Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross-biome survey including 83 locations across six continents to advance our understanding of the ecological preferences and vulnerabilities of the diversity of dominant and functionally important soil invertebrate taxa, including nematodes, arachnids and rotifers. The diversity of invertebrates was analyzed through amplicon sequencing. Vegetation and climate drove the diversity and dominant taxa of soil invertebrates. Our results suggest that declines in forest cover and plant diversity, and reductions in plant production associated with increases in aridity, can result in reductions of the diversity of soil invertebrates in a drier and more managed world. We further developed global atlases of the diversity of these important soil invertebrates, which were cross-validated using an independent database. Our study advances the current knowledge of the ecological preferences and vulnerabilities of the diversity and presence of functionally important soil invertebrates in soils from across the globe. This information is fundamental for improving and prioritizing conservation efforts of soil genetic resources and management policies.

生物群落中无脊椎动物的气候脆弱性和生态偏好。

与植物和脊椎动物不同，在全球陆地生态系统中，人们对土壤无脊椎动物的生态偏好和潜在脆弱性对环境变化的了解仍然很少。我们在六大洲的83个地点进行了跨生物组的调查，以加深我们对优势和功能重要的土壤无脊椎动物类群（包括线虫，蜘蛛和轮虫）的生态偏好和脆弱性的了解。通过扩增子测序分析无脊椎动物的多样性。植被和气候驱动着土壤无脊椎动物的多样性和优势类群。我们的结果表明，森林覆盖率和植物多样性的下降以及与干旱增加相关的植物产量的下降，可能会导致在干燥且管理更加完善的世界中无脊椎动物的多样性减少。我们进一步开发了这些重要土壤无脊椎动物多样性的全球地图集，并使用独立的数据库对其进行了交叉验证。我们的研究提高了当前对全球各地土壤中的生态偏好和脆弱性以及功能重要的土壤无脊椎动物的多样性的认识。该信息对于改善和优先考虑土壤遗传资源和管理政策的保护工作至关重要。我们的研究提高了当前对全球各地土壤中的生态偏好和脆弱性以及功能重要的土壤无脊椎动物的多样性的认识。该信息对于改善和优先考虑土壤遗传资源和管理政策的保护工作至关重要。我们的研究提高了当前对全球各地土壤中的生态偏好和脆弱性以及功能重要的土壤无脊椎动物的多样性的认识。该信息对于改善和优先考虑土壤遗传资源和管理政策的保护工作至关重要。
