This laboratory is concerned with ecological and physiological studies of such things as the distribution, production and temporal variations in density of plankton and micronekton in the sea. The role of plankton in the function and structure of the marine ecosystem as a whole is also studied.

1. Interaction between bathy and epipelagic ecosystems

One of our topic is energy and material flow in the ocean through the interaction of prey and predator. In this context, we are analyzing the biomass, production, and vertical distribution of each plankton groups from the surface to deep sea. Furthermore, we are studying gut content, stable isotope, and enzymes to clarify the interaction between them.

2. Why so many species of plankton?

Ocean ecosystem is constituted by wide variety of lives. To study this system, systematics is fundamental. We are continuously revising the species description and systematics of major plankton and micronecton groups.  

3. Life history of each species

We are analyzing distribution, life history, food habit, and population dynamics of major plankton and micronecton species. One of our goal is to clarify their roles in the ocean ecosystem.

4. Functional morphology of plankton

We are studying the feeding and mating behavior of plankton and micronecton. Feeding and sensory apparatus are analyzed using scanning electron microscope and transmission electron microscope.

5. Environment and ocean bioproduction

Plankton play the impotant role in the carbon dioxide cycle.
