ne of the first papers published on keystone species was by Robert Paine who studied sea stars (starfish) in the intertidal region. The paper has a short easy to read results section detailing all of the different experiments that were carried out Read the complete paper and complete the following: 1. Examine Figure 1. construct a food web like that of Figure 1 except with drawings. State the experimental hypothesis of the author. Describe what it means for a species to monopolize a major environmental requisite. Research each animal you are not familiar with and on a separate sheet of paper 2. Deseribe Paine’s experimental set-up in Mukkaw Bay. If you were to recreate this experiment and had an unlimited stretch of intertidal coast to work with, identify TWO modifications to the experimental design that would improve this experiment. 3. On pages 67 & 68, the author details some of the difficulties in constructing the food webs and determining the hierarchies. What complexity created a problem(s)? 4. 5. The summary of the paper has this statement: Where predators capable of preventing monopolies are missing, or are experimentally removed, the systems become less diverse.” Explain in your own words what this statement means. 6. On page 69, the author details “A tropical subweb.” a. b. e. What are muricid gastropods? The author makes the statement: “No secondary carnivore was present.” What does this mean? How does this location’s biodiversity compare with other locations with sea stars? Does this make sense with the author’s conclusions from his experimental locations? Justify your answer
