There are some 10-12,000 known species of freshwater diatoms, with a further 200-250,000 suspected species.
A series of Botany Department projects is investigating their morphology, phylogenetic relationships and distribution relative to all organisms surrounding the margins of the Pacific Ocean.
The Botany Department’s algal-related research programme includes projects to map and record seaweed biodiversity in the North Atlantic and detailed studies of red algae.
Our diatom research covers both extinct and existing taxa. Among the projects are a number that focus on diatom biodiversity while others address formation of the unique cell wall.
