Abstracts |
The effect of experimental warming on the root-associated fungal community of
arctic willow (Salix arctica) was studied in three distinct habitats at a tundra site in the
Canadian High Arctic. Plots were passively warmed for 5-7 years using open-top chambers and
compared to control plots at ambient temperature. Fungal communities were assessed using terminal
restriction fragment length polymorphisms. We found the following: (1) the root-associated fungal
community in these high arctic tundra habitats is highly diverse; (2) site and soil
characteristics are the most important drivers of community structure and (3) warming increased
the density of different genotypes on individual root sections but has not (yet) affected the
composition, richness or evenness of the community. The change in genotype density in the warmed
plots was associated with an increase in PCR amplification efficiency, suggesting that increased
C allocation belowground is increasing the overall biomass of the fungal community.
