A gradual #decline in #biodiversity may have led to a more devastating #ecosystem #collapse during the #PermianTriassic #MassExtinction , according to #NewResearch .
#Scientists #recreated #ancient #FoodWebs to determine how #species were #impacted during this event. But how well can our knowledge of past #extinction events #inform us about the #CurrentCrisis of #SpeciesLoss ?
