Briefly explain the measures and indices of diversity.
Answers
Simpson's Index (D) measures the probability that two individuals randomly selected from a sample will belong to the same species (or some category other than species). This figure would represent a community containing only one species. The higher the value, the greater the diversity.
In the classical definition, which is standard throughout the physical sciences, measurement is the determination or estimation of ratios of quantities. Quantity and measurement are mutually defined: quantitative attributes are those possible to measure, at least in principle.
Diversity Indices:
A) A diversity index is a mathematical measure of species diversity in a given
community.
B) Based on the species richness (the number of species present) and species
abundance (the number of individuals per species).
C) The more species you have, the more diverse the area, right?
D) However, there are two types of indices, dominance indices and information
statistic indices.
