The notion that introduced populations of cold-adapted species hold conservation value despite their non-native status remains controversial. Many such populations exist as a legacy of humans moving wildlife to novel environments with little true consideration of species conservation. Herein, we identify cases in which individuals from inadvertent climate refugia (ICR) are returned to formerly occupied ranges or used to augment declining native populations. While conservation benefits have been infrequently realized, the global distribution of ICR offers a potentially untapped resource. Lessening biodiversity loss under increasing climate challenges will likely require assisted migration of many species and necessitate novel valuation of extant introduced populations—such as those within ICR. While ecological costs of translocated species are widely known, we highlight how species moved generations ago to ICR offer a reservoir for reintroductions and a buffer against rapidly changing climates.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 6","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142436415","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, evaluating the effectiveness of large-scale community-based conservation interventions is rarely done, making it problematic to assess or justify their impact. In our study focused on snow leopards (<i>Panthera uncia</i>) in five countries, we show that bespoke and well-implemented community-based and conflict management intervention efforts can lead to more sustainable conservation outcomes. Collaborative interventions, spread over about 88,000 km² of snow leopard habitat, reduced livestock depredation and disease and associated economic costs. Additionally, they generated conservation-linked livelihoods and enhanced community decision-making, leading to more positive behavioral intent toward snow leopards and improved communities’ cooperation, economic security, and confidence. Our results provide lessons learned and recommendations for practitioners and governments to alleviate conflicts and foster coexistence with snow leopards and large carnivores more broadly.

For coral reefs, parrotfish protection emerged as a mainstream action for reversing the degradation experienced by these systems. The rationale is that restoring their populations will increase grazing activity and reinforce control of fast-growing macroalgae, facilitating coral cover recovery. A lack of a link between parrotfish trends and macroalgae and coral cover trends at a large scale has, however, often been the case. Suggesting more complex underlying dynamics that should be reexamined. In this review, we discuss how lumping parrotfish species as if they were functionally redundant may obscure trends. And how a lack of appreciation of other functions around the parrotfish paradigm, specifically bioerosion, may have unforeseen and potentially adverse effects on degraded reefs. We show that bioerosion responded more directly and quickly to spatial and temporal changes in parrotfish assemblages than macroalgae consumption, arguably due to the varying vulnerability among Caribbean parrotfishes to fisheries and habitat loss. For highly degraded reefs, positive changes in parrotfish populations could hence compromise the remaining coral skeleton structures and the reef framework, further accentuating reef degradation, where increases in macroalgae consumption could not necessarily compensate for higher rates of bioerosion.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 6","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142385036","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}

(&lt;span&gt;2024&lt;/span&gt;) recently argued that protecting red colobus deserves priority attention, serving as flagships of African tropical forest conservation strategies. We appreciate and support the authors’ efforts to build a plan to conserve red colobus and their habitats. In this correspondence, we provide a complementary perspective, arguing that conservation attention should be extended to diverse communities of various taxa rather than a single-species group.&lt;/p&gt;&lt;p&gt;Linder et al. (&lt;span&gt;2024&lt;/span&gt;) consider red colobus as barometers of African tropical forest health and hunting pressure. This generalization should be limited to the geographical range of red colobus and not applied to all African tropical forests, which are more extensive. In addition, although red colobus are threatened by gun hunting—a method that is increasingly used and severely impacts arboreal species—they cannot be considered barometers of other hunting pressures, such as snaring. Snare hunters vastly outnumber gun hunters in some regions of West and Central Africa (Fa &amp; Brown, &lt;span&gt;2009&lt;/span&gt;). They put considerable pressure on diverse wildlife communities across African tropical forests.&lt;/p&gt;&lt;p&gt;We advocate for a more equitable distribution of conservation attention across diverse taxa to develop conservation strategies that adequately represent the complexity of biodiversity and ecological functions. Diverse wildlife communities maintain the resilience of desirable ecosystem states (Elmqvist et al., &lt;span&gt;2003&lt;/span&gt;) and secure various ecosystem functions and services (Harrison et al., &lt;span&gt;2014&lt;/span&gt;). Thus, conservation strategies and priorities should be based on entire communities rather than focusing solely on individual species or genera. Focusing on a particular group of indicator species presenting specific ecological requirements oversimplifies complex ecosystems. This neglects the rich interactions among various wildlife species that must be preserved to maintain functioning ecosystems.&lt;/p&gt;&lt;p&gt;As an inspiration for mammals, Fonteyn et al. (&lt;span&gt;2023&lt;/span&gt;) identified six zoogeographic districts (or species assemblages) across central African forests, separately for carnivores, primates, and artiodactyls. Within the primate communities, red colobus are part of the significant indicator species of several biogeographical districts but should not be considered alone. The compilation of species lists from wildlife and bushmeat-related surveys allows for the assessment of the conservation status of each district and its ongoing threats. Compiled species lists constitute a valuable tool for assessing the presence or loss of individual species, providing guidance for long-term conservation programs.&lt;/p&gt;&lt;p&gt;Verschueren et al.

The footprint of the longline fishery spanned the entire exclusive economic zone of the Solomon Islands and was 67 times bigger than the footprint of the small-scale fishery. The median catch summed across both fisheries was ∼12,000 turtles in 2018, with 85%–97% of that catch in the small-scale fishery.

We propose to use the world's largest MPA in the Ross Sea, Antarctica as a model system to create a comprehensive framework for an interdisciplinary network supporting research and monitoring that could be implemented in other remote large-scale international MPAs. Our proposed framework has three key components: (i) policy engagement, including delineation of policy needs and ecosystem metrics to assess MPA effectiveness; (ii) community partner engagement to elevate diverse voices, build trust, and share resources; and (iii) integrated science comprising three themes. These themes are: advancement of data science and cyberinfrastructure to facilitate data synthesis and sharing; biophysical modeling towards understanding ecosystem changes and uncertainties; and execution of observational and process studies to address uncertainties and evaluate ecosystem metrics.

Managing this panzootic requires identification of transmission pathways. We investigated potential HPAIV transmission via kleptoparasitism (food theft) by examining the distribution, behaviors, and movements of two globally widespread and commonly kleptoparasitic seabird families: Fregatidae (frigatebirds) and Stercorariidae (skuas). These kleptoparasites force other seabirds (targets) to regurgitate food, which the kleptoparasite then ingests, potentially facilitating direct transfer of viral particles from target to kleptoparasite. Scavenging and predation probably contribute further to viral spread. Although frigatebirds use kleptoparasitism on a year-round basis, skuas more commonly do so outside of the breeding season. Both frequently forage, disperse, or migrate across oceans and hemispheres. Dense aggregations of kleptoparasitic and target seabirds at breeding and/or roosting sites may facilitate the spread of HPAIV. In addition, the migration of these species could also facilitate broadscale geographic spread of HPAIV. Surveillance of kleptoparasites for HPAIVs could aid in early detection and may be important for seabird conservation.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 6","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236632","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}

Specifically, a closer exchange between land-use data developers and users will enable common terminology and better data use, allowing to move beyond coarse land-cover representations of land use. Similarly, archetyping and regionalization approaches can help to embrace, rather than oversimplify, the diversity of land-use actors and practices. Finally, systematically linking land-use actors to portfolios of pressures on biodiversity, beyond their direct impact on habitat, can better represent and map co-occurring and interacting threats.
