Extinction vs. New Species
“It is not the strongest of the species that survives, not the most intelligent that survives.
It is the one that is the most adaptable to change.” - Charles Darwin

MASS EXTINCTION & THE OCEANS TELL US ABOUT IT

To better predict the ecological and evolutionary effects of the emerging biodiversity crisis in the modern oceans, we compared the association between extinction threat and ecological traits in modern marine animals to associations observed during past extinction events using a database of 2497 marine vertebrate and mollusc genera. We find that extinction threat in the modern oceans is strongly associated with large body size, whereas past extinction events were either nonselective or preferentially removed smaller-bodied taxa. Pelagic (coastal and middle dwelling ocenic fish) animals were victimized more than benthic (bottom dwelling) animals during previous mass extinctions but are not preferentially threatened in the modern ocean. The differential importance of large-bodied animals to ecosystem function portends greater future ecological disruption than that caused by similar levels of taxonomic loss in past mass extinction events.
