This course unit provides the students with key knowledge on a large scientific area focusing specially on six themes: Ecosystems, Energy in ecosystems, Biogeochemical cycles, Biological communities, Population Ecology and Community Ecology. In each theme concepts are explained in a simple yet detailed way, allowing the students progression into more complex subjects introduced by each following chapter.
During the progression of the study on the basis of e-learning the are some activities and exercises on the themes so that students can, by themselves, evaluate the way they apprehended the themes.

Since Ecology is a vast science in constant evolution the teacher makes an effort to publish, when possible, monographies that bring the subjects up to date.
