{"title":"Use Real-Time Mortality Alerts to Save Vultures","authors":"Andrea Santangeli","doi":"10.1111/con4.70031","DOIUrl":"10.1111/con4.70031","url":null,"abstract":"<p>Poisoning is the leading threat to vultures and other scavengers worldwide, and its scale has grown alarmingly in the past decades (Plaza et al. <span>2019</span>). From January 2000, nearly 41,000 wildlife deaths from poisoning have been reported in Africa alone, almost half involving threatened vultures (The Endangered Wildlife Trust and the Peregrine Fund <span>n.d</span>.). Strikingly, more than 8000 wildlife mortalities have been reported since 2020 alone, with over 6600 vultures among them. The mass poisoning in Guinea–Bissau in 2020, which killed more than 2000 Critically Endangered hooded vultures (<i>Necrosyrtes monachus</i>; Henriques et al. <span>2020</span>), was followed by many other incidents. These include the recent loss of over 100 vultures in Kruger National Park, South Africa (May 2025; Vulture Conservation Foundation <span>2025</span>). Similar events across South America, Europe, and Asia show that few safe havens remain for these keystone species (Plaza et al. <span>2019</span>). Without urgent, innovative action, we risk losing vultures—and the essential ecosystem services they provide (Santangeli et al. <span>2024</span>). So far, we appear to be losing the battle against the perpetrators of this illicit and indiscriminate practice (Ogada et al. <span>2016</span>; Margalida et al. <span>2019</span>). While education, legislation, and community engagement are essential to addressing the root causes of vulture poisoning, these measures typically yield results only in the medium to long term. What is urgently needed are evidence-based, immediate interventions to reduce mortalities. Rapid response teams capable of decontaminating poisoning sites can save many vultures’ lives (Murn and Botha <span>2018</span>). However, their effectiveness is limited to the few events that are timely detected. Tragically, most incidents go unnoticed or are discovered far too late, as exemplified by the Guinea–Bissau massacre of 2020.</p><p>Rapid advances in biologging offer a powerful tool to combat poisoning and other wildlife crimes. This is particularly operationalized by fitting animals with GPS units and following their movement and behavior, which can eventually indicate the where and when of a specific incidence type under focus. Death detector algorithms in GPS-tracked birds can now send near-live mortality alerts via GSM and/or satellite. Moreover, the falling cost of transmission, driven by newly developed and developing systems, such as ICARUS satellite transmission (to be launched in 2026), makes large-scale deployments feasible, affordable, and reliable, especially in the near future (Kays and Wikelski <span>2023</span>). The ICARUS system will be particularly valuable in areas without GSM coverage, where poisoning events might otherwise go undetected due to phone-based transmission gaps. By enabling satellite-based data transfer, ICARUS can ensure that mortality alerts are received even from the most remote regions.

We conducted a multidimensional analysis of climate-change vulnerability for National Parks to identify which parks are most at risk of climate-change impacts and therefore in the greatest need of targeted climate-change vulnerability assessment and planning. We identified 174 (67%) parks as most exposed to one or more potentially transformative climate impacts including fire, drought, sea-level rise, and forest pests and diseases. Cumulative vulnerability across multiple dimensions was the highest for parks in the Midwest and eastern United States due to high physical exposures, the exacerbation of existing stressors, and high surrounding land-use intensity. Western parks exhibited lower cumulative vulnerability due to less intense land use and topography that may provide climatic refugia. However, western parks tended to be most exposed to multiple transformative impacts. These widespread, diverse threats highlight not only the need for coordinated evaluation of vulnerabilities from multiple perspectives, but also the need for park managers to evaluate and plan for potentially irreversible ecological changes to the landscapes and resources that parks are intended to preserve.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://conbio.onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146215666","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 identify an additional form of risk for biodiversity: The risk that legal protections may be scaled back or repealed as a result of political changes. We demonstrate the importance of “political extinction risk” through an analysis of the implications of a partial repeal of the federal Endangered Species Act, removing protections for species on private lands. Such a repeal reduces protections for all species from hunting by over one-third, and from habitat modification by over 40%. Loss of protections vary significantly by species, across states, and by taxonomic group. In particular, more charismatic taxonomic groups generally have higher levels of protection relative to less charismatic groups.

One important question concerns whether legal protection can be phased out once a species is considered recovered and how this affects population dynamics. We used Bayesian hierarchical models and time series of annual population size estimates for gray wolves (<i>Canis lupus</i>) across eight US states to assess how annual population growth rates were affected by the proportion of each year that each wolf population was not listed under the ESA. We found that between 1979 and 2022, delisting had an overall negative effect on the growth rate of wolf populations. This effect remained after accounting for potential confounders like density dependence. The resulting growth rates after 1 year unlisted varied between the different states’ populations and included short-term declines as well as population stabilization and continued growth at slower rates over longer terms.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://conbio.onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146169566","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}

Achieving these goals requires protecting not only species and habitats but also the networks of biotic interactions that sustain them. Food webs, which represent predator-prey interactions between species, are increasingly recognised as a link between ecosystem structure, function, and resilience, which are concepts that are frequently cited in conservation policy. Yet, conservation planning and policy typically focus on individual species and habitats and overlook the interactions that support their persistence. We review the literature at the intersection of food web ecology and conservation, and highlight how food webs can inform three conservation goals: preventing species extinctions, maintaining ecosystem functions and NCP, and fostering ecosystem resilience. Food web data and metrics, such as interaction diversity, trophic diversity, connectance, or modularity, can be used to prioritize species that are key to ecosystem structure and functioning, and to guide spatial prioritization to protect functionally diverse and resilient communities. Given the growing availability of food web data, incorporating food webs in conservation planning can lead to more effective and resilient conservation outcomes that sustain biodiversity and ecosystem functions in the long term.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"19 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://conbio.onlinelibrary.wiley.com/doi/epdf/10.1111/con4.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146153368","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}
