Ichiro Tayasu is studying isotope ecology on watersheds (both terrestrial and aquatic ecosystems). I am currently studying the earth systems from a point of environmental isotope study.

Recent Activities

I am currently studying ecology and environmental science using “multi-isoscapes”.

Message to Students

Isotope signature contained in living organisms is a useful proxy to bridge between organisms and the environment.
I use the method in various research fields covering terrestrial and aquatic ecosystems. The approach can be used in the study of food webs, material cycling, animal movement, etc.
