BIOL 368 (NJIT) and 28:120:368 (Rutgers)
Ecology and Evolution of Disease
Fall 2008

Introduction

Ecology and Evolution of Disease addresses those aspects of ecology and evolutionary biology most relevant to understanding the origin, dynamics and treatment of disease (both infectious and hereditary/genetic). The class will be a mixture of lecture and discussion of case studies, including topics of current interest. Material covered will include biology, mathematical models, and some aspects of human behavior.

This course is aimed squarely at pre-med students, including those in the Accelerated Programs, although it is open to all with the necessary biology background.

Course details

Credits: 3

Prerequisites: General Biology I and II (or equivalent with permission). These are required courses for all Biology majors. The basics of cell biology and genetics are absolutely necessary, as is a basic ability in mathematics so that model formulations can be followed. Calculus I is strongly recommended.

Schedule: Class meets Tuesday and Thursday, 11:30 to 12:55, in 207 FMH (Faculty Memorial Hall) on the NJIT campus.

Office hours: After class on Thursdays, or by appointment.

Grading and exams

There will be two exams, a mid-term and a final, and at least one in-class quiz. The grading will be as follows:

Component
Grade percentage
Quiz
10
Mid-term exam
30
Final exam
30
Participation in class
30

Please note that in-class participation is very important! It means doing the readings, coming to class prepared with notes, questions, and ideas, and engaging in discussion. If you sit in the corner and don't say anything until asked, or if it transpires that you haven't done the reading, then you will not do well in this class. You will get three scores out of 10, after 5 weeks, 10 weeks, and at the end of the semester. The sum of these will be your participation score. Individual scores greater than 10 are possible if your participation is exceptional, but your final score cannot be greater than 30.

Textbooks

Both of these are required.

  • Evolution of Infectious Disease by Paul Ewald. ISBN 9780195111392.
  • Infectious Disease Ecology by Ostfeld, Keesing and Eviner. ISBN 9780691124858.

Example exam question

The mid-term and final exams will be short- and long-answer form. Here is an example of how a question might be worded. I would expect you to take approximately 30 minutes to answer a question like this.

  • We have studied two examples of interacting disease pairs: Sickle-cell Anemia/Malaria and Measles/Whooping cough. Compare and contrast the ways in which the diseases within each pair interact. (For example, what aspect of each disease’s life history does the other one influence?)
