Arrhenius and Gleason species-area models differ in their sensitivity to environmental, community, and individual plant characteristics. The spatial scale that is the most suitable for revealing the factors underlying species diversity is the smallest considered (0.01 m2). The most important factors were spatial pattern in community structure (evenness, lateral spread), plant mobility (lateral spread and persistence), and soil properties. Although Gleason model showed better fit to data (both non-log and log transformation) and its intercept was more sensitive to tested biological characteristics.
