  We study the Bazykin predator-prey model with predator intraspecific
interactions and ratio-dependent functional response and show the existence and
stability of two interior equilibrium points. We prove that the model displays
a wide range of different bifurcations, such as saddle-node bifurcations, Hopf
bifurcations, homoclinic bifurcations and Bogdanov-Takens bifurcations. We use
numerical simulations to further illustrate the impact changing the predator
per capita consumption rate has on the basin of attraction of the stable
equilibrium points, as well as the impact of changing the efficiency with which
predators convert consumed prey into new predators.
