尽管在了解全球生物多样性丧失方面取得了实质性进展，但在分类学和地理知识方面仍存在重大差距。决策者通常依靠专家判断来填补知识空白，但很少能够与足够大和多样化的专家群体接触。为了更好地理解全球成千上万的生物多样性专家的观点，我们进行了一项调查，并要求专家们关注他们最熟悉的分类群和淡水、陆地或海洋生态系统。我们发现了一些压倒性的共识（例如，生物多样性丧失的多种驱动因素相互协同作用）和专家观点和估计中重要的人口和地理差异。来自生物多样性科学中代表性不足的群体的专家，包括妇女和来自全球南方的专家，为保护解决方案推荐了不同的优先事项，不太强调获得新的保护区，并提供了更高的生物多样性丧失及其影响的估计。这可能部分是因为他们不成比例地研究最受威胁的分类群和栖息地。环境科学学报；
Despite substantial progress in understanding global biodiversity loss, major taxonomic and geographic knowledge gaps remain. Decision makers often rely on expert judgement to fill knowledge gaps, but are rarely able to engage with sufficiently large and diverse groups of specialists. To improve understanding of the perspectives of thousands of biodiversity experts worldwide, we conducted a survey and asked experts to focus on the taxa and freshwater, terrestrial, or marine ecosystem with which they are most familiar. We found several points of overwhelming consensus (for instance, multiple drivers of biodiversity loss interact synergistically) and important demographic and geographic differences in specialists’ perspectives and estimates. Experts from groups that are underrepresented in biodiversity science, including women and those from the Global South, recommended different priorities for conservation solutions, with less emphasis on acquiring new protected areas, and provided higher estimates of biodiversity loss and its impacts. This may in part be because they disproportionately study the most highly threatened taxa and habitats.Front Ecol Environ2022;
