Alge des Jahres
Die Alge des Jahres wird seit 2007 von der Sektion Phykologie in der Deutschen Botanischen Gesellschaft ernannt[1]. Gekürt werden Arten beziehungsweise Gattungen, die in ihrer ökologischen Bedeutung oder ihrer Bedrohung hervorhebenswert sind.

Small laminaria hyperborea
Green algal cell (Chlamydomonas nivalis) responsible for red coloration of mountain snow packs. This organism utilizes pollutants carried in snow as a food source and reduces the acidity of meltwater. Thin section observed using TEM. Magnified 10,000X.

An international team of scientists has found that a strange type of bacteria can turn light into fuel in incredibly dim environments.
Similar bacteria could someday help humans colonize Mars and expand our search for life on other planets, researchers said in a statement released with the new work.
Organisms called cyanobacteria absorb sunlight to create energy, releasing oxygen in the process. But until now, researchers thought these bacteria could absorb only specific, higher-energy wavelengths of light. The new work reveals that at least one species of cyanobacteria, called Chroococcidiopsis thermalis — which lives in some of the world's most extreme environments — can absorb redder (less energetic) wavelengths of light, thus allowing it to thrive in dark conditions, such as deep underwater in hot springs. [Extreme Life on Earth: 8 Bizarre Creatures]
"This work redefines the minimum energy needed in light to drive photosynthesis," Jennifer Morton, a researcher at Australian National University (ANU) and a co-author of the new work, said in the statement. "This type of photosynthesis may well be happening in your garden, under a rock." (In fact, a related species has even been found living inside rocks in the desert.)
When grown in far-red light, this cyanobacteria, called Chroococcidiopsis thermalis, can still photosynthesize where others falter.
