Predator-prey cycles from resonant amplification of demographic stochasticity

, 2005
In this paper we present the simplest individual level model of predator-prey dynamics and show, via direct calculation, that it exhibits cycling behavior.

Permanence and Extinction of Regime-Switching Predator-Prey Models [PDF]

SIAM Journal on Mathematical Analysis, 2015
In this work we study the permanence and extinction of a regime-switching predator-prey model with the Beddington--DeAngelis functional response. The switching process is used to describe the random changes of corresponding parameters such as birth and ...

Stable scalable control of soliton propagation in broadband nonlinear optical waveguides

, 2017
We develop a method for achieving scalable transmission stabilization and switching of $N$ colliding soliton sequences in optical waveguides with broadband delayed Raman response and narrowband nonlinear gain-loss.

A fractional B-spline collocation method for the numerical solution of fractional predator-prey models [PDF]

, 2018
We present a collocation method based on fractional B-splines for the solution of fractional differential problems. The key-idea is to use the space generated by the fractional B-splines, i.e., piecewise polynomials of noninteger degree, as approximating

The mechanics of predator-prey interactions: first principles of physics predict predator-prey size ratios

bioRxiv, 2018
Robust predictions of predator-prey interactions are fundamental for the understanding of food webs, their structure, dynamics, resistance to species loss and invasions and role in ecosystem functioning. Most current food web models are empirically based.

Predator–prey interaction in insects and arachnids: a chemical ecology perspective

Academia Environmental Sciences and Sustainability
Animals emit distinctive semiochemicals—chemical substances that mediate interactions between organisms—and many of them have evolved means to detect and respond to these chemicals emitted by others.

Diverging fluctuations in a spatial five-species cyclic dominance game

, 2013
A five-species predator-prey model is studied on a square lattice where each species has two prey and two predators on the analogy to the Rock-Paper-Scissors-Lizard-Spock game.

Self-optimization, community stability, and fluctuations in two individual-based models of biological coevolution

, 2007
We compare and contrast the long-time dynamical properties of two individual-based models of biological coevolution. Selection occurs via multispecies, stochastic population dynamics with reproduction probabilities that depend nonlinearly on the ...

Spatio-temporal dynamics of a predator–prey system with variable carrying capacity and Cosner response function

Franklin Open
The environmental carrying capacity plays a major role in population dynamics and is highly unpredictable in predator–prey relationships. In this study, we examine a predator–prey model with logistic growth rate and variable carrying capacity of prey ...
