褐藻アントクメEcklonia radicosa（コンブ目）の標本や記録における分布南限は，種子島の西方に位置する馬毛島沖ですが，1971年の標本以降生育が確認されないままでいました。本種は馬毛島周辺海域から消失した可能性が考えられてきましたが，2023年10月7日の調査航海で実施したドレッジ調査において，本種の生育が改めて確認されました。

A special workshop on making seaweed specimens for elementary school kids

We held a special workshop on making seaweed specimens for elementary school kids as an event during their summer holidays. On the first day, July 20, we pressed samples of 30 species collected during our field surveys, including some edible species like Nori and Wakame. Next weekend, after fully drying the samples, we will have the second day of the workshop, making herbarium specimens to complete their own exsiccatae. This workshop was conducted with funding from KAKENHI, provided by the Japan Society for the Promotion of Science (JSPS).

 

Second Jeju International Island Symposium

Professor Ryuta Terada, the head of the Marine Botany Laboratory, was invited to the 2nd Jeju International Island Symposium as one of the speakers. The symposium was held from July 9th to 11th in Jeju City, Korea. He presented the status of the nationwide long-term monitoring survey known as "Monitoring-Site 1000" in Japan over the past 15 years. As Jeju Island and Kyushu Island are very close, with a distance of around 200 km between them, we believe our concerns about the degradation of seaweed communities observed in Kyushu may be helpful in considering the possibility of future changes in seaweed communities on Jeju Island. We express our thanks to the organizing committee of this symposium for inviting him to this wonderful opportunity.

Terada, Yoshizato, Murakami, Nishihara 2024. Phenology and the response of photosynthesis to irradiance and temperature gradient in the herbal drug red alga, Chondria armata (Rhodomelaceae, Ceramiales) from Kagoshima, Japan.

Journal of Applied Phycology

DOI: 10.1007/s10811-024-03250-w

 

This alga has been utilized by local inhabitants for many years in the Ryukyu Islands, serving as an herbal drug for anthelmintic purposes, effectively eradicating various intestinal worms such as parasitic roundworms, whipworms, and tapeworms. 

 

In the present study, we conducted a seasonal field survey to elucidate the seasonal variations of this alga in Kagoshima, Japan. Additionally, we conducted experiments to analyze the photosynthetic response of C. armata under varying temperature and irradiance gradients. This endeavor aims to enhance our understanding of the optimal and critical environmental conditions for this alga near the northern distributional limit in the Pacific.

The Takeno and Awajishima surveys

We participated in field surveys for the nationwide long-term monitoring project known as 'Monitoring Site 1000,' conducted at Takeno in Toyooka City, facing the Sea of Japan, and at Awajishima Island in Sumoto City, facing the Pacific Ocean, both located in Hyogo Prefecture.

 

 

These surveys were conducted by the Kobe University Research Center of Seto Inland Seas (KURCIS), and phycologists from the Japan Fisheries Research and Education Agency, as well as those from our laboratory, were invited as specialists.
 

9th Asian Pacific Phycological Forum (APPF2024)

The 9th Asian Pacific Phycological Forum (APPF2024) was successfully closed except for the excursion that is conducted today. As one of the co-chairs of the LOC, Ryuta Terada wishes to express sincere thanks to all participants, the LOC, and staff members who contributed to the conference. The next meeting will be held in April 2027 in Ho Chi Minh City, Vietnam.

New Assistant Professor

The Marine Botany Lab of Kagoshima University welcomes Dr. Masahiro Suzuki, who has been newly appointed as Assistant Professor. His specialty lies in the taxonomy and systematics of macroalgae, particularly marine and freshwater red algae. He will conduct research and education for undergraduate and postgraduate students alongside Professor Ryuta Terada and Associate Professor Hikaru Endo.

ノリ養殖の採苗は，地先水温の状況を見ながら事前に採苗日を決めておき，採苗日に胞子体（牡蠣殻糸状体）の殻胞子の放出のピークが来るように放出誘導をします。しかし，台風等の荒天で採苗日を数日延期せざる得ない年が稀にあります。このような場合，殻胞子の放出誘導中にもかかわらず，成熟の進行を一時的に抑え，放出のピークをずらす技術があり，成熟抑制技術や殻胞子放出抑制技術と呼ばれています。今回は，この処理中の胞子体の光合成活性の変化をモニタリングし，この技術の妥当性を評価しました。その結果，ノリ養殖の工程で実際に実施された3日間程度の放出抑制処理では，光化学系IIの実効量子収率は安定して推移することが示唆されました。
