Information Theory and Biological Diversity (UMAP)

Author: Steven Kolmes and Kevin Mitchell


This module discusses and derives the key properties of one measure of diversity, the entropy function, and illustrates its use by ecologists and animal behaviorists. By the end of this module students will: 1) be familiar with one common measure of diversity; 2) know how to apply this measure to ecological problems, and 3) have a greater appreciation for the Mean Value Theorem.
