Martin Schader,Michael Rundshagene do not understand how and why a dam influences riverine macroinvertebrate assemblages. The purpose of this study was to clarify the influences of the Ooishi Dam (Sekikawa Village, Niigata Prefecture, Japan) on downstream macroinvertebrate assemblages with a particular focus on net-spinning caddisf

Martin Schader,Michael Rundshagenfrom the river to the drainage canal system and back to the former river. Even if biomass increases only in the drainage canal, the effect is limited. To enrich biodiversity in paddy fields, year-round water flows and natural materials in canal beds are important. However, information on the water v

Martin Schader,Michael Rundshagens most effective for biodiversity. To research this problem, I investigated the distribution and life history of aquatic animals in a consolidated paddy field. I surveyed various aspects of the paddy field, such as canal levels with the main, lateral and farm drains, areas with the presence or absen
