STUDY QUESTIONS – SET 3 Here is an example of a question we used on a previous year’s exam, which dealt with European Eel Migration. As you can see, this question provides you with a little background, and then asks you to come up with both a hypothesis and a realistic experiment that you could perform to test your hypothesis. I HAVE UNDERLINED KEY PHRASES. Students had the question in advance, and could learn about eels on their own prior to the exam. If you practice writing out this question, it will be very helpful to you for doing well in this course. HYPOTHESIS QUIESTION: European eels perform dramatic migrations as part of their life history. These fish are spawned at great depths in the Sargasso Sea in the middle of the Atlantic Ocean. From there they migrate to river systems in Europe where they live for several years before returning to a particular location in the Sargasso Sea to spawn and die. The mechanisms underlying this amazing behavior are not well understood even today. As a recent graduate of UC Davis, you have been hired by ICE (the International Commission on Eels) to examine whether learning plays a role in this migratory behavior. Upon arriving at ICE headquarters you learn that 1) staff researchers have finally developed techniques for obtaining and rearing baby eels in the lab, and 2) Sargassum weeds produce scented compounds that may be distinctive to the Sargasso Sea. Based on this information, use Tinbergen’s SECOND question to propose a testable hypothesis to explore this problem further. BELOW ARE THREE DIFFERENT ANSWERS: SAMPLE ANSWER ONE: HYPOTHESIS (hint: to receive credit, keep it simple and grammatically correct): Eels imprint to odors during the larval stage of development. How would you test your hypothesis? (remember to use the format in the study guide). Test: To test whether the larval (‘leptocep halous’) stage imprint to scents, I will use two groups of eels sampled from a single population to control for possible genetic differences in this behavi or. Eels will be reared under controlled lab conditions, which will allow eels to transition from salt water to freshwater, and then back to saltwater as mature adults (‘silver’ eels). I will expose one group of eels to an odor that I have previously determined that they can detect (for
