Based on the most excellent dendrogram work of Mike Bostock leveraging d3, this shows the nested scales by which the ~10,000 global ecoregions combine in clusters that have similar drivers of species richness (land use intensity, climate, etc.). Data is from forthcoming work by Bill Morris on geographically-weighted regression and ecological segmentation; it would be “done” rather than “forthcoming” if Bill would spend less time on dataviz and more on writing his %$&#ing dissertation.
