Increasingly conservative N cycling in a wet tropical forest: Litter and stream N concentrations decline over 29 years despite surges from hurricanes

open access: yesJournal of Ecology, EarlyView.
Conceptual model integrating short‐ and long‐term responses of N in litterfall and stream water in a wet tropical forest subject to hurricanes. Despite N surges following hurricanes, N cycling becomes more conservative in the absence of frequent hurricanes.
