Summary

This study examines a prey-predator model with parasite infection. Introducing a delay in the system was found to destabilize the predator-prey dynamics, impacting population persistence.

Area of Science:

  • Mathematical Biology
  • Ecology
  • Epidemiology

Background:

  • Parasitic infections can significantly alter host population dynamics.
  • Prey-predator interactions are fundamental ecological processes.
  • Functional responses describe predator feeding rates based on prey availability.

Purpose of the Study:

  • To analyze a mathematical model of a prey-predator system with parasitic infection.
  • To investigate the impact of parasite infection on both prey and predator populations.
  • To determine the criteria for population persistence and extinction within this system.

Main Methods:

  • Development of a mathematical model for the prey-predator system.
  • Analysis of population persistence and extinction criteria.
  • Investigation of the stability of the interior equilibrium point.
  • Incorporation and analysis of time delay in the system dynamics.
  • Verification of results through computer simulations.

Main Results:

  • Derived criteria for the persistence and extinction of prey and predator populations.
  • Discussed the stability of the interior equilibrium point.
  • Identified the destabilizing effect of time delay on the system.
  • Predator functional response modeled as a weighted sum of prey abundances.

Conclusions:

  • Parasitic infection influences prey-predator dynamics.
  • Time delays can introduce instability into ecological models.
  • The model provides insights into the complex interactions within infected ecosystems.
