An ecosystem shifts to an alternative stable state when a threshold of accumulated pressure
(ie direct impact of environmental change or human activities) is exceeded. Detecting this …

This work combines the issues of a time-varying biological system with the supply chain
management under one umbrella of the “dynamic biological supply chain management” …

Intense harvesting and emerging infectious diseases are potential threats to global fishery. A
proper management policy equipped with the scientific understanding of species interaction …

The management of predator-prey systems, particularly those with discontinuous harvesting,
plays a crucial role in maintaining ecological balance and ensuring the sustainable use of …

Though overfishing and climate change are the primary reasons for a regime shift in the
fishery, we demonstrate here a different reason for the regime shift, not reported earlier to …

Ecological balance and stable economic development are crucial for the fishery. This study
proposes a predator–prey system for marine communities, where the growth of predators …

The bifurcation analysis of a predator-prey system with Holling-II functional response
function and constant-yield predator releasing rate is carried out in this paper, which is a …

In this paper, a discrete predator-prey model with prey refuge is investigated. It is proved that
the model undergoes codimension-2 bifurcations associated with 1: 2 and 1: 3 resonances …

In this paper, we propose a diffusive predator–prey model with two delays, ie, a spatial
memory delay and a toxic effect delay. Initially, we analyze the global existence of the …

The current paper investigates a prey-predator-scavenger fishery model in which both prey
and predator species release harmful toxins during predation interaction. The harvesting of …
