Coccolithophores: Microscopic Architects Reveal the Secrets Of Marine Evolution Under Ancient and Modern Climate Change
Our oceans are full of microscopic plants called phytoplankton. One such group, the coccolithophores, have cells smaller than the width of a human hair, yet they produce exquisite exoskeletal calcite plates that are readily preserved in marine sediments over time, recording the progressive success and demise of individual cells and entire species since their first appearance 220 million years ago. This talk will showcase some of the exciting new avenues of paleontological research that are establishing direct links between ancient coccolithophore remains and the ecophysiological response of modern coccolithophore populations to environmental change in order to advance our understanding of plankton evolution under different climate states.
