Micrasterias - immortal but in the Red Data Book for endangered species

Micrasterias furcata has a diameter of only 0.2 millimeters and occurs in boggy areas. It is classified as ‘endangered’ according to the Red Data Book of 2008. Since it was first discovered and described by scientists it has been observed only in three locations in Germany. The species is classified as ‘near threatened’ in Austria.

Algenforscher der Sektion Phykologie der Deutschen Botanischen Gesellschaft wählen die Zieralge Micrasterias zur Alge des Jahres 2008. Micrasterias, aus dem Griechischen abgeleitet etwa „kleines Sternchen“, ist eine stark bedrohte, formen- und artenreiche Algengattung, die auf intakte Gewässer angewiesen ist.

More Micrasterias images

Micrasterias ceratofera is a spiky exotic species from south-east Asia, first described in 1985. The species lives on the bottom of tropical water bodies such as lakes and rivers, and sometimes free-floating as plankton. In contrast to most of the Micrasterias species that occur in Germany, Micrasterias ceratofera does not inhabit boggy places and its distribution in the tropics does not appear to be threatened. The alga on this image was originally collected from Indonesia in 1983. It was brought back to Germany and has been growing in culture ever since. This culture is available for scientific research in the "Sammlung von Conjugaten-Kulturen (SVCK; Culture Collection for Conjugate Algae)’ at the Institut für Allgemeine Botanik at the University of Hamburg.

Further Information

Members of the Phycology Section (Algology) (www.dbg-phykologie.de/en.html) conduct research on algae and investigate, amongst others, taxonomical, ecological, physiological and molecular topics on macro- and microalgae. The Section promotes algal research and supports young scientists. The Section is one of five subject-specific Sections of the German Society for Plant Sciences (Deutsche Botanische Gesellschaft, DBG, www.deutsche-botanische-gesellschaft.de/en.html).
