不可持续的野生动物收获是对全球生物多样性和数百万依靠野生动物获得食物和收入的人的重大威胁。过去的研究已经引起了人们的注意，即常用的方法来评估野生动物狩猎的可持续性表现不佳，但这些方法仍然在今天流行的使用。在这里，我们对实证可持续性评估进行了系统的回顾，以量化科学文献中可持续性指标的使用，并突出分析方法及其结果之间的关联。我们发现，指标类型，研究大陆，物种体重，分类组和研究地点的社会经济地位是报告的可持续性概率的重要预测因素。最常见的可持续性衡量标准包括人口增长模型、罗宾逊和雷德福（1991年）模型和人口长期趋势。依赖特定人群生物数据的指标最常用于北美和欧洲，而非洲、拉丁美洲和大洋洲更常使用粗略估计数。我们的研究结果突出了可持续发展科学的不确定性和缺乏统一性。鉴于我们迫切需要保护野生动物和世界各地农村人民的粮食安全，改善可持续性指标至关重要。
The unsustainable harvest of wildlife is a major threat to global biodiversity and to the millions of people who depend on wildlife for food and income. Past research has called attention to the fact that commonly used methods to evaluate the sustainability of wildlife hunting perform poorly, yet these methods remain in popular use today. Here, we conduct a systematic review of empirical sustainability assessments to quantify the use of sustainability indicators in the scientific literature and highlight associations between analytical methods and their outcomes. We find that indicator type, continent of study, species body mass, taxonomic group and socio‐economic status of study site are important predictors of the probability of reported sustainability. The most common measures of sustainability include population growth models, the Robinson & Redford (1991) model and population trends through time. Indicators relying on population‐specific biological data are most often used in North America and Europe, while cruder estimates are more often used in Africa, Latin America and Oceania. Our results highlight both the uncertainty and lack of uniformity in sustainability science. Given our urgent need to conserve both wildlife and the food security of rural peoples around the world, improvements in sustainability indicators are of utmost importance.
