Mosses and lichen appear to play a previously overlooked but important role in the atmospheric chemistry of tropical rainforests. A new study from Achim Edtbauer and colleagues shows that such cryptogams emit highly reactive and particle-forming compounds (BVOCs) that are important for air quality, climate, and ecosystem processes.
A new study by Löbs et al. in Biogeosciences documents the microclimatic conditions for tropical mosses as a baseline for studies on their overall relevance on biogeochemical cycling. They found that water and light are overall the most important requirements for them to become photosynthetically active. However, their habitat determines which of the two plays the bigger role.
Fungal spore emissions are an important contributor to biogenic aerosols, but we have yet to understand under what conditions fungi release their spores. Nina Löbs and co-authors developed a new technique to measure emissions from single organisms and tested this out at ATTO and with controlled lab experiments. They published their results in the Open Access Journal Atmospheric Measurement Techniques.
