Population Dynamics

Food webs can evolve over time, in cycles and permanently. Predator-prey relations are an example of changes in the components of the food web over time. For example, if the population of predators grows too much, then over predation will occur. Consequently, the population of the prey falls, and can no longer support such a large population of predators. The population of predators falls, resulting on less pressure on the prey population, which then recovers. This cycle can repeat itself many times, as expressed in the Lotka-Volterra Predatory-Prey model (shown below in a systems dynamics process). Such Predator-Prey cycles occur in human economies as well.

Click on the “Simul…” button to run the below simulation of the relation between a moose and wolf population where wolves prey on moose. Feel free to explore additional settings and options. You can even create your now account on the underlying Insightmaker platform and create your own simulations.
