Outline and Purpose of the Course	There are numerous interactions between animals, plants and their environments that are mediated by “signal substances” such as attractants, repellents and toxicants. This lecture covers the chemical basis of biological interactions and their ecological significances in the ecosystems. The subjects include biological functions of pheromones and other semiochemicals, methods of chemical analyses, syntheses and applications.
Course Goals	Study the leading examples of biological interactions mediated by chemical substances and understand the basics of such interactions.

Functions of signal substances 　?Pheromones (activating factors related to recognition of the opposite sex, assembly, dispersion, etc.) 　?Allelochemicals (chemical factors related to host plant recognition, defense, symbiosis, etc.) 　?Utilization and prospects of signal substances 3. Evolutionary background to signal substances 　?Evolutionary process of chemical exchange 　?Secondary metabolites as chemical barriers: competitive coevolution 　?Evolution of flower color and scent related to pollination: cooperative coevolution 4. Biosynthesis and recycling of physiologically and ecologically active substances 　?Biosynthesis of plant and animal secondary metabolites 　?Biological concentration in food chains 5. Dynamic aspects of signal substances 　?Effectors affecting plant metabolism 　?Ecological significance of effectors 6. Analysis methods for physiologically and ecologically active substances 　?Ultratrace purification, isolation, and detection methods for physiologically and ecologically active substances 　?High-resolution spectral analysis method 7. Summary 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 8. The course will be held over two days on a Monday, from 1st to 6th period, and a Tuesday, from 4th to 5th period.
Evaluation Methods and Policy	In-class quizzes and reports
Course Requirements	Familiarity with basic organic chemistry is desirable.
Study outside of Class (preparation and review)	Students are expected to review course materials to acquire the perspectives and approaches of organic chemistry established in chemical ecology. Students are encouraged to make an active effort to find ways to apply the knowledge they have acquired to their own research projects.
