Predator prey population cycles

WebThe prey population drops first and is followed with a lag by the predator population. The prey population then recovers first, followed by the recovery of the predator population. Image credit: Repeating cycles of growth and decline by CK-12 Foundation, CC BY-NC 3.0 WebAs prey become scarce then the predator population size declines and the cycle starts again. These intuitive dynamics can be captured by one of the simplest mathematical descriptions of a predator–prey interaction: the Lotka–Volterra model …

Lotka–Volterra equations - Wikipedia

The Lotka–Volterra equations, also known as the predator–prey equations, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The populations change through time according to the pair of equations: WebA simple model of a system with one species each of predator and prey, the Lotka–Volterra equations, predicts population cycles (Goel et al. 1971). However, attempts to reproduce the predictions of this model in the laboratory have often failed; for example, when the protozoan Didinium nasutum is added to a culture containing its prey, Paramecium …
