Part I – Barnacle competition

Go to http://virtualbiologylab.org/community-ecology/

After reading the background and tutorial, click to run the experiments.

1-At the end of Day 1, click pause.Take a screenshot of the data table summarizing the local abundance, mean elevation on rock and standard deviation.Paste your table here:

2-Increase the sea level to 1 m, and run the experiment for Day 2. At the end of Day 2, click pause.Take a screenshot of the data table summarizing the local abundance, mean elevation on rock and standard deviation to show how they changed.Paste your table here:

3-Reduce the density of Thais to 1, and run the experiment for Day 3. At the end of Day 3, click pause.Take a screenshot of the data table summarizing the local abundance, mean elevation on rock and standard deviation to show how they changed.Paste your table here:

4-Increase the density of Thais to 3, and run the experiment for Day 4. At the end of Day 4, click pause.Take a screenshot of the data table summarizing the local abundance, mean elevation on rock and standard deviation to show how they changed.Paste your table here:

5-Manipulate at least one other combination of parameters that you can think of.Take a screenshot of the data table summarizing the local abundance, mean elevation on rock and standard deviation to show how they changed.Paste your table here:

Summarize your findings by answering the questions below.

6-How does increasing the sea level affect each species of barnacle?

7-How are the barnacles affected when Thais density changes?

8-What implications could this have for the ecosystem?

Part II – Biome Investigation
