1 TROPICAL ECOLOGY, EEB 151A FINAL Fall 2005 Prof. Arthur C. Gibson INSTRUCTIONS: PRINT your name clearly on the Answer Sheet and your student ID number. PRINT the answer perfectly clear as a capital letter. Be sure that the question number corresponds to the number on the Answer Sheet. If you do not understand a question, ask now, but please do not ask for definition or explanation of a technical term. Be sure to answer all questions, because there is no penalty for guessing. Turn in the Answer Sheet; keep the exam questions. The answer key for the exam will be posted on the course website probably this evening if there is no problem getting online, and, if not, tomorrow morning. The scores and later course grades will be posted on myUCLA as soon as they can be calculated and entered. Please remember that all courses on campus are using myUCLA now, and there may be massive delays during Finals Week. MULTIPLE CHOICE. Items 1 70 on the Answer Sheet. 2.9 points each.
