Species-lineage extinctions and speciation events during a turnover pulse; invasions and abandonments would also occur. The varied patterns include: A extinction of an abundant, ecologically dominant species; B extinction of a moderately abundant species; C rare species originating from an abundant ancestor; D an abundant species that undergoes a reduction in abundance, but subsequently recovers; E formerly abundant species reduced to rarity; F a rare species that persists through the turnover pulse; G a rare species that becomes abundant and ecologically dominant in the subsequent regime; H an abundant species derived from a rare ancestral species; I a rare species that vanishes early in the turnover pulse; and J a rare species yielding many descendant species (based on Miller 2005, Fig. 1)
