335. Chemical Ecology
This course explores how organisms use naturally occurring chemicals to influence ecological
interactions. Case studies will illustrate both interspecific and intraspecific interactions among
plants, insects, animals, and microbes, including behaviors such as mate selection, colony
organization, and defense. Some attention will be given to the biochemical origins of these
compounds. Prerequisite: BIO 205. Alternate years.

337. Entomology
The evolutionary history, morphology, taxonomy, physiology, ecology, behavior, and economic
importance of insects. Laboratories will focus on sampling, preservation, identification, and
experimentation with insects. Field trips may extend beyond normal class hours. Prerequisites:
BIO 211 or BIO 141, 142, and permission of instructor. Offered every third year. (Laboratory

381-385. Advanced Topics in Biology
Advanced examination of a selected topic of current interest or concern in biology. See Topics

399. Preservation Ecology Summer Internship
Field experience during the summer under the auspices of the Iowa Nature Conservancy in
preservation ecology techniques, including biological resource assessment, monitoring animal
and plant populations, landowner contacts, mapping, preparing reports, and designated
preserve management tasks. Prerequisites: (1) at least five term credits in Biology; (2) at least
two of the following: BIO 209, 254, 308, 312, 321, 332, 334, or 337; (3) junior standing; and
(4) acceptance by the Nature Conservancy.

483. Senior Seminar in Biology
Readings, presentations, and discussions from the recent research literature focused on an area
of interest and/or expertise of the instructor. Prerequisites: BIO or BMB major and senior
standing. Recommended prerequisite: BIO 315.

485. Biological Problems
Investigation of a biological problem, including a review of the literature, collection and
interpretation of data, and writing of a research report. May be repeated once for credit.
Intended for seniors or advanced juniors, this is a capstone experience for Biology majors.
Arrangements must be made with the instructor before registering.

511. Extended Research in Biology (1/4)
Reading in depth on a topic of current interest and the pursuit of an experimental or theoretical
problem related to the topic. This adjunct course must be taken over four successive terms.
Prerequisite: permission of instructor.
