On Definition and Quantification of Heterogeneity

This is the authors' abstract. We don't add key points for this paper.

General guidelines on the quantitative representation of heterogeneity in ecology are still lacking. Without a precise definition and sound quantification of heterogeneity, statements involving the concept will continue to be conclusing, and comparative studies and hypothesis testing will be ineffective. To solve this problem we propose an operational definition of ecological heterogeneity that facilitates quantification based on the data types of concern. We use two examples to demonstrate how our definition and quantification of spatial heterogeneity can he applied in practice
