A) quantity B) contours C) migration rates and paths D) function 3. __B___ Sagebrush (Artemesia tridentata), a plant that can tolerate droughty, unfertile soils in the intermontane West of the United States, is an example of which of the ways to characterize biota that we discussed in class?

E) All of the above Geog 1403Spring 2010Exam 1cpage 2 Part II: Map questionsChoose the best answer (one point each) 11. __T___ Which of the following places on the map [T, 19, 21, 26] is near an area of extensive wetlands? 12. __M___ Which of the following places on the map [M, P, U, 9] is a location closest to the hardwood (broadleaf deciduous) forest biome? 13. __56___ Which of the following places on the map [M, 15, 49, 56] is closest to the location of the Wallace Line? 14. __31___ Which of the following places on the map [30, 31, 43, 58] has the lowest productivity (of the choices given) in the ocean? 15. __B___ Which of the following places on the map [B, W, 7, 28] is a location where cone-shaped trees shed snow and ice, and needle leaves tolerate the short growing season? Geog 1403Spring 2010Exam 1cpage 3 Part III: Essay questionsPlease provide concise yet complete answers. Write in full sentences to answer the following: 16. How are the chaparral (Mediterranean) biome and the grassland (steppe) biome similar and different? Consider the vegetation characteristics, climate (temperature and precipitation), and location of these two biomes. For each of these three categories, provide at least one similarity and one difference. (3 points) vegetation characteristics both have vegetation that is adapted to regrow after fire shrubs (more woody plants) in chaparral, grasses and non-woody (herbaceous) plants in steppe chaparral plants are grown for food, and grains are grown for food in the grassland biome (I could envision this type of response phrased as a similarity, or a difference if the students specify the kinds of plants, e.g., olives and citrus versus wheat) climate chaparral has dry summer and wet winter, grasslands experience drought, but not only in the summer both biomes experience drought at some time climate of chaparral is moderated by the ocean; steppe climate is more variable throughout the year location chaparral is on west coast of continents; grasslands often are in interior of continents neither biome is on the equator; both are in the middle latitudes students might give specific locations such as the Mediterranean Basin or California and the central United States or the interior of the European and Asian continents; accept this type of answer, if the locations are correct 17. Consider the ways we can graphically represent geographic patterns of plants. Provide four reasons why two different maps of the vegetation of Minnesota could look very different. You may use the example of the Kchler map and the Marschner map (shown and discussed in class) to illustrate your answer. (2 points) Possible answers include Different scales Different levels of generalization Different data sources Different resolutions of data Different map makers Different time periods represented on the map Different assumptions about the role that climate plays in determining vegetation Geog 1403Spring 2010Exam 1cpage 4
