Biological Communities in Aquatic and Terrestrial Human-Mediated Environments

The fauna and flora in freshwater systems has been affected by long years of human activity. Especially in Japan, people have converted the land to paddy fields and expanded artificial water systems consisting of paddy fields, ditches, and irrigation ponds that function as shallow wetlands and streams. Such human-maintained artificial water systems sustain aquatic biological communities and serve to compensate for the loss of natural wetlands. The manner of this maintenance has changed in line with social development. The landscape and environment of rivers and lakeshores have been significantly modified by construction work designed to prevent floods, possibly causing difficulties for animals migrating through the watercourse. Hence, I currently pay much attention to the ecological mechanisms that exist between human management as an intermediate disturbance of the environment and the response of aquatic animals—such as fish and aquatic insects—and terrestrial invertebrates in the Satoyama area.

Habitat utilization and community structure in aquatic environments

Animals cohabit in a habitat with complex relationships each other. Through the interactions between individuals of same and different species, there should be mechanisms that promoting the coexistence of animals at the species and individual levels. My current theme is to clarify those mechanisms by analyzing the individuals' habitat utilization and their interactions in relation to the habitat structure. The communities dominated by cichlid fishes in Lakes Malawi and Tanganyika are the favourable materials for this theme, because the cichlids in the lake are of closely related species in a evolutional sense. A further interest is the relationships between the specific benthic and fish communities through the prey-predator relations, such as shrimps and shrimp-eating cichlid fishes. The benthic communities including fish and molluscan in Lake Biwa as well as Lake Baikal are also interesting in comparison to those in Lakes Malawi and Taganyika. These three lakes are ancient ones in the world, and have the specific community structure with many endemic species, respectively.
