Professor Beatty will make a series of measurements of upland           deciduous forest floor species composition resulting from seed fall,            overland movement of seeds, and other dispersion mechanisms.  The               measurements will be made in a variety of forest environments including         old fields, floodplain forests, successional forests, and conifer forests.      Local relief will also be considered.                                                   The project is designed to determine whether seed dispersal is the      controlling factor in species colonization or whether environmental             conditions are more important.  The project will yield a deeper                 understanding of the determinants of vegetational change and succession,        and contribute thereby to basic and applied biogeography.  The findings         will also contribute to our understanding of successional processes of a        spatial nature among other phenomena at larger scales of analysis.
