Unraveling the mechanisms underlying the maintenance of species diversity is a central pursuit in ecology. It has been hypothesized that ectomycorrhizal (EcM) in contrast to arbuscular mycorrhizal fungi can reduce tree species diversity in local communities, which remains to be tested at the global scale. To address this gap, we analyzed global forest inventory data and revealed that the relationship between tree species richness and EcM tree proportion varied along environmental gradients. Specifically, the relationship is more negative at low latitudes and in moist conditions but is unimodal at high latitudes and in arid conditions. The negative association of EcM tree proportion on species diversity at low latitudes and in humid conditions is likely due to more negative plant-soil microbial interactions in these regions. These findings extend our knowledge on the mechanisms shaping global patterns in plant species diversity from a belowground view.
揭示物种多样性维持背后的机制是生态学的核心追求。有假说认为，与丛枝菌根真菌相比，外生菌根（EcM）会降低当地群落中的树种多样性，这一假说仍有待在全球范围内进行验证。为填补这一空白，我们分析了全球森林清查数据，发现树种丰富度与EcM树比例之间的关系随环境梯度而变化。具体而言，在低纬度和湿润条件下，这种关系更为负相关，而在高纬度和干旱条件下则呈单峰型。在低纬度和湿润条件下，EcM树比例与物种多样性的负相关可能是由于这些地区植物与土壤微生物之间的相互作用更为负面。这些发现从地下视角扩展了我们对塑造全球植物物种多样性格局机制的认识。
