Opportunities to conserve the entire carnivore guild are frequently overlooked by channeling conservation and mitigation efforts into single-species conservation. We synthesize experiences across Asia to explore these challenges and propose mitigations to maximize conservation benefits for the entire carnivore guild. Seven challenges for wolves (Canis lupus) in Asia are highlighted: wolves (1) have been neglected over decades of single-species conservation, (2) receive less cultural appreciation in many regions, (3) are subject to lax legislation and law enforcement, (4) are often blamed disproportionately for livestock depredation, (5) are often considered more abundant than they are, (6), receive disproportionately little attention from the scientific and conservation communities relative to their ecological importance, and (7) are threatened ecologically and genetically by increasing feral dog populations. As a result, the status of wolves across Asia is poorly documented, there is an enhanced risk of losing significant evolutionary lineages, and it detracts from research and conservation opportunities to preserve the entire carnivore guild. We propose various remedies, such as widening the scope of existing conservation programs, building awareness and knowledge of communities and law enforcement agencies, and more research to inform conservation and legislation.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13094","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143871601","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}

Amid an ever-growing maritime industry, we researched the performance of mobile underwater passive acoustic gliders as near real-time monitoring assets for the purpose of whale-vessel strike mitigation through dynamic management. Across 580 glider survey days, 30 near real-time acoustic detections of critically endangered North Atlantic right whales (NARWs) triggered 194 days of mandatory 10-knot vessel speed limits in three Canadian Dynamic Shipping Zones (DSZs). We found a high degree of interannual and seasonal variation in NARW acoustic occurrence and vessel slowdowns in the DSZs. Gliders were more effective than aerial surveillance at triggering slowdowns by a factor of 2–5 during fall and summer but were less effective during spring. Our results provide unambiguous evidence that gliders are effective monitoring platforms that can enhance dynamic ocean management goals globally.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13102","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857087","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}

Effective wildlife trade governance is critical for conservation and requires international cooperation and coordination to regulate an industry valued at hundreds of billions of dollars a year. Yet, due to increasing polarization over consumptive wildlife use, certain countries have become disenfranchised by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the primary mechanism for regulating international wildlife trade. Tensions within CITES are rising over the elephant ivory and rhino horn trade, where polarization has pushed ten Southern African Development Community countries to suggest an outright withdrawal from CITES. The denunciation of CITES by such a large and ecologically significant bloc would substantially weaken the integrity, credibility, and stature of the Convention. There is a contemporary precedent to reference: Japan left the International Whaling Commission (IWC) in 2019 due to polarization over commercial whaling. Here, we examine the common threads between these two cases: changing organizational ethos, polarization amongst members, influence of non-state actors, and loss of decidability for dissenting nations. Taking critical lessons from Japan's IWC withdrawal, we propose various options for structural reforms in CITES to restore decidability, enable equitability, and implement inclusive decision-making.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13099","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857086","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}

Here, we show how indigenous farmers conserve the genetic diversity of a farmed fish species—the common carp (Cyprinus carpio), locally known as paddy field carp (PF-carp)—within the paddy ecosystem. The PF-carp have been cocultured with rice in paddy fields (i.e., rice-fish coculture) by multiethnic farmers for thousands of years in southwestern China. Although converging to a similar morphological shape as an adaptation to the paddy ecosystem, PF-carp have diverged into diverse phenotypes, displaying high genetic diversity and a distinct genetic structure pattern. Farmers from different ethnic groups showed distinct preferences for fish, resulting in phenotypic diversity and genetic variation. A large number of multiethnic farmers participated in fish propagation, thereby maintaining a high level of genetic diversity in PF-carp. Our results highlight the critical role of indigenous farmers in preserving local genetic diversity and mitigating genetic degradation.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857088","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}

We present an approach to AM based in management strategy evaluation, a method used largely in fisheries. Managers define objectives and nominate alternative adaptive strategies, whose future performance is simulated by integrating ecological, learning and decision processes. We applied this approach to conservation of hihi (Notiomystis cincta) across Aotearoa-New Zealand. For multiple extant and prospective hihi populations, we jointly simulated demographic trends, monitoring, estimation, and decisions including translocations and supplementary feeding. Results confirmed that food supplementation assisted recovery, but was more intensive and expensive. Over 20 years, actively pursuing learning, for example by removing food from populations, provided little benefit. Recovery group members supported continuing current management or increasing priority on existing populations before reintroducing new populations. Our simulation-based approach can complement formal optimization-based approaches and improve AM uptake, particularly for programs involving many complex and coordinated decisions.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749560","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 lack of consensus can influence conservation outcomes in several ways. Conflict can arise between stakeholders with different definitions of stewardship; managers may not proactively identify important stakeholders whose stewardship orientation does not include public advocacy; and stakeholders whose sense of stewardship does not include in-depth knowledge of a particular ecosystem may advocate for ineffective or counterproductive actions. Developing strategies for identifying the implicit, unspoken definitions of environmental stewardship held by resource users, managers, and scientists can help with navigating these challenges. Here, we develop a method to elicit the unstated stewardship orientations of a group of stakeholders in a shared conservation setting. Using thought experiments and a Policy Delphi process, we find that even within our relatively homogeneous test group of recreational fisheries managers and scientists, individuals differed in their understanding of stewardship. We encourage conservation organizations with a mission of stewardship, or ones that interface with environmental stewards, to adopt an approach like this one to identify potential sources of conflict, inequity, and ineffective action before they arise.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660448","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}

Global research and policy attention on international wildlife trade has increased in recent years and is represented in key global policy frameworks (e.g., Kunming–Montreal Global Biodiversity Framework). Yet the dominant focus of research and discussion is on illegal wildlife trade and the use of CITES in managing trade for a subset of species, despite the fact that the majority of species in trade are legal and fall outside the remits of CITES. Furthermore, there is no global mechanism to record what species are traded; current systems only capture subsets of species and regions, with no consistent standards. This hampers our understanding of global trade patterns and limits any understanding of the wider sustainability of international wildlife trade. There is an urgent need to develop and implement policies that capture the full scope of international trade, tools that embed comprehensive and reproducible sustainability assessments, and funding that reflects the telecoupled nature of trade and the inherent wealth imbalance between exporting and importing nations. The adoption of these more holistic approaches is critical for a sustainable future for species in trade and the livelihoods reliant on them.","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 2","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660488","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}
