Starting Up

1 Read the introductory sections of the workbook, which will help you understand what’s going on in the simulation and answer questions.

2 Start SimBio Virtual Labs™ by double-clicking the program icon on your computer or by selecting it from the Start Menu.

3 When the program opens, select the Isle Royale lab from the EcoBeaker suite.

When the Isle Royale lab opens, you will see several panels:

← The ISLAND VIEW panel (upper left section) shows a bird’s eye view of northeastern Isle Royale, which hosts ideal moose habitat.

← The DATA & GRAPHS panel to the right displays a graph of population sizes of moose and wolves through time.

← The SPECIES LEGEND panel above the

Grass starts out as the most abundant plant species, but is soon replaced with maple and balsam fir trees. The Isle Royale simulation incorporates simplified vegetation succession to mimic the more complex succession of plant species that occurs in the real world. After about 5 simulated years, the first moose swim over to the island from the mainland and start munching voraciously on the plants.

6 You can zoom in or out using the Zoom Level Selector at the top of the ISLAND VIEW panel. Click different Zoom Level circles to view the action up closer or further away. After watching for a bit, click on the left circle to zoom back out. You can zoom in and out at any time.

7 Reset the simulation by clicking the RESET button in the Control Panel. Confirm that the simulation has been reset by checking that the Time Elapsed box to the right of the Control Panel reads “0 Years”.

8 Click the STEP 50 button on the Control Panel, and the simulation will run for 50 years and automatically stop. Watch the graph to confirm that the size of the moose population changes dramatically when the moose first arrive, and then eventually stabilizes (levels out).

← You can adjust how fast the simulation runs with the SPEED slider to the right of the control panel. 9 Once 50 years have passed (model years — not real years!), examine
