Vertical lines representtransitions between active and hibernating seasons. (A) OCN concentrations arerepresented by a line for each bear. (B) Single smoothed curve represents the averageof all 9 bears. Arrows indicate the dates at which “peak-valley” means were analyzed.(C) Each total OCN concentration was normalized to the average total OCNconcentration for the appropriate bear for better comparison of seasonal fold changes.43
