    22 Pj is limited to the range [0,2]. While See "aij(t) = !KijaijBi(t)Pj / Σi’ai’jBi ’(t)Pj Eq. 55" is derived by pretending that predators must allocate time among mutually exclusive foraging arenas for each of their prey types (a typically unrealistic assumption), it can still be used (with Pj <<1 values) to represent more general ideas about why and how predators switch among prey, e.g. formation and loss of search images for finding them.

    2424Impact of setting a positive switching power parameter can be exemplified based on migratory striped bass. In this example switching results in much more variable for the predator – which simulation is the more appropriate can only be determined from empirical information (Figure 3.11).
