	Simpson testifies Nicole's problems drove him away (Site not responding. Last check: 2007-10-10)
		Jurors in Simpson's wrongful death trial will soon have to decide whether Simpson's anger and frustration at what he described as Nicole Brown Simpson's erratic behavior meant he was responsible for killing her and Ronald Goldman on June 12, 1994.
		As with the prosecutors in Simpson's criminal trial, the plaintiffs' strength in this civil trial is in the physical evidence, from DNA test results to the newly discovered batch of 30 photos purporting to show Simpson wearing the same rare model of Italian shoes as the one that left bloody imprints near the bodies.
		Simpson said it came to a head when his ex-wife yelled at him on the phone about the seating arrangements for a charity dinner, accusing him of meddling in her life by inviting one of her friends.

		The Shannon-Weiner Index explores the uncertainty that one individual organism in a habitat is of the same taxonomic category as another individual.
		This index increases as the probability of organisms being the same decreases, and therefore communities that are more biodiverse will have a relatively higher Shannon-Weiner Index.
		Simpson's Index provides a quantitative assessment of the probability that two individuals in the community are alike.

	A PRIMER OF SAMPLING DESIGN
		Simpson’s index is a composite measure of diversity.
		Simpson’s index varies from 1 to n (the number of species in the sample), with more diverse communities having higher values of D. Because n determines the maximum value of D, the magnitude of Simpson’s index is clearly influenced by the number of species in the community.
		As this example illustrates, Simpson’s index is more sensitive to changes in the abundant (rather than rare) species in a community.

		The [0,1] continuous index was discretized, and a byte representation [1,255] was stored at the center location (i.e., at the center pixel) in a new map.
		Each pixel in the new map is an index of land cover diversity, for the surrounding 65.61 ha window, for the corresponding pixel in the original land cover map.
		The index was then computed as one minus the sum of squares of land cover proportions within the quadrat.

	:: Diversity Indices :: (Site not responding. Last check: 2007-10-10)
		Since the Simpson index indicates the chance that two species are the same, it expresses lack of diversity.
		This index is the index that is most strongly influenced by evenness of the indices mentioned above (the Shannon index is most strongly biased towards richness).
		The philosophy behind the calculation of the index is similar to that of the Margalef and Menhinick indices: that larger abundance implies that species are less evenly distributed.

	Field Problems: Biological Diversity and Habitat Disturbance Indicators
		Using Simpson’s Index of Diversity, based on probability theory, one is able to measure the likelihood of two individuals drawn at random from a community will be the same species.
		However, biologists usually use the reciprocal of Simpson’s Index as a measure of “it feels like” so many species.
		Butterflies are used as an indicator of disturbance in that their diversity is inversely proportional to a forest’s integrity or lack of disturbance.

		The Index ranges from 0 to 1---the closer to 1 the less diverse the community.
		Thus, we see that census tract A has a lower index of diversity that tract B. If you calculate such an index over time it is important that you use a consistent number of groups.
		This index shows the extent to which each census tract departs from the overall proportion in the city.

	DIVERSITY INDICES
		Introduction: A diversity index is a mathematical measure of species diversity in a community.
		Methods: The Shannon diversity index (H) is another index that is commonly used to characterize species diversity in a community.
		Like Simpson's index, Shannon's index accounts for both abundance and evenness of the species present.

	DIVERSITY INDICES
		By taking relative abundances into account, a diversity index depends not only on species richness but also on the evenness, or equitability, with which individuals are distributed among the different species.
		Conclusions: Simpson's D is one of many diversity indices used by biologists.
		An ideal index would discriminate clearly and accurately between samples, not be greatly affected by differences in sample size, and be relatively simple to calculate.

		In the Simpson’s formula the pi represents the proportion that each species relative to the total number of individuals sampled.
		Lets run an actual calculation of D. Assume you collected 5 species in a sample of 60 individuals and that by some freak chance of nature there were 12 individuals of each species in the sample.
		To calculate the Simpson’s Index we would first determine the proportion (pi) of each species in the total sample (in this case it’s the same for all: 12/60 = 0.20) and square each one (to get 0.04).

		Both Simpson's index and Shannon's index are affected by the number of species and the evenness of species abundances, but they are affected differently.
		A rare species contributes much less to diversity in Simpson's index than in Shannon's.
		Thus, ``diversity profiles'' can be plotted to compare two or more communities over a range of evenness emphasis from no emphasis at all (species richness) to high emphasis (Simpson's index).
