Unit 2400: Ecological Research Methods

1. Introduction to Ecological Research Methods

• Importance of ecological research in environmental science and management
• The scientific process in ecology: observation, hypothesis, experimentation, and conclusion
• Overview of research methods: observational, experimental, modeling, and comparative studies

2. Experimental Design in Ecology

  • Hypothesis formulation and types (null, alternative)
  • Variables: independent, dependent, and controlled
  • Replication and randomization
  • Control groups and treatment groups
• Statistical considerations in design
  • Sample size determination
  • Avoiding bias and confounding factors

3. Field Sampling Techniques
