Fractal and Fractional, 2023 This study examines the dynamics of a stochastic prey–predator model using a functional response function driven by Lévy noise and a mixed Holling-II and Beddington–DeAngelis functional response.

Effects of demographic noise on the synchronization of a metapopulation in a fluctuating environment [PDF]
, 2011 We use the theory of noise-induced phase synchronization to analyze the effects of demographic noise on the synchronization of a metapopulation of predator-prey systems within a fluctuating environment (Moran effect).

Persistent predator–prey dynamics revealed by mass extinction [PDF]
Proceedings of the National Academy of Sciences, 2011 Predator–prey interactions are thought by many researchers to define both modern ecosystems and past macroevolutionary events. In modern ecosystems, experimental removal or addition of taxa is often used to determine trophic relationships and predator identity. Both characteristics are notoriously difficult to infer in the fossil record, where evidence

Mammal predator and prey species richness are strongly linked at macroscales [PDF]
, 2013 Predator-prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large-scale gradients of species richness remains unexplored.

Positive symplectic integrators for predator-prey dynamics
, 2017 We propose novel positive numerical integrators for approximating predator-prey models. The schemes are based on suitable symplectic procedures applied to the dynamical system written in terms of the log transformation of the original variables.

Ecology and Evolution, 2023 Disease ecologists now recognize the limitation behind examining host–parasite interactions in isolation: community members—especially predators—dramatically affect host–parasite dynamics.

A piecewise deterministic model for a prey-predator community [PDF]
, 2016 International audienceWe are interested in prey-predator communities where the predator population evolves much faster than the prey's (e.g. insect-tree communities).

Prey–Predator Models with Variable Carrying Capacity
Mathematics, 2018 Prey–predator models with variable carrying capacity are proposed. These models are more realistic in modeling population dynamics in an environment that undergoes changes.

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.

Predator–prey dynamics with intraspecific competition and an Allee effect in the predator population
, 2017 The study of the Allee effect on the stability of equilibria of predator-prey systems is of recent interest to mathematicians, ecologists, and conservationists.
