In the broad and varied areas from mountainous zones to coastal zones, a lot of activities of human beings have been continued for a long time in various intensities. As a result characteristic ecosystems have been formed by the interaction between nature and human beings and/or by the coexistence of human beings and nature. This ecosystem is under the strong influence of human livelihood, specifically in the forms of agriculture, forestry, fisheries and so on, and also involves the villages, towns and cities that are human residential areas. The understanding of these ecosystems, which is one of the main subjects of this division, leads the solution of essence to the global environmental problems. Here we are trying to analyze interactions between human activities and nature, and practicing the education and research to build up the coexistence system.


Where, when and how the human ecosystem has evolved from the nature ecosystem and how the human ecosystem should be managed in relation to nature ecosystem conservation are studied in this laboratory. The modes of vegetation evolution and domestication continua from the wild to the weed, the encouraged, the semi-tamed to the tamed in the human ecosystem of Asian civilization and regional cultures are also field-surveyed.

■Associate Professor


The main recent research activities have included: (1) field and laboratory studies on the life history and ecology of fish and invertebrates, (2) systematics of marine fish, (3) studies on environments and biological production systems in coastal waters, and (4) current interests which have been expanded to include an elucidation of the effects of human activities on terrestrial areas to coastal ecosystems through river discharge. This laboratory consists of the Maizuru Fisheries Research Station and educates graduate school students of the Graduate School of Agriculture.
