Using cryogenic electron microscopy, a research team from the Research Center for Artificial Photosynthesis (ReCAP) at Osaka Metropolitan University has revealed, for the first time, the structures and binding environments of pigments bound to a protein called a photosynthetic antenna of the marine green macroalga Codium fragile. The team’s results extend our knowledge about the molecular mechanism by which blue-green light—the only light available in deep seawater—is efficiently utilized for photosynthesis.

An international team of researchers respond to criticisms on previous work that demonstrated Mirror Self-Recognition (MSR) in the cleaner fish Labroides dimidiatus, by 1) successfully repeating the mark test with a larger sample size, 2) showing the MSR behaviour to be the visual result of the mark not a physical response to it, and 3) showing that MSR-trained fish do not show aggression to spatially varied mirror images of themselves. Additionally, they further demonstrate potential self-awareness in L. dimidiatus by showing that they do not demonstrate MSR behaviour when visually presented with the mark on other fish and solidify the importance of ecologically relevant marks presented in previous work by showing MSR behaviour of L. dimidiatus with brown marks, meant to resemble a main food source of the fish, as opposed to no such behaviour in fish with green or blue marks.

Coral reefs, comprising some of the most diverse and delicate ecosystems under water, are under immense stress. From global warming to pollution to pathogens, many of the reef-building coral species are listed as threatened or endangered. But, according to researchers in Japan, the corals may have an unlikely ally: bacteria.

Social vulnerabilities of coastal communities and their reliance on blue carbon ecosystem services may be improved by addressing three major factors, according to a study led by Hokkaido University researchers.

Scientists from Hokkaido University have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea – regions where species richness, community stability and climate stability are high.

Deep sea animals face greater risks compared to those nearer the surface as they become less able to maintain their preferred thermal habitats with climate change.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.

Recognizing species is important for understanding regional biodiversity and for environmental conservation. However, taxonomic identity is sometimes obscure even with the organisms that are closest to human life.

Scientist's understanding of this microscopic invertebrate has grown after the second discovery of Loricifera near Japan.

Scientists could gain insight into atypical sex development in vertebrates, including humans, by studying how nutrition affects sex changes in fish larvae.

During the early summer, corals simultaneously release tiny balls composed of sperm and eggs, known as bundles, that float to the ocean surface. Here the bundles open, allowing the sperm to fertilize the eggs where they eventually settle on the seafloor and become new coral on the reef.

Global simulations suggest plankton and fish species are showing resilience to climate change by going deeper underwater or moving to higher latitudes.

A new beaked whale species Berardius minimus, which has been long postulated by local whalers in Hokkaido, Japan, has been confirmed.

A group of biologists from Hong Kong Baptist University (HKBU) have discovered a new fireworm species in Hong Kong waters and named it Chloeia bimaculata. It is the fourth named species to be added to the fireworm genus Chloeia during the last century. The team also identified Chloeia parva as the fireworm species that caused the outbreak in Hong Kong last year. The discovery shows how little people know about the biodiversity of this group of animals.

In the longest running study of its kind, researchers found sea urchin populations were strongly affected by human-driven environmental changes.
Jorge García Molinos is an aquatic ecologist broadly interested in global change ecology and macroecology.
Associate Professor Sitti Raehanah Muhamad Shaleh is the director of Borneo Marine Research Institute at Universiti Malaysia Sabah.
Professor Qiu Jianwen currently works at the Department of Biology, Hong Kong Baptist University. He is interested in ecology and adaptation of apple snails, biodiversity and systematics of polychaetes, stress responses in shallow-water corals, and deep-sea biology. His research involves the use of various molecular tools including transcriptomics, proteomics and genomics.
Giants in history
The techniques that make industrial pearl culturing possible were developed over a century ago at the Misaki Marine Biological Station in Japan. The station’s first director, Professor Kakichi Mitsukuri, emphasized to Kokichi Mikimoto in 1890 that stimulating pearl sac formation was important for pearl growth, and they went on to successfully develop methods for culturing pearls.
Osamu Shimomura (27 August 1928 – 19 October 2018) was a Japanese organic chemist and marine biologist who dedicated his career to understanding how organisms emitted light.
Edgardo Dizon Gomez (7 November 1938 – 1 December 2019) was a Filipino marine biologist who recognized the need to protect marine resources, especially coral reefs, in the Philippines.
