BSCI 106 Fall 2009 Dr. Sara Via Study Questions Set #1 (Lectures 1-5) Due by 9/14 Instructions: These questions are meant to help you know whether you grasp the important topics in this set of lectures. It will really help you to go through all of the questions and at least outline the answer. If you know everything in these questions, you will be in very good shape for exams (though I won’t guarantee that these are the only things I’ll ask on a test). You are required to choose any two questions of these questions and answer each one in about 3-5 complete sentences. Grading will be on a scale of 0, 3 or 5 for each question, as follows: 0: You don’t turn it in or your answer is extremely sketchy or dead wrong. 3: You make a pretty good effort and get at least some parts right. 5: Your answer is clear and mostly correct (but NOT too long) Your TA will grade these quite quickly, and you can be sure that the grades are applied equivalently and fairly across the class. IF some TAs grade harder than others, we can adjust for it at the end. You should realize that receiving a 5 DOESN’T you’re your answer is perfect—you should always check the posted answers to be sure you got it all. No regrades—this is only a few points! Behavioral Ecology 1. What are three functions of communication? Describe an example of one type of communication used for each function. Try to include examples of visual, sound and chemical communication. Note: these are not the only correct answers. a. Find a mate- frog calling (sound), moth pheromone (chemical), mating dance (visual) b. Find food- bee dance (visual), ant trails (chemical) c. Communicate danger -- alarm call (sound), alarm pheromone (chemical) d. Display of anger or threat behavior - dog and cat posture (visual), growling (sound) lizard dewlap extension and pushups (visual) 2. What is the difference between active and passive visual communication? Active visual communication involves some movement or behavior, such as a dance or a threat display (posture, etc), while passive visual communication is achieved primarily through colors (white breast of the male sage grouse, other male coloration in birds, or bright colored dewlap of lizards) 3. Why is sound communication more likely to attract predators than visual communication? Sound communication is effective over larger distances, at night and can be detected by organisms that are not looking directly at the communicator.

BSCI 106 Fall 2009 Dr. Sara Via 4. What is innate behavior? Describe the function of the releaser, and give at least one example. Innate behaviors are determined primarily genetically, and are not modified by experience. The releaser is a stimulus (visual or otherwise) that triggers the initiation of the innate behavior. Once the behavior is triggered, it will go to completion. 5.
