Organism responsible for paralytic shellfish poisoning could affect fisheries

New research published in Scientific Reports by scientists at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology suggests that ingestion of the toxic dinoflagellate Alexandrium fundyense changes the energy balance and reproductive potential of a particular copepod, a small crustacean, in the North Atlantic that is key food source for young fishes, including many commercially important species. Alexandrium fundyense is a photosynthetic …

Corals and humans share genes

University of Hawaiʻi at Mānoa scientists at the John A. Burns School of Medicine and the Hawaiʻi Institute of Marine Biology (HIMB) have published new research showing that corals share many of the genes humans possess, especially those that can sense temperature and acidity, both of which are important to keeping both coral and humans healthy. The findings, published in the journal eLife, are the …

Scientists discover world’s largest known sponge in Papahānaumokuākea MNM

Researchers in the summer of 2015 were surveying an ocean ridge in a marine conservation area off the shores of the Northwestern Hawaiian Islands and amid ordinary ocean floor fare — a bit of coral, some volcanic rock — they came across something surprising: they discovered what they say is the world’s largest known sponge. Roughly the size of a …

Fishing networks study may save sharks

Tuna fishers who network with their competition may be able to stop thousands of sharks a year from being accidentally captured and killed in the Pacific Ocean. Researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University and the University of Hawaiʻi at Mānoa found if fishers communicated more with their rivals, it could lead …
