Fig. G1. Residuals from the nonlinear regression best fit type III functional responses fitted to in ingestion rate (mg C per mg C of *Daphnia* per d; panels A–D) and clearance rate (L per mg C of *Daphnia* per d; panels E–H) as shown in Fig.2. Species pairs are: *D*.* hyalina *and *M*.* minutum *at 20°C (A and E) and 14°C (B and F), *D*.* hyalina *and *C*.* meneghiniana *at 16°C (C and G), *D*.* magna *and *M*.* minutum *at 16°C (D and H).

Fig. G2. Residuals from the nonlinear regression best fit type III functional responses fitted to ingestion rate (mg C per mg C of *Daphnia* per d; panels A–D) and clearance rate (L per mg C of *Daphnia* per d; panels E–H) as shown in Fig. 2 plotted against predicted values. Species pairs are: *D*.* hyalina *and *M*.* minutum *at 20°C (A and E) and 14°C (B and F), *D*.* hyalina *and *C*.* meneghiniana *at 16°C (C and G), *D*.* magna *and *M*.* minutum *at 16°C (D and H). Significant heteroscedasticity detected with the Breusch-Pagan test is marked by * (*p* <0.05), ** (*p* <0.01) or *** (*p* <0.001).

Fig. G3. Type III functional response curves plotted as ingestion rates (mg C per mg C of predator per d; panels A–C) and clearance rates (L per mg C of *Daphnia* per d; panels D–F). The default parameter values are: *a*=10, *b*=1.8 and *h*=0.5 (red lines). Blue and green lines illustrate the sensitivity of ingestion and clearance rates with respect to changes in the attack rate coefficient (*a*; A and D), functional response exponent (*b*; B and E) and handling time (*h*; C and F).
