Abstract
ABSTRACT Patterns of tree species distributions in bottomlands are a result of various environmental and biological factors, including flood tolerance, seed dispersal, and species interactions. We evaluated the patterns of distribution and seed dispersal of tree species in a naturally regenerating bottomland hardwood forest in northeast Louisiana. We used nearest neighbor analysis to determine distribution patterns of the following canopy-dominant tree species: Carya aquatica, Celtis laevigata, Diospyros virginiana, Fraxinus pennsylvanica, Gleditsia triacanthos, and Quercus nigra. Results indicated an aggregated distribution pattern for Q. nigra, G. triacanthos, D. virginiana, and Ce. laevigata, while Ca. aquatica and F. pennsylvanica had random distributions in the study area. Additionally, we designed and used three types of seed traps to assess the seed dispersal of tree species. Modeled patterns of seed dispersal for F. pennsylvanica, Ca. aquatica, and Crataegus viridis indicated aggregated seed dispe...
