Extended Data Fig. 4: Numbers and proportion of endemic vascular plants on islands in relation to island area, isolation and absolute latitude across all islands in each category.
From: Islands are key for protecting the world’s plant endemism
Islands are grouped into continental (560 islands), complex origin and fragment (31) and oceanic (1,060). Only significant relationships are shown. Latitude is shown in absolute degrees. Species-area relationship z-values (A, D) are as follows: (A) continental islands: z = 0.47; complex origin and fragment islands: z = 0.72; oceanic islands: z = 0.28. (D) continental islands: z = 0.02; complex origin and fragment islands: z = 0.05; oceanic islands: z = 0.01.
