Ecology & Environment

Ecology & Environment BSS.509 3 Credits
Course Logistics

This twenty-weeks long course is designed to lay foundations of Ecology & Environment with special emphasize on marine estuarine and limnetic ecosystems.

Reading
One particularly exciting feature of our course is the free in-course textbook materials. This textbook is not required, but it should be helpful to students who want to read more detailed explanations or additional examples or who want to delve more deeply into topics that fascinate them. Please note that access to the textbook is available only for the duration of the course.  

Exercises

Short ungraded exercises will occasionally be embedded into lectures. Each lecture will be followed by ungraded exercises. Answers to these exercises will be given and explained after you reply to the questions. These exercises do not introduce new material, but they enable you to check your understanding of the lectures. If you miss too many of the exercises after a lecture, then you might want to listen to that lecture again.

Time Commitment

You should expect to spend on about 3 hours per week taking the lectures, another 2 hours per week doing the exercises, and about 1 hour on each quiz. You might want to spend additional time doing the reading and participating in the discussion forums.
