🦊 Fox and Rabbits — Ecosystem

A live Lotka-Volterra predator-prey ecosystem. Rabbits graze, multiply and are hunted by foxes. Watch the population chart oscillate as boom-and-bust cycles play out in real time.

🔬 What It Demonstrates

Agent-based simulation where each animal follows simple rules: eat, reproduce, die. Global population dynamics emerge from individual behaviours.

🎮 How to Use

Watch rabbits multiply, attracting foxes. As foxes overeat, prey declines, then foxes starve. The cycle repeats endlessly — a living demonstration of ecological balance.

💡 Did You Know?

The classic example is the Canadian lynx and snowshoe hare, whose fur-trapping records from the Hudson's Bay Company show 9-10 year population cycles going back to the 1800s.
