Assessment of percent ectomycorrhizal colonization of plant roots from randomly selected cores taken in Long-term ecological research (LTER) soil warming and fertilization plots.

In the summer of 2007, we collected soils from treatment plots that are maintained as part of the Arctic Long-term Ecological Research (LTER) site at Toolik Lake, AK (68o38'N, 149o34'W, elevation 760m), since 1989. Treatments include warming by greenhouses and fertilization (10 g m-2 year-...

Description
Summary:In the summer of 2007, we collected soils from treatment plots that are maintained as part of the Arctic Long-term Ecological Research (LTER) site at Toolik Lake, AK (68o38'N, 149o34'W, elevation 760m), since 1989. Treatments include warming by greenhouses and fertilization (10 g m-2 year-1 N as NH4NO3; and 5 g m-2 year-1 P as Ca P) in a factorial design. Three replicate soil cores were taken from each tratment plot. Plant roots were obtained from soil cores by washing. Roots were assessed for ectomycorrhizal status using microscopy. : Purpose: Assessment of long-term warming and fertilization on the diversity and biomass of ectomycorrhizal fungi. : Summary: Not Applicable
