0.9352 with isothermality, precipitation of warmest quarter, temperature of annual range, mean diurnal range and aspect emerging as the major contributing variables to the model. The study identified 1378.88 km2 high suitability area and 5135 km2 area with medium suitability for S. obvallata in Uttarakhand. The results of this study can be used to plan conservation strategies and prioritizing the highly suitable areas to be used as rehabilitation sites for S. obvallata. Overall, this study highlights an urgent need for instantaneous policy interventions to protect S. obvallata from habitat fragmentation, unscientific harvesting, and over exploitation.
物种分布预测是制定重要药用和文化植物物种保护和恢复规划的重要工具。气候变化和人为压力是导致高寒植被生境变化和自然生境减少的重要因素。雪莲(DC.)Sch.Bip。是喜马拉雅地区一种重要但受到高度威胁的草药。过度开发和不科学的采伐导致了该植物自然栖息地数量的急剧下降。本研究旨在利用MaxEnt在印度北阿坎德邦建立S. obvallata现在和未来分布的模型。选取生物气候、地形、土壤学等26个变量和38个分布较广的物种分布点,预测了北阿坎德邦白骨螺的潜在分布。利用两种全球环流模式预测了2021-2040年和2041-2060年两种共享社会经济路径(SSP2-4.5、SSP5-8.5)情景下的未来分布。结果表明,MaxEnt模型准确,ROC (Receiver Operating Characteristic)曲线下面积达到0.9352,其中等温、最暖季降水、年差温、平均日差和坡向是影响模型的主要变量。在北阿坎德邦确定了1378.88 km2的高适宜区和5135 km2的中等适宜区。本研究结果可用于规划保护策略和优先选择高度适宜的区域作为黑桫椤的恢复地点。总体而言,本研究强调迫切需要立即采取政策干预措施,以保护黑桫椤免受栖息地破碎化、不科学采伐和过度开发的影响。
