Understanding how tipping points arise is critical for population protection and ecosystem
robustness. This work evaluates the impact of environmental stochasticity on the emergence …

A significant degree of complexity to the conventional ecological dynamic is added by
studying prey–predator models with harvesting predators. The primary focus of classical …

We propose four predator–prey models: RM (Rosenzweig–MacArthur) model, BD model
(RM type model with Beddington–DeAngelis functional response), RMI model (ie, RM model …

Environmental pollution has led to many ecological issues, including air, water, and soil
contamination. Developing appropriate pollution control measures to mitigate these hazards …

In this paper, a predator–prey model with double Allee effect and self-diffusion terms is
considered. The stability of the coexisting equilibrium is studied by analyzing the eigenvalue …

In this paper, in order to explore the inhibition mechanism of algicidal bacteria on algae, we
constructed an aquatic amensalism model with non-selective harvesting and Allee effect …

A resource production–consumption model with crowding effect and sigmoidal consumption
pattern, subject to cross-correlated multiplicative and additive noises, is proposed in this …

Abstract Depending upon Lotka-Volterra model along with biological parameters,
intuitionistic fuzzy in nature, this paper deals with harvesting system of prey species and …

This paper analyzes the effect of fear in a Leslie-Gower predator-prey system with Holling
type IV functional response. Firstly, we show positivity and boundedness of the system. Then …

Field and experimental data on aquatic ecosystem species show the effect of fear on
changing prey demographics. The fear effect has an impact on aquatic ecosystems, such as …
