Overview
The Lotka-Volterra equations describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The populations fluctuate in a regular cycle.

Pro Tips
Try the 'Stable' preset to see a classic balanced ecosystem cycle.
Switch to 'Phase Orbit' to visualize the limit cycles of the populations.
Adjust the 'Prey Birth Rate (α)' to see how fast reproduction affects stability.

Fun Facts
"The equations were independently proposed by Alfred J. Lotka in 1925 and Vito Volterra in 1926."
"These non-linear differential equations are a pair of first-order, non-linear, ordinary differential equations."
"The model makes several simplifying assumptions, such as the prey population having ample food at all times."
