🦊 Fox & Rabbits — Predator-Prey Simulation

Explore the classic predator-prey cycle: foxes hunt rabbits, rabbit populations crash, fox populations follow — the eternal oscillation described by the Lotka-Volterra equations.

🔬 What It Demonstrates

Population cycles emerge from simple rules: rabbits eat grass and reproduce; foxes eat rabbits and die if they can't find food. The boom-and-bust cycles match what ecologists observe in real ecosystems like the Canadian lynx-hare system.

🎮 How to Use

Watch the population graph. Adjust birth rates, death rates, and hunting efficiency with sliders. Try exterminating foxes — watch the rabbit population explode, then collapse from overgrazing.

💡 Did You Know?

The Hudson's Bay Company recorded lynx and snowshoe hare pelt numbers from 1845 to 1935, showing near-perfect 10-year oscillation cycles — one of the longest datasets confirming the Lotka-Volterra model.

⚙ Under the hood

Explore how fox populations impact rabbit numbers in a virtual ecosystem; manipulate birth and hunting rates to see the dynamic predator-prey interaction unfold.
