Does nitrogen deposition affect soil microfungal diversity and soil N and P dynamics in a high Arctic ecosystem?
In a high Arctic polar semidesert ecosystem (ambient N deposition c. 0.1 g N m-2 a-1), the effects of N enrichment on the diversity of soil microfungi and on N content and availability in organic and mineral soils were determined. Three N (total: 0, 0.5, 5gN m-2 a-1) and two P (total 0, 1 g m-2 a-1)...
