Course Objectives

The course examines the unique ecological roles of insects and considers aspects of insect biology as they relate to relationships between individuals and populations and their environment. Students will learn key elements in these relationships, with a particular emphasis on current areas of controversy. Also, students will learn techniques used in ecological studies on insects.

Course Activities

Lecture, outside readings (book chapters, reviews, and selected original literature), paper reviews for in-class discussion, computer exercises and problem sets from Analyses in Insect Ecology and Management (for graduate students only, undergraduates may complete these for extra credit), regular essays (6-7), and three exams. Essays are due one week after assigned. Late assignments will be reduced in grade, unless excused by the instructor.

Grading

Examinations - Exam coverage will include all lecture material including the lecture immediately prior to the exam, unless otherwise announced. The final is not comprehensive. Exam format primarily will be short answer and essay, and exams (including the final) will be take home.

Class assignments and participation400 (approximately)
Exams (3 exams with 100 pts/exam)300
Total700

Letter grades will be assigned based on a scale no harsher than straight percentages of 100-90% A range, 89-80% B range, etc.; however, I reserve the right to use a more lenient grading scale.
