A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...
