  Small and large scale pandemics are a natural phenomenon repeatably appearing
throughout history, causing ecological and biological shifts in ecosystems and
a wide range of their habitats. These pandemics usually start with a single
strain but shortly become multi-strain due to a mutation process of the
pathogen causing the epidemic. In this study, we propose a novel
eco-epidemiological model that captures multi-species prey-predator dynamics
with a multi-strain pandemic. The proposed model extends and combines the
Lotka-Volterra prey-predator model and the Susceptible-Infectious-Recovered
(SIR) epidemiological model. We investigate the ecosystem's sensitivity and
stability during such a multi-strain pandemic through extensive simulation
relying on both synthetic cases as well as two real-world configurations. Our
results are aligned with known ecological and epidemiological findings, thus
supporting the adequacy of the proposed model in realistically capturing the
complex eco-epidemiological properties of the multi-species multi-strain
pandemic dynamics.
