Research Abstract |
The community compositions of harpacticoid copepods were studiedquantitatively around and within the Kuril Trench (490-7090 m) and the Ryukyu Trench(594-7150 m). Those compositions changed with water depth in both areas. Whileharpacticoid communities in shallower continental slopes in the two regions were similareach other, a lower similarity was detected between communities in the trench regions,which suggests those communities in trenches are isolated because of difficulties inmigration beyond bathymetric barriers such as island arcs.
