How extinction of giant ice age beasts could still affect food chains
The extinction of large ice age mammals such as mammoths and saber-toothed cats around 10,000 years ago continues to influence modern food webs. A new study shows that the loss of these megafauna species triggered cascading ecological changes that persist today. Understanding these ancient disruptions may help predict the long-term effects of current biodiversity loss.
- ▪The extinction of megafauna like woolly mammoths and saber-toothed cats occurred within a 40,000-year span ending about 10,000 years ago.
- ▪Research published in PNAS analyzed predator-prey relationships across 389 sites in tropical and subtropical regions of the Americas, Africa, and Asia.
- ▪The study found that ancient extinctions significantly shaped today’s food web structures, particularly affecting species over one tonne.
- ▪Loss of top predators or large herbivores can trigger cascading effects throughout ecosystems, altering species interactions and landscape dynamics.
