To ensure effective conservation, it is essential to have a well-coordinated monitoring scheme. Therefore, we analyzed the functioning of naiad monitoring systems in 31 European countries. Monitoring of naiad populations is not coordinated in Europe, is largely unrelated to monitoring of water quality or host fish species, and receives irregular funding. Raw data on monitored species are typically unavailable, which hampers independent and/or large-scale analyses. The quality of EU monitoring schemes according to Article 17 of the Habitats Directive is poor for the most threatened species. To improve this, a new scheme is recommended with raw data stored in publicly available repositories to enable instant analysis and rapid, appropriate, evidence-based responses that can support the conservation of this imperilled taxon.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708793","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}

Their credibility depends on permanence—the expectation that biodiversity gains or sequestered carbon persist at least as long as the impacts they compensate for, or in perpetuity. Yet ecosystems are dynamic and increasingly exposed to disturbance, making perpetual outcomes difficult to guarantee. Despite this, many offset programs rely on fixed durations and static assumptions ill-suited to managing long-term risks, creating a structural misalignment between ecological permanence and the safeguards intended to secure it. To assess this misalignment, we reviewed three decades of literature to identify risks to long-term durability and strategies for managing them. We developed a typology spanning three domains. Non-physical risks, such as weak governance and limited data transparency, were most frequently reported, often co-occurred, and enabled other failures. Physical risks such as fire, storms, or flooding cause material damage and are intensifying with climate change. Methodological risks, including oversimplified metrics and flawed design, expose structural weaknesses in offset systems. Our typology provides a framework for assessing permanence risks and strengthening offset governance. Credible, enduring offsets are achievable, provided robust risk management and adaptive governance are aligned with ecological realities.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695438","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}

{"title":"From Alerts to Action: Operationalizing Real-Time Mortality Monitoring for Vultures","authors":"Corinne J. Kendall,&nbsp;Gareth Tate,&nbsp;Jes Lefcourt,&nbsp;Claire Bracebridge,&nbsp;Storm Crews","doi":"10.1111/con4.70048","DOIUrl":"10.1111/con4.70048","url":null,"abstract":"&lt;p&gt;In a recent Viewpoint, Santangeli (&lt;span&gt;2026&lt;/span&gt;) calls for integrating real-time mortality alerts into telemetry programs for vultures and other scavengers to combat the elevated poisoning crisis. We strongly support this call and highlight that such an approach is already being implemented at scale. Over the past decade, Endangered Wildlife Trust, The Peregrine Fund, and North Carolina Zoo have operationalized such an approach for African vultures through our &lt;i&gt;Eye in the Sky&lt;/i&gt; program (EITS), a near-real-time mortality monitoring network spanning 15 countries, more than 400 tagged birds, and more than 30 partner organizations. Since mid-2023, EITS has detected 46 wildlife poisoning events and 30 poison baits/sources across our southern African project sites, enabling reduced mortality, site decontamination, rescue of animals, and improved opportunities for evidence collection and enforcement. This has contributed to the prevention of substantial secondary mortalities, with a conservative calculation of ∼2500 vultures saved since inception. Building on this experience, we outline key operational challenges and solutions to translate alerts into effective action.&lt;/p&gt;&lt;p&gt;First, large-scale, long-term, partner-driven programs inevitably require working across multiple tag manufacturers. Tags can differ in transmission frequency, download structure, accessory sensors, and battery characteristics and alerts must account for these differences to function reliably. Freely available cloud-based databases and analysis platforms such as EarthRanger (ER) and Movebank provide important infrastructure to integrate and customize needs by tag type (Wall et al. &lt;span&gt;2024&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Second, alerts must be automated and multi-metric to ensure accuracy and use. Standard mortality alerts based on displacement can generate high false-positive rates. EITS incorporates additional tag data from accessory sensors into alert metrics. ER allows near-real-time alerts to be delivered via web interface, email, or WhatsApp.&lt;/p&gt;&lt;p&gt;Third, technological solutions are only effective if alerts reach the right people. With African vultures ranging widely, EITS depends on a broad network of over 30 partners spanning approximately 9 million km&lt;sup&gt;2&lt;/sup&gt; of southern and eastern Africa (Kane et al. &lt;span&gt;2022&lt;/span&gt;). Geographic alert-sharing capabilities allow mortality alerts to be shared directly with appropriate partners based on geographic proximity, regardless of where an animal was originally tagged.&lt;/p&gt;&lt;p&gt;Finally, the ability to reach a mortality site quickly can be as important as its detection. Models demonstrate that intervention within hours is necessary to reduce mortality during poisoning events (Murn and Botha &lt;span&gt;2018&lt;/span&gt;; Curk et al. &lt;span&gt;2025&lt;/span&gt;). Our program's success illustrates how near-real-time alerts, paired with coordinated response capacity, translate directly into conservation impact.

The Tugur River in the Russian Far East is perhaps the greatest stronghold of Siberian taimen (<i>Hucho taimen</i>) and large runs of anadromous chum salmon (<i>Oncorhynchus keta</i>) to this ecosystem may contribute to this conservation success. We combined analyses of stable isotopes, allometry, and body condition to assess the role of nutrient subsidies from salmon in sustaining this megafish stronghold. Siberian taimen relied on marine-derived nutrients throughout ontogeny, but the assimilation rate increased by a factor of &gt; 5.5 once they grew large enough to consume adult salmon whole. This marine resource constituted up to nearly 60% of the lifetime diet and 97% of the seasonal diet for large taimen. Salmon provided episodic pulses of direct nutrition and year-round ecosystem-wide benefits (including taimen prey that also assimilated marine-derived nutrients), enabling taimen to persistently maintain high body condition. Our findings underline key conservation lessons regarding the role of prey to guide conservation of freshwater megafish and other imperiled megafauna elsewhere.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://conbio.onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147642154","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}

To help address this gap, we assessed the extinction risk of 94 fungal species in monotypic genera, expected to have high evolutionary distinctiveness. Using IUCN Red List Criteria, most species were categorized as Data Deficient (56), 28 as Least Concern, with only nine assigned to threatened or near threatened categories, and one Not Evaluated. The prevalent data deficiency reflects severe knowledge gaps in fungal distribution, ecology, and taxonomy that impede evidence-based policy-making.
