Soil degradation can have an impact on the soil microbiota, but its specific effects on soil fungal communities are poorly understood. In this work, we studied the impact of soil degradation on the richness and diversity of communities of soil fungi, including three different degrees of degradation in Germany and Panama. Soil fungi were isolated monthly using the soil-sprinkling method for 8 months in Germany and 3 months in Panama, and characterized by morphological and molecular data. Soil physico-chemical properties were measured and correlated with the observed values of fungal diversity. We isolated a total of 71 fungal species, 47 from Germany, and 32 from Panama. Soil properties were not associated with fungal richness, diversity, or composition in soils, with the exception of soil compaction in Germany. The geographic location was a strong determinant of the soil fungal species composition although in both countries there was dominance by members of the orders Eurotiales and Hypocreales. In conclusion, the results of this work do not show any evident influence of soil degradation on communities of soil fungi in Germany or Panama.
土壤退化会对土壤微生物群产生影响，但其对土壤真菌群落的具体影响却鲜为人知。在这项研究中，我们研究了土壤退化对土壤真菌群落丰富度和多样性的影响，研究涵盖了德国和巴拿马的三种不同程度的退化情况。在德国，每月使用土壤喷洒法分离土壤真菌，持续8个月；在巴拿马则持续3个月，然后通过形态学和分子数据对分离出的真菌进行特征描述。测量了土壤理化性质，并将其与观察到的真菌多样性值进行关联分析。我们总共分离出71种真菌，其中47种来自德国，32种来自巴拿马。除了德国的土壤压实情况外，土壤性质与土壤中真菌的丰富度、多样性或组成并无关联。地理位置是土壤真菌物种组成的一个重要决定因素，尽管在这两个国家，曲霉目和肉座菌目的成员都占主导地位。总之，这项研究结果并未显示出土壤退化对德国或巴拿马的土壤真菌群落有任何明显影响。
