Rhus radicans, a root-climbing liana, is not distributed randomly among potential host tree species in an old-growth mixed mesophytic forest on the southern Cum- berland Plateau of north Alabama, USA. Vines are more abundant than expected on Carya ovata and Quercus rubra, but less abundant than expected on Juglans nigra, Acer sac- charum, and Sassafras albidum. Seed germination and early seedling growth in the presence of bark extracts suggest allelochemical interactions may influence the observed host pref- erences. |
