Dec 7, 2018 · Simulated Permian habitat is available for ~95% of modern Metabolic Index trait combinations, both as global ocean volume (points in Fig. 3A) and as area on the seafloor (fig. S7A), further confirming that extant trait diversity is well adapted to the end-Permian ocean and is thus a sensible baseline for examining habitat loss and extinction. The end-Permian mass extinction not only decimated taxonomic diversity but also disrupted the functioning of global ecosystems and the stability of biogeochemical cycles.
