A reexamination of the taxonomical study of the genus Skeletonema and their spatial and temporal distribution in Japan

海洋硅藻属骨骼藻属广泛分布于世界沿海地区。我们从基因分析和形态观察中发现了东京湾的四个种(多赫尼亚种、日本亚种、热带亚种和J-d亚种)。对这些物种在不同水温和盐度下的生长速率进行了测量。多尔尼氏链霉菌的生长速度最快，生理特性类似于广盐性和广温性。日本血吸虫生长较晚，喜好低温环境。这些生理特征很好地反映了它们在东京湾的分布。

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.
