Digital Image Collection of Desmids
Desmids are microscopic single-celled green algae with a typical symmetrical appearance. The cells are divided in two halves ('semicells') that are mirror images of each other and they show a remarkable variation in shape and ornamentation. Because desmids thrive in clear and nutrient poor freshwater, they gain increasing attention from ecologists for assessing and monitoring wetland areas.
