What is it about?
Spatial genetics is a promising but young discipline, lacking efficient statistical tools to deal with a permanent issue: non-independence among spatial predictors. We showed how commonality analyses can help identify the true drivers of genetic differentiation, thus avoiding spurious conclusions stemming from collinearity issues.

Why is it important?
As a detailed variance partitioning procedure, commonality analyses allow disentangling the relative contribution of each predictor, identifying the amount of variance uniquely accounted for by each predictor and revealing suppression situations, where collinearity among predictors is responsible for spurious effects, that may otherwise have gone unnoticed.
