When you have registered, a new page will open. On it you will see a list of virtual labs for this course. Select KEYSTONE PREDATORS. Be sure to print out a workbook; the instructions you need to follow so that the lab makes sense, will be in the workbook. There are many pages so you may want to print two pages to one sheet of paper and/or double sided; while small, the type is still legible.

Read the following sections:

Introduction and Starting Up.

DO the following activities:

Exercise 1: Flexing your mussels! This activity explores the relationships among sessile consumers. Which species are competitively dominant over others? You will construct a competitive dominance hierarchy diagram.  Answer the following questions on a separate document: 1.1, 5.1, 7.1, 9.1, & 10.

Exercise 2: You are what you eat! Explore what mobile consumers eat! You will create a food web showing this relationship. Answer the following questions on the same document you created to answer the questions above:  8.1, 8.2, 9.1

Exercise 3: Who rules the rock? In this activity you explore how removing higher trophic level species affect the community structure. In 10.1, where it says "be quantitative" that means to be specific, use numbers in your answer. Do the "Optional: Species Reintroduction" exercise; it is NOT optional. Answer the following questions on the same document you created to answer the questions above: 1.1, 1.2, 3.1, 6.1, 8.1, 9.1, 10.1, 10.2, 10.3, 10.4, 0.5, 10.6, 12.1, 13.1,16.1, 16.2
