Environmental Biology

 KAWASHIMA Hiroto
Course description
Environmental biology is the study of the relationship between the environment and organisms, and the material cycle on Earth. Stable isotopes, which are closely related to living organisms, reflect environmental effects. Students will learn about the latest analytical methods for stable isotopes and the applications of stable isotopes in the fields of biology, food, and the environment.
Purpose of class
The environment in which organisms and humans live is based on a complex interaction of chemical, physical, and biological factors. The objective of this class is to enable students to explain the basics of ecology, material cycles, and the latest stable isotope research.
Goals and objectives
  1. Understand and explain the relationship between the environment and organisms
  2. Understand and explain material cycles
  3. Understand and explain stable isotope ratios and their applications

Evaluation method and criteria
Students will be evaluated on the basis of regular points from intermediate exam and mid-term examinations, and final examinations. A total score of 60 points or higher is required to pass the course. Questions will be designed so that 80% of the students will be able to obtain a score if they fully understand the lecture content. Attendance will be checked by ID card.
