Michelle Casanova

Phycologist (Charophytes)

Michelle has been working on the ecology and taxonomy of water plants since 1988. Her major interest is in the family Characeae, the charophytes. Charophytes are macroalgae of inland waters, and the closest living relatives of the ancestors of land plants. They are indicators of water quality and water regime, and are the basis of many aquatic food webs. Australia has a huge diversity of charophytes, and there are many new and endemic species.
