Prerequisite: BIOL 214
This course focuses on the morphologic and taxonomic diversity of mammals in phylogenetic and ecologic contexts. By the end of the course, students will be able to: (1) describe the key anatomical features of mammals; (2) identify the main anatomical characteristics of all orders and most families of living mammals and their functional importance; (3) perform a basic phylogenetic analysis using morphological data; (4) appreciate major modern and historical patterns in mammal diversity and biogeography. Two lectures and one lab each week; most labs take place at the Cleveland Museum of Natural History. This course satisfies a laboratory requirement for the Biology major. Prerequisite: BIOL 214.

• M: MacDonald, D.W. 2009. The Princeton Encyclopedia of Mammals. Princeton University Press.

Other Required Reading (see syllabus):

• Wiley, E.O., D. Siegel-Causey, D.R. Brooks, and V.A. Funk. 1991. The Compleat Cladist; a Primer of Phylogenetic Procedures. University of Kansas Museum of Natural History Special Publication No. 19. Available on Blackboard.

Videos:

The Life of Mammals (DVD) 2003. Hosted by David Attenborough.  Four volumes, 10 parts in total. BBC.
Available via KSL Course Reserves.

Structure:

Lectures: Lectures will consist of a general overview of one or more mammal groups, including taxonomic and morphologic diversity, ecology, evolutionary history, and phylogenetic relationships. Lectures will also include comparative discussions of some key mammal adaptations (e.g., reproduction, echolocation, etc.). Students are expected to complete assigned readings and watch any assigned video segments prior to each week’s lecture (except for the first lecture of the course).

Labs: Osteology labs (O) will focus on osteology of extant mammal groups and will be held at the Cleveland Museum of Natural History. These labs will use specimens from the research collections of the CMNH. To prevent damage to these specimens, no touching will be permitted. You should feel free to bring a camera to take photographs of specimens for future reference. However, a photographic guide to mammal skulls has been developed for use with this course and will also be available. Phylogenetics labs (P) will focus on understanding modern phylogenetic techniques and will be computer-based, taking place in Clapp 304. NOTE: You should download Phylip (a free program) for the first phylogenetics lab.


Student Assessment:

Quizzes (50% of final grade): Most labs will begin with a short quiz (10-15 points, short answer and/or multiple-choice questions) covering the previous week’s lectures, readings associated with those lectures, and videos. Details of the schedule and content are noted on the syllabus. Each student’s two lowest quiz scores will be dropped from the final grade.

Lab Reports (20% of final grade): The two phylogenetics labs and the zoo lab will each have an associated lab report. Some activities will be completed during lab, others will require additional out-of-class time. Lab reports from phylogenetics labs will be due at the beginning of the Thursday lecture of the following week. The zoo lab can be completed at any time during the semester, but must be submitted no later than November 22. They will be weighted equally in terms of grading.

Final Exam (30% of final grade): A combined lecture and lab exam will take place at the CMNH during finals week (see syllabus). It will have three components: (1) identification of osteological specimens (mainly skulls) to order and family; (2) identification of photos of living mammals to family, plus associated short answer questions (e.g., size, diet, habitat, geographic range, order, etc., of that particular animal); and (3) written exam, mostly short answer questions (e.g., definitions, compare/contrast), basic phylogenetic methods, and some multiple choice questions.

Additional Requirements for Graduate Students (enrolled in ANAT/BIOL 445):

Graduate students will have additional readings from an edited volume on the evolution of placental orders and selected journal articles. Content from these additional readings will be included in the weekly quizzes. The schedule is as follows:

Dec. 7
In the above schedule, R&A = Rose, K.D., and J.D. Archibald. 2005. The Rise of Placental Mammals. 2nd edition. The John Hopkins University Press, Baltimore, 259 pp. Other readings refer to journal articles. PDFs of all readings are available on Blackboard.

Graduate students will also be required to do a research report on an extinct group of mammals. The group must be approved by the instructor by October 1st (sooner is better). The research report will be in the form of a review article for the Journal of Vertebrate Paleontology. Detailed guidelines for manuscript preparation are available here and on Blackboard.

Minimally, the manuscript must:
•    have a body of at least 17 pp. (not including title page, abstract, references, etc.)
•    cite at least 30 references from the primary literature
•    incorporate five figures, including a phylogeny

The final paper will constitute 15% of the student’s final grade, with the other three components weighted as follows: quizzes = 40%, lab reports = 15%, and final exam = 30%.


How to succeed in this course:

•    Do the assigned readings and scan the relevant handouts before class. This will facilitate learning by making you familiar with the groups and names to be discussed.

•    Learn the names and proper spellings of the groups we discuss in class. Taxonomy is how the great diversity of mammals is organized. You cannot learn about mammals without learning names of groups. Make flash cards if you think that will be helpful, or download a flash card app for your smart phone.

•    Learn or review typical mammal osteology. We will have a lab on this early in the course, but one session will not be enough time for you to internalize and recognize all of the relevant structures. Sketching bones is a good strategy for learning anatomy.

•    Appreciate the detailed structure of teeth. Few aspects of a mammal’s anatomy are as important as its teeth. They provide information about ancestry (evolutionary relationships) as well as ecology (diet). Learn how to recognize different types of teeth and how to describe them. As for bones, sketching teeth is an effective strategy.

•    For information on mammals, bear in mind that sources vary, and that the field is constantly changing. In general, more recent references will be more accurate. When in doubt, ask someone or refer to the lecture notes.

•    What do you need to know for each group? Generally speaking: Taxonomy and Phylogeny: What is the group name? Where does the group fall in the taxonomic hierarchy? How is it related to other groups? Biogeography: Where do these animals live on the globe? Ecology: What do these animals eat? How big are they? How do they move and where do they spend their time? In what types of habitats do they live? Identification: How can you recognize a member of this group? Fossil record: What do fossils tell us about the evolution of the group, including the topics noted above?

•    In general, you should focus on topics mentioned in class. Lectures and labs may not cover everything you need to know, but they will cover the vast majority of material.
