Term Paper due April 18

Structure of the Course: I will deliver informal lectures Mondays and Wednesdays. In the latter half of class on Wednesdays we will discuss the assigned papers. The lab on Fridays will involve field exercises. Bring a field notebook, and dress for work in the woods or swamps. Note that class participation counts; I encourage discussion. In addition to tests you will be responsible for four 2-page creative essays on themes arising from the papers we read, and for a 7-10 page term paper on an ecological topic of your choosing. Note the due dates in the syllabus. Examples of good papers will be available for your examination.

Grading: Your performance will contribute to your final grade in the following manner:
2 tests 11% each
final exam 20%

3 2-page essays on
themes from readings 6% each

7-10 page term paper 20%

Class participation, lab
and homework 20%

Revised 3-5-1997.
