Cryptogams are an important source for BVOC emissions in tropical forests

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.

Water and light drive photosynthetic activity of Amazonian mosses

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.
