Dr. Stan Nakanishi publishes Nature Protocols paper with an international team describing methods for sensory and motor experiments using decerebrate adult mice
Dr. Nakanishi and colleagues developed a collection of specialized techniques to record from live mice in order to study how the nervous system encodes sensory information, processes those signals, and produces movements in living organism, all without anesthetic complications. Briefly, this set of protocols describes the animal surgery techniques that can be used to study sensory-motor integration in live, adult mice whose brain is removed.
Using this preparation, we can better understand how sensory information is collected, integrated, how we produce complex reflex patterns. We can study cardiovascular and respiratory functions, and learn more about the spinal circuits that coordinate the muscle activity for movements and walking.

Dr. Jolene Sutton and colleagues make the front page of the Hawai'i Tribune-Herald for their mosquito research
"To protect Hawaiʻi’s unique, imperiled native birds, researchers from the University of Hawaiʻi at Mānoa and UH Hilo are teaming up with the Department of Land and Natural Resources (DLNR) and the U.S. Fish and Wildlife Service to adapt a ‘birth control’ method used across the U.S. mainland to control mosquitoes. The scientists are taking the first steps to adapt a safe, targeted and efficient mosquito control method known as Incompatible Insect Technique to reduce the population of the disease-carrying mosquitoes that harm native birds in Hawaiʻi."

UHH Biology Graduate Ann Tanimoto and colleagues publish paper on the vocal repertoire of the Hawaiian crow
For most avian species, social behavior is critically important for survival and reproductive success.Many social behaviors in birds are culturally transmitted, and as bird populations decline across the globe, important elements of these behaviors may be lost. The Hawaiian crow or'alalā,Corvus hawaiiensis, is a socially complex avian species that is currently extinct in the wild.
As in other oscine passerines, vocalizations in the'alalāmay be culturally transmitted.We compared the vocal repertoire of three of the last four wild'alalāpairs from the early 1990s to three current captive pairs at the Keauhou Bird Conservation Center in Volcano, Hawai'i to determine how acoustic behavior has been affected by changes in their social and physical environment.

Dr. Stan Nakanishi publishes PNAS paper on alphaB-crystallin protein and its unique properties of regenerating neurons
Nerves send signals throughout our brain, spinal cord, and body. Some nerves send sensory signals to the brain; other nerves send signals that tell our muscles to contract and produce movements. If nerves in the body are damaged, some of the nerves regrow but the recovery is usually incomplete, leading to problems with sensory or movement functions and even neuropathic pain.
The goal of this project was to learn more about a molecule that is important for the regrowth of damaged nerves. The molecule is called alphaB-crystallin (aBC), and this molecule helps nerves regrow after an injury. We found that aBC affects the recovery and regrowth of sensory and motor nerves, and that we can improve the recovery process by adding extra aBC after a nerve injury.

UH Hilo Students Sequence Marine Bacterium, Pseudoalteromonas luteoviolacea, a Symbiont of the Hawaiian Marine Sponge Iotrochota protea
UH Hilo Students, Martin Helmkampf, Kehau Hagiwara, Courtney Ip, Brandi Antonio, Ellie Armstrong, and Wesley Ulloa collaborated with Francis Saskia-Kawada of UH Manoa and Jonathan Awaya of the UH Hilo Biology Department to publish their findings on the Hawaiian marine sponge symbiont, Pseudoalteromonas luteoviolacea.
This study focuses on the biosynthetic pathways of the bacterium and may help to further our understandings of the ecological interactions between the native Hawaiian sponge and its symbiotic microbe.
Dr. Jon Awaya also noted that this research is exciting because it was completely conducted at UH Hilo and by UH students.

UH Hilo integral to research that forecasts future ocean crisis
On the heels of President Barack Obama’s announcement to quadruple the size of the Papahanaumokuakea Marine National Monument in the Northwestern Hawaiian Islands, an assistant professor of biology at the University of Hawaiʻi at Hilo has co-authored research on the emerging biodiversity crisis in the world’s oceans. The publication, entitled “Ecological selectivity of the emerging mass extinction in the oceans,” will be included in the September 16 issue of the journal Science.
Matthew Knope collaborated with lead-author Jonathan Payne and Noel Heim of Stanford University, Andrew Bush of the University of Connecticut, and Doug McCauley of the University of California, Santa Barbara.
The study compared the ecological traits and extinction threat level of animals in oceans today to the ancient past and concluded that future ecological disruption has the potential to be much greater than with past mass extinctions.
“Even under the most optimistic business-as-usual scenario, vertebrate extinctions could far exceed those of any other time since the end-Cretaceous mass extinction 66 million years ago when the planet was struck by a meteorite leading to the extinction of the dinosaurs,” Knope said.

Please welcome our newest Biology Faculty member, Dr. Matt Knope
Matthew Knope is a new Assistant Professor of Biology at UH Hilo. He received a Bachelors degree in Marine Biology with honors from the University of California, Santa Cruz (1999), a Masters degree in Marine Biology from San Francisco State University (2004), and a Ph.D. in Biology from Stanford University (2012). Also at Stanford, he was a Howard Hughes Medical Institute Postdoctoral Teaching Fellow in the Dept. of Biology (2012), a Postdoctoral Research Fellow in the Dept. of Geological and Environmental Sciences (2013-2014), and a Lecturer in the Dept. of Biology (2014-2015). Before joining the faculty at UH Hilo, he was most recently an Assistant Professor of Ecology and Field Biology at the University of San Francisco (2015-2016). He is broadly interested in almost all aspects of biology, but his primary research topics are related to the evolutionary ecology of both marine and terrestrial organisms, in Hawaii and elsewhere. In addition, he is strongly motivated to develop and share innovative teaching methods in the sciences.
