Title: Mycorrhizal Associations of Selected Plant Species from San Miguel Island, Channel Islands National Park, California 
Author: Koske, Richard E.; Halvorson, William L.

Citation: Koske RE, Halvorson WL. 1989. Mycorrhizal associations of selected plant species from San Miguel Island, Channel Islands National Park, California. Pac Sci 43(1): 32-40.
Abstract: Vesicular-arbuscular mycorrhizae (VAM) were detected in six
native plant species: Camissonia cheiranthifolia ssp. cheiranthifolia, Coreopsis
gigantea, Distichlis spicata, Dudleya greenei, Eriogonum grande ssp. rubescens,
and Lavatera assurgentiflora. Levels of root colonization were greater in
November than in July. No mycorrhizae were apparent in plants of Cakile
maritima, Mesembryanthemum crystallinum , or M. nodiflorum. A total of ten
species of VAM fungi , three of them undescribed, were recovered from root
zones of Dudleya, Coreopsis, and Lavatera. Genera of fungi included
Entrophospora, Glomus, and Scutellospora. The reinvasion of barren areas of the
island from which some native plant species were extirpated by overgrazing and
erosion may be dependent upon the reestablishment of a population of VAM
