Abstract：
Reptiles are an important, yet often understudied, taxon in nature conservation. They play a significant role in ecosystems1 and can serve as indicators of environmental health, often responding more rapidly to human pressures than other vertebrate groups.2 At least 21% of reptiles are currently assessed as threatened with extinction by the IUCN.3 However, due to the lack of comprehensive global assessments until recently, they have been omitted from spatial studies addressing conservation or spatial prioritization (e.g., Rosauer et al.,4,5,6,7,8 Fritz and Rahbek,4,5,6,7,8 Farooq et al.,4,5,6,7,8 Meyer et al., 4,5,6,7,8 and Farooq et al.4,5,6,7,8). One important knowledge gap in conservation is the lack of spatially explicit information on the main threats to biodiversity,9 which significantly hampers our ability to respond effectively to the current biodiversity crisis.10,11 In this study, we calculate the probability of a reptile species in a specific location being affected by one of seven biodiversity threats-agriculture, climate change, hunting, invasive species, logging, pollution, and urbanization. We conducted the analysis at a global scale, using a 50 km × 50 km grid, and evaluated the impact of these threats by studying their relationship with the risk of extinction. We find that climate change, logging, pollution, and invasive species are most linked to extinction risk. However, we also show that there is considerable geographical variation in these results. Our study highlights the importance of going beyond measuring the intensity of threats to measuring the impact of these separately for various biogeographical regions of the world, with different historical contingencies, as opposed to a single global analysis treating all regions the same.
摘要：
爬行动物是一个重要的，但经常被研究不足，自然保护中的分类单元。它们在生态系统中起着重要的作用1，可以作为环境健康的指标，通常比其他脊椎动物对人类压力的反应更快。2目前，至少有21％的爬行动物被评估为濒临灭绝的威胁。由于直到最近还缺乏全面的全球评估，在解决保护或空间优先次序的空间研究中省略了它们(例如，Rosauer等人。,4,5,6,7,8弗里茨和拉贝克,4,5,6,7,8Farooq等人。,4,5,6,7,8Meyer等人。,4,5,6,7,8和Farooq等4,5,6,7,8)。保护方面的一个重要知识差距是缺乏关于生物多样性主要威胁的空间明确信息，9，这显著阻碍了我们有效应对当前生物多样性危机的能力。10,11在这项研究中，我们计算了特定位置的爬行动物物种受到七种生物多样性威胁之一-农业影响的概率，气候变化,狩猎,入侵物种,测井,污染,和城市化。我们在全球范围内进行了分析，使用50公里×50公里的网格，并通过研究它们与灭绝风险的关系来评估这些威胁的影响。我们发现气候变化，测井,污染,入侵物种与灭绝风险联系最大。然而,我们还表明，这些结果存在相当大的地理差异。我们的研究强调了超越衡量威胁强度的重要性，以衡量这些威胁对世界各个生物地理区域的影响。在不同的历史偶然性下，而不是单一的全球分析对待所有地区都一样。
