De verborgen talenten van mossen en korstmossen

The hidden talents of mosses and lichens

Tropical rainforests are the world's most significant source of biogenic volatile organic compounds (BVOCs). These compounds have a great influence on the concentration of oxidative substances and thus on the self-purifying power of the atmosphere. They also contribute to particle formation and influence the Earth's climate through cloud formation and precipitation. Until now, it was assumed that the leaves of the canopy forming trees were the most important source of these emissions. Now, however, scientists from the Max Planck Institute for Chemistry (Mainz), the University of Graz, and the Instituto Nacional de Pesquisas da Amazônia (INPA), among others, have discovered that also mosses and lichens emit large quantities of highly reactive and particle-forming sesquiterpenoids. These influence the atmospheric composition and affect air quality, climate, and ecosystem processes. Until now, mosses and lichens have been ignored in atmospheric and climate models.
