Observation Successional degree and rate of change varied among prairie treatments after plowing ceased.
Observation Species density, diversity and dominance changed among treatments over time.
Observation Community heterogeneity and dominance changed among treatments over time.
Observation Community heterogeneity decreased on four of five successional plots.
Observation Community heterogeneity increased in grazed prairie.
Observation Combining successional treatments produced more complex overall patterns.
Association Community heterogeneity fluctuated during succession with changes in species density.
Association Species diversity rose with species density.
Association Heterogeneity fell as species density rose.
