| Research Abstract |
Marine diatom genus Skeletonema is widely distributed in coastal areas around the world. We showed that the four species to appear from gene analysis and morphological observation in Tokyo Bay(S. dohrnii, S. japonicum, S. tropicum, and S. j-d). For these species, the growth rate of various water temperature and salinity were measured. The highest growth rate was showed in S. dohrnii, and physiological charactaristics were liked to be euryhaline and eurythermy. S. japonicum was late growth than previous specie, and prefer a low temperature. These physiological characteristics were well reflected their distribution in Tokyo Bay.
