Objectives of the Course

To teach the importance of biological indicators in the assessment of ecosystems by examining the responses of living organisms to environmental changes, and to enable students to develop the ability to interpret nature, recognize environmental problems, and gain awareness of sustainability.

Course Content

This course examines how nature can be interpreted and ecosystem health can be assessed through the responses of living organisms to environmental changes. The use of various groups of organisms as biological indicators will be explored, and their roles in determining air, water, and soil quality will be evaluated. In addition, contemporary environmental issues such as climate change, environmental pollution, biodiversity loss, and sustainability will be discussed from the perspective of biological indicators.

Name of Lecturer(s)
Learning Outcomes
1.Explain the concept of biological indicators, their historical development, and their importance in environmental assessment.
2.Compare and illustrate the use of different groups of organisms (cyanobacteria, protists, fungi, lichens, plants, invertebrates, and vertebrates) as biological indicators, supported by relevant examples.
3.Evaluate environmental processes such as ecosystem health, pollution, climate change, and biodiversity loss through the use of biological indicators.
4.Interpret biological indicators used in agricultural, urban, and natural ecosystems and analyze the causes and consequences of environmental changes.
5.Relate traditional ecological knowledge to modern biological indicator approaches and develop recommendations for environmental monitoring and sustainable ecosystem management.
