Preamble
This course provides a basis understanding of ecology and complexity in ecosystems. The course begins with a broad introduction to the definition of ecology and importance of ecological studies. It then explores the theoretical concepts that helped develop the basis for our current understanding of patterns in populations and communities and the relationships between biotic and abiotic factors in ecosystems. The more contemporary issues related to conservation biology, climate change impacts and the role of anthropogenic activities in alteration to ecosystem structure and function are also covered in this course.
