サガラメは日本固有種で新種Eisenia nipponica であるという内容の論文

サガラメにはEisenia arboreaの名前が充てられてきましたが,北米のEisenia arboreaとは異なることが明らかになり,新種Eisenia nipponicaが記載されました。サガラメは静岡県御前崎から紀伊半島に生育する固有種ということになります。

New article: Meristotheca papulosa トサカノリは緑色光や青色光だけでも十分に光合成が可能で、緑色光を当て続けると赤みが増す論文

Our new article out from the Journal of Applied Phycology.
Despite the absence of red light that is essential to the photosynthesis by chlorophyll-a, a deep subtidal red alga Meristotheca papulosa can photosynthesize effectively by using the green light that penetrates into the subtidal water. Under the blue and green light exposures for 7-day culture, a phycobilisome, phycoerythrin (PE) concentration of the alga increased, suggesting improved reddish-color the alga.
