Species-rich, poorly-understood taxa
Scanning electron microscope image showing a living species of pennate diatom found in shallow seas. Similar species are common in fresh water.
Interdisciplinary research into species-rich, poorly-understood taxa
This project focuses on the ‘araphid’ diatoms - numbering around 4-5,000 known species, with many more still to be described.
Although a non-monophyletic group, it is significant because it contains species that relate to the largest two clades.
