Abstract
Summary
Phenolic compounds play a crucial role in northern peatland dynamics by inhibiting the degradation of organic matter in surficial peat layers. There is uncertainty as to how the phenolic content of both Sphagnum moss and northern peats will respond to intensified drought events, which are increasing in occurrence. This research aims to disentangle the fate of ‘free’ phenolics in peatlands by identifying and tracking a series of targeted, water-soluble phenolic acids, and determining their antioxidant capacity (following their release into peat DOM from peat/moss). The source, stability and fate of these compounds and the extent at which they contribute to the antioxidant pool in northern peats remains unknown.
