Chemical Ecology

Course Description

Course information provided by the 2026-2027 Catalog.

Why are chilies so spicy? This course examines the chemical basis of interactions between species and is intended for students with a basic knowledge of chemistry and biology. Focuses on the ecology and chemistry of plants, animals, and microbes. Stresses chemical signals used in diverse ecosystems, using Darwinian natural selection as a framework. Topics include: plant defenses, microbial warfare, communication in marine organisms, and human pheromones.

Learning Outcomes

• Categorize ecological interactions and potential mechanisms by which they are mediated.
• Discuss these mechanisms in light of evolutionary theory and draw conclusions about potential agricultural applications.
• Become familiar with the general structures of organic molecules and the relationship between structure and function.
• Become familiar with a number of analytical, behavioral, and experimental techniques used to analyze chemical compounds that mediate ecological interactions.
• Read and synthesize findings from original scientific research in chemical ecology by studying and discussing the primary literature.
