SR23133Alpine meadow degradation decreases soil P availability by altering phoD-harbouring bacterial diversity
Understanding how the phosphorus (P) availability changes with meadow degradation is essential for the restoration of the alpine ecosystem. We investigated the phoD-harbouring bacterial community in four alpine meadows along a degradation gradient on the Tibetan Plateau and found alpine meadow degradation decreases soil P availability by regulating phoD-harbouring bacterial community diversity and alkaline phosphates, with soil water supply and plant biomass being the main driving factors. This study revealed the mechanisms of decreased P availability during alpine meadow degradation.
