MIAMI, Feb. 26, 2021 /PRNewswire/ A world without sharks is a world less resilient to extreme climate events, scientists say.
Predators, including some sharks, are known to be critical for maintaining stability and biodiversity in the world s oceans. But according to a new study, they are also critical in helping ecosystems recover when devastation hits from hurricanes or marine heatwaves.
In a unique study, a team of scientists tested whether an ecosystem could recover if sharks were no longer there to keep other animals in check. The answer is no, according to Mike Heithaus, a co-author of the study, marine ecologist and dean of Florida International University s College of Arts, Sciences & Education.
