Accounting for photodegradation dramatically improves prediction of carbon losses in dryland systems

Ecosphere, 2017
Traditional models of decomposition fail to capture litter mass loss patterns in dryland systems. This shortcoming has stimulated research into alternative drivers of decomposition, including photodegradation.
