Best poster presentation award in the 8th Asian-Pacific Phycological Forum


A PhD. student of the MB lab, Mr. Jumpei Kozono was awarded the best poster presentation award in the 8th Asian-Pacific Phycological Forum (APPF) that was held in Kuala Lumpur, Malaysia in October 2017. APPF is an international conference of Phycology in the Asian-Pacific Region that has been held every three years, and more than 300 participants were attended.
Based on the field and laboratory experiments, he presented the ecophysiological study of an endangered freshwater red alga, Thorea okadae from Japan, and determined the optimum irradiance and temperature environments on the photosynthetic performance. This knowledge is expected to contribute the conservation of the optimum habitat for this species.

ひらめきときめきサイエンスを開催しました


日本学術振興会ひらめき☆ときめきサイエンスに採択された公開講座「本物の海藻を見てさわって食べて「海の森」図鑑をつくろう」が7月23日(日)と30日(日)の2日間,鹿児島大学水産学部で開催されました。抽選で選ばれた児童30名が参加しました。
 23日は,海苔やワカメ,コンブなどの食べられる海藻を観察すると共に,テングサから寒天を抽出し,シロップなどで味付けをしてゼリーをつくって試食しました。コンビニなどで売られているゼリーのもとが身近に生えている海藻であることを知り,食べ物の生きているときの姿を学びました。午後は鹿児島大学の調査研究で採取された約40種の海藻を用い,押し葉を作成しました。中には,海藻を使った絵画作品をつくる児童もいました。海藻押し葉は一週間かけて乾燥させました。

種子島沖の調査航海


鹿児島大学水産学部附属練習船南星丸に乗船し,種子島の沖合で調査をおこないました。海藻類の調査は海岸線に近い場所が一般的ですが,南西諸島の周辺は透明度が高く,水深40m付近でも海藻が多く生育しています。調査では,水深40m付近の海藻をドレッジで採集したり,採泥器で微細藻類を採取しました。また,CTDを使って水中の光量と温度を測定しました。毎年実施している本調査から,以下の論文が最近公表されています。

海苔網冷蔵(冷凍)処理中のアマノリ配偶体の光合成活性と耐性


海苔養殖では育苗後に海苔網の約半分を陸にあげて乾燥させ,アマノリの芽がついたまま凍結保存しています。この冷凍網は一ヶ月ほど冷凍保存され,1月以降の養殖に用いられていますが,乾燥と冷凍処理における藻体の生理状態(光合成活性)は長らく不明でした。本研究では,乾燥・凍結中の生理状態の変化と回復の過程をパルス変調クロロフィル蛍光測定を用いて初めて明らかにしました。

Marine Botany Lab welcomes a new faculty member



Marine Botany Lab is proud to announce that Dr. Hikaru Endo has joined the MBL in Kagoshima University as the new full-time Assistant Professor. He studied marine algae and benthic biological organisms at the undergraduate and postgraduate schools of Agricultural Science, Tohoku University, and received the BSc, MSc, and PhD degrees. His research at MBL focuses on to elucidating that how environments influence to the ecophysiology and community structure of marine macroalgae.
MBL is very excited that he brings his expertise to the lab.
