Initial situation of the simulation
At the beginning, different lizards live together in one continuous habitat. At night foxes go hunting, while weasels search for prey during the day. Different predators therefore affect the population at different times of day. During the simulation, weather events can also occur that permanently change the habitat. Observe how this gradually changes the habitat and the composition of the population.
Task: Observe how the lizard population develops over the course of the simulation. Pay attention to how predators, times of day, and weather events affect the two habitats and the composition of the population. At the end, export the simulation result and analyse the charts.

Decision: what happens next?
After several stable cycles, the situation becomes more critical. You decide which event permanently changes the environment.
Severe thunderstorm
Dark clouds, heavy rain, and lightning: the area is reshaped, scree is exposed, and the conditions change abruptly.
Wildfire
Dry vegetation catches fire: the fire spreads, charring the landscape and leaving it dark in the long term.
The simulation pauses until you make a choice.
A flash flood
Because of climate change, ice surfaces melt faster. More meltwater and heavier rainfall create a river.
The previously continuous habitat is split into two separate habitats.
Click Rain to trigger the event.
Simulation complete - save results
You can now export the results. Please export the charts, then start another run with a different weather event than in run 1 and compare the results of both runs.
