Selective press extinctions, but not random pulse extinctions, cause delayed ecological recovery in communities of digital organisms.

摘要: Abstract: A key issue concerning recovery from mass extinctions is how extinction and diversification mechanisms affect the process. We evolved communities of digital organisms, subjecting them to instantaneous “pulse” extinctions, choosing survivors at random, or prolonged “press” involving a period low resource availability. Functional activity trophic levels recovered faster than higher levels, with most extensive delays seen top level. Postpress generally did not fully recover functional in allotted time, which equaled that their original diversification. measured phenotypic diversity, observing considerable variation outcomes. Communities subjected pulse diversity substantially when press extinctions. Follow‐up experiments tested whether organisms shorter generation times contributed delay...
