Angiosperm-gymnosperm differences in wood decomposition modulate nutrient deposition effects on soil fungal communities and multi-nutrient cycling in a subtropical forest

This study was conducted at the Tiantong National Forest Ecosystem Research Station, Ningbo, Zhejiang Province, China (29°48′N, 121°47′E). We established a three-year wood decomposition experiment using three angiosperm and three gymnosperm species, with nitrogen and phosphorus additions simulating regional atmospheric deposition, to test the interactive effects of nutrient inputs and tree taxonomic groups on soil fungal communities and their functions. We show that tree taxonomic identity and nutrient inputs jointly regulate fungal functional groups diversity and interactions, thereby accelerating soil carbon and nutrient cycling.
