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

Human (327955)

Welcome to the Virtual Ecological Research Assistant (VERA)

This is a simplified model of a food web that involves Homo sapiens (Human), Limanda aspera (Yellowfin sole), Sebastes maliger (Quillback Rockfish), and Telmessus cheiragonus 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 Human that consumes Yellowfin sole and Quillback rockfish dies off, and Yellowfin sole and Quillback rockfish that consume Telmessus cheiragonus (a species of True crab) grow fast.

In VERA, you can increase the consumption rate and interaction probability between Human and Yellowfin sole to see how it affects the ecosystem.

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.
