Complex oscillatory patterns in a three-timescale model of a generalist predator and a specialist predator competing for a common prey
Susmita Sadhu
In this paper, we develop and analyze a model that studies the interaction between a specialist predator, a generalist predator, and their common prey in a two-trophic ecosystem fe…
Complex oscillatory patterns near singular Hopf bifurcation in a two time-scale ecosystem
Susmita Sadhu
We consider an ecological model consisting of two species of predators competing for their common prey with explicit interference competition. With a proper rescaling, the model is…
Stochasticity induced mixed-mode oscillations and distribution of recurrent outbreaks in an ecosystem
Susmita Sadhu
The effect of stochasticity, in the form of Gaussian white noise, in a predator-prey model with two distinct time-scales is presented. A supercritical singular Hopf bifurcation yie…
Stochastic mixed-mode oscillations in a three-species predator-prey model
Susmita Sadhu, Christian Kuehn
The effect of demographic stochasticity, in the form of Gaussian white noise, in a predator-prey model with one fast and two slow variables is studied. We derive the stochastic dif…
