Please take a look at the video lessons on The Scientific Way of Thinking to understand how VERA supports scientific modeling.

Spotted Tailed Quoll (323726)

Welcome to the Virtual Ecological Research Assistant (VERA)

This is a simplified model of a food web that involves Dasyurus maculatus (Spotted-tailed quoll), Trichosurus caninus (Mountain brushtail possum), and Insecta (Insects) generated from the Encyclopedia of Life.

VERA is a tool for modeling and experimenting with ecological systems like the one you see here, and we invite you to try it out!

In the simulation graph, you will see a collapsed ecosystem where Spotted-tailed quoll and Mountain brushtail possum both die of starvation.

In VERA, you can increase the food source by increasing the population size of insecta (Insects) or increasing the consumption rate and interaction probability between the predators and prey.

In order to start exploring this ecosystem, you will either need to log in if you already have an account, or sign up for one if you don't have one yet.
