Exam 2 Key A. Several notable features of the 2011 growing season: Cool and late spring, marking a late beginning to the growing season; abundant early season moisture, including sometimes excessive moisture and flooding in some areas; warm, suitable temperatures through much of the summer; later summer and early autumn dry conditions; unusually early frost (September 15) resulting in a shorter than average growing season. B. Tradeoffs involve a combination of benefits and limitations associated with a trait. For example, a plant might produce few, large, well-endowed seeds or numerous small seeds. The former have a larger energy resource content but might not be as readily dispersed as small seeds that can reach many different habitats, but, once there, those seedlings have less resource reserve for initial growth. Numerous other examples could be cited.

Unformatted text preview: C. Dispersion patterns: a. Clumping might be due to limited seed dispersal, vegetative propagation, growth restricted to localized, favorable microhabitats, or interactions with other species. b. Random dispersion might result from widespread dispersal of numerous seeds, such as by winds that are variable in direction and speed. Regular dispersion might be due to competitive interactions, shoot emergence at regular intervals long rhizomes, or human planting efforts. 1. B 2. D 3. C 4. E 5. A 6. C 7. E 8. D 9. B 10. A 11.
