Yet, knowledge gaps in fish distribution and habitat use limit the implementation of efficient marine conservation strategies within fjords. Using five British Columbia fjords as a case study, we demonstrated that eDNA metabarcoding combined with species traits can enhance the detection and monitoring of conservation priority species (CPS) within systematic conservation planning frameworks. Spatiotemporal eDNA patterns confirmed the presence of endangered eulachon (Thaleichthys pacificus) across three fjords and identified deep fjord habitats as conservation priorities for mesopelagic species, including sensitive elasmobranchs and diel vertical migrators such as northern lampfish (Stenobrachius leucopsarus). eDNA peaks for several CPS during winter and spring matched documented spawning windows, underscoring the importance of fjords as seasonal spawning habitat. This globally transferable approach can supplement local stewardship initiatives and long-term monitoring efforts, contributing to more effective marine conservation area design and management.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 3","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

In order to reverse the decline of biodiversity on approximately 47% of the world's cropland, it is necessary to expand the range of available tools, including novel approaches. Most of the business efforts to enhance sustainability in agricultural supply chains have been focused on the tropics. Globally important temperate crops like cereals and oilseeds are left largely unchecked. But implementation of voluntary sustainability standards to restore biodiversity in temperate and Mediterranean biomes would require doing things differently than in tropical commodities. Temperate agriculture differs both in its operations (lack of divergence between staples and cash crops, crop rotation) and landscape context (lack of agricultural expansion frontiers, complex pressures on biodiversity). Consequently, agricultural certification and similar schemes need to be linked primarily to a unit of space rather than to a specific commodity. Farmers’ engagement in the development, design, and operation of standards is important. However, necessary tools such as advanced criteria, metrics, and data infrastructure are largely lacking in temperate agriculture, and their development depends on input from conservation scientists and practitioners.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 3","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Yet, conflicts with farmers over livestock predation following European colonization led to widespread lethal control. These measures are further reinforced by perceptions of hybrid ancestry with European dogs. Accurate estimation of European dog ancestry is, therefore, essential for effective conservation, but existing tests yield highly conflicting results. Leveraging precolonial dingo paleogenomes and a robust ancestry modeling framework, we reassess the genetic ancestry of contemporary populations. Our approach corrects limitations and biases in existing methods, producing consistent estimates even with as few as 10,000 genome-wide transversion genetic markers. Accounting for admixture uncovers population structure that has persisted for over two millennia and reveals patterns of genetic admixture coinciding with human activity during the colonial era. This study underscores the value of paleogenomes as a vital conservation tool, offering insights unattainable from modern DNA alone. By clarifying ancestry and population structure, our study offers a robust foundation for effective regionally informed dingo management across Australia.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 3","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Yet their recognition and representation in global environmental governance remain uneven. Despite decades of stewardship, IPLCs—particularly in South Asia—face systemic underrepresentation driven by epistemic and structural injustices. In India, this is compounded by the absence of formal recognition of “Indigenous Peoples,” with the administrative category “Scheduled Tribes” misaligned with international definitions of indigeneity. Drawing on field-based engagement, lead author's insights, and analysis of existing literature, we show how traditional governance systems offer culturally embedded, inclusive approaches that extend beyond the technocratic framing of Nature-based Solutions. We argue that mismatches in terminology contribute to recognition injustice, limiting IPLCs’ participation in governance and access to conservation finance. Beyond calls to decolonize conservation discourse, we emphasize the need for reparative justice to redress historical exclusion, restore land rights, and support IPLC-led conservation. We call for policy frameworks to recognize IPLCs governance systems, ensure direct access to conservation finance, and embed culturally grounded Nature-based Approaches (NbA) in biodiversity planning as essential for just and transformative change as envisioned in the Kunming–Montreal Global Biodiversity Framework and IPBES.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 3","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70060","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Encompassing the Amazon coast, the region is entering a new phase of industrial expansion. In 2025, Brazil issued its first offshore oil exploration license in two decades, opening the door to large-scale hydrocarbon development. This decision comes amid renewed global commitments to climate following COP30, highlighting persistent policy tensions between energy expansion and sustainability. Here, we present a spatially explicit assessment of cumulative oil spill risk across Brazil's Equatorial Margin. By integrating oceanographic modeling of spill trajectories with habitat distribution and vulnerability scores, we mapped cumulative risk across marine habitats in all sedimentary basins and identified where risk overlaps with conservation priorities. Results indicate that the Potiguar Basin contributes most strongly to cumulative risk for seagrass meadows, rhodolith beds, coral reefs, and seamount ecosystems. In contrast, the Foz do Amazonas Basin presents comparatively lower overall risk, although planned activities there increase projected risk for mesophotic reefs. Building on these insights, we outline policy actions—including strengthened ecological monitoring, improved spill preparedness, and expansion of marine protected areas—to improve governance as offshore oil development is considered along Brazil's Equatorial Margin.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 3","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148047433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
