Courses in Biology (DIVISION 328)

100. Biology for Nonscientists. Not open to those with Advanced Placement or "Departmental" credit in biology, nor to those concentrating in the biological sciences. (4). (NS).

Biology 100 is a one term course designed to introduce students to current biological concepts. The course consists of three hours of lecture per week plus a coordinated discussion session which occupies two hours per week. Biology 100 provides an introduction to some general principles of biology and concentrates on the areas of cell biology, genetics, evolution, and environmental biology. A major objective of this course is to point out to students the nature of the scientific process and illustrate the uses and non-uses of science in contemporary life. Wherever possible, the ethical and social implications of contemporary scientific effort will be discussed.

This course is designed for students with a minimal background in the biological sciences but we do assume some exposure to biology at the high school level. Discussion sections enroll 20 students and are taught by graduate student teaching assistants. In the discussion section, students have the opportunity to review material presented in lecture and participate in discussions of issues raised in the lecture segment. Cost:3 WL:1; you MUST attend the first discussion section to claim your place in the course.

101. Biology and Human Affairs. (4). (NS).

This course is an introduction to those aspects of biology that have direct applicability to the lives of people in today's world. It covers current controversies within biology, especially as they relate to human life and human affairs. Topics discussed include IQ and genetics, sex roles, agriculture, world hunger, and the environment. Background information is given for each topic, but the emphasis is placed on the controversies and the role of science in human affairs. In addition to the two lectures per week, there is a two-hour discussion period in which the topics are further explored and films are frequently shown. Cost:3 WL:2 (Vandermeer)

102. Practical Botany. (4). (NS).

Practical Botany is an introductory course in learning how to grow and use plants. Students will learn how to grow, identify, propagate, and take care of many different useful plants both common and exotic ones. The major topics in lecture and laboratory include wine, mead, and beer making; plant propagation by cuttings, and other vegetative means (runners, bulbs, corms, offsets, divisions, and underground stems); breaking seed dormancy, and seed germination; forcing spring corms and bulbs into flower indoors; edible wild plants; natural plant dyes and dyeing wool; fall vegetable gardening, organic gardening and composting; alternative means of pest control; plant pruning, including bonsai; landscaping around the home; how to make hanging baskets and terrariums; drying and use of plants for crafts; flower and fruit types and structure as related to pollination and plant breeding; construction of solar greenhouses and coldframes; herbs and their uses. Hands-on work by the students is a major part of this course. There are several field trips which emphasize ecology, edible wild plants, and poisonous and medicinal plants, as well as visits to Peter and Hazel Kaufman's farm at Dexter, MI, and Willow Run Farms at Belleville, MI, where herbs are grown hydroponically in greenhouses heated with methane obtained from the Wayne county garbage dump as "bio-gas." Two of the highlights of the course are a trip to Brighton Bog and a natural foods and edible wild plants dinner which the students prepare. There are two lectures and one four-hour discussion/lab period per week. The labs are held at the Botanical Gardens (free bus transportation is provided). Required book is PRACTICAL BOTANY by Peter Kaufman et al, available as a course pack (book now out-of-print). [Cost:2] [WL:3 (at 4103B Nat Sci) (Kaufman)

The theory of Evolution is the basis for understanding the origin of species and biological processes. Biology 155 is a reading/discussion course centered on the main elements of "Evolutionary Thinking." This course begins with selected works of Charles Darwin and then considers several unsolved problems in evolution such the origin of life, rates of evolution, the nature and frequency of extinction and the units of selection. The second half of the course is concerned with the evolution of man, and the possible contribution of Evolutionary Thinking to understanding the origin and structure of aspects of human culture. Weekly reading assignments provide the basis for discussion. One term paper is required. Open only to students admitted to the LS&A Honors program. To accompany Biology 154. Cost:1 WL:4

305. Genetics. Biol. 152 or 195 (or the equivalent). (4). (Excl).

This course is designed for students who are concentrating in the natural sciences, or who intend to apply for graduate or professional study in basic or applied biological sciences. This introduction to genetics is divided into three segments: nature and properties of genetic material, transmission of genetic material, and function and regulation of genetic material. There are three hours of lecture a week and one discussion section directed by teaching assistants. The discussion sections are used to introduce relevant new material, to expand on and review the lecture material, and to discuss problem assignments. Grading is based on examinations covering the lecture material, discussion material, reading assignments in the text, and problem sets covered in the discussion sections. [Cost:2] [WL:1] (Pichersky and Rizki)

CSP section(s) available. See the Comprehensive Studies Program (CSP) in this Guide.

306. Introductory Genetics Laboratory. Prior or concurrent enrollment in Biol. 305. (2). (Excl).Meets a Biology laboratory requirement.

This course provides students with laboratory experience on basic genetic principles. Students should have already taken or be concurrently taking the 305 Genetics lecture course. The first half of the course is devoted to genetic analysis in Drosophila by a series of crosses and in Sordaria (a fungus) by ordered tetrad analysis. Students will analyse the linkage relationship and mapping of unknown mutants of Drosophila. The experiments in microbial genetics during the second half of the course include mapping by conjugation in E. coli, transduction experiments using bacteria and phage, and complementation experiments for studying gene as a unit of function using different "his" mutants of yeast. One three hour lab is scheduled each week additional three hours of lab time per week is expected at irregular times. Students are expected to write four lab reports and to keep a complete and accurate record of all results and analyses in a bound lab notebook. There are 2 quizzes given during the term. [Cost:1] [WL:2] (Jeyabalan)

341. Parasitology. Biol. 152-154 or 195 (or the equivalent). (4). (Excl).Meets a Biology laboratory requirement.

This course concentrates on the biology of animal/animal interactions including parasitism, commensalism and mutualism. The focus is primarily evolutionary and ecological, with emphasis on the origins and development of such associations. The organismal approach will be stressed in studies of Protozoa, various helminth groups and arthropods, with examples including parasites of medical and veterinary importance. Discussions of host-parasite interactions will include co-evolutionary perspectives as well as traditional approaches. No specific background other than introductory biology is required, although courses in ecology and evolutionary biology will be helpful. Students will be evaluated on the basis of two hour exams, a lecture final, laboratory quizzes and a practical examination. This course consists of three lectures and one laboratory weekly. Cost:3 WL:3 (OConnor)

351. Vertebrate Biology and Structure. Biol. 152-154 or 195; or the equivalent. (6). (Excl).Meets a Biology laboratory requirement.

The course has multiple aims. The dissection in the laboratory introduces the student to the structural pattern, mainly of shark and cat, but also of a series of other vertebrates. It is intended to lead to a comparative understanding of the roles and evolution of structures in the major functional systems of protochordates and vertebrates. Lectures are designed to put these structural observations into a broad perspective by focusing on the function, origin, and evolution of chordate structures, with particular emphasis on those of vertebrates. The laboratory also includes demonstrations, film presentations, and a visit to the Natural History Museum. Cost:3-4 WL:1; all students will be admitted. (Gans)

355/Nat. Res. 337. Woody Plants I: Biology and Identification. Biology 152 or 195 or equivalent. (4). (Excl).Meets a Biology laboratory requirement.

The identification of trees, shrubs, and vines is the basis for the study of their biology and ecology. Identification and ecological relations are taught during one afternoon field trip per week. The plants are studied in their natural habitats and communities dry oak-hickory forests, mesic-maple forests, river floodplains, swamps, and bogs. Non-native species and ornamental plants are taught in Nichols Arboretum, Main Campus, and Saginaw Forest. An introduction to the biology and ecology of woody plants is given in lectures. Topics include vegetative and reproductive morphology, life histories, forest ecology, physiological ecology, genetics and variation, systematics, conifers, and winter identification. Also discussed are important trees of southern and western U.S., China, and the Tropics. Field trips are scheduled from 1:00 to 6:00 once a week. MICHIGAN TREES (Barnes and Wagner) is the required textbook. Lecture material is based in part on the book, FOREST ECOLOGY (Spurr and Barnes).

(Barnes and Wagner)

381. General Ecology. Biol. 152-154 or 195 (or the equivalent); and a laboratory course in chemistry. (5). (Excl).Meets a Biology laboratory requirement.

This course introduces the basic concepts and principles of ecology as applied to the study of individuals, populations and communities of both plants and animals. Course topics include the role of physical and biotic factors influencing the distribution and abundance of organisms, dynamics of single species populations, competitive, predator-prey, and mutualistic interactions, community organization, ecological succession, evolutionary aspects of ecology, and current applications of ecology to problems of environment and resource management. Biology 381 is a suitable prerequisite for intermediate and advanced courses in ecology. There are three lectures a week and one discussion period. The laboratory meets one day a week for four hours at the Matthaei Botanical Gardens, 1800 Dixboro Road. Field trips to outlying study areas are included. Free bus transportation between the Main Campus and the Botanical Gardens is provided. An independent project, several laboratory reports and two one-hour exams, plus a final examination, constitute the main basis of evaluation. [Cost:3] [WL:2] (Rathcke)

411. Introductory Biochemistry. Biol. 152 or 195 (or the equivalent); and Math. 113 or 115; and organic chemistry and physics. No credit granted to those who have completed or are enrolled in Biol. Chem. 415. (4). (Excl).

The major objective of this course is to provide upper level undergraduates and beginning graduate students in biology, physiology, cellular and molecular biology, pharmacy, biological chemistry, chemistry, pharmacology, toxicology, nutrition, physical education, microbiology, bioengineering, and other related areas of biology with an appreciation of the molecular aspects basic to metabolism in living cells. As an introductory course, emphasis is placed on a broad view rather than a detailed knowledge of this enormously encompassing field. Thus, biochemistry is defined in the broad sense, i.e., that organizational level of biology as described in molecular or chemical terms and reactions; the chemical basis of life. This course is directed toward those contemplating a career in some aspect of experimental biology including medicine, dentistry, and other professional pursuits. The general subject matter includes amino acids, protein structure and function, allosterism, molecular disease, enzyme properties, kinetics and mechanisms, connective tissue proteins, membrane structure and function, energetics, intermediary metabolism and its regulation, biosynthetic processes, DNA, RNA, transcription, the genetic code and protein synthesis, control of gene expression, free radical and antioxidant biochemistry, hormone action and metabolic control.

This course is taught by a self-paced, personalized system of instruction. Students interact, according to their own schedules, with undergraduate TA's chosen according to interest and ability to help other undergraduates with biochemistry. The course is divided into 15 logical units of material, and students are required to MASTER the content of each unit. Upon attaining mastery, the student may take both a written and an oral quiz which, upon completion, is graded and evaluated by the TA. If mastery is attained, the student may proceed to the next unit. Grades are assigned according to the number of units successfully completed plus a factor derived from performance on the midterm and final examinations. This system is designed to take into consideration different rates of individual learning as well as to eliminate competition among students. TA's are available approximately 60 hours/week in a suite permanently assigned to this course. Several lectures dealing with biochemical topics are presented by Professor Beyer. Material covered in these lectures represents an extension of information in the course, i.e., not in the textbook, and is not the subject of examination. Students are encouraged to attend sessions in which biochemical discoveries are presented by TA's and the professor. [Cost:3] [WL:3, course is never allowed to close. (Beyer)

412. Teaching Biochemistry by the Keller Plan. Biol. 411 and permission of instructor. May not be included in any of the Biological Sciences concentration programs. (3). (Excl).This is a graded course. (EXPERIENTIAL).

Biology 412 adheres to the old Chinese proverb: "I hear and I forget. I see and I remember. I do and I understand." Undergraduates who previously have taken an introductory biochemistry course act as proctors (tutors, TA's) for students currently taking Introductory Biochemistry (Biology 411). Six hours per week (twelve hours in the Spring half-term) are spent helping and quizzing Biology 411 students. In addition, each proctor provides two mastery level, multi-choice questions for each course unit (30 total) from which the instructor constructs the final examination and midterm examination for both Biology 411 and 412. Proctors also prepare a report on a biochemical discovery which they present to their peers, the 411 students, and the instructor. The major roles of the proctors are to examine the students on their mastery of unit material and to help the student requiring explanation supplementary to the textbook. At the completion of an instructor-generated written quiz, the student and proctor grade the quiz together. The proctor asks the student additional verbal questions generated by the proctor. The proctor passes a student when, and if, the proctor feels the student has MASTERED the unit material. Student-proctor interactions are evaluated by the students. The proctors are graded on the basis of the quality of their final and midterm examination questions, their biochemical discovery session presentations, and their grades on the midterm and final examination. Proctors learn considerable biochemistry by repeated teachings of unit materials and, in addition, profit from their experience as teachers and evaluators. [Cost:1] [WL:3] (Beyer)

418. Endocrinology. Biol. 152-154 or 195; a course in physiology (cellular, general or comparative); organic chemistry. (3). (Excl).

This course is a comparative study of animal endocrine functions with emphasis on the evolution of hormones and of hormonal control, the cellular origin and chemical nature of hormones, their physiological actions in organisms and the biochemical mechanisms of hormone action. The course will concentrate on the endocrine systems of vertebrates. One-fifth of the course is devoted to a detailed description of Reproductive Endocrinology. Individuals interested in the human or clinical aspects of hormones would be better served by any of several courses offered by various units of the Medical School. Instruction in Biology 418 assumes a basic familiarity with General and Comparative Physiology. Training in chemistry through organic is essential and a course in biochemistry would be helpful. Evaluation is based on two midterms and a final exam. [Cost:3] [WL:1] (Doneen)

419. Endocrinology Laboratory. Prior or concurrent enrollment in Biol. 418. (2). (Excl).Meets a Biology laboratory requirement.

This laboratory course should be taken concurrently with the companion lecture course, Biology 418. Enrollment is limited to 16 students. Lab work will emphasize modern techniques in the identification, isolation and mechanisms of action of hormones. One-third of the course is devoted to the "Independent Project," an original experiment designed, conducted and written by each student. The Independent Project forms the one major writing assignment. The course grade is also determined by weekly problem sets based on interpretation of lab data, and a final exam. Two three-hour lab periods are scheduled; the nature of biological systems, however, makes it advisable to anticipate an additional two or three hours of lab time at various (and occasionally odd) times in the week. Students should be aware that this lab uses live animals (predominantly mice and chicks), and three radioactive isotopes, 14-C, 3-H and 125-I. Cost:2 WL:1 (Doneen)

422./Anatomy 422. Cellular and Molecular Neurobiology. Biol. 152-154 or 195 (or the equivalent), one year of physics, prior or concurrent enrollment in biochemistry. (3). (Excl).

This course deals primarily with the properties of individual nerve cells, and small groups of nerve cells. This provides the basis for understanding the processing of information by the nervous system, the mechanisms underlying learning and memory, and the biological basis of neurological and psychiatric disorders. Topics to be covered include the cell biology of neurons and glia, the generation of electrical potentials, the transmission of information between cells, and the cellular basis of simple forms of learning. Considerable emphasis will be placed on understanding the molecules that endow the nervous system with these properties. In combination with Biology 425 this course represents a comprehensive introduction to neuroscience. Cost:2 WL:2 (Hume and Bodmer)

427. Molecular Biology. Biology 305 and Biology 411 or Biol. Chem. 415, or equivalents. (4). (Excl).

Emphasizes understanding methods and interpretation of data. Topics include DNA replication and transposition, chromosome incompatibility and segregation, transcription and translation, the processing of macromolecules, signal transfer, and regulation at various levels. Three lectures per week are supplemented by a 1.5 hour discussion section. There will be two examinations during the term, quizzes and a final. Cost:4 WL:2 (Helling)

437. Biology of Invertebrates. Biol. 152-154 or 195 (or the equivalent), or introductory geology and two additional natural science courses. (5). (Excl).Meets a Biology laboratory requirement.

Animal diversity is reviewed with emphasis on all but vertebrate animals, which together account for only part of one of some 40 animal phyla. Current evidence for the evolutionary relationships within and between groups is presented, and this phylogenetic perspectives is emphasized as an important aspect of understanding animal architecture, patterns of development, and adaptations to the environment. The basic life functions that all animals share are also emphasized, with examples of alternative solutions to the same requirements chosen from even closely-related animal groups. The course consists of lectures, laboratories, and some local field trips. Laboratory study emphasizes mostly living material as supported by preserved animal special preparations. Evaluation is by written and practical laboratory examination. Cost:3 WL:4 (Eernisse)

442. Biology of Insects. Any college-level biology course. (4 in Ann Arbor; 5 at Biol. Station). (Excl).Meets a Biology laboratory requirement.

This is a general course which covers information concerning four-fifths of the Animal Kingdom and is intended to give some perspective on invertebrate systems as opposed to the more usual attention to vertebrate animals. The emphasis is on the whole animal what it is, what it does, how it does it, how it got there. In lectures, a wealth of information and generalizations gathered from insects concerning all major aspects of biology is discussed. In the laboratory, observation and description of behavior of living insects, natural history and ecology, collection and observation of living insects in their natural habitats, brief reviews of morphology and anatomy, and recognition of orders and families are emphasized.

This course is an introduction to specialization in all aspects of biology in which insects are appropriate experimental organisms, and an introduction to the appreciation and enjoyment of living animals. The following topics are discussed in lecture, with special emphasis on aspects recently treated in research publications: synopsis of orders; general functional anatomy and morphology; regulation of activity and nervous organization; regulation of development and molting; ovarian and egg structure; embryology; digestion, nutrition, excretion, and respiration in insects; genetics, sex determination, mimicry, and insecticide resistance; social organization in insects; zoogeography, geographic variation, and species; geological history and evolutionary relationships of insects; insect flight. The laboratory work encompasses a more unified scope.

The only prerequisites for this course are an introductory college course in biology or zoology and an interest in understanding living organisms. There are two one-hour lecture periods and two three-hour laboratory periods per week, plus several optional Saturday morning field trips. Only one text Borror, Triplehorn and Johnson's AN INTRODUCTION TO THE STUDY OF INSECTS (sixth edition) - is required for both lecture and laboratory. EXCEPT FOR PREPARING AN INSECT COLLECTION AND SOME COLLECTING, OUTSIDE WORK IS AT A MINIMUM. There is at least one essay hour exam, and a final essay exam in lecture, which are comprehensive in nature, and a minimum of four one-hour practical examinations in laboratory. Cost:3 WL:1 (Moore)

451. Biology of Mammals. Permission of instructor. (4). (Excl).Meets a Biology laboratory requirement.

The course introduces students to the evolution, ecology, behavior and structure of mammals. We will study the evolutionary history of mammals; examine adaptations for running, digging, swimming, and flying; and learn about current research in the ecology, behavior, zoogeography and systematics of mammals. The two lectures each week focus on various aspects of the biology of mammals. In laboratory sessions (two three-hour periods each week), students will survey the orders and families of mammals of the world, as well as learn about the species of mammals in Michigan. Occasional weekend field trips will provide an opportunity to learn about local faunas, and in addition, something about how wild mammals are studied in the field. A text supplements the lectures, and a published manual is required for the laboratory. There will be two hour exams (covering lectures and assigned reading) and several lab exams, including a final. Cost:2 WL:1 (Myers)

483. Limnology: Freshwater Ecology. Advanced undergraduate or graduate standing, with background in physics, chemistry, biology, or water-related sciences. (3). (Excl).

Limnology is the study of lakes. Some of the topics covered in this course are: the origin of lakes; the importance of physical and chemical properties; the geochemical cycling of carbon, phosphorus, nitrogen, iron, and silicon; the ecology of aquatic bacteria, phytoplankton, zooplankton, benthos, macrophytes and fish; the pollution and eutrophication of lakes; paleolimnology; food-chain dynamics; energy-flow; and experimental investigations using whole lakes. Lectures are designed to provide the student with a basic understanding of limnology in addition to presenting up to date information from the current literature. Grades are based on examinations (no term paper). Wetzel's LIMNOLOGY, second edition, is the text. This course fulfills concentration requirements in the area of Ecology and Evolution. The limnology laboratory is offered as a separate course Biology 484 described below. [Cost:2] [WL:1] (Lehman)

484. Limnology Laboratory. Prior or concurrent enrollment in Biol. 483 and permission of instructor. (3). (Excl).Meets a Biology laboratory requirement.

The limnology laboratory is open to 12-15 students by permission of the instructor. Several field trips to local lakes will enable students to master sampling and measurement techniques for acquiring physical, chemical, and biological data. Laboratory work will include chemical analysis of lake water, taxonomy and counting methods for aquatic biota, and experimental methods applicable to lake plankton communities. [Cost:2] [WL:1] (Lehman)

492. Behavioral Ecology. Biol. 152-154 or 195 (or the equivalent) and one additional course in zoology. (3 in Ann Arbor; 5 at Biol. Station, which also includes Biology 493). (Excl).

The objective of this course is to acquaint students with the subject of animal behavior. All types of behavior and their ecological ramifications are considered; both vertebrate and invertebrate examples are utilized. The course approaches behavior from a zoological viewpoint; emphasis is placed on understanding the methods of investigation used in the study of animal behavior. Consideration of physiological mechanisms is given, as well as discussion of the evolutionary framework in which behavior patterns evolve. The course is divided into two sections. In the first, the types of factors which affect behavior are discussed. During the second part of the course, functional categories of behavior (feeding, orientation, agonistic, sexual) are discussed with an emphasis on bringing together as many factors as possible in an attempt to understand the control (both proximate and ultimate) of these behaviors at all levels.

Although Biology 152-154 or equivalent are required, it would be best to have at least one of the following three areas before taking the course: genetics, ecology, or neurophysiology. Students who wish to obtain a more complete background should plan to take Biology 422 and/or Biology 494 either before or after taking Biology 492. Methods of instruction: (1) lectures are the primary means of instruction; (2) a text is also utilized, as are outside readings; (3) there is a midterm lecture exam and a term paper, as well as a final exam. Cost:2 (Hazlett)

498. The Ecology of Agroecosystems. A course in ecology. (3). (Excl).

An analysis of ecological principles as they apply to agricultural ecosystems, emphasizing theoretical aspects but also covering empirical results of critical experiments. While the emphasis is on principles, practical applicability is also explored where appropriate. Physical, biological, and social forces will be integrated as necessary. Designed as preparation for active research in agroecosytem ecology. Cost:4 WL:3 (Vandermeer)

514. Topics in Molecular Evolution. Biol. 305 and one upper level course in either molecular or evolutionary biology. (3). (Excl).

This year's topic is "Methods of DNA Sequence Analysis for Evolutionary Studies." We will cover such methods as estimation of nucleotide substitution rates, sequence alignment, and phylogenetic reconstruction using sequence data. We will review primary literature on these subjects as well as analyze sequences using various sequence analysis programs. The format of the course will include participation in group discussions twice weekly, individual class projects and class presentations. Cost:1 WL:3 (Tucker)

558. Aquatic Flowering Plants. Written permission of instructor and Biol. 459 or the equivalent. (3). (Excl).Meets a Biology laboratory requirement.

This course aims to provide familiarity with the local aquatic vascular plants (both submersed and emergent species), with the kinds of characters used in their identification (regardless of region), and with the natural history of these plants through field experience and indoor discussion-laboratory sessions. Adaptations to aquatic existence, pollination, aquatic "weeds," and uses of aquatics by wildlife and people are among the topics considered. The first five weeks consist of field trips, including one all-day Saturday trip to marshes of Lake Erie. Indoor discussions later in the season are thus based on some firsthand observation, although the field work is oriented primarily toward recognition of about 150 species. Indoor work includes identification of some additional species and consideration of other topics, aided by a study herbarium for the course, demonstration materials (dry, pickled, and fresh), color slides, and literature "on reserve" in the lab. Fassett's MANUAL OF AQUATIC PLANTS is the only required text; handouts include a bibliography and suggested readings, which are available in the lab. Checklists of expected species are distributed for each field trip. A hand lens is essential in the field. Grading is based on identification and essay/short-answer exams on general topics; there is no term paper. Enrollment is limited to eight, and a waitlist is maintained by the instructor (in 2012 NUB), from whom more complete information is available. Cost:1-2 WL:3 (Voss)
