Fig. 4From: Phylogenomic analysis of Syngnathidae reveals novel relationships, origins of endemic diversity and variable diversification ratesGlobal diversity of Syngnathidae and Solenostomidae. Spatial distribution of phylogenetic diversity (i.e. the sum of all branches)Â and phylogenetic endemism (i.e. spatially restricted phylogenetic diversity)Â calculated on a geographic grid. Values are scaled to range between 0 and 1Back to article page
