Understanding the interactions among microbial communities, plant communities and soil properties following deforestation could provide insights into the long-term effects of land-use change on ecosystem functions, and may help identify approaches that promote the recovery of degraded sites. We combined high-throughput sequencing of fungal rDNA and molecular barcoding of plant roots to estimate fungal and plant community composition in soil sampled across a chronosequence of deforestation. We found significant effects of land-use change on fungal community composition, which was more closely correlated to plant community composition than to changes in soil properties or geographic distance, providing evidence for strong links between above- and below-ground communities in tropical forests.
了解森林砍伐后微生物群落、植物群落和土壤性质之间的相互作用,可以深入了解土地利用变化对生态系统功能的长期影响,并可能有助于确定促进退化场地恢复的方法。我们结合了真菌 rDNA 的高通量测序和植物根系的分子标记,来估计在森林砍伐的时间序列中采集的土壤中的真菌和植物群落组成。我们发现土地利用变化对真菌群落组成有显著影响,其与植物群落组成的相关性比与土壤性质或地理距离的变化的相关性更强,这为热带森林地上和地下群落之间的紧密联系提供了证据。
