Vegetation Productivity/Stability and Other Possible Ecological Invariant Relationships Demonstrated in a Microplot Multispecies Pasture Sward
Figure 2
Relationship between productivity (a), stability (b), and resilience (c) of pasture in respect of the number of species present and percentage contribution of first ranked species. Productivity plotted points coded for both productivity and frequency of observations. Productivity: triangle = 150+%, diamond = 120–150%, pyramid = 100–120%, circle = 80–100%, and square less than 80%. Frequency of observations in 5 classes: largest symbol for 100+ observations, then 50–100, 20–50, 10–20, and less than 10. (Note that species number axis is reversed in the stability and resilience graph for ease of presentation).
