Using remote sensing and field surveys from 2001 to 2017, we examined FPA coverage, their efficacy in preventing species decline and habitat deterioration, and strategies to enhance FPA effectiveness for the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis). FPAs failed to cover nearly half of high-abundance regions and two thirds of medium-abundance areas. Despite initially better conditions, FPAs experienced similar or greater species declines and habitat deterioration. Porpoise distribution closely correlated to habitat conditions, with abundance declining most in severely degraded floodplains while remaining stable or increasing in less disturbed areas. To improve FPA performance, we recommend expanding protection to medium- and high-abundance areas to better cover key porpoise habitats and enhancing existing FPAs through stricter law enforcement, proactive management, and targeted restoration. These strategies are reinforced by China's new legal and policy framework for Yangtze River protection, providing a foundation for long-term conservation.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849291","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}

Using comprehensive geographic and genomic sampling combined with approaches that integrate DNA with environmental and climatic datasets, we assessed the population genetic structure, demographic histories, and vulnerability to future climate change in three out of four extant horseshoe crab species, all centered in Asia. Our study highlights that the Sunda Shelf, a complex and dynamic shallow-marine landscape, has been the sole repository of most genetic diversity among all three Asian species, and therefore crucial to the long-term survival of horseshoe crabs. Our study not only provides the first genomic baseline data for the evaluation of Asian horseshoe crabs’ conservation status but also identifies core habitats that potentially act as refugia and corridors for Asian horseshoe crab populations with impending anthropogenic global warming.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825283","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 contrast, Indigenous people continue to advocate the need for land and seascape approaches that include all aspects of life, particularly the special relationship between Kin (people), Country, and Knowledge. Globally, Indigenous people are lobbying for environmental research to take a rights-based approach that improves economic opportunities; confers greater authority over the stewardship of Country; delivers equity in managing Country; emboldens control to integrate knowledge systems; values and promotes culture; and recognizes Indigenous self-determination. In Australia, the National Indigenous Environment Research Network (NIERN) proposal offers a solution that supports the rights-based approach driven by Indigenous Australians through the establishment of a community of practice guided by Indigenous researchers and Indigenous Knowledge holders. We describe this Indigenous-led solution to the self-determination of Indigenous environmental research priorities by exploring the concept, the authorizing environment, and the mutual benefits that could be delivered by such a network. The empowerment of Indigenous people in research is possible if an all-of-system approach is taken. This approach must involve Indigenous people in all decision-making processes including the development of research priorities, the design of methodologies, the interpretation of findings, and finally the evaluation of outputs and outcomes.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825285","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}

However, when multiple communities access the same resource, these long-distance relationships could generate interdependence and trust to motivate engagement in collective action to manage the resource. To test this, we interviewed 1317 people in 28 fishing villages in Tanzania about their participation in managing open-access fisheries and their social relationships in each village accessing the fishery. People with more friends in other villages trusted more people in those villages and were more likely to participate in collective action to manage the shared fishery, such as reporting others for destructive fishing practices. These results show that long-distance relationships may be a useful foundation upon which to build conservation efforts that cross community boundaries and bolster sustainable resource use.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13073","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777439","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 evidence for this analogy was lacking for the European native species Ostrea edulis. Historical data provide a unique opportunity to develop a robust definition for this ecosystem type, confirm that O. edulis are large-scale biogenic reef builders, and assess its current conservation status. Today, O. edulis occur as scattered individuals or, rarely, as dense clumps over a few m2. Yet historically, O. edulis reef ecosystems persisted at large scales (several km2), with individual reefs within the ecosystems present at the scale of several hectares. Using the IUCN Red List of Ecosystems Framework, we conclude the European native oyster reef ecosystem type is collapsed under three of five criteria (A: reduction in geographic distribution, B: restricted geographic range, and D: disruption of biotic processes and interactions). Criterion C (environmental degradation) was data deficient, and Criterion E (quantitative risk analysis) was not completed as the ecosystem was already deemed collapsed. Our assessment has important implications for conservation policy and action, highlighting that the habitat definitions on which conservation policies are currently based reflect a highly shifted baseline, and that the scale of current restoration efforts falls far short of what is necessary for ecosystem recovery.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776671","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}

This creates a conundrum for conservation and invasion science. We analyzed the distributions, introduction pathways, threats, and conservation strategies of threatened mammals with alien populations globally. We reassessed their hypothetical IUCN Red List category including the alien part of the range. Among 230 alien mammals, 36 are threatened in their native range, either critically endangered (17%), endangered (25%), or vulnerable (58%). These species were mainly introduced for hunting and exchanged within Asia, with introduced ranges concentrated in south-eastern Asia and eastern Australia. They face multiple threats, particularly from biological resource use. Conservation strategies are mainly related to species management. Including alien populations in the assessments reduces extinction risk of 22% of the species. Although some of these alien populations may have conservation value, conservation managers should carefully consider them on a case-by-case basis to avoid negative impacts on biodiversity.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777437","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}

Sustaining the services they provide will require managing resilience, particularly with increased volatility from climate change. Portfolio theory is touted as a mechanism to increase resilience in ecosystems because it takes advantage of temporal volatility in local production dynamics to increase stability at larger spatial scales. Using an individual-based model of a network of artificial reefs across multiple seagrass ecosystems that is parameterized with 15 years of field data, we demonstrate that (1) the large fish populations and the low enrichment synergistically increase portfolio effects; (2) the mechanism was via reduced local and increased meta-ecosystem stability in primary production; and (3) stability was greatest under intermediate production because nutrient enrichment reduces and fish, which have less influence on the amount of production, promote stability. Integrating common-sense management with portfolio theory can stabilize the services provided by seagrass ecosystems.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 6","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684495","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}

However, concerns persist about the sustainability of hunting practices within these territories. This study investigates the long-term impact of Indigenous hunting practices on wildlife populations in the Cofán territory of Zábalo, Ecuador. We employed line transect surveys to estimate wildlife densities over three periods (2001–2003, 2006–2009, and 2018), focusing on 16 species that are integral to local livelihoods and subject to community management. Our results indicate generally stable or increasing populations for most species, particularly in nonhunted areas, where spatial restrictions are enforced. The Cofán's ability to sustainably manage relations between humans and wildlife is largely attributable to their adaptive management system, which includes species-specific regulations and spatial zoning, and is realized through community decision-making, knowledge sharing, and an ethos of care. These findings demonstrate that Indigenous stewardship can effectively sustain biodiversity in complex biocultural systems. The study underscores the importance of integrating Indigenous knowledge with scientific approaches to achieve long-term conservation goals.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 6","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599953","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}
