Analyzing nine national, regional, and municipal climate plans, we assess whether cultural resources function as passive elements or active contributors to sustainable climate action. Using a systematic coding process, we categorize references into three dimensions—conceptualization, policy context, and governance treatment— providing a structured framework for evaluating their role and transformative potential. Seventeen recurring entry points emerge from the analysis, representing key actions that facilitate cultural resource integration into climate planning. These entry points reveal opportunities within governance frameworks to enhance cultural resource management in adaptation, risk reduction, and mitigation strategies. Rather than serving as prescriptive measures, they reflect common policy themes and suggest context-specific pathways to accelerate transformative governance. Our findings confirm widespread recognition of cultural resources in climate action and underscore the importance of stakeholder dialogue and the inclusion of both tangible and intangible cultural elements. However, significant gaps persist, including insufficient monitoring and evaluation mechanisms, weak cross-sectoral integration, and narrow definitions that hinder operationalizing intangible attributes. We conclude that fully leveraging cultural resources for transformative climate governance requires relational, reflexive, and multi-level approaches. Such strategies must optimize cultural resource management within existing governance systems while critically addressing broader unsustainable patterns—structural inequalities, sectoral silos, and rigid policy frameworks—that limit their transformative potential.</div></div>","PeriodicalId":313,"journal":{"name":"Environmental Science & Policy","volume":"171 ","pages":"Article 104127"},"PeriodicalIF":4.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308166","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}

Knight","doi":"10.1002/eap.70062","DOIUrl":"https://doi.org/10.1002/eap.70062","url":null,"abstract":"<p>The need to develop optimal restoration protocols for degraded grasslands has led to experimental research aimed at determining how different restoration treatments influence outcomes for biodiversity. The magnitude and direction of diversity responses to restoration treatments may depend on the spatial scale at which diversity is measured (local, regional), the metric of diversity used (Hill numbers), and the facet of diversity (taxonomic, functional, phylogenetic) considered. We conducted a long-term factorial experiment in a degraded grassland in Missouri, USA, in which we experimentally applied a regionally appropriate biodiverse seed mixture, added soil nutrients to restore soil fertility, and varied the timing in which the invasive plant <i>Lespedeza cuneata</i> entered the community. We used a unified framework of Hill numbers to evaluate how treatments influenced diversity, considering different spatial scales, metrics, and facets (taxonomic, phylogenetic, functional). We find that the timing in which the invasive <i>L. cuneata</i> entered the community had large effects on diversity, while nutrient addition had more limited effects. This was driven by the high dominance of the focal invasive when allowed to invade early in the growing season, suppressing diversity. The positive effects of late invasion increased in magnitude with spatial grain and were higher for taxonomic than phylogenetic and functional facets of diversity. This was largely due to the dominance of the focal invasive, negatively affecting diversity within specific plant families or functional phenotypes across treatments. Under early invasion, nutrients had a negative effect, particularly at local scales, inflating beta diversity in this treatment and resulting in negative to no effect of late invasion on many aspects of beta diversity. Our results demonstrate the importance of looking at a multitude of different measures of diversity to understand the relative effects of ecological restoration treatments combined with invasion timing. Efforts to keep noxious plant invaders out of a system early in restoration approaches better allow desirable, native plants to establish and can have long-term benefits for multiple aspects of diversity.</p>","PeriodicalId":55168,"journal":{"name":"Ecological Applications","volume":"35 4","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eap.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308847","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 allows the species to thrive in acidic soil with high toxic levels of Al. However, the information of ABC family in hydrangea and their roles underlying Al stress are still limited. This study performed a genome-wide characterization, expression analysis and functional assessment of the HmABC family members. The results showed that total 133 <em>HmABC</em> genes were identified from the genome of <em>H. macrophylla</em> ‘Bailer’, which were classified into eight subfamilies. Furthermore, numerous hormone-response and stress-related promoter <em>cis</em>-acting elements were identified within the <em>HmABC</em> genes. The expansion and duplication of <em>HmABC</em> genes were driven by whole-genome duplication (WGD), segmental duplication, and tandem duplication events. Co-expression analysis identified that 12 ABC members were of hub genes. Expression analysis indicated that these genes were induced in different tissues during Al treatment. Overexpression of certain <em>HmABC</em> genes showed that they can enhance the tolerance of yeast and <em>Arabidopsis</em> to Al by increasing gene expression levels, elevating Al accumulation, and boosting antioxidative enzymatic activities. This discovery lays a foundation for further exploration of the biological functions of <em>HmABCs</em> in hydrangea responding to Al stress, and is helpful for the phytoremediation of acid soils.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"18 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Our experiment aimed to examine how aridity affects biogenic weathering. The study was conducted along a gradient in Chile from humid to hyperarid climate (Atacama Desert), where photoassimilate production is increasingly limited by water stress. We hypothesize that biogenic weathering would cease if a threshold between element loss from denudation and energy demand for additional nutrient element mobilization by biogenic weathering is crossed, as competition between life for these elements becomes less intense when water supply limits biomass growth increasingly. We buried mesh bags containing freshly broken minerals, including biotite, muscovite and apatite along the gradient in Chile on granitic bedrock. Unexpectedly and in contrast to our initial hypothesis, we found that mineral weathering rates driven by mycorrhizal fungi under arid conditions were even proportionally higher, indicating a comparatively higher investment of photoassimilates into biogenic weathering by desert plants than by mediterranean, suggesting an adaptive mechanism. Additionally, biogenic weathering occurred at constant rates over a depth of up to 2.3 m, illustrating the constant mining of mycorrhizal fungi, irrespective of overall biological activity along the soil profile. The relative importance of biogenic weathering in arid climates furthermore points towards a fundamental function of biogenic weathering beyond nutrient mobilization by suggesting a regulatory role in overcoming long periods of missing soil water that prevent nutrient exchange from the soil matrix.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"990 ","pages":"Article 179891"},"PeriodicalIF":8.2,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
