Mycorrhizal fungi play key roles in the functioning of terrestrial ecosystems. The main types of mycorrhizal associations are arbuscular mycorrhizae, ectomycorrhizae, ericoid mycorrhizae and orchid mycorrhizae. Previous studies have shown that the abundance of plants with different types of mycorrhizal associations change gradually along latitudinal and altitudinal gradients driven by the effects of climate and soil nutrients. We aimed to understand how altitude and climatic and soil variables shape the distribution patterns of tropical plant mycorrhizal types and nitrogen-fixing plants along altitudinal gradients in the Andes.

热带安第斯山脉沿海拔梯度的菌根类型的多样性


菌根真菌在陆地生态系统的功能中起着关键作用。菌根关联的主要类型是丛枝菌根、外生菌根、外生菌根、外生菌根和兰花菌根。以前的研究表明，在气候和土壤养分的影响下，具有不同类型菌根关联的植物的丰度沿纬度和海拔梯度逐渐变化。我们旨在了解海拔、气候和土壤变量如何塑造安第斯山脉沿海拔梯度的热带植物菌根类型和固氮植物的分布模式。
