Let's experiment

In this page, you have the opportunity to make experiments and to find answers to "what-if" questions.
In this ecosystem (in equilibrium) , there are five species : Lions , Zebras(20), Gnus(20), Short(500) and Long Grass(400).

Here are some suggestions that you can try out:

Make one species more or less resistant to hunger :
- Change the main parameter for the first predator
- Change the main parameter for the second predator
- Change the main parameter for the first herbivore
- Change the main parameter for the second herbivore
Change the initial populations of one or more species

Change the start time for some species.

Produce epidemics on some species ( parameters when, int and Ill ).
