Course Philosophy

Course goals and style: This is a course that will emphasize models in a study of population ecology. In particular, model formulation, solution, and interpretation will form the major portion of the lecture material. A critical examination of assumptions of models will be stressed. The reading will in general emphasize more of the experimental and natural history aspects. This division is made primarily for pedagogical reasons.

I expect that after completing the course a student will have an understanding of the major conceptual issues in population ecology and the role of models in developing questions, and interpreting experimental results. Additionally, I expect that a student would be able to read critically a large portion of the papers involving models appearing in journals like THE AMERICAN NATURALIST. To achieve these goals, I will develop a number of mathematical tools in class.

I will use frequent homework assignments as an integral part of the course. Once per week we will meet in the computer lab.  We will use excel spreadsheets that have been developed expressly for the course where you simply have to enter numbers into forms.

Term paper:

The term paper will be due on the last day of classes BY E-MAIL (NO EXCEPTIONS), March 12, and can be on any topic related to the subject of the course. The format will be either i) an original piece of work, ii) a critical review of a single paper (e.g. Menge 1995 in the reading), or iii) a synthesis of work in an area (e.g. MacCallum and Dobson 1995 in the reading). The paper should have a length of 10-15 double spaced pages. An outline will be due on Feb. 12. One way to get ideas is to look at recent issues of American Naturalist, Ecology, Journal of Animal Ecology or other journals (see list at end of this page). 

Any topic that is part of the course subject matter is fine.  You will be expected to demonstrate a good understanding of the topic you pick, and to write well.  

If you choose to do an original piece of work, you should either create and analyze a model or analyze data that explores some area of population biology.  

It is important to remember that a critical review of a single paper will draw upon ideas and aspects outside the paper under consideration, and that you will have to explain clearly the ideas in the paper as well as how they fit into a larger context, and any potential shortcomings, as well as why the paper is important and or interesting.

For the synthetic review, your term paper needs to be something where the whole is greater than the sum of the parts -- you need to present new ideas that come from putting several papers together.

As noted, the examples above should give you an idea of how to get started.

The outline will not be graded, but is an opportunity for me to give you feedback (and prevent you from waiting to the last minute).  I will send you an e-mail that you can respond to to provide the outline.  

If you have any questions, do ask!
