About Ecological Niches: Choose the right Kuppelfang to bring to Earth! Virtual Lab Simulation

What if you could have your own cute little alien to pet? How would you know the requirements to keep it alive? In this simulation, you will learn to identify the fundamental niche of any species using Kuppelfangs as an example. This rock-digesting species from Astakos IV couldn’t survive when it was transplanted to a biodome on Earth. You will perform different experiments to understand what caused Kuppelfangs to die in the biodome and ultimately suggest a solution that will enable the species to survive on Earth.

Explore Astakos IV to collect data on a Kuppelfang’s fundamental niche

You will visit the three main regions where Kuppelfangs live on Astakos IV and collect soil samples that will provide information about their realized ecological niche. You will analyze three main variables that affect the survival of Kuppelfangs: temperature, soil pH and soil silicon concentration.

Learn to use n-dimensional hypervolumes and design your own experimental setup

After your field trip, you will measure the pH of the soil samples and determine its silicon concentration using HPLC. You will then plot and visualize your results in a 3-dimensional graph in order to compare the Kuppelfangs’ fundamental and realized niches with the niche found inside Earth’s biodome. After discovering the fundamental niche of Kuppelfangs, you will design an experiment using the three variables you have already measured and let baby Kuppelfangs grow in a greenhouse for one year. Following this step, the simulation will fast forward time so that you can see whether the Kuppelfangs survived in each environment. You will then take some individuals to the lab so that you can measure how certain physical features are related to specific environmental conditions.

Decide the best conditions for the Kuppelfangs’ survival on Earth

At the end of the experiment, you will determine how acclimation can expand and affect the boundaries of a niche. Will you be able to determine why the first Kuppelfangs sent to Earth’s biodome died? Can knowledge of their fundamental niche help you to develop a solution to ensure the Kuppelfangs’ survival in Earth’s biodome?
