Special workshop on algae for elementary school students（ひらめき☆ときめきサイエンス開催，2回目）

Second day of the special workshop on algae for elementary school students has successfully finished. Students made own seaweed exsiccatae that comprise more than 30 specimens. In Japan, elementary school students have to conduct a "research" in the any field of science during the summer break. This exsiccatae will be submitted to the school as the report of their research.
We have received the grant for this workshop from JSPS in the past four years.

日本学術振興会ひらめき☆ときめきサイエンスの2回目が本日開催され，30名の子どもたちが世界でひとつだけ，自分だけの「海の森図鑑」を完成させました。

この事業は，文科省の競争的研究資金である科研費の研究成果を教育に還元するプログラムで，全国の大学や研究機関で約180課題が採択されています（この公開講座自体も競争的資金）。海藻研がこのプログラムに採択されるのは4年連続です。

Terada, R., Watanabe, Y., Fujimoto, M., Tatamidani, I., Kokubu, S., Nishihara, G. N. 2015.
The effect of PAR and temperature on the photosynthetic performance of a freshwater red alga, Thorea gaudichaudii (Thoreales) from Kagoshima, Japan
Journal of Applied Phycology DOI: 10.1007/s10811-015-0660-z

Thorea gaudichaudiiシマチスジノリ

http://link.springer.com/article/10.1007/s10811-015-0660-z

Thorea gaudichaudii is a freshwater red alga that is distributed in the freshwater spring in the islands of tropical western Pacific including Ryukyu Archipelago. This species can be found in well-shaded freshwater spring without direct sunlight. We elucidated the irradiance and temperature environment of the habitat, and reported the characteristic photosynthetic performance of this alga.
This is the sixth article from our lab.

2nd day in Hyogo（WS2日目）

On the second day, annual monitoring survey was successfully done in Takeno that is facing to the Sea of Japan. Fortunately, there was calm waters under the fine clear sky.

Workshop for the seaweed survey in Kobe University（神戸大の藻場モニタリングワークショップに参加）

Two students of our lab participated with a workshop that was held at Kobe University. This WS was held as the joint activity of the annual survey for the long-term assessment of natural seaweed communities (Grant from the Ministry of Environments).

For this survey and WS, more than ten phycologists and students from five different institutions were participated. As the first day, we conducted the field survey at the site in Awajishima-Island that is facing to the Kitan Straits, Pacific Ocean.

New Article: Sargassum fusiforme（ヒジキの光合成に関する論文）

Our lab's new paper was published from Phycologia!

We have reported the photosynthetic characteristics of an intertidal brown alga, Sargassum fusiforme, based on the in vitro and in situ measurements. Indeed, it was quite hard work SCUBA diving from before sunrise and through the sunset, but the data we collected were absolutely great. From the figures in our article, you can clearly see the characteristic decline of the effective quantum yield during the day and under strong irradiance.

Meeting in Shanghai

The 2nd International Symposium of Aquaculture and Fisheries Education (ISAFE2) was held last week at Shanghai Ocean University, China, and from our lab, Ryuta Terada was invited as a special session speaker.

Namalionopsis tortuosa（オキチモズクの調査）

A survey of freshwater red algae including Nemalionopsis tortuosa was carried out. This species can be found in shaded areas of irrigation canals; however, confirmed habitat is limited, and only around twenty sites have been recorded from Kyushu, Shikoku and Okinawa Islands. Presently, this species is registered as an endangered species by the Japanese Ministry of Environment.

Nemalionopsis tortuosa

Characteristic ecology and photosynthetic performance of this species were recently reported from our group.

Summary

薩南諸島における海草の分布

2012年に水産増殖（日本水産増殖学会）から刊行された研究室の論文がオンラインでダウンロードできるようになりました。
この論文では，薩南諸島（種屋久，奄美群島）における熱帯性・温帯性海草の分布状況を明らかにしました。熱帯性の海草は沖縄以南，温帯性海草は九州以北でよく調査・研究されていますが，奄美群島や種屋久は情報が不足していました。各種の分布図から，この地域が温帯性・熱帯性海草の分布推移帯（エコトーン）であることがよく分かります。

Pyropia tenera survey in Kumamoto（熊本でアサクサノリの調査）

Field survey of an endangered alga, Pyropia tenera, was conducted at a site in Kumamoto Prefecture.

Pyropia tenera　アサクサノリ

This species is known as an edible alga in Japan. However, due to the loss of the habitat, extinction of the natural population has also been seriously concerned.
Characteristic photobiology of this species was recently reported by our team.

Porphyra survey at Minami-Satsuma City（坊津で坊ノリの調査）

Field survey of Pyropia (= Porphyra) was conducted at a rocky shore in Minami-Satsuma City, Kagoshima Prefecture. Fortunately, we found a big Pyropia population on the rocks in the upper intertidal zone facing the East China Sea. Indeed, rocks were mostly covered by the alga. 
薩摩半島南西部にある南さつま市坊津でアマノリ類の調査を行いました。この種は地元で「坊ノリ」と呼ばれており，波あたりの激しい沖合の瀬に生育しています。数年ぶりに来ました。

This alga, known as Bo-Nori for local people, was formerly harvested by fishermen in Winter, and was indispensable to their dietary culture.
