A Multi-Faceted Approach to Analyse the Effects of Environmental Variables on Geographic Range and Genetic Structure of a Perennial Psammophilous Geophyte: The Case of the Sea Daffodil Pancratium maritimum L. in the Mediterranean Basin
Fig 6
Statistics of the current, past and future potential distribution of Pancratium maritimum.
Bars in the panel (a) refer to the extent of the predicted distributions in each time interval, also depicting the fraction of suitable cells directly contiguous (grey bars) or not (black bars) to the sea. Panel (b) depicts the percentage of the coasts in the projection area, predicted as suitable (grey bars) or not (black bars), for the species in each time interval. Box plots in panel (c) report the latitude values of the predicted suitable cells in each time interval. The black, thick lines refer to the median, the boxes to the interquartile range and the whiskers to ± 1.58 multiplied by the interquartile range and divided by the square root of the number of values.
