Ecological persistence, incumbency and reorganization in the Karoo Basin during the Permian-Triassic transition

The geological persistence of biotic assemblages and their reorganization or destruction by mass extinctions are key features of long-term macroevolutionary and macroecological patterns in the fossil record. These events affected biotic history disproportionately and left permanent imprints on global biodiversity. Here we hypothesize that the geological persistence and incumbency of paleocommunities and taxa are maintained by patterns of biotic...
