BRIDGING CAPTIVE AND WILD STUDIES: BEHAVIORAL PLASTICITY AND SOCIAL COMPLEXITY IN THEROPITHECUS GELADA




Hopf bifurcation and stability in a Beddington-DeAngelis predator-prey model with stage structure for predator and time delay incorporating prey refuge

In this paper, we consider a Beddington-DeAngelis predator-prey system with stage structure for predator and time delay incorporating prey refuge.By analyzing the characteristic equations, we study the local stability of the equilibrium of the system.Using the delay as a bifurcation parameter, the model undergoes Baby Feeding a Hopf bifurcation at
