Fungal biodiversity in dead leaves of fertilized plants of Dryas octopetala from a high arctic site
At a high arctic, polar semi-desert site (79°N) in Svalbard, nitrogen, phosphorus and potassium fertilizers were added to the soil for 5 yr to simulate increases in decomposition and nutrient mineralization which may occur as a result of increases in soil temperature and soil moisture caused by envi...
