Pianka's index of niche overlap is defined in his papers from 1973 and 1974, as: where O k l is the resource overlap between species k and l, and since the index is symmetric O k j = O l k. p i b represents the proportion of resource i that is used by species b. The index is a modification of one presented in MacArthur & Levins (1967).
