Figure 2. — Scatter plots and linear regressions of the observed relationship between (A) the search time for nitrate and ammonium (F_1,26 = 100.4, P < 0.0001, R² = 0.79), (B) the handling time for nitrate and ammonium (F_1,26 = 31.2, P < 0.0001, R² = 0.53), (C) V_max for nitrate and ammonium (F_1,26 = 31.2, P < 0.0001, R² = 0.53) and (D) K_m for nitrate and ammonium (F_1,26 = 43.2, P < 0.0001, R² = 0.61). Fresh (fw) and dry (dw) weights are plotted separately, but the patterns were qualitatively similar and so they were pooled for regression fits. Data were ln(x + 1) transformed.
