Greater variations of rhizosphere effects within mycorrhizal group than between mycorrhizal group in a temperate forest

The presence of living roots can markedly change soil properties, microbial activities, and biogeochemical cycling in the rhizosphere compared to bulk soil. Such rhizosphere effect has been increasingly recognized to play a crucial role in carbon (C) and nitrogen (N) cycling in terrestrial ecosystems. Here, we investigated the rhizosphere effects of 12 tree species associated with two contrasting mycorrhizal types (arbuscular mycorrhizal, AM vs....
