Mycorrhiza formation and diversity in undisturbed forest and clearcut and burned areas in three forest types in Oregon

Abstract:

A greenhouse bioassay was used to compare ectomycorrhiza formation and diversity in soils from undisturbed and clearcut and burned areas in moist mesic, moist montane and dry montane forest types representing a gradient of environmental harshness. It was hypothesized that mycorrhiza diversity decreases with increasing environmental harshness and that stability...
