Wolf-dog hybridisation (WDH) - a form of anthropogenic introgressive hybridisation - may have occasionally occurred since the times of domestication. More recently, however, despite the ongoing recovery of wolf populations in Europe, the high number of domestic dogs along with marginal ecological conditions may pose increased risks to their genetic integrity. Accordingly, WDH is currently recognised among the highest threats to European wolves, with potential cascading effects through socio-ecological systems. Based on high quality DNA from tissues of 748 wolves retrieved dead from 2020 to 2024, alongside 26 additional samples from 1993 to 2003, we assessed WDH in the peninsular Italian wolf population. Using 23 autosomal STR loci and 5 Y-linked loci for males, we detected a high proportion (46.7 %) of wolves admixed with dogs, 29.5 % of which recent hybrids and 17.2 % older backcross generations. While most of the original hybridisation events likely took place some 9–16 years ago, a few first-generation hybrids in our sample indicate that WDH is currently ongoing. This seriously threatens the genetic integrity not only of the Italian wolf population, but also of the neighbouring wolf populations through dispersal events. The situation we present, which has not been previously reported for any wolf population worldwide, serves as a cautionary example of the potential dynamics of WDH in human-dominated landscapes should the issue remain persistently unaddressed. They also highlight the importance of considering the genetic constituency of wolf populations when evaluating their conservation status, especially in light of the recent downgrading of their protection status across Europe.
狼狗杂交(WDH)是一种人为的渐进式杂交,自驯化时代以来可能偶尔发生。然而,最近,尽管狼的数量在欧洲持续恢复,但大量的家养狗以及边缘生态条件可能对其遗传完整性构成更大的风险。因此,WDH目前被认为是欧洲狼面临的最大威胁之一,并可能通过社会生态系统产生连锁效应。基于从2020年至2024年检索到的748只狼的尸体组织中提取的高质量DNA,以及1993年至2003年的26个额外样本,我们评估了意大利半岛狼种群的WDH。利用23个常染色体STR位点和5个雄性y连锁位点,我们检测到狼与狗杂交的比例很高(46.7%),其中29.5%为近期杂交,17.2%为较老的回交代。虽然大多数原始杂交事件可能发生在大约9-16年前,但我们样本中的一些第一代杂交表明WDH目前正在进行中。这不仅严重威胁到意大利狼种群的遗传完整性,而且通过分散事件也威胁到邻近狼种群的遗传完整性。我们所呈现的情况,以前从未报道过世界范围内任何狼种群的情况,可以作为人类主导的景观中WDH潜在动态的一个警示例子,如果这个问题仍然没有得到解决。他们还强调了在评估狼种群的保护状况时考虑其遗传成分的重要性,特别是考虑到最近整个欧洲狼的保护地位降级。

Designing successful, equitable, and just marine protected areas (MPAs) requires integrated consideration of ecological, socioeconomic, and governance dimensions. Such an integrative approach to MPA design is critical as countries establish more MPAs in line with the 30 × 30 initiative. We reviewed and synthesised 574 design guidelines across 62 peer-reviewed and grey literature publications to assess the extent to which ecological, socioeconomic, and/or governance guidelines are integrated in current MPA design. We identified a total of 26 broad guidelines (i.e., 9 ecological, 12 socioeconomic, and 5 governance) across a variety of MPA objectives. We found that documents that included only ecological guidelines were the most frequently used (60 %), followed by socioeconomic (3 %) and governance guidelines (3 %). Almost 20 % of the documents combined ecological guidelines with socioeconomic guidelines, while only 8 % combined ecological guidelines with governance guidelines. Fewer than 7 % of documents combined all three to achieve MPA objectives. Adequacy often co-occurs with Connectivity, Comprehensiveness, and/or Ecological Importance among the ecological guidelines. Similarly, Equity frequently co-occurs with Cultural Identity and/or Social Context in papers reporting socioeconomic guidelines. Such a pattern could not be established for governance guidelines due to the low number of documents with governance guidelines. While our results reveal an imbalance and a lack of integrative MPA design, with the prevailing MPA design guidelines being ecologically driven, our synthesis of MPA design guidelines across different MPA objectives provides opportunities for integrating these guidelines towards a holistic MPA design that benefits both nature and people.
设计成功、公平和公正的海洋保护区(MPAs)需要综合考虑生态、社会经济和治理方面的因素。随着各国根据30 × 30倡议建立更多的海洋保护区,这种综合的海洋保护区设计方法至关重要。我们回顾并综合了62篇同行评审和灰色文献出版物中的574条设计指南,以评估生态、社会经济和/或治理指南在当前MPA设计中的整合程度。我们在各种MPA目标中确定了总共26个广泛的指导方针(即9个生态,12个社会经济和5个治理)。我们发现,仅包含生态指南的文件使用频率最高(60%),其次是社会经济指南(3%)和治理指南(3%)。近20%的文件将生态指导方针与社会经济指导方针相结合,而只有8%的文件将生态指导方针与治理指导方针相结合。只有不到7%的文件结合了这三种方法来实现MPA目标。在生态指引中,充分性通常与连通性、全面性和/或生态重要性同时出现。同样,在报告社会经济指导方针的论文中,公平经常与文化认同和/或社会背景共同出现。由于具有治理指导方针的文档数量很少,因此无法为治理指导方针建立这样的模式。虽然我们的研究结果表明,由于现行的MPA设计指导方针是以生态为导向的,因此存在不平衡和缺乏综合性MPA设计,但我们对不同MPA目标的MPA设计指导方针的综合研究,为将这些指导方针整合成有利于自然和人类的整体MPA设计提供了机会。

Conservation measures in protected areas are important for conserving global biodiversity. Despite the importance of assessing the effectiveness of protected areas and whether they develop toward their conservation goals, targeted monitoring programs in protected areas at the national level are rare. In Switzerland, a long-term program was launched in 2011 to systematically monitor changes in biodiversity and habitat quality in protected areas of national importance. Here, we focused on protected grasslands (0.7 % of Switzerland's surface area) and examined the status and changes of plot-level indicators over six years using a probability sample of 441 grassland sites (2149 vegetation plots) across Switzerland. We analyzed changes in vascular plant species richness, the proportions of threatened, specialized and neophyte species, environmental conditions (by means of ecological indicator values) and area of target vegetation types, and the factors associated with these indicators. Within six years, we detected a decreasing mean indicator value for nitrogen, an increasing proportion of specialist species and a significant decrease in area of non-target vegetation that developed toward the target vegetation, namely positive trends from a nature conservation perspective. However, thermophilization indicates climate-warming driven vegetation shifts. Our findings highlight the importance of well-replicated and standardized data in monitoring programs to evaluate temporal changes, which in our case enabled us to detect trends within a rather short period. The positive developments reflect successful nature conservation management by the federal and cantonal (= regional) authorities, which were implemented by farmers and nature conservation organizations by maintaining and promoting low-intensive land-use regimes.
保护区保护措施对保护全球生物多样性具有重要意义。尽管评估保护区的有效性以及它们是否朝着保护目标发展很重要,但在国家层面上对保护区进行有针对性的监测项目却很少。在瑞士,2011年启动了一个长期项目,系统地监测国家重要保护区生物多样性和栖息地质量的变化。在这里,我们重点关注受保护的草原(占瑞士表面积的0.7%),并使用瑞士441个草地点(2149个植被样地)的概率样本,检查了6年来样地水平指标的状态和变化。分析了维管植物物种丰富度、受威胁物种、特化物种和新生物种比例、环境条件(通过生态指标值)、目标植被类型面积的变化及其相关因子。6年间,氮素平均指标值呈下降趋势,专科物种比例呈上升趋势,非目标植被面积呈显著减少趋势,向目标植被方向发展,从自然保护的角度看,这是一个积极的趋势。然而,热干化表明气候变暖驱动的植被转移。我们的研究结果强调了在评估时间变化的监测程序中充分复制和标准化数据的重要性,在我们的案例中,这使我们能够在相当短的时间内发现趋势。这些积极的发展反映了联邦和州(=地区)当局成功的自然保护管理,这些管理是由农民和自然保护组织通过维持和促进低集约土地使用制度来执行的。

Species interactions are a key component of biodiversity; frugivore interactions drive tree population dynamics and landscape connectivity, especially in tropical forests. Here, we quantify the effects of anthropogenic factors on interaction diversity in forests across Gabon, accounting for natural environmental variation. Using data from 252 1-ha botanical plots and frugivory interaction data among 153 frugivore species with distributions in Gabon, we (i) assess the relationship between frugivory syndrome—i.e., whether or not a tree has fruits that are consumed by animals—and contribution to tree taxonomic and phylogenetic β diversity, (ii) quantify the effects of environmental variables on interaction diversity, and (iii) investigate anthropogenic effects as drivers of frugivory syndrome, as well as the richness, α diversity, local contribution to β diversity, and evolutionary distinctiveness of interactions. Frugivore interactions were predominant across Gabon; 84%–85% of individual trees were frugivore trees. Frugivore trees made greater contributions to tree β diversity across Gabon than trees without frugivore interactions, suggesting the importance of frugivory for maintaining regional biodiversity through seed dispersal services. Anthropogenic effects were associated with interaction richness, α diversity, and β diversity, but not evolutionary distinctiveness. While forest plots in areas of higher population density tended to have lower interaction richness and α diversity, they tended to make more contributions to national β diversity. However, the opposite was true for plots closer to villages. Overall, our findings provide new insights into the role of humans in frugivore interaction diversity; different anthropogenic effects have varied and nuanced impacts on interaction diversity.
物种相互作用是生物多样性的重要组成部分;果食性相互作用驱动树木种群动态和景观连通性,特别是在热带森林中。在这里,我们量化了人为因素对加蓬森林相互作用多样性的影响,并考虑了自然环境变化。利用来自252个1公顷植物样地的数据和分布在加蓬的153种果实相互作用数据,我们(i)评估了果实综合征(即:(ii)量化环境变量对相互作用多样性的影响;(iii)研究作为果食综合征驱动因素的人为影响,以及相互作用的丰富度、α多样性、局部对β多样性的贡献和进化特异性。果食性相互作用在加蓬占主导地位;84% ~ 85%的单株为果实树。在加蓬,果实树对树β多样性的贡献大于没有果实树相互作用的树,这表明果实树通过种子传播服务对维持区域生物多样性的重要性。人为效应与互作丰富度、α多样性和β多样性相关,但与进化独特性无关。种群密度较高地区的样地相互作用丰富度和α多样性较低,但对国家β多样性的贡献较大。然而,离村庄更近的地块情况正好相反。总的来说,我们的发现为人类在食果动物相互作用多样性中的作用提供了新的见解;不同的人为影响对相互作用的多样性有不同的、细微的影响。

Globally, diverse natural resource management initiatives have been undertaken to redress anthropogenic induced environmental change, including restoring natural habitats and adopting more sustainable land and agricultural practices. This paper blends knowledge across studies to learn more about the factors that contribute to, or detract from, their ecological ‘success’. We focus on natural resource management initiatives that involve a blend of formally constituted programs, informed by scientists, managed by various organisations, and implemented by practitioners and volunteers. We conduct a systematic search and analysis of relevant literature, identifying studies that seek to reveal or measure factors that influence the outcomes of these types of initiatives. We find two parallel, albeit somewhat disconnected strands of research: biophysical and socio-economic investigations. They conceptualise and measure success in different ways and thus identify different factors that contribute to success – using vastly different analytical approaches. Whilst the separation of biophysical and socio-economic investigations prevents us from undertaking a quantitative meta-analysis, by qualitatively blending insights from those bodies of work, we are able to identify a likely pathway from socioeconomic drivers to ecological successes. This pathway highlights that positive environmental change requires both social and ecological successes. There is a marked need for more research that genuinely integrates socio-economic and biological sciences to collect and analyse multidisciplinary data that generates empirical insights for further policy improvement.
在全球范围内,已采取各种自然资源管理倡议,以纠正人为引起的环境变化,包括恢复自然生境和采用更可持续的土地和农业做法。这篇论文混合了不同研究的知识,以更多地了解促进或损害其生态“成功”的因素。我们专注于自然资源管理项目,包括由科学家提供信息、由不同组织管理、由从业者和志愿者实施的一系列正式项目。我们对相关文献进行了系统的搜索和分析,确定了那些试图揭示或衡量影响这些类型的倡议结果的因素的研究。我们发现了两个平行的,尽管有些脱节的研究方向:生物物理和社会经济研究。他们以不同的方式概念化和衡量成功,从而识别出促成成功的不同因素——使用截然不同的分析方法。虽然生物物理和社会经济调查的分离使我们无法进行定量荟萃分析,但通过定性地融合这些工作机构的见解,我们能够确定从社会经济驱动因素到生态成功的可能途径。这条路径强调,积极的环境变化需要社会和生态的成功。明显需要更多真正整合社会经济和生物科学的研究,以收集和分析多学科数据,为进一步改善政策提供经验见解。

<div><div>With extinction risk for migratory species increasing globally, there is urgent need to safeguard the most important places used by migrants throughout their annual cycles. This requires prioritizing key sites and strengthening international collaboration and investment in less wealthy regions; yet progress has been limited by incomplete knowledge of how sites contribute to sustaining migratory populations and how sites are connected across seasons. Focusing on Mesoamerica's Five Great Forests (5GF) – the region's largest remaining and urgently threatened forests – we illustrate how information derived from the eBird participatory science platform can be used to assess the importance of nonbreeding sites for migratory birds and to identify “stewardship connections” between Mesoamerica and North America, based on abundance concentrations of shared species. We found that the 5GF support 20–46 % of the global populations of 16 Nearctic-Neotropical migratory species and ≥ 10 % of another 24 species outside of the breeding season. Key breeding grounds with stewardship connections to the 5GF include densely forested parts of the Northeastern U.S., Ontario and Québec, Minnesota and Wisconsin, the Mississippi Delta and Appalachian regions, and the Texas Hill Country. Our results provide evidence of the role of the 5GF as anchor points for migratory bird conservation and offer a powerful, data-driven communication tool to guide international investments and partnerships to protect these vital sites.

随着全球迁徙物种灭绝风险的增加,迫切需要保护迁徙者在其整个年度周期中使用的最重要的地方。这需要优先考虑关键地点,并加强在不太富裕地区的国际合作和投资;然而,由于不完全了解遗址如何有助于维持迁徙人口以及遗址如何跨季节连接,进展受到限制。以中美洲的五大森林(5GF)为例,我们展示了如何利用eBird参与式科学平台获取的信息来评估候鸟非繁殖地的重要性,并根据共享物种的丰度集中度确定中美洲和北美之间的“管理联系”。研究发现,5GF支持16种近北极-新热带候鸟种群的20 - 46%,支持24种非繁殖季节候鸟种群的≥10%。与5GF有管理联系的主要繁殖地包括美国东北部茂密的森林地区、安大略和quacimbec、明尼苏达州和威斯康星州、密西西比三角洲和阿巴拉契亚地区,以及德克萨斯山区。我们的研究结果为5GF作为候鸟保护锚点的作用提供了证据,并为指导保护这些重要地点的国际投资和合作提供了一个强大的、数据驱动的沟通工具。更广泛地说,我们展示了一种灵活的方法,利用参与式科学信息来确定共享物种群周围的跨境联系,目的是加快对候鸟栖息地的联合管理。ResumenCon el aumento del riesgo de extinción de las especitermigratora nialdial,存在必要的紧急情况,de proteigerlos lugares más importantes que utilizandlos migratora每年有大量的数量。Para ello是必要的优先事项,并由改革家网站colaboración国际网站inversión和各区域网站prósperas提供;在禁运期间,损失预付额超过了访问限制、贫穷的经济状况、不完整的捐款损失情况和对移徙者造成的潜在影响(cómo),这些损失情况每年都有相当大的数额。Centrándonos在中美洲的大样本(5GF)中,在中美洲的大样本(5GF)中,在中美洲的大样本(5GF)中,在中美洲的大样本(más大样本)中,在中美洲的大样本(región)中,在中美洲的大样本(región)中,在中美洲的大样本(región)中,在中美洲的大样本(región)中,在中美洲的大样本(región)中,在中美洲的大样本(cómo)中,在中美洲的大样本(cómo)中,在中美洲的大样本(cómo)中,在中美洲的大样本(cómo)中,在平台上的衍生样本(científica)参与性样本(参与性样本),在中美洲的大样本(cómo)中,在中美洲的大样本(basándonos)中,在中美洲的大样本(basándonos)中,在比较物种丰富的集中样本(basándonos)中。Descubrimos que los 5GF albergan entre el 20% y el 46% de las poblaciones mundiales de 16种候鸟neárticas-neotropicales y más de 10% de otras 24种候鸟reproducción。Las principales zone of reproducción con conexiones de manejo conlos 5GF包括Las zonas densamente boscoas de Estados Unidos, Ontario and Quebec, Minnesota and Wisconsin, el delta del mississippi, Las region of los Apalaches, la región de Texas Hill Country。《新结果》的结果是,我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:我们的研究结果是:在一般情况下,灵活的示范和示范将通过下述方式进行:información científica参与性的示范和示范将通过下述方式进行:跨国境的相同的示范和特别的比较者的示范,通过示范和示范的目的将通过gestión控制和hábitat移徙者的示范。

This requires prioritizing key sites and strengthening international collaboration and investment in less wealthy regions; yet progress has been limited by incomplete knowledge of how sites contribute to sustaining migratory populations and how sites are connected across seasons. Focusing on Mesoamerica's Five Great Forests (5GF) – the region's largest remaining and urgently threatened forests – we illustrate how information derived from the eBird participatory science platform can be used to assess the importance of nonbreeding sites for migratory birds and to identify “stewardship connections” between Mesoamerica and North America, based on abundance concentrations of shared species. We found that the 5GF support 20–46 % of the global populations of 16 Nearctic-Neotropical migratory species and ≥ 10 % of another 24 species outside of the breeding season. Key breeding grounds with stewardship connections to the 5GF include densely forested parts of the Northeastern U.S., Ontario and Québec, Minnesota and Wisconsin, the Mississippi Delta and Appalachian regions, and the Texas Hill Country. Our results provide evidence of the role of the 5GF as anchor points for migratory bird conservation and offer a powerful, data-driven communication tool to guide international investments and partnerships to protect these vital sites.

Due to land use and climate change, human-wildlife interactions rise, often leading to conflicts, especially when carnivores are involved. Understanding social perceptions of expanding carnivore species is crucial to reduce the associated potential conflicts. Through online surveys we assessed the perceptions of 232 hunters and 666 non-hunters regarding both the negative and positive impacts of the expanding Egyptian mongoose (Herpestes ichneumon) in central Spain, and we also evaluated respondents' familiarity with the species. We used the Potential Conflict Index to assess the degree of intra- and inter- group consensus (hunters and non-hunters) and to explore the effect of familiarity and information in driving conservation conflicts.
Hunters and non-hunters opinions diverged about the negative impacts of mongooses, namely for the ecosystems and rural economy. On the contrary, non-hunters were more likely to perceive mongoose as having beneficial impacts. Hunters' lowest consensus referred to the impact of potential mongoose attacks on livestock. In contrast, there was a high level of consensus among non-hunters regarding mongoose's contribution to biodiversity conservation, while the lowest consensus was related to its impact on attacking pets. We demonstrated that familiarity with a species by name or appearance may be a vague approximation of the level of information about the negative impacts and benefits derived from that species.
Our results suggest that ecological information campaigns as an effective tool to help mitigating conservation conflicts. Increasing residents' awareness (including hunters) about the species occurring in their territories, and explaining its effect on the ecosystems and rural livelihoods would be especially valuable for understudied expanding mesocarnivores.
由于土地利用和气候变化,人类与野生动物的互动增加,经常导致冲突,特别是当涉及食肉动物时。了解扩大食肉动物物种的社会观念对于减少相关的潜在冲突至关重要。通过在线调查,我们评估了232名猎人和666名非猎人对西班牙中部不断扩大的埃及猫鼬(Herpestes ichneuon)的负面和积极影响的看法,并评估了受访者对该物种的熟悉程度。我们使用潜在冲突指数来评估群体内和群体间的共识程度(猎人和非猎人),并探讨熟悉度和信息在驱动保护冲突中的作用。捕猎者和非捕猎者对猫鼬的负面影响(即对生态系统和农村经济的负面影响)的看法存在分歧。相反,非猎人更有可能认为猫鼬有有益的影响。猎人的最低共识是猫鼬可能袭击牲畜的影响。相比之下,非捕猎者对猫鼬对生物多样性保护的贡献有很高的共识,而对猫鼬对攻击宠物的影响的共识最低。我们证明,通过名称或外观熟悉一个物种可能是关于该物种的负面影响和收益的信息水平的模糊近似值。我们的研究结果表明,生态信息运动是帮助缓解保护冲突的有效工具。提高居民(包括猎人)对其领土上出现的物种的认识,并解释其对生态系统和农村生计的影响,对研究不足的不断扩大的中食肉动物尤其有价值。

Understanding how human activities influence wildlife populations is crucial for the conservation of endangered species, yet assessing their demographic impacts remains challenging. This is partly because experimental approaches are seldom feasible in research on threatened wildlife, limiting our ability to effectively identify and manage key threats. Here, we capitalized on an unintentional pseudo-experiment—the 2020 COVID-19 lockdown—embedded within a 31-year monitoring program (1246 breeding attempts from 1994 to 2024) of the endangered Bonelli's eagle subpopulation of southeastern Spain to assess the effects of human activities on its reproductive success. We detected a significant increase in productivity during the lockdown, especially in territories traditionally subject to a higher number of human activities. Partridge hunting with calling lures and traffic—likely facilitating other recreational uses such as hiking and cycling—were identified as the most detrimental activities for breeding success. This study demonstrates how exceptional events, when analyzed within a long-term framework, can uncover the full extent of human disturbance on wildlife, thereby helping to identify priority actions for conservation. It also underscores the limitations of purely correlational studies and highlights the irreplaceable value of long-term monitoring for understanding and mitigating threats to endangered species.
了解人类活动如何影响野生动物种群对濒危物种的保护至关重要,但评估其人口影响仍然具有挑战性。这部分是因为实验方法在濒危野生动物研究中很少可行,限制了我们有效识别和管理关键威胁的能力。在这里,我们利用了一个无意的伪实验——2020年COVID-19封锁——嵌入了一个为期31年的监测计划(1994年至2024年期间1246次繁殖尝试),对西班牙东南部濒临灭绝的博内利鹰亚群进行了监测,以评估人类活动对其繁殖成功的影响。我们发现,在封锁期间,生产力显著提高,特别是在传统上人类活动较多的地区。用召唤诱饵狩猎鹧鸪和交通——可能会促进其他娱乐用途,如徒步旅行和骑自行车——被认为是对繁殖成功最有害的活动。这项研究表明,当在长期框架内分析异常事件时,可以揭示人类对野生动物干扰的全部程度,从而有助于确定保护的优先行动。它还强调了纯相关性研究的局限性,并强调了长期监测对了解和减轻濒危物种威胁的不可替代的价值。

Since its inception as a crisis discipline, conservation biology has provided extensive theoretical insights into biodiversity protection. Yet, despite substantial growth in knowledge, navigating the spaces between theory and effective practice remains a persistent challenge. Through a comprehensive systematic review, we evaluate how scientific literature addressing habitat loss and degradation translates theoretical frameworks into practical applications. By categorising reviewed studies into distinct stages (“Knowing,” “Guidelines,” and “Doing”), we identify a pronounced dominance of theoretical contributions coupled with pronounced geographical, ecological, and taxonomic biases. Such biases significantly constrain the utility of existing conservation knowledge for policy-making and practical interventions. Although rich and valuable scientific data is abundant, translating this information into actionable, practical knowledge, crucially needed for informed policy decisions and effective conservation practice, remains inadequate. We advocate for an evidence-based, transdisciplinary approach emphasising active stakeholder participation, innovative communication strategies, and rigorous impact evaluations to address these critical gaps. Such an integrated framework promises to drive more equitable, practical, and actionable conservation outcomes worldwide.
自作为一门危机学科成立以来,保护生物学为生物多样性保护提供了广泛的理论见解。然而,尽管知识大幅增长,在理论和有效实践之间的空间导航仍然是一个持续的挑战。通过全面的系统回顾,我们评估了关于栖息地丧失和退化的科学文献如何将理论框架转化为实际应用。通过将回顾的研究分类为不同的阶段(“知道”、“指导”和“做”),我们确定了理论贡献的明显优势,以及明显的地理、生态和分类学偏见。这种偏见极大地限制了现有保护知识在决策和实际干预中的效用。尽管有丰富而有价值的科学数据,但将这些信息转化为可操作的实用知识仍然不足,而这些知识对于知情的政策决定和有效的保护实践至关重要。我们提倡以证据为基础的跨学科方法,强调利益相关者的积极参与、创新的沟通策略和严格的影响评估,以解决这些关键差距。这样一个综合框架有望在全球范围内推动更公平、实用和可操作的保护成果。
