Microbes dominate Earth. They have been discovered wherever anyone has looked for them. Every animal and plant relies on interactions with the microbial world for health. Given that nearly every habitat and organism hosts a diverse constellation of microorganisms—its “microbiome”—understanding that complex system could transform ideas about the natural world and launch innovations in agriculture, energy, health, the environment and ...

For many animals, pheromones, which are chemical cues used for communication, guide important decisions such as whom to mate and whom to fight. New research from scientists at the University of Hawaiʻi at Mānoa’s Pacific Biosciences Research Center (PBRC) identified a single gene in fruit flies (Drosophila) that controls male pheromone production, male fertility, and, surprisingly, the fertility of rival ...

Hawaiʻi has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawaiʻi’s formerly spectacularly diverse and unique biota. A team of researchers, ...

New research, published today in eLife from a researcher at the Pacific Biosciences Research Center (PBRC), a newly integrated research unit of the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa, identified the neural circuit in the brain of the fruit fly (Drosophila melanogaster) that is responsible for detecting a taste pheromone, ...

Where have all the codfish gone?


The mega-decline in cod and other fisheries across the North Atlantic Ocean threatens the livelihood of fishermen and communities in New England and Atlantic Canada.  One suspect in the disappearance of cod and other groundfish is the food source for their young: a planktonic copepod crustacean, no larger than a grain of rice.  Recent changes in local copepod populations have ...

Long-term study links box jellyfish abundance, environmental variability

Box jellyfish (Alatina moseri)

You can almost set your watch to it. A familiar sight to beachgoers, the box jellyfish Alatina moseri is known for showing up in big numbers on Waikīkī Beach 8 to 12 days after each full moon. Continuing a pioneering jellyfish beach count effort initiated in the 1980s by Honolulu lifeguard Landy Blair, researchers at the University of Hawai‘i at Mānoa have ...
