Recently, a former member of the Lindroth Research Group published a manuscript on condensed tannins and nitrogen recovery in New Phytologist. Madritch and Lindroth investigated how condensed tannin concentration in aspen leaves and below ground nitrogen cycling are influenced by herbivory. High levels of condensed tannins were correlated with nitrogen recovery within the same and following seasons in defoliated trees suggesting that tannins may be mediators of tolerance rather than resistance.
