Ecological species groups of South Carolina's Jocassee Gorges, southern Appalachian Mountains
across the landscape favorable for specific species groups. We also tested two multivariate methods for quantifying associations among species groups, and found that Mantel tests using traditional distance measures were inappropriate because of the double-zero problem of species absences, whereas canonical correlation modeled species group associations consistent with species distributions among sites. This study is among the first to develop ecological species groups in the southern United States, and the species group approach was useful for explaining vegetation-environment relationships, identifying groups of ground-flora and tree species that varied together across the landscape, and for determining the environmental gradients most strongly associated with species distributions.
期刊介绍:
The Journal of the Torrey Botanical Society (until 1997 the Bulletin of the Torrey Botanical Club), the oldest botanical journal in the Americas, has as its primary goal the dissemination of scientific knowledge about plants (including thallopyhtes and fungi). It publishes basic research in all areas of plant biology, except horticulture, with an emphasis on research done in, and about plants of, the Western Hemisphere.
