Photodegradation of plant litter cuticles enhances microbial decomposition by increasing uptake of non-rainfall moisture

J. Robert Logan, Paul Barnes & Sarah Evans
Litter decomposition plays a central role in carbon cycling in terrestrial ecosystems worldwide. In drylands, which cover 40% of the Earth’s land surface, photodegradation and biotic decomposition driven by non-rainfall moisture are important mechanisms of litter decay, though studies have only recently begun examining interactions between these two processes. We describe a novel priming mechanism in which photodegradation and biotic decay of the cuticle of plant litter increases litter absorption of non-rainfall moisture (fog, dew,...
