Your Name:EEMB/ES 171-Winter 2014 Quiz # 1 Read each question carefullyUse the back if you need to1. (6 points) What is soil texture? 2. (12 points). Why do ecosystem ecologists generally work with “functional groups” or “growthforms” of plants, rather than species? 3. (12 points). Briefly define the difference between Resistance and Resilience. Is the concept of resilience relevant in the face of ongoing increases in global temperature?Your Name:4. (16 points). ClORPT is an important formula in ecosystem science. A. (10) What do the letters stand for? Very briefly, why are they each important?ClORPTB. (6) If you were going to design a large-scale field experiment to analyze the influence of parent material on ecosystem structure and function, how would you use the ClORPT concept to guide developing that experiment? 5. (12 points) Many plants are highly tolerant of aboveground herbivory. They get between 50 and 90% of their leaves eaten and they grow back quickly. However, very few plants are tolerant of belowground herbivory. They get 20-25% of their root system eaten and they die. Why do youthink there is such a strong difference in responses to above and belowground herbivory?Your Name:6. (14 points) Match up the specific ecological/hydrological terms with their closest analogies from economics and life:A) AET Monthly Income B) PET Credit card billC) Rainfall An inheritance from a rich uncleD) Soil water storage Actual payment to the credit card companyE) Groundwater Aquifer Size of your savings account Briefly explain each analogy.7. (14 points total? Or 8?). You are doing a water balance on an area. The following values are for the summer only. Briefly explain your answers.PET = 1200 mmRainfall = 1600 mmSoil water holding capacity = 300 mmSoil water at the beginning of summer = 100 mma) (8 points) What is AET for this summer? b) (6 points?) What is streamflow?Your Name:8. (14 points) You are studying the productivity of a particular plant. You set up a factorial experiment with treatments of added nitrogen (N), phosphorus (P), and N+P plus a control. Then you measure growth. The data is in the table. Unfortunately, your research assistant lost one set of samples.Treatment Growth (g)Control 5+N 8+P Lost data+N +P 12A. (8 points) If Liebig’s Law were strictly true for this plant, what would you predict that growth in the +P treatment would be? Why?B. (6 points) Your technician goes back to his lab notes, and says that he thinks the growth data for the P treatment was 10. How would that change your interpretation of the nutrient needs of this plant? What would that say about Liebig’s
