Other claims from this paper (12)
- Observation Protected, once-plowed and annually plowed prairie treatments had similar successional trajectories, while other plots diverged.
- 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 Mosaic diversity showed no clear pattern among treatments during succession.
- 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.
- Association Dominance fell as species density rose.
- Method / resource The authors concluded that no simple monotonic model adequately represents community structure during succession.
