1. CLEARLY draw what might happen to the following graph if by some catastrophic event the human population was cut in half. The blank graph picks up where the first one leaves off. Use the space below to explain why you drew what you did. (10 points)

2. In the notes I described conservation as the act of trying to preserve the land’s capacity for self-renewal (Actually I borrowed this from Aldo Leopold). Explain what this means in your own words. Use examples if that helps. (5 points)

Gross Domestic and Gross National Product are common measures of economic growth, but are criticized by conservationists because…

How are the concepts of “supply-demand” and a “market economy” related?

What might be a problem in letting the market dictate resource management?

Okay, here’s a break from writing. Match the following with the appropriate statement. Each statement should have only one answer but if you think more than one applies or if the correct on isn’t there let me know. (6 points)

A.Genuine Progress IndicatorB.Green TaxC.Lifestyle TaxD.SubsidiesE.Market BarrierF.Economic Incentives

_________ Incorporates the costs of pollution cleanup into measures of economic growth

_________Increases the costs of environmentally friendly practices in manufacturing, or other sectors

_________Placing a significantly greater tax on low mileage vehicles

_________Taxes placed on natural resources

_________Pays producers to support the costs of growing or producing products such as crops

_________Tax cuts to reward environmentally friendly practices.

1. Earth has limited resources2. Humans are part of nature3. Key is to cooperate with nature4. Natural systems are essential for

the existence of life on Earth

1. Conservation2. Recycling3. Renewable resource use4. Restoration, preservation5. Population control

5. A and B should look fairly familiar. In your own words write a nice neat paragraph (with complete sentences, punctuation etc.) to show me you understand the items in A and suggest some ways the strategies in B (or others) can be used to address problems in A. I’m not looking for definitions but explanation which shows me you understand the concepts enough to discuss them in your own words. (25 points)

Shoot for at least 8-10 good sentences at least (more if you need but don’t try to baffle me with b.s.) Use space on the next page if needed. If you use the back of a page make a note so I know this.

HINT—each term above should show up in a meaningful way in your paragraph.

A B

____6. An ecosystem is composed of which of the following?

a. populations of different species of organismsb. all plant and animal life in a given areac. living communities and their physical environmentd. biomes

____7. Which would NOT be considered a component of biodiversity in an ecosystem?

a. genesb. nutrient cyclesc. the number of speciesd. community interactionse. none of the above

_____9. Which of the following is NOT likely a service ecosystems provide?

a. filter uv and other high energy wavelengths from sunlightb. nutrient cyclingc. capture sunlight energy and cycle it into the food chaind. water cycling

Multiple choice: 1 point each

10. A habitat generalist, a habitat specialist and an invasive species walk into a bar…

No wait, I mean they find themselves living in the same area—such as a recently developed forest in (where else?) the Southeastern U.S.

In general terms (since I’m not giving you specifics) what is likely to happen to each population (the generalist, specialist and invasive?) when they occur in the same area and have similar habitat requirements? Explain?

NOTE: There are a number of ways you can answer this and many of them will be “correct” What I’m looking for is that you can apply basic principles of ecology to justify your answer. (12 points)

11a. The essay “Thinking Like a Mountain” described changes in populations of wolves, deer, and plants. In the graph below, show me generally (I don’t need numbers) how changes in 1 population can lead to changes in the other 2. You don’t have to have read the essay to answer this question. It was an example. Use wolves, deer and plants if you like but use others if you choose. Just be able to explain and label graph. (10 points)

11b. Would it be fair to say that the changes in plant populations in the essay were ultimately caused by humans? Explain. (4 points)
