You might want to have a look at a book "Ecological Heterogeneity" edited by J. Kolasa and S.T.A. Pickett (1981; Springer). The book contains a conceptual review and a variaty of applications and implementations of these two concepts.

Heterogeneity can differ both spatially and temporally. Sincerely, Pablo Munguia Date: Fri, 28 May 2010 18:17:46 -0400 From: =?iso-8859-1?Q?Sanghoon_Kang?= <[email protected]> Subject: heterogeneity vs. variability I was writing a paper discussing spatial heterogeneity of soil measurements. At the moment, I became confused between the concept of heterogeneity and variability. To me 'heterogeneity' contains 'spatial' context, and 'variability' has 'variations of values'. Thus 'heterogeneity of N' means 'N concentrations are different at different sampling locations', while 'variability of N' means simply 'variations of N concentration without considering locations of sample'. Then in the context of 'spatial' it seem like they become indistinguishable. But I feel like they are not exactly same. Any insight? SANGHOON KANG.
