The Seto Inland Sea--eutrophic or oligotrophic?
The present water quality conditions in the Seto Inland Sea of Japan are described along with an historical background before and after the measures taken to reduce eutrophication. The directive to reduce phosphorus discharge into this area was very effective, reducing the number of red tides from about 300 cases per year at their peak in 1976 to the recent level of about 100 cases per year, in...
متن کاملCoexistence between Zostera marina and Zostera japonica in seagrass beds of the Seto Inland Sea, Japan
Background: There have been many studies on the growth conditions of Zostera marina and Zostera japonica, but few studies have examined how spatial and temporal factors affect growth in established seagrass beds or the distribution range and shoot density. This study aims to clarify the factors that determine the temporal and spatial distribution of Zostera marina and Zostera japonica in the Se...
متن کاملAcoustic measurement of the net transport through the Seto Inland Sea
The net transport through the Seto Inland Sea, associated with the inflow of the Kuroshio Current from the Pacific Ocean, is the focus of this study. Direct measurement of the net transport was successfully accomplished during February–November 2012 using reciprocal sound transmissions in the Akinada Sea, the western part of the inland sea, while accurate transport was estimated only from mid-A...
متن کاملA new species of Enterognathus (Copepoda, Cyclopoida, Enterognathidae) collected from the Seto Inland Sea, western Japan
A new species of the endoparasitic copepod Enterognathus (Cyclopoida, Enterognathidae) is described from a crinoid host in the Seto Inland Sea, western Japan. This is a third species of the genus and its first occurrence in the Pacific Ocean. The new species is distinguished from two previously known congeners by the morphology of the body somites, caudal rami, antennae and legs. Crinoid parasi...
متن کاملComplex environmental factors affecting the decline of Pinus densiflora in the Seto Inland Sea area of western Japan
This study reconsidered the cause of forest decline of Japanese red pine (Pinus densiflora Sieb. et Zucc.) in the Seto Inland Sea area, western Japan. Although the decline in pine forests was attributed to pine-wood nematode infection, the stress of air pollution was also shown to have negative physiological effects on pine needles. Secondary pollutants related to NOx accumulate in the morning ...
