Environmental Studies 89: Forest Biogeochemistry
X-hour: Wed. 4:15-5:20pm
211 Steele Hall: 646-3609
Office Hours: T 10-11; W, F 2-3
and by appointment
Articles from the scientific literature
Required Reading articles are on reserve in Kresge Library.
Terrestrial Ecosystems. J.D. Aber and J.M. Melillo. 1991. Saunders College Publishing. 429 pgs.
This course will examine elemental cycling and related biogeochemical processes in terrestrial ecosystems, with a primary focus on forests of the temperate zone. We will cover many aspects of major and trace element cycles. The impact of air pollution on elemental cycling processes will be an area of interest throughout the term.
The required text will serve as a useful reference. There are no assigned pages--you are expected to find the appropriate sections for each topic and read them. I will be glad to provide guidance to anyone who wants help determining the reading for a given week. This class will be taught somewhat like a "graduate seminar." More class time will be spent discussing articles from the peer-reviewed literature (with presentations by members of the class) than in lecture.
Three problem sets (20 points each)
Final paper (15-20 pages)
Note: I am interested in creating a Forest Biogeochemistry informational web page as part of the Environmental Studies Program web site. Members of this class who want to work on this project with me can do so: If we have enough interest in the class, I would consider ~5 page papers with figures and web-appropriate features placed on the web in lieu of the 15-20 page final paper. We will talk more about this on the first day of class.
I encourage students with disabilities, including "invisible" disabilities like chronic diseases and learning disabilities, to discuss with me after class or during my office hours appropriate accommodations that might be helpful to them.
