Unformatted text preview: Shannon’s H : Has similar properties to Simpson’s D , but the range of values differs. An example of a study that uses Shannon’s H is one by Foster et al. (2002, Oikos). This study looked at starting diversity in Kansas grassland communities and how that correlated with standing crop, light penetration and disturbance, as shown in the figure below. Note that the range of values of H is different than the range in values in D that was observed in the Johnson & Agrawal study. This is typical of these indices.
