Ecology is the study of interactions between organisms and environment.
In the beginning of this course, we will explore biotic and abiotic components of ecosystems. Next, the concept of energy as a currency in modeling ecosystems will be introduced to students. Structures and functions of populations, communities, and ecosystems are the main themes for the course. In summary, students are expected to learn fundamental principles, theories, models, and mechanisms in ecological studies. I hope that next time when you visit the national parks, you will not only see the beauty of the nature, but also sense vigorous interactions, visible and invisible, among organisms and environment.
