Klebsormidium: Pendler zwischen scheintot und Wiedererwachen ist Alge des Jahres 2018

Sorry, in German only

Die mehrzellige Grünalge Klebsormidium lebt an Land an solchen Orten, wo keine andere Pflanze mehr wachsen kann. Als weltweit verbreiteter Pionier schafft sie neue Lebensräume, was Farmer und Wüstenanrainer nutzen. Forscher interessieren sich für ihre biologischen Tricks, wie sie zwischen leblos und Wiedererwachen hin und her wechselt. Die Professoren Andreas Holzinger (Universität Innsbruck) und Ulf Karsten (Universität Rostock) erforschen in enger Kooperation die Fähigkeiten, die die Alge vor Austrocknung und gefährlichen UV-Strahlen schützt. Beide sind Mitglieder der Sektion Phykologie der Deutschen Botanischen Gesellschaft (DBG), die Klebsormidium zur Alge des Jahres 2018 kürte.

Alga of the year 2017: Blue-Green Rock Dweller – ancient and still a pioneer

The algal researchers of the DBG nominated the Blue-Green Rock Dweller Chroococcidiopsis for the alga of the year 2017. The single celled organism lives inside rocks and lichens, survives extreme climatic conditions and makes hostile environments accessible – today and most likely thousands of millions of years ago as well. While doing so, it paved the way for plants and animals. The blue-green rock dweller, belonging to the cyanobacteria lives like all algae, from sunlight, and is of great interest to ecologists, biotechnologists, and desert- and space researchers. It is the favorite research subject of Prof. Dr. Burkhard Büdel from the University of Kaiserslautern, who has been investigating it for more than 30 years. He is a member of the Phycology Section of the German Society for Plant Sciences, DBG, in which the algal researches are organized and who nominate this year an alga of the year for the tenth time this year.

Sea Ice Alga Melosira arctica – winner or loser of climate change?

One of the most important microalgal species from the Arctic Ocean, Melosira arctica, has been nominated “Alga of the Year” by the German Phycology Section of the DBG. Scientists will use Melosira as a model to understand consequences of climate change. “Currently no one can foresee whether Melosira will benefit or suffer from the melting of sea ice, and nobody knows why it is so productive under such hostile conditions,” says biologist Klaus Valentin from the Alfred Wegener Institute (AWI). He is a Member of the Phycological Section within the Germany Botanical Society, which selected Melosira as Alga of the year 2016.
