Contrasting impacts of nitrogen enrichment on soil nematode diversity in natural and managed ecosystems
收藏资源简介：
Soil nematode communities are increasingly subjected to pressures from multiple global change drivers, such as nitrogen (N) enrichment and land management practices. Although the critical role of N inputs in regulating soil nematode communities has been well studied, the contrasting responses of soil nematode diversity to N enrichment in natural versus managed ecosystems remain poorly understood. To address this knowledge gap, we conduct a global meta-analysis using 3323 paired observations from 173 publications to quantify the impacts of mineral N inputs on the richness and abundance of soil nematode diversity across natural ecosystems (e.g., unmanaged grasslands and forests) and managed ecosystems (e.g., croplands). N enrichment significantly reduced the richness and abundance of soil nematode communities in natural ecosystems, primarily driven by the prohibiting effects of N enrichment-induced soil ammonium toxicity and soil acidification on the abundances of plant-feeding, fungal-fe..., , # Data from: Contrasting impacts of nitrogen enrichment on soil nematode diversity in natural and managed ecosystems This README file was generated on 2025-04-27 by Xiaoming Lu.
