In biological control programs, the provision of additional food is regarded as one of the
most useful tools for species conservation and pest management. In a system, providing …

In this paper, we report the discovery of some novel dynamical scenarios for quasi-periodic
shrimp-shaped structures embedded within chaotic phases in bi-parameter space of a …

Plankton-fish interactions are the central topic of interest related to marine ecology. Apart
from the direct predation (lethal effect) of zooplankton by fish, there are some non-lethal …

Multistability is an inherent property of many nonlinear dynamical systems. However, finding
exact conditions where a certain nonlinear system is multistable, is a complex problem. In …

We report the existence of periodic structures viz., Arnold tongues, and shrimp-shaped
structures in the transitional and chaotic regimes in bi-parameter spaces of a predator–prey …

Classical predator–prey models usually emphasize direct predation as the primary means of
interaction between predators and prey. However, several field studies and experiments …

In this paper, we consider a nonlinear ratio-dependent prey–predator model with constant
prey refuge in the prey population. Both Allee and fear phenomena are incorporated …

Aside from humans, the instinct to run and hide from dangerous situations is ingrained in
individuals of many other species. Taking refuge is a very common precautionary strategy …

The environmental characteristics of a biological system are imbibed in some particular
parameters of that system. Significant changes in any system parameter exert influence on …

The simplest megastable chaotic system is built by employing a piecewise-linear damping
function which is periodic over the spatial domain. The unforced oscillator generates an …
