Effects Of Willows (Salix Brachycarpa) On Populations Of Salicylate-Mineralizing Microorganisms In Alpine Soils, Steven K. Schmidt, David A. Lipson, Ted K. Raab
Ted K. Raab
We used the substrate-induced growth-response (SIGR) method to quantify salicylate-mineralizing microbes and total microbial biomass in soils from under willows (Salix brachycarpa) and in surrounding meadows dominated by the sedge Kobresia myosuroides. Willows had a strong effect on the biomass of salicylate-mineralizing microbes in both years of this study. There were always higher biomass levels of salicylate mineralizers in soils from under Salix (4.6–10.1 ug C/ g) than under Kobresia (0.23–0.76 ug/ g). In contrast, total microbial biomass was not significantly different under these plant species in 1996 and was only higher under Salix on one date in 1997. These …
