[20-1] - KEYNOTE - Learning from the present to inform the past and future of coccolithophore calcification
Abstract: Coccolithophores are an important group of marine phytoplankton. Their unique feature is the ability to form a calcareous shell - the coccosphere - composed of several individual plates (coccoliths) attached to the cell surface. Coccolithophores are sensitive to environmental change, which...

| Summary: | Abstract: Coccolithophores are an important group of marine phytoplankton. Their unique feature is the ability to form a calcareous shell - the coccosphere - composed of several individual plates (coccoliths) attached to the cell surface. Coccolithophores are sensitive to environmental change, which is reflected in their variable species diversity, cell abundance, and coccolith morphology observed in the paleorecord since the Triassic. In this seminar I will present results from laboratory and field studies where coccolithophores were exposed to environmental stress (mainly ocean acidification). I will utilize the outcomes of these studies to derive predictive understanding, which may help us (i) to understand observed changes of coccolithophore abundance in the past, and (ii) better project their future in a rapidly changing climate. In this context, I will link our understanding of coccolithophore responses to perturbation with ecological theory. I hope to provide compelling arguments why ecological concepts should be considered when interpreting past ,and predicting future, abundance of coccolithophores. Authors:* Bach L.* |
