Picture of the Month


Prof. Dr. Christoph Scheidegger from the Swiss Federal Institute for Forest, Snow and Landscape Research, WSL, searching for lichens at Jungfrau East Ridge. Lichens are morphologically and physiologically adapted to extreme environments. Umbilicaria virginis (upper right individual) is one of the few species that exclusively grow in the nival environment at high altitudes. On the east ridge of Mt. Jungfrau the species is relatively frequent and can be recognized by the black fruitbodies on the upper surface (lower left) and the pinkish lower surface with simple rhizines (lower right). Pictures: Christoph Scheidegger and HFSJG.
