Mathematics, 2023 Harvesting is one of the ways for humans to realize economic interests, while unrestricted harvesting will lead to the extinction of populations. This paper proposes a predator–prey model with impulsive diffusion and transient/nontransient impulsive ...

Stabilization for a Periodic Predator-Prey System [PDF]
Abstract and Applied Analysis, 2007 A reaction-diffusion system modelling a predator-prey system in a periodic environment is considered. We are concerned in stabilization to zero of one of the components of the solution, via an internal control acting on a small subdomain, and in the preservation of the nonnegativity of both components.

Modelling the dynamics of traits involved in fighting-predators–prey system [PDF]
, 2015 We study the dynamics of a predator–prey system where predators fight forcaptured prey besides searching for and handling (and digestion) of the prey. Fighting for prey is modelled by a continuous time hawk–dove game dynamics where the gain depends on ...

Transport of inertial particles by Lagrangian coherent structures : application to predator-prey interaction in jellyfish feeding [PDF]
, 2009 We use a dynamical systems approach to identify coherent structures from often chaotic motions of inertial particles in open flows. We show that particle Lagrangian coherent structures (pLCS) act as boundaries between regions in which particles have ...

Predator confusion is sufficient to evolve swarming behavior
, 2013 Swarming behaviors in animals have been extensively studied due to their implications for the evolution of cooperation, social cognition, and predator-prey dynamics.

Evolutionary tradeoff and equilibrium in an aquatic predator-prey system [PDF]
, 2004 Due to the conventional distinction between ecological (rapid) and evolutionary (slow)timescales, ecological and population models to date have typically ignored the effects of evolution.

Permanence for nonautonomous predator-prey systems
Differential and Integral Equations, 1991 This paper concerns the question of permanence for general predator-prey models. The authors have shown that at least for two species models, a rather natural condition for permanence may be obtained. It is shown, by using an ``average'' Lyapunov function technique, that an average condition on the predator growth rate ensures that permanence holds.

Evolution of Lotka-Volterra predator-prey systems under telegraph noise
Mathematical Biosciences and Engineering, 2009 In this paper we study a Lotka-Volterra predator-prey system with prey logisticgrowth under the telegraph noise. The telegraph noise switches at random two prey-predator models.

Evolutionary predator-prey robot systems
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2019 We present a feasibility study on evolving controllers for a group of wheeled robot predators that need to capture a prey robot. Our solution method works by evolving controllers in simulation for 100 generations, followed by 10 generations on real robots. The best controllers are further evaluated by their sensitivity for the initial positions.

Dynamics and pattern formation in diffusive predator-prey models with predator-axis
Electronic Journal of Differential Equations, 2020 We consider a three-species predator-prey system in which the predator has a stage structure and the prey moves to avoid the mature predator, which is called the predator-taxis.
