Research Abstract

I conducted biochemical and ecological analyses on the topsoils collected underneath 5 replicates of each of 2 coniferous and 3 broad-leaved tree species. These species co-exist in a single forest and have different concentrations of foliar polyphenol. Soil microbial communities and the pattern of soil nitrogen mineralization differed among tree species. These spatial patterns corresponded with the patterns of dissolved polyphenols in soil water. I concluded that the foliar polyphenol was a proximate factor to form species-specific soil microbial communities and nitrogen mineralization rate.
