Localization of sampling sites and visualization of the number of surveyed plots along the dune vegetation zonation. The size of the circles is proportional to the total number of plots, and the slices represent the number of surveys in each zone along the dune gradient. Site numbers refer to sampling locations ordered from north to south, and colors indicate different vegetation zones. 1. Biotope of Martinsicuro; 2.
