Delayed stability switches in singularly perturbed predator-prey models [PDF]
, 2016 In this paper we provide an elementary proof of the existence of canard solutions for a class of singularly perturbed predator-prey planar systems in which there occurs a transcritical bifurcation of quasi steady states.

Fractal and Fractional, 2020 In this work, a fractional predator-prey model with the harvesting rate is considered. Besides the existence and uniqueness of the solution to the model, local stability and global stability are experienced.

A predator-prey interaction between a marine Pseudoalteromonas sp. and Gram-positive bacteria
Nature Communications, 2020 Predator-prey interactions play important roles in the cycling of marine organic matter. Here we show that a Gram-negative bacterium isolated from marine sediments (Pseudoalteromonas sp.

Attraction and Avoidance between Predators and Prey at Wildlife Crossings on Roads
Diversity, 2020 Wildlife passages are currently built at roads and railway lines to re-establish connectivity. However, little is known about whether predator-prey interactions may reduce the effectiveness of the crossing structures.

Journal of Applied Mathematics, 2022 In this paper, we present and analyze predator-prey system where prey population is linearly harvested and affected by fear and the prey population has grown logistically in the absence of predators.

Bistability induced by generalist natural enemies can reverse pest invasions [PDF]
, 2016 Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth.

Prey and predator density‐dependent interactions under different water volumes
Ecology and Evolution, 2021 Predation is a critical ecological process that directly and indirectly mediates population stabilities, as well as ecosystem structure and function. The strength of interactions between predators and prey may be mediated by multiple density dependences ...

Dynamical study of the theta-logistic predator-prey model incorporating gregarious behavior of prey
Mathematics in Applied Sciences and Engineering, 2023 Relation between species and their livelihood environment in ecological systems is very complex. For that reason, in order to study predator-prey relations, modeling is essential in biomathematics.

Applying allometric scaling to predator-prey systems [PDF]
, 2019 In population dynamics, mathematical models often contain too many parameters to be easily testable. A way to reliably estimate parameters for a broad range of systems would help us obtain clearer predictions from theory.
