science π Fungi underfoot boost forest plant variety
Fungal partnerships beneath the forest floor significantly shape the diversity of ground-level herbs. Researchers in China studied this in a temperate region, analyzing 34,850 trees and 389 herbaceous species in 2017. Forests with a mix of fungal partnerships showed richer understory communities compared to those dominated by one type. Climate patterns and nitrogen availability also play roles in determining herb diversity. Further studies are needed to fully understand how these mycorrhizal types affect species survival.
