Microbial community composition but not diversity changes along succession in arctic sand dunes
Summary The generality of increasing diversity of fungi and bacteria across arctic sand dune succession was tested. Microbial communities were examined by high‐throughput sequencing of 16S rRNA genes (bacteria) and internal transcribed spacer (ITS) regions (fungi). We studied four microbial compartm...

Summary The generality of increasing diversity of fungi and bacteria across arctic sand dune succession was tested.
