Thank you very much for this reference. However the problem it is dealing with is not really similar to the one I target. In this paper the authors assess the differences in positions of neurones in a 2D plane between three groups of patients, with replicates in each group. So the data of interest are the coordinates. In my case, the positions of sampling stations are fixed (and on a grid if that helps [1]) and I want to assess the differences in abundances of two groups at these positions. So the data of interest are the abundances (normalized to remove the effect of total population sizes), and more specifically, the way the abundances are distributed on these points. Maybe the subject of this email is not correctly stated then. I am not a native english speaker and when it comes to technical terms, it is even worse. Anyhow, I hope this email clarifies things.
