How bacteria induce settling and transformation of marine larvae investigated

A close-up image of the tubeworm Hydroides elegans with its feather-like tentacles extended from its tube. The tentacles both collect microscopic food particles from the water and serve as the place for gas exchange for the worm, passing carbon dioxide from the worm and gaining dissolved oxygen from the water.

For more than 100 years, marine biologists have sought an understanding of how the minute larvae of marine invertebrate animals—cast out into the vast ocean—find and settle in the right ecological settings for survival, growth and reproduction. A grant, totaling more than $870,000, from the Gordon and Betty Moore Foundation to the University of Hawaiʻi will support research to understand the ...

Researchers at the University of Hawaiʻi at Mānoa developed an array of highly innovative experiments to allow scientists to safely test first-aid measures used for box jellyfish stings—from folk tales, like urine, to state-of-the-art technologies developed for the military. The power of this new array approach, published this week in the journal Toxins, is in its ability to rigorously assess the ...

The small but charismatic Hawaiian bobtail squid is known for its predator-fooling light organ. To survive, the nocturnal cephalopod depends on a mutually beneficial relationship with the luminescent bacterium, Vibrio fischeri, which gives it the ability to mimic moonlight on the surface of the ocean, and deceive monk seals and other predators that would happily make a meal of the ...

Novel tsunami detection network uses navigation systems on commercial ships

UH Mānoa researchers have equipped 10 Matson and Maersk Line ships with real-time geodetic GPS systems and satellite communications to create a network of low-cost tsunami sensors.

Accurate and rapid detection and assessment of tsunamis in the open ocean is critical for predicting how they will impact distant coastlines, enabling appropriate mitigation efforts. Scientists from the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST) are using commercial ships operating in the North Pacific to construct a network of low-cost tsunami sensors ...

Undergrad helps discover new bacterium on way to marine biology degree

Terasakiispira papahanaumokuakeensis, spiral-shaped bacterium grown from a pond on the Pearl and Hermes Atoll in the Northwestern Hawaiian Islands.

A UH Mānoa undergraduate who conducted a research project on her way to earning a bachelor of science degree in 2014 in marine biology was instrumental in the discovery of a spiral-shaped bacterium that is the only known representative of a new genus and species. Vanessa K. Zepeda, 30, is the lead author of a paper published in the current ...
