Extended Data Fig. 7: Projected compositional shifts in bacterial diazotrophs in areas of dominant community change.

(a) 180–2000 μm (b) 20–180 μm (c) 5–20 μm and (d) 0.22–3 μm. Top: Locations of dominant province change using colours corresponding to the type of province transition. Bottom: Circular plots summarizing significant compositional shifts in marine diazotrophs. Each type of transition is represented by an arrow coloured according to the map and in grey if they represent less than 2% of the transitions. Barplots represent mean relative abundances of each group of organism. Arrows points towards the end of the century projected province and their widths are proportional to the area of change. Significant compositional changes in a type of organism are represented by triangles of the associated transition. We generated these map using R-package maps⁵¹.
