Environmental indicators have been developed widely to promote biodiversity conservation, ecological restoration, and nature resource management from local to global scales. Ecoregions are effective tools for global conservation of plant diversity, and soil conditions can affect the plant diversity within ecoregions. Hence, soil indicators of plant diversity have substantial potential as tools for effectively understanding global ecoregions. Here, we used plant diversity data from 361 ecoregions and seven soil variables in a regression analysis to explore the relationships between soil and ecoregional plant diversity (EPD). We found that soil means and heterogeneity were significantly related to EPD. EPD decreased curvilinearly as both mean cation exchange capacity and mean soil pH increased, while mean soil organic carbon stock was negatively related to EPD (P |
