Outline and Purpose of the Course As any ecosystem has a vast chronological and spatial expanse, it is difficult to see the full picture through observation and experiments. This is where modeling and simulation become useful. We can understand the ecosystem's dynamics and predict the future by quantitatively expressing the reproduction/competition/food chain of living organisms. Students will learn about ecosystem simulation starting with the basics and go on to lean about predicting the future of environmental problems based on simulation. Students will also learn about the latest information technology, such as deep learning and big data, which serve as the basis for simulation and its analysis. As the mathematics involved will be explained in detail starting with the basics, even students who are not strong in math are encouraged to participate.
Course Goals To understand how to model the basic dynamics of an ecosystem.
To understand the role of simulation in the study of ecosystems.
To understand the role of data in the context of ecosystems and its analysis.
Schedule and Contents The course is delivered as a series of intensive lectures over five afternoons from Monday July 12 to Friday July 16 (there should be no timetable clash with lectures or student experiments in forestry science). The outline is as follows:

1 (Ise): Introduction ? the significance of ecosystem simulation and examples of use
2 (Ise): Population dynamics modeling I ? population dynamics and differential equation/density effect
3 (Ise): Community dynamics modeling ? inter-species competition and predation/prey
4 (Kobayashi): Population dynamics modeling II ? individual difference/seasonality/age structure
5 (Kobayashi): Evolution and population dynamics I ? the basic concepts in evolution and its modeling
6 (Kobayashi): Evolution and population dynamics II ? optimization and game theory
7 (Kobayashi): Species coexistence mechanism I ? complexity and stability
8 (Kobayashi): Species coexistence mechanism II ? environmental heterogeneity and niche
9 (Ise): Material circulation model ? stock/flow/retention
10 (Ise): Global environmental problems and simulation ? the Earth system model
11 (Ise): Information technology and ecology ? deep learning and data assimilation
12 (Ishihara): Big data and broadband integrated analysis/meta-analysis
13 (Ishihara): Publication and storage of data ? latest database developments
14 (Ishihara): Big data ? points to be noted and its potential
15 (all): Feedback
Evaluation Methods and Policy Assessment is based on attitude (20%, including class participation and responses to the set tasks) and the mini tests/mini reports (80%). Assessment criteria and policy are drawn from "Assessment criteria and policy" in the current version of the Faculty of Agriculture Student Handbook.
Course Requirements None
Study outside of Class (preparation and review) Be sure to read the textbook (in particular, Chapters 4-6) in advance.
