摘要：

Aster ledophyllus, a wind-dispersed herbaceous perennial of W Cascade subalpine zones, is slowly reinvading subalpine habitats devastated by the 1980 eruption of Mount St. Helens. Elk Cervus canadensis browsing significantly reduced both seed production and seedling recruitment, with larger plants being most affected by the elk. No significant effects, however, were detected for insect seed predators. -from Authors
