Phospholipid fatty acid (PLFA) profiles and 13C-enrichment values for 23 PLFAs from rhizosphere, organic and mineral soils surrounding Betula nana, Ledum palustre, and Salix pulchra plants, 4 sampling dates.

We tested the influence of three different tundra plant species (Salix pulchra, Betula nana, and Ledum palustre) on the soil microbial community composition in bulk organic, mineral and rhizosphere soils. We used stable isotope techniques to study carbon transfer from plants labeled with 13CO2 in situ to the soil microbial community, and PLFA analysis to test the resulting effect on the microbial community composition.
