SOME INFO
• Textbook: The following textbook is recommended but not required: A Primer of Population Ecology, N. Gotelli
• In addition, copies of relevant original articles will be available via our website.
• Tutorial outline Each week, a portion of the tutorial will be allotted to discussion of and questions pertaining to the current lecture.

SOME INFO:II
• Article reports Each student will prepare 2 written reports on current journal articles of his/her choice. Reports should be less than 3 pages in length and typed if possible. Reports will be graded on (i) demonstration of understanding of the article, and (ii) quality of the written report. The following journals are suggested sources for articles:Ecology, Ecology Letters, American Naturalist, J. Animal Ecology J. Theoretical Biology, Oecologia, Theoretical Population Biology, Oikos, etc.

SOME INFO:III
Assignments Each student will be provided several problem sets during the semester. The sets are meant to provide "hands-on" experience with quantitative analysis. Completed assignments should contain all of the analysis. Final solutions alone will be judged insufficient. Late submissions will be docked 5% per day.

POPULATION CURVES
• Total Population Curve: total number of individuals vs. time
• Partial Population Curve: # of individuals of each life stage vs. time

SIMULATION 1
• Three stages: egg(3), larva(3), adult(1)
• All individuals live full life
• Recruit eggs every day via random draw (0,20)
• Calculate number of insect-days
