From: Filial cannibalism of Nabis pseudoferus is not evolutionarily optimal foraging strategy
Our model was run with the following real parameters: \(y=16.8\); \(b=0.44\); \({\tau }_{a}=23.3\); \({\tau }_{b}=16.6\); \({\tau }_{s}=5.3\); \({k}_{3}=1.00\); \({k}_{4}=0.80\); \({k}_{5}=0.55\); \({a}_{3}=0.91\); \({a}_{4}=3.00\); and \({a}_{5}=6.14\): In the left panel of Fig. 2, we calculate the life reproductive success \({\text{X}}\) as a function of different prey preferences. We find that it takes its maximum at the optimal cannibalistic rate \({P}_{A}= 0.1717\) and the optimal heterospecific prey consumption rate \({P}_{B}=1\), with \(X\left(0.1717, 1\right)=5.2679\) E \(+02.\) In the right panel, we calculate the reproductive season growth rate Z as a function of different prey preferences. We find that the optimal cannibalistic rate is \({P}_{A}= 0\) and the optimal heterospecific prey consumption rate is \({P}_{B}=1\), and the maximum is \(Z\left(0, 1\right)= 1.3209\) E \(+17.\)
