YeunShin Lee & Cassandra Tucker 2021 ANS 104 Principles and Applications of Domestic Animal Behavior Take-home Exam 3 Prompt 2021 DUE: TUESDAY, November 9 at 11:59 pm PST Please note: Although we are happy to answer questions related to course content and welcome as many of you to our office hours as possible, the teaching team (e.g., Dr. Lee, Ashlynn, and Patrick) will NOT answer any questions specific to the questions asked in this exam. If you do not understand a question, you can ask for clarification by writing an email to Dr. Lee or by explaining your confusion when you submit your completed exam. Your explanation will not count toward your page limit and will be considered when grading your exam. We are using this approach to standardize the information being given out about the exams across the entire class. Instructions: READ CAREFULLY 1. Compose responses to the questions below about an imaginary creature, called a floof, and upload your completed take-home exam to Canvas by the due date. Only uploaded exams will be graded. Please upload your document as either a .pdf or a format that is Word compatible. Canvas does not accept documents in .pages format. Should you encounter difficulties uploading your submission, contact Dr. Lee ASAP. 2. In order to answer the questions to this take-home exam, you will need to refer to your notes and assigned readings for the lecture and discussion topics Foraging, Motivation, and Stereotypic behavior. Although the background is based on imaginary creatures, your responses should be grounded on the actual, real-world concepts presented to you in lecture, your text, and discussion. This work is to be completed independently by each student. No citations are needed, as we are evaluating your understanding of concepts. 3. Do NOT WAIT until the last minute to upload your essay. Canvas will automatically treat your essay as late beginning at midnight and automatically apply a 24-hour late penalty. Late assignments will lose 25% of the assignments value per 24-hours for every day they are late. Once we have returned graded exams, late submissions will no longer be accepted. Having submission trouble when you are uploading your exam at the last minute will not excuse you from the late penalty. 4. Your response should be composed using correct grammar, complete sentences, and appropriate paragraph structure (e.g., discrete idea/question addressed by distinct paragraphs). 5. Formatting criteria: ? Responses should be typed in Times Roman, Calibri, or Corbel 12-point font. ? Responses should be double-spaced ? Responses should have Normal margin settings ? Minimum exam length, excluding heading information: page + filled-in Duncan-Hughes model ? Maximum exam length, excluding heading information: 1.5 pages + filled-in Duncan-Hughes model YeunShin Lee & Cassandra Tucker 2021 Background: All floofs and blimps in ANS 104 exams are entirely imaginary. Floofs are ambush predators that hunt blimp, a large wild ungulate. A single blimp is large enough to feed a floof for several days, so wild floofs only hunt 1-2 days after they have completely consumed their previous kill; when they are really hungry. A floof hunting in the wild will leave its den in search of blimp. The hunting floof looks for trails that have been trodden down by a passing blimp herd. Once a floof has located a blimp trail, it will follow the trail, sniffing the ground for blimp scat. Once it finds a pile of blimp scat, the floof will leave the trail and seek out a concealed spot next to the trail near the scat pile from which the floof can hide and wait. Because blimp typically use the same trail for several days, a pile of scat indicates that there is a good chance that the blimp herd will pass that way again. If blimp do not pass by the floofs concealed spot within an hour, or so, the floof will abandon that spot, and look for a new blimp trail. If, on the other hand the blimp herd do return on that trail, as soon as a blimp is close enough, the floof will launch itself from its concealed spot directly at the blimp and will use its jaws to attempt to grab the blimp by the throat. If the floof succeeds at grabbing the blimp by its throat, the floof will use its jaws to clamp down on the trachea of the blimp and suffocate it. As soon as the blimp dies, the floof will drag the blimp back to the floofs den. At the den, the floof will eat the blimp using its teeth to tear off chunks of muscle that the floof swallow whole. As soon as the floof is no longer hungry, it will hide the remainder of the blimp carcass by digging a shallow hole near its den, placing the blimp carcass in the hole, and then covering it with rocks that it carries to the hole in its mouth; a behavior known as caching. As long as there are blimp carcass remains in its cache, the floof will not hunt. On ranches, floofs are fed once daily. Although ranchers are careful to provide the floofs with sufficient nutrition, whenever the ranchers have surplus meat, they would feed all of it to the floofs, knowing that floofs will still eat meat that is a few days old. On ranches where feeding surplus meat was a common practice, some of the floofs would carry leftover meat to corners where they would dig in the concrete floors of their enclosures. The floofs that would dig in the corners of their enclosures would dig for hours, often sustaining injuries to their paws. Questions: The following questions draw upon the lectures, reading and discussion material focused on foraging, motivation, and stereotypic behavior. When answering the questions, unless you are instructed otherwise, rely only on the facts provided to you in the background. 1. For wild floof foraging behavior, fill in the blank Duncan-Hughes model. Make sure to include all the behaviors provided to you in the background that are appropriate for each box in the Duncan- Hughes model. 2. The following questions are about the floofs digging behavior. a. From the background, how many ways can you find that would identify floof digging as an abnormal behavior? What are they? b. What kind of abnormal behavior is floof digging? How do you know? 3. One of the ranchers whose floofs were digging in their enclosures decided to conduct an experiment to understand why their floofs were performing so much digging. This rancher divided their floofs into enclosures in two separate barns. In one barn, the floofs were fed only the quantity of meat YeunShin Lee & Cassandra Tucker 2021 that they could completely consume in one day. For this barn, toward the end of the day, the rancher also checks to make sure that no meat remained anywhere within the enclosure. If there was some leftover meat, the rancher removed it. In the other barn, the floofs were fed surplus meat. The rancher then compared the amount of digging performed by the floofs in each barn and learned that floofs from the barn that received surplus meat performed more digging behavior than the floofs that from the barn with no leftover meat. a. Which of the 3 causes of stereotypic behavior (e.g., sustained elicitation, reinforcement, or CNS dysfunction) do the findings of the rancher support? How do you know? [HINT: In order to answer this question, you may find it helpful to fill in a D-H model for yourself for why floofs dig.] b. What intervention could the ranchers use to stop the digging behavior?
