Course Learning Outcomes

This course aims to: 1. Provide a clear understanding and an up-to-date knowledge of basic concepts in ecology. 2. Outline the principles of ecology and its relevant applications. 3. Prepare the students to follow the sequence of ascending scale-beginning from individual organisms, proceeding through communities and ecosystem to global consideration of biogeography, correlation and conservation and to study the ecosystem of Pakistan and to identify its environmental issues.
