A University of Victoria micropaleontologist found that marine plankton may act as an early alert system before a mass extinction occurs.
With help from collaborators at the University of Bristol and Harvard, Andy Fraass’ newest paper in the Nature journal shows that after an analysis of fossil records showed that plankton community structures change before a mass extinction event.
“One of the major findings of the paper was how communities respond to climate events in the past depends on the previous climate,” Fraass said in a news release.
