Fiona's home state of South Australia boasts a unique marine environment, lying on the longest stretch of south-facing coast in the southern hemisphere. This geographical feature, coupled with a wide range of latitudes and land formations, gives rise to many different physical environments. Seasonal upwellings of cold, nutrient-rich water, most notably the Bonney upwelling in the state's South-East, contribute to the highest levels of species richness and endemism of marine algae in the world.
However, Fiona is well aware that this rich biodiversity is at risk. "With climate change looming, along with a raft of other human-induced threats to the marine environment, I fear we will lose much of this biodiversity before we've even begun to understand it," Fiona warns. Her concern is not unfounded. A great deal of work was undertaken in the field of Phycology (the study of seaweed) in Southern Australia in the 20th century, but this area of research appears to have been left behind somewhat in the 21st century.
