Extended Data Fig. 6. Temporal changes in phylogenetic beta diversity of seagrasses under scenarios of climate change.

Extended Data Fig. 6

Estimates of phylogenetic beta diversity are based on the species distribution models of seagrasses (n = 66 species) fitted using maximum entropy and aggregated as the variation in phylogenetic composition between sites that is, between 100 km × 100 km grid cells. Indicated are the differences in phylogenetic beta diversity across 11 marine ecoregions for four different representative concentration pathways (RCP2.6, 4.5, 6.0, and 8.5) and for two time periods T1: 2040–2050 and T2: 2090–2100. Negative values indicate reductions in phylogenetic beta diversity (that is, phylogenetic composition will become more identical) and positive values correspond to increases in beta diversity (species composition will become more dissimilar) in the future.
