About the Artwork
“‘Ano Lani; ‘Ano-Honua” by Laurie Sumiye.
The piece, titled after a traditional Hawaiian proverb meaning “A heavenly nature; an earthly nature” depicts Haumea, Hawaiian Earth Mother and Creation Goddess (ancestor to all indigenous Hawaiians) and modeled after Native Hawaiian scientist and SACNAS member Narrissa Spies. In her hands, she carries the Makalai tree, a tree of life. Behind Haumea is an active volcano (representing creation), verdant green mountains, and the Scorpio and Pleiades constellations (representing the ancestors). Below her, swims a red fish (representing nourishment), an iwa bird (representing travel and clear direction), and colorful hibiscus flowers (representing the diversity and beauty of Hawaiian people and native flora). As a whole, the artwork depicts the creation story — a tale of who we are and how we got here.
The upcoming conference is the largest multidisciplinary and multicultural STEM diversity event in the country. The three-day event focuses on empowering participants for their academic and professional STEM paths. Participants are inspired by scientific research and professional development sessions, motivational keynote speakers, an expo hall, and multicultural celebrations. “At 2019 SACNAS, you can shape your own STEM story inspired by your ancestors, mentors, and peers—nourished by diversity and fueled by passion for discovery,” notes the website about the event.

A study led by biologists at the University of Hawai‘i at Hilo documents the loss of bird song complexity and the convergence of the songs of three species of Hawaiian honeycreepers on the island of Kaua‘i.
The three species of Hawaiian honeycreepers, ‘akeke‘e (Loxops cauruleirostris), ‘anianiau (Magumma parvus), and Kaua‘i ‘amakihi (Chlorodrepanis stejnegeri), have seen rapid declines in their population numbers in the wild due most likely to avian malaria and habitat loss. The honeycreepers forage on insects and help to pollinate plants and disperse seeds in the forests of Kaua‘i, their natural habitat.
“We did this study specifically in Kaua‘i because it is in a real crisis mode,” says Kristina Paxton, an ecologist and post-doctoral researcher at UH Hilo, who was the lead author of the study. “Their populations are crashing and malaria is probably the largest driving factor of the declines. But we are not only losing the individuals, we are losing their songs. When you go into the forest in Kaua‘i it is now quieter, and that’s losing a part of what makes the Hawaiian forest what it is. The quietness of the forest is a sign that the forest is facing challenges.”
Paxton is affiliated with the LOHE lab, a bioacoustics laboratory at UH Hilo led by Patrick Hart, professor of biology, and Adam Pack, professor of psychology. The lab goes by the Hawaiian name LOHE, which means “to perceive with the ear” and is an acronym for Listening Observatory for Hawaiian Ecosystems.
In January 2019, Dr. Cam Muir, along with 20 students and faculty members from the University of Mississippi, conducted research on the fungal recruitment by tea plants and soil ecosystems. Fungi are well known to play key roles in plant growth and can benefit plants by acting as a both mutualists and decomposers. The diversity of fungi and the impact of their species diversity on soil ecosystems is still poorly understood.
This collaboration between UH Hilo and Ole Miss has led to the recent submission of a $3.5 M grant proposal: Establishing Foundations for Ecosystem Steering. The proposal team is composed of faculty from University of Surrey (UK), Waseda University (Japan), Georgia Institute of Technology (USA), Earth-Life Science (Japan), University of Mississippi, and University f Hawai`I at Hilo (USA).

Matthew Knope, assistant professor of biology, received the Frances Davis award for Excellence in Teaching. Assistant Prof. Knope joined UH Hilo in fall 2017 and quickly became known for putting teaching and his students as his highest priorities. Colleagues praise him for demonstrating his commitment and strong ability to integrate research and teaching and to directly involve students in his research. He is considered a natural and effective teacher and a rising star in the field of ecology and evolution.
The gift from Hawaii Forest & Trail will support research and technologies to reduce mosquito populations that spread avian disease in Hawai‘i.
A local tour company with a strong conservation mission has donated $25,000 to the biology department at the University of Hawai‘i at Hilo. The gift from Hawaii Forest & Trail will support research and technologies to reduce mosquito populations that spread avian disease in Hawai‘i.
“It’s our hope that through this donation, important research work will continue to make strides in protecting Hawaiian forest birds, including our much-loved ‘i‘iwi,” says Rob Pacheco, founder and president of the tour company.
The primary reason for the continued decline of native honeycreepers is mosquito-transmitted diseases such as avian malaria and avian pox. Climate change is exacerbating the problem, and mosquitoes are beginning to move up in elevation to the last disease-free habitats on all Hawai‘i islands.
Research shows mosquito suppression can be achieved by introducing different strains of Wolbachia bacteria into mosquitoes, which drops reproduction rates. Wolbachia male-based insect control programs have been highly successful for reducing local mosquito populations around the world.
“The ultimate goal is to be able to release male mosquitoes with a different Wolbachia strain into the wild to mate with wild females, to suppress mosquito populations,” says Jolene Sutton, assistant professor of biology and top researcher into native avian disease via mosquitoes. None of the mosquitoes here are native to Hawai‘i. If we can reduce or even eliminate mosquito populations in Hawai‘i, we have a good change of saving many iconic bird species. Our research focuses on evaluating and developing novel strategies for mosquito control, including Wolbachia-based strategies and genetic ones. We want to ensure that new technologies are safe and effective.”
She adds, “This donation will go a long way to help further this work. We are very grateful to have this kind of local interest and support.”
The Society for Ecological Restoration recently presented the Bradshaw Medal to two outstanding papers published in its peer-reviewed journal, Restoration Ecology. Named for famed British ecologist and restoration pioneer Tony Bradshaw, the award honors scientific papers that advance the field of restoration ecology in a significant way. Susan Cordell, Rebecca Ostertag, Jené Michaud, and Laura Warman published “Quandaries of a decade‐long restoration experiment trying to reduce invasive species: beat them, join them, give up, or start over?” Their study investigated the most effective way to reforest native species in Hawai’i to recover biodiversity. Ostertag is a member of the Biology department and Michaud is a member of the Geology department at UH Hilo, while Cordell and Warman are affiliated with the USDA Forest Service Institute of Pacific Islands Forestry.

Assistant Professor Li Tao has received an INBRE IV Junior Investigators (JIs) Award for his project, “Structural and Functional Analysis of Centralspindlin”. The INBRE IV JIs Award will provide substantial funding for up to 3 years at $100,000/year in direct costs. The Tao’s lab will center its research on the molecular mechanism through which centralspindlin regulates cytokinesis. Abnormal cell division (mitosis) causes cancer. Understanding the mechanism of cell division and its regulation has thus become a key to finding cures for cancer. Cytokinesis is the last gate to control cell division. Cytokinesis is dominated by a motor complex, centralspindlin. However, little is known of the structure and function of centralspindlin. This project will address a significant knowledge gap on the regulation of cytokinesis. It will also provide clues for the development of new anti-cancer therapies.
