Ectomycorrhizal fungi and root water uptake respond independently to water availability

Oikos, Volume 2025, Issue 11, November 2025.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.
