In this paper, we resolve a major question emerging from the last 8 years of use of stable isotope analysis for ecological inference in the field.

Our current attempt to deal with this problem is to develop methods and instrumentation to allow real mapping, at geographical scales, of microbial organisms, with DNA-sequence specificity.

We applied simple methods typical of microbial ecology to a critical question of policy relevance. Now a lecturer in philosophy at the same university. My role in this paper was to conceive of the project, implement the necessary field capacity over the last 15 yearsand write.

The first explanation seems the most likely: It’s evident that the commercial interests of multinational companies are influencing what is supposed to be a scientific discussion.
