Allee Effect: Population Extinction Threshold

Interactive 3D Allee-effect simulator: watch a wildlife population grow toward carrying capacity or collapse to extinction depending on whether it sits above or below a critical threshold density, with live population dynamics and a real-time trajectory chart.

Most population-growth simulators show logistic growth, where a small population always recovers. Real wildlife populations often don't work that way: below a critical density, mate-finding failure, loss of cooperative defense, and inbreeding depression push growth rate negative, sending the population to extinction even with no outside pressure. This simulator renders a live 3D colony whose individuals wander a bounded habitat, growing and thinning in real time according to the strong Allee effect equation. Adjust the growth rate, Allee threshold and carrying capacity, or use the cull and reintroduction buttons to push the population across its threshold and watch whether it recovers toward carrying capacity or spirals to extinction — with a live trajectory chart tracking the exact tipping point.
