A recent increase in jellyfish populations: A predator-prey model
and its implications.
Legovic, T
Ecological Modelling. Vol. 38, no. 3-4, pp. 243-256. 1987.
Factors that might have caused a recent increase of jellyfish
(Pelagia noctiluca ) populations in the Mediterranean sea are
investigated using a simple predator-prey model. Higher nutrient
inflow causes an increase in the steady state of a jellyfish
population and no change in the steady state of jellyfish prey.
Qualitatively the same change is obtained if the population of
predators competing for jellyfish prey is decreased. A decrease of
predators on the jellyfish population causes an increase in
jellyfish prey. Sufficiently high nutrient enrichment, or a
decrease in jellyfish competitors or predators, may cause the
appearance of a stable limit cycle, i.e., asymptotically periodic
fluctuations of both the jellyfish population and its prey.
