Spatial population structure revealed through spatial principal components analyses. Spatial Principal Components Analyses of the Madagascan EACMV-like DNA-A core CP (a), EACMV-like DNA-B (b) and ACMV DNA-B (c) sequences. The locations of samples are represented with squares coloured according to a black to white gradient corresponding to the eigenvalues for the first axis of the sPCA. The p-values of the global spatial structure detected in each dataset are presented
