Other claims from this paper (11)
- Observation Vegetation composition showed no consistent directional change from 1906 to 1978.
- Observation Absolute cover and density fluctuated greatly for most species.
- Observation Dominant species had generally similar relative cover within each plot over time.
- Association Species cover responded strongly to extremely wet or dry years.
- Observation Total cover increased in many plots between 1906 and 1978.
- Observation Density increased in many plots between 1906 and 1978.
- Observation Species diversity increased in many plots between 1906 and 1978.
- Observation Species formed five groups based on population dynamic traits.
- Observation One end of the species continuum had long lifespans, high survivorship, large mature size, low density, erratic recruitment and older age structure.
- Observation The other end of the continuum had short lifespans, low survivorship, small mature size, high density, frequent recruitment and young age structure.
- Association High early survivorship and erratic recruitment were not necessarily related.
