Location: Mather Hall Rittenberg Lounge Craig Schneider, Charles A. Dana Professor of Biology  Since the time of Linnaeus, taxonomists have used morphological characteristics to distinguish traits that link and separate biological species. Craig Schneider’s study of the seaweed flora of Bermuda began long before the use of gene sequencing as a taxonomic tool. His lecture will explore how molecular-assisted alpha-taxonomy has changed from earlier taxonomic knowledge in this isolated Atlantic archipelago.  A light lunch will be provided on a first-come, first-served basis.
