The aim of this course is to let students know the concurrent progress in the research of the ecology of Artiodactyla, find questions that need to be answered by reviewing literature, and suggest future research works. In the first half of this course, the instructor will lead a review on the important literatures of Artiodactyla behavior. In the second half of this course, each student will choose a topic on the behavior of Artiodactyla, review research papers on the topic, and periodically present the progress orally. At the end of the semester, each student has to turn in a written report of the paper review.
