Factors influencing the distribution of pteridophytes in a southeastern Ohio hardwood forest
Phytosociological and environmental analyses of the pteridophyte community of a mixed-mesophytic forest in southeastern Ohio were used to evaluate the influences of major environmental gradients on species distribution and community structure. The community was dominated by Adiantum pedatum, Aspleni...
