Present four general causal loop diagrams (CLDs), one each for the four phases of the spread of nonnative forest insects and pathogens: Absent, Localized, Spreading, and Pervasive (see Lovett et al. Fig 2).

For each diagram depict the appropriate policy(ies) that would reduce impacts.

Limit the number of elements to 10 for all four CLDs.

Provide supporting background discussion of the diagram, the technical viability of the policy, and the costs implications.

Draw from your readings and class discussion. As noted in the Homework 2 rubric, this essay must focus on one nonnative species. Please note that Lovett provides a robust treatment of the absent and localized phases, but that additional research will be necessary to provide a balanced approach to all four phases.

Please use the Kumu tool to draw your CLDs.

Submission: Maximum paper length including diagrams but not references: 10 pages, double-spaced, 12-point font, minimum of 5 references, APA citation style.

Read the Coefficient of Drag write-up in the lab manual. Answer these questions either on a print-out of this sheet or in your lab notebook. I will initial them and grade them 0/0.5/1 based on whether they are complete and correct as usual. Neatly tape/staple them into your lab notebook with the correct lab entry.

1. Why are coffee filters used in this experiment?

2. How is the position of the coffee filter(s) as a function of time measured?

3. Sketch the velocity vs. time graph you expect to get from the Capstone software and indicate how you will know terminal velocity has been reached?

4. When we make our graphs in excel, what quantity are we ultimately trying to determine, and how do we get it?

5. Why do we use the logarithms in our analysis of the data?

Our discussion of ethics has been mostly about ethical norms within the world of science, but what about ethical issues that are related to science? Attached is an article with 10 of the most pressing moral dilemmas that relate to the world of science. Read through these 10 short pieces, choose ONE issue and read it carefully, and then write a short personal response on that ethical issue. First, tell me which ethical article you are responding to (the title will suffice), and then tell me how that article helped you to think about the ethical issues discussed. Then, tell me what your position is on that issue along with why you have that position (defend your stance). Please write in complete thoughts, with full sentences and paragraphs. Your writing should be about 2 paragraphs long.

Question 1:

Discuss metabolic scaling. Think about all factors that contribute to metabolism and how these change with body size. For simplicity, use the prairie dog and bison as your examples.

Question 2:

Think about the organelles, the cells, and the tissues used in maintaining endothermic body temperatures. How are these different in a slow-moving sloth versus a cheetah that need burst of energy to chase prey?

Question 3:

Explain how the nervous system works. Start with the resting potential, describe a stimulus, and continue until the signal has affected a motor neuron. Be very specific.

Question 4:

We have discussed the blubber in whales a few times. With regard to the topics discussed, how does the breeding season fast affect whales and their blubber. Consider all physiological relevant topics.
