Table 3 The correlation coefficient (r) and significance (*P<0.05, **P<0.01, ***P<0.0001) for Mantel and Partial Mantel test calculated between genetic distances and geographic distances for all data, just Northern and central population and just Southern and central populations, with independent variable in the column and partialled-out variable in the rows

From: The influence of contemporary and historic landscape features on the genetic structure of the sand dune endemic, Cirsium pitcheri (Asteraceae)
