Abstract

Fecal pellets of small mammals (chipmunks, marmots and pikas), mountain goats and deer collected from the forefront of the rapidly receding Lyman Glacier in the North Cascade Mountains of Washington contained spores of both hypogeous and epigeous, ectomycorrhizal fungi. The forefront has been colonized by ectomycorrhizal hosts in the Pinaceae and Salix spp. Animal mycophagy thus provides inoculum for diversifying the populations of mycorrhizal fungi for early successional plants in the newly developing soils in this climatically stressful habitat.
