Figure 5

Relative contribution of urea and glucose to total cryoprotectant load in several organs of winter and spring wood frogs sampled after experimental freezing. Derived from values for group means as depicted in Figures 2 and 3. Data from winter frogs were initially reported in Costanzo et al. [10].
