| Abstract | Intersite variation in ectomycorrhizal (ECM) inoculum potential in soils from 16 sites located in arid subal pine areas of the White Mountains of California was quantified. The study sites included valleys dominated by big sagebrush ( Artemisia tridentataNutt.) and mountainsides dominated by ancient Great Basin bristlecone pine ( Pinus longaevaBailey). ECM inoculum potential was not detected at three of four valley sites nor in 42% of forest soil sam ples. Only 10 mycorrhizal species were detected in bioassays, and four of those accounted for 94.5% of all colonized seedlings, in order of decreasing abundance these were Pyronemataceae sp., Rhizopogonsp., Wilcoxina rehmiiYang & Korf, and Cenococcumsp. These species were identified also from in situ mycorrhizal roots. The abundance of the dominant Pyronemataceae sp. was significantly positively correlated with pH, which at all forest sites was high com pared with typical conifer forest soils. Our results show that the ECM inoculum potential of soils is low, homogeneous, and spatially restricted in these ancient high-elevation forests. |
