土壤线虫的丰度和功能组的组成
Soil nematode abundance & functional group composition
作为地球上最丰富的动物，线虫是土壤群落的一个主要组成部分。它们在调节生物地球化学循环和植被动态方面发挥着关键作用，是土壤生物活动的一个指标。在这里，我们提出了一个全面的土壤线虫丰度和功能组组成的全球数据集。该数据集包括来自各大洲和生物群落的6825个地理坐标的土壤样本。出于地理空间绘图的目的，这些样本被汇总成1933个独特的1公里像素，每个像素都与73个全球环境协变量数据层相联系。这项研究使用了来自世界各地6825个地理坐标点的土壤线虫丰度的直接测量，涵盖了所有大陆和所有陆地生物群落。您可以在这里阅读该论文：
