How to Calculate and Interpret Pielous Evenness Index Pielou’s Evenness Index (also known as the Shannon Equitability Index) helps ecologists measure and understand these distribution patterns, revealing how equitably species share their habitat Species evenness describes how close in numbers different species are within an ecosystem
Does Evenness Even Exist? - PMC Ecologists say that distributions are “even” when species have similar abundances and “uneven” when one or a few species dominate In other words, “evenness” is the standard ecological term for variability This concept is central to the field's history and current practice
