Please
take a look at our new article on two newly discovered species of the
genus Solieria from offshore Tanegashima Island. It was published on May
12, 2025, in Phycologia, the official journal of the International Phycological Society.

In recent years, we have focused on species diversity and environmental adaptations in Mesophotic Coral Ecosystems (MCEs—ecosystems found at depths greater than 30 m) around offshore Tanegashima Island, and have published a series of related articles. The species name Solieria yoshidae was dedicated to the late Dr. Tadao Yoshida (1933–2024), Professor Emeritus of Hokkaido University, who was a specialist in the taxonomy of Solieria.
As part of a collaboration between our lab and the algal lab at Kobe University, Professor Terada and an MSc student participated in field surveys for the nationwide long-term monitoring of algal communities, which was conducted by Kobe University. During two surveys—at Awajishima Island and Takeno—dense communities of Ecklonia and Sargassum spp. were confirmed.

We had an MB Laboratory seminar at the beginning of the spring semester. As it was the first seminar of the term, Dr. Terada and Endo presented their recent research topics. The seminar will be held every two weeks until September, during which students will present their progress reports and introduce recently published articles.
Professor Ryuta Terada of the Marine Botany Lab attended the Asian Pacific Phycological Association (APPA) Regional Meeting in Rongcheng, Shandong Province, China, from April 21 to 23, 2025. During the meeting, studies on kelps and other valuable species were presented, and constructive discussions took place. Rongcheng City is one of China’s most productive regions for Saccharina japonica cultivation.
The next APPA regional meeting will be held in Thailand in 2026.
Please take a look at a newly published article on the introduction of the Pacific oyster, as well as other species that were transported with it to various regions. The article is now available in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

As the opening event of the special exhibition The World of Marine Algae, a workshop on making marine algae herbarium specimens was held at Kagoshima City Aquarium in Kagoshima. Twelve elementary and junior high school students attended. The students created herbarium specimens of twenty-four species of marine algae collected from various locations in Kagoshima Prefecture.
Please take a look at our latest article on the DNA-based floristic survey of red algae (Rhodophyta) in the mesophotic coral ecosystems (MCEs) offshore of Tanegashima Island, Japan.
Spring has come!
As spring arrives, the time of the lowest daily low tide shifts from nighttime to daytime, making intertidal algae surveys easier to conduct on the rocky shore. Yesterday, we conducted a survey at Nishikata Beach, Satsuma-Sendai City, which faces the East China Sea. Notably, Pyropia suborbiculata, Grateloupia asiatica, and Gloiopeltis furcata were abundant on the intertidal rocks.
