A predator-prey model with different response functions to juvenile and adult prey in deterministic and stochastic environments

作者:

Highlights:

• A predator-prey model with stage structure for prey in two cases is proposed.

• The deterministic case exhibits bistability and complex bifurcations.

• The stochastic case possesses a unique ergodic stationary distribution.

• Noise-induced state switching between two stochastic attractors is observed.

• Results partially show species may switch among different patterns of survival.
