Meta-analysis reveals differing plant–soil feedbacks in ectomycorrhizal and arbuscular mycorrhizal woody plants, suggesting implications for community assembly.
Key Points
This research aims to analyze global plant–soil feedbacks (PSFs) linked to mycorrhizal types in woody plants.
Conducted a meta-analysis of existing data from 1994 to 2022
Investigated PSFs for ectomycorrhizal and arbuscular mycorrhizal woody plant hosts
Compared PSFs across various regions including North America, Asia, Europe, and Oceania
Ectomycorrhizal hosts experienced generally positive PSFs compared to negative PSFs for arbuscular mycorrhizal hosts
Effect size differences were strongest in North America and Asia, but not significant in Europe and Oceania
Negative PSFs for arbuscular species were noted in wet and cool regions, while ectomycorrhizal species showed no latitudinal or climatic gradient effects
