DIVISION OF MARINE ECOSYSTEM


This division carries out various aspects of research and education in basic biology such as taxonomy, evolutionary biology, developmental biology, physiological ecology and biogeography from the molecular level to the ecosystem level using mainly temperate marine invertebrates as materials. Moreover, through extension of research fields into the global scale from tropical to boreal regions, the division also covers biology that has applied aspects such as environmental and conservation biology as subjects of research and education.

LABORATORY OF MARINE BIOLOGY

The laboratory addresses the question of how diverse marine organisms are, and evolve throughout the time, from a view point of natural history sciences. This includes comparative morphology, development, systematics, phylogeny, biogeography, and phylogeography of marine organisms by both morphological and molecular level methods. The laboratory also carries out research on conservation biology of marine organisms of various taxonomic groups from a view point of environmental change and the biotic responses. Seto Marine Biological Laboratory provides this program to undergraduate students in Faculty of Science and students in Marine Biology Course, the Graduate School of Science.

LABORATORY OF FISHERIES AND ENVIRONMENTAL OCEANOGRAPHY

We study to clarify the aquatic ecosystem that maintains the sustainable fisheries production, the mechanism of the change of the ecosystem and the behavior ecology of fishes and aquatic mammals in the aquatic biosphere including marine and fresh waters. In order to research these topics, we perform the stable isotope analysis, the simulation using ecological models and bio-logging techniques including biotelemetry and micro-data loggers. This laboratory is a temporary cooperative laboratory from the Graduate School of Agriculture.
