Soil protists are an essential yet seriously understudied component of the soil microbiome. In this study, 11 new records of dictyostelids belonging to 2 orders, 3 families, and 4 genera were identified from 99 soil samples collected from different elevations and habitats in central Gansu and the southeastern and southcentral portions of Guizhou Province, China. We found that dictyostelid communities were significantly different between Gansu and Guizhou Provinces, apparently in response to different environmental factors. Moreover, dictyostelids were found to have the highest species diversity in mixed forests. Soil pH, temperature, and elevation were determined to be the primary factors that affect the distribution and occurrence of dictyostelids in Guizhou and Gansu Provinces. This work supplements the survey data available for dictyostelids elsewhere in China. These new findings have significant implications for our understanding of the diversity of soil microorganisms.
土壤原生动物是土壤微生物组中一个必不可少但研究严重不足的组成部分。在这项研究中，从中国甘肃中部、贵州东南部和中南部不同海拔和生境采集的 99 个土壤样本中，鉴定出属于 2 个目、3 个科和 4 个属的 11 种新的粘菌记录。我们发现甘肃和贵州两省的粘菌群落有明显的差异，显然是对不同环境因素的响应。此外，粘菌在混交林中具有最高的物种多样性。土壤 pH 值、温度和海拔被确定为影响贵州和甘肃两省粘菌分布和发生的主要因素。这项工作补充了中国其他地区粘菌的调查数据。这些新发现对我们理解土壤微生物多样性具有重要意义。
