Benthos Ecology


Benthos Ecology laboratory has an objective to understand the complexities of aquatic animal life and to apply them to human systems through the study of their ecology and other relevant environmental factors using various methods from multiple approaches.

1) Application of freshwater organisms as environmental indicators and for ecological restoration (Kawai, K.)

2) Predatory organisms of tidal flat clams and population ecology of lancelets (Saito, H.)
