More on meta-analyzing diversity

You may remember a post a few days ago summarizing something of a milestone paper by Bioversity scientists and partners which analyzed ten years’ worth of data on the diversity of 27 crops on farms in 8 countries around the world. As you’ll see if you revisit the original post, there’s been interesting discussion of the paper in the comments section. But I’ve been engaging the writers by email as well and it might be worth recounting the gist of that conversation.

The main point, I guess, is that they consider the crux of the paper as not so much the discussion of how/why diversity is being maintained on farm, as the fact that the richness/evenness relationship makes it possible to estimate one from the other (though separately for different kinds of crops). They see this as establishing really quite a novel framework for discussing — and generating hypotheses about — crop diversity.

It seems to me the discussion has started already.
