Moran’s I spatial correlograms of seed density for three downy birch populations of central Spain in 2005 and 2006. All correlograms were globally significant (P < 0.05). Solid symbols indicate significant coefficient values at P = 0.05. The circles indicate the “spatial range” of the seed–density patterns, i.e. where the I values cross the axis of I = 0. Different orientations are denoted by symbols. HO Honduras, NO Nogaledas, CM Casas del Monte
