Figure 10.

Mathematica (upper panel) and R (lower panel) implementation test under extreme cases: (i) zero exposure and no background mortality (solid lines), (ii) high exposure over days 1–4 (100 [D]) (dashed lines) and (iii) zero exposure with a slight background mortality (dotted lines). The left panels show the scaled damage; the middle panels show the survival over time under the GUTS‐RED‐SD model; the right panels show the survival over time under the GUTS‐RED‐IT model. Parameter values for the GUTS‐RED‐SD model: k_D = 0.5 (time⁻¹), b_w = 0.3 (L mol⁻¹ time⁻¹) and z_i = 2.5 ([D]); parameter values for the GUTS‐RED‐IT model: k_D = 0.5 (time⁻¹), m_i = 2.5 ([D]) and β = 2 (−). Parameter h_b was equal to 0 for extreme cases (i) and (ii); h_b = 0.05 (time⁻¹) for extreme case (iii). Table 2 gives with the list of parameters and their explanation
