Altitudinal gradients of bryophyte diversity and community assemblage in southern Appalachian spruce-fir forests
This article is part of a larger document. View the larger document here.Abstract
Ground-layer plant communities in spruce-fir forests of the southern Appalachians have likely undergone significant change since the widespread death of canopy Fraser fir (Abies fraseri) caused by the exotic balsam woolly adelgid (Adelges piceae). Bryophytes comprise an important part of the ground-layer flora in the spruce-fir zone, with an average cover of 26 percent and richness and diversity values rivaling those of the herbaceous layer, yet few contemporary studies have given them significant attention.
