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.

Dear Sanghoon,

I tend to think of heterogeneity referring to resource quality (or a
qualitative trait of the resource), whereas variability refers to resource
quantity.  Heterogeneity can differ both spatially and temporally.  

Sincerely,

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.
