The '''Lotka-Volterra equations''' are a pair of first-order nonlinear differential equations that describe the interaction between two species in a biological system: a predator and its prey. Developed independently by Alfred Lotka (1925) and Vito Volterra (1926), the model assumes that prey grow exponentially in the absence of predators, predators decline exponentially in the absence of prey, and encounters between the two produce predator growth and prey death at rates proportional to their product.

The equations produce two striking behaviors. First, they predict perpetual oscillation: predator and prey populations cycle in eternal recurrence, with peaks in prey abundance followed by peaks in predator abundance. Second, the oscillation amplitude depends on initial conditions — a signature of the model's nonlinear structure. In state space, the trajectories form closed orbits around a central fixed point, making the Lotka-Volterra system one of the simplest [[Dynamical systems|dynamical systems]] to exhibit [[Limit Cycle|limit-cycle]]-like behavior.

The model is foundational to theoretical ecology and has been generalized to multi-species food webs, competitive interactions, and epidemic dynamics. Its central limitation — the assumption of exponential growth in isolation — makes it qualitatively wrong for most real populations, which are resource-limited. Yet the oscillatory structure it reveals persists in more realistic models, suggesting that the Lotka-Volterra equations capture something structural about predator-prey interaction that transcends their specific assumptions.
