A new species of bacteria has been discovered off the coast of Oʻahu, shedding light on how unseen microbial life connects �鶹��ý’s land and sea ecosystems.

Researchers at the University of �鶹��ý at Mānoa identified Caulobacter inopinatus, a previously unknown species of bacteria found in seawater collected near a beach on Oʻahu’s south shore. The finding——was unexpected because all other known species in the Caulobacter genus (a scientific group that includes closely related species) are from freshwater or soil environments, not the ocean.

The discovery, made during a UH Mānoa undergraduate marine microbiology class, began as a routine demonstration on how to grow bacteria from seawater samples. When one colony growing on a Petri dish looked different from all the other colonies, further testing confirmed it was something entirely new.

From land to sea

Scientists found that C. inopinatus cannot survive in salt concentrations typical of seawater, despite being isolated from it. This paradox led researchers to investigate how it ended up in the ocean. They determined it was likely transported from land by submarine groundwater discharge—the natural movement of fresh groundwater through the seabed into the sea. These discharges are known to carry nutrients and pollutants into nearshore waters; in this case, they may also move land-based microorganisms. Microbial exchanges are important because bacteria play critical roles in nutrient cycling, water quality and coastal ecosystem health.

“Understanding how microbes move between land and sea helps scientists track the flow of nutrients and contaminants that can affect coastal water quality, fisheries and coral reef health—issues that directly impact �鶹��ý’s communities and economy,” said study co-author and UH Mānoa Professor Stuart Donachie. “Discoveries like C. inopinatus help us better trace how land-based activities and natural processes influence marine environments at a microscopic level.”

The species name, inopinatus, comes from the Latin word for “unexpected,” reflecting both the chance nature of its discovery and its surprising characteristics.

Collaborative work

The research was part of ongoing microbial diversity studies led by Donachie. Undergraduate researchers Austin Dubord and Mia Sadones contributed to the project through UH ��ā�ԴDz�’s , which supports student-led research and creative work. Collaborators included UH Mānoa faculty Michael Norris and Jennifer Saito, graduate students Chiyoko Onouye and Thi Hai Au La, and University of Mississippi Assistant Professor and UH Mānoa PhD graduate Rebecca Prescott.

The study is dedicated to the late UH Mānoa Earth Sciences Professor Craig Glenn (1954–2024), whose pioneering research on submarine groundwater discharge in �鶹��ý helped illuminate how freshwater and seawater interact along island coastlines, and to former UH undergraduate student Justin Bukunt (1983–2011), whose early research on groundwater discharge at Kawaikui Beach Park informed this discovery. Their contributions continue to inspire new generations of scientists exploring �鶹��ý’s unique coastal environments.

The University of �鶹��ý at ��ā�ԴDz�’s and the (PEPP) in UH ��ā�ԴDz�’s joined forces with Honolulu Beerworks to host “Sips for Seedlings,” an outreach and fundraising event on October 11, at Honolulu Beerworks’ new Kalihi taproom.

The event, which drew more than 200 people, spotlighted efforts to protect �鶹��ý’s most endangered native plants, while inviting the community to learn more through hands-on engagement and collaboration.

Attendees enjoyed the re-release of Hāhā-Loha, a limited-edition grape sour ale inspired by the conservation of rare Hawaiian plants. The beer was originally created through a partnership among the three organizations to spark public interest in native plant protection. A portion of proceeds from beer sales, as well as contributions from Shaka Mobile Bar and Local Boiz Mixed Tea, supported ongoing conservation and education work at Lyon Arboretum and PEPP.

Throughout the day, Lyon Arboretum staff shared educational materials, photographs and displays highlighting the islands’ threatened flora. Visitors also had the opportunity to purchase plants grown by the arboretum and participate in keiki-friendly activities designed to foster awareness of native ecosystems.

“Our goal is to make conservation approachable and engaging for everyone,” said Lyon Arboretum Education Manager Raedelle Van Fossen. “Events like ‘Sips for Seedlings’ remind our community that protecting �鶹��ý’s native plants isn’t just about science—it’s about connection, culture and ensuring these species have a future in our islands.”

The Hāhā-Loha label featured artwork by UH Hilo alumna and former Lyon Arboretum summer intern Saxony Charlot, whose work celebrates �鶹��ý’s biodiversity and the people dedicated to preserving it.

On islands, many plants rely on animals such as birds, bats and reptiles to disperse their seeds and help them grow in new places. When native animals go extinct, this naturally reduces seed dispersal. However, a new global study, , has discovered that the impact of introduced, invasive animal species on how plant seeds are dispersed across island ecosystems is even greater than the impact of native animal extinctions.

The study analyzed data from 120 islands across 22 archipelagos, examining how extant native, extinct native, and introduced vertebrate frugivores—animals that eat fruit and disperse seeds—affect plant reproduction. The findings of how significantly invasives are altering seed dispersal across islands highlight the severity of the new challenges for plant reproduction and ecosystem health. The study is co-authored by Donald Drake, professor in the UH Mānoa in the and interim director of .

“Understanding how introduced species reshape ecological interactions is crucial for planning effective conservation strategies,” Drake said. “In �鶹��ý, where native ecosystems are particularly vulnerable, these findings underscore the need for proactive management to preserve our unique biodiversity.”

The study reported that non-native mammals, especially omnivorous mammals, such as pigs and rats, have often replaced native frugivorous birds, bats and tortoises. These replacements frequently have different physical traits, such as smaller or larger gape sizes (the width of an animal’s mouth or bill), which affects the size of seeds they can carry. And they sometimes destroy seeds rather than dispersing them intact. As a result, some native plants may no longer be effectively dispersed, threatening their regeneration and long-term survival.

Researchers also found that species introductions typically outnumbered extinctions both in terms of species numbers (faunas average 44% introduced species versus 23% extinct) and in the number of islands impacted (92% versus 76%). This suggests that human activities, including accidental and deliberate introductions of animals, are adding to extinctions in driving widespread changes to island ecosystems.

�鶹��ý’s forests in danger

In �鶹��ý, native forests originally relied entirely on native birds to spread seeds of plants such as lama, hōʻawa and olopua. When introduced animals replace these natural dispersers, the regeneration of native forests can slow or stall, affecting not only biodiversity but also watershed health and cultural practices tied to native plants. The research underscores the importance of managing invasive species and protecting remaining native frugivores to maintain the islands’ unique ecosystems.

“Many studies focus on individual species or single islands, but this research shows that introductions can fundamentally alter ecological interactions on a global scale,” Drake said. “For �鶹��ý, these insights are vital: we need to control introduced animals, protect the remaining native frugivores and restore disrupted seed-dispersal networks to safeguard our forests and native plants.”

The University of �鶹��ý named Ivan Hartison as the 2025 recipient of the President’s Award for Excellence in Building and Grounds Maintenance.

Hartison was honored for his vital work at the Isabella Aiona Abbott Life Sciences Building at UH ����ԴDz�. He plays an important role in high-level research spaces, including BSL-2 labs and endangered species insectaries, where he helps ensure safety, sanitation and the protection of �鶹��ý’s natural resources.

Beyond his daily duties, Hartison is known for going above and beyond, whether helping students recover endangered Hawaiian flies, lending a hand with heavy lifting or stepping in to support colleagues.

Through his commitment to his job at UH ����ԴDz�, Hartison earned the respect from both peers and students, embodying the spirit of teamwork and service at the University of �鶹��ý.

Established in 1986, the President’s Award for Excellence in Building and Grounds Maintenance recognizes a UH system employee who exemplifies dedication and excellence in supporting campus facilities.

A new deep-sea coral species in the tropical western Pacific that resembles a highly recognizable character from Star Wars has been discovered and named by a team of researchers including an expert from the University of �鶹��ý.

The coral, named Iridogorgia chewbacca, is known for its long, flexible branches and shiny surface. The species earned its nickname because the coral’s “hairy” looking branches and upright, lone-standing appearance reminded researchers of Chewbacca, the furry character from the Star Wars films.

The species belongs to the genus Iridogorgia, a group of deep-sea corals with long, spiraling structures. The new coral was first seen in waters off Molokaʻi in 2006 and later near the Mariana Trench in 2016. The Molokaʻi specimen measured about 4 feet tall, while the Mariana Trench sample was about 20 inches. The branches are flexible and can grow up to 15 inches long.

Les Watling, professor emeritus in UH ��ā�ԴDz�’s and co-author of the , recognized the coral while reviewing research from colleagues in China. His earlier work in �鶹��ý waters and collaborations with NOAA expeditions helped confirm that it was a new species.

“Seeing this coral for the first time was unforgettable,” Watling said. “Its long, flexible branches and shape immediately reminded me of Chewbacca. Even after years of deep-sea work, discoveries like this still make me stop and take notice.”

The study used both physical characteristics and genetic analysis to describe I. chewbacca and another new species, Iridogorgia curva. It also documented other known species in the western Pacific. Researchers found the region has a high diversity of Iridogorgia, with 10 species recorded in tropical western Pacific waters.

Thousands working together

Each coral colony is made up of thousands of tiny polyps, which work together to form the larger structure. Despite its large size and striking appearance, I. chewbacca usually occurs alone, scattered across deep-sea rocky bottoms.

Watling’s work highlights UH’s contributions to deep-sea research and shows the value of international collaboration in discovering and documenting new marine species. The discovery adds to scientists’ understanding of the biodiversity hidden in the deep ocean and demonstrates that even long-studied regions like the Pacific still hold surprises.

Growing up in Chandler, Arizona, thousands of miles from the nearest coastline, University of �鶹��ý at Mānoa major and undergraduate student Landon Schumaker never imagined his future would take him to the farthest reaches of the deep sea. But this summer, Schumaker conducted research in Perth, Australia, with the support of the , a funding opportunity administered by the UH Mānoa (UROP) and the .

From June through August, Schumaker worked with the Minderoo-University of Western Australia Deep-Sea Research Centre to study the Nova Canton Trough, a hadal region more than 6,000 meters deep. This area had never been studied at such scale and depth until recently.

Schumaker said that last year scientists conducted an expedition to the Nova Canton Trough and deployed cameras to assess deep-sea biodiversity between 2,471 and 7,983 meters deep. He contributed to meticulous work on this footage, including taxonomic identifications, statistical analyses and visualizations.

“The deep sea fascinates me because it feels like an entirely different world,” Schumaker said. “It’s a world that is perceived to be so far away, yet in reality, is on our planet and right beneath our surface waters. There are vast knowledge gaps, and every expedition brings the possibility of discovering something new.”

Schumaker’s work was complemented by monthly virtual check-ins with his UH Mānoa mentor, Professor Jeff Drazen in the , who has guided him for more than a year.

“Landon was pretty familiar with the deep ocean when he departed for Australia, and he had already analyzed deep-sea videos. But in Australia he really dug into big datasets, and he dramatically increased his ability to use statistical modeling to explore research results,” Drazen said. “I’m really impressed that he analyzed the data and has a draft of a peer reviewed paper. This was a stellar opportunity for Landon and he really capitalized on it.”

Looking ahead, the results from the Nova Canton Trough study are expected to lead to at least two scientific publications, with Schumaker as a co-author, and potentially lead author. Long-term, he hopes to pursue a PhD in biological oceanography and dedicate his career to exploring and protecting the deep sea.

More on the Tyler Fellowship

“The Tyler Fellowship provided me with the financial support I needed to travel, live abroad for an extended period and gave me the opportunity to learn about so many different projects going on around the world,” Schumaker said. “This fellowship meant a lot to me, as it was something I put a lot of effort into between developing a proposal and a project plan, and then being entrusted with this award. Receiving it was both rewarding and humbling.”

From tracking invasive marine species, to exploring vegetation recovery on degraded, uninhabited islands, to studying tiny beetles threatening mangroves, eight University of �鶹��ý at Mānoa undergraduates spent two months this summer in the Galápagos Islands. Funded by a grant from the National Science Foundation with additional support from UH Mānoa, and guided by research mentors from UH Mānoa and the Charles Darwin Foundation, the students conducted hands-on research on invasive species that connected them to ʻāina (land/sea), kānaka (people) and mālama ʻāina (stewardship).

The experience built on a preparatory spring course (NREM 491), where students learned the foundations of island invasion biology and developed their own research proposals.

Monitoring invasive species

Cienna Kahrobaie, a major, studied invasive marine species at boat docks around Puerto Ayora on Santa Cruz Island. Using settlement plates (small experimental surfaces for marine organisms to grow on) deployed for two months, she compared species richness, percent cover, and community composition at docks experiencing differential boat traffic, and learned valuable identification techniques from experts at the Charles Darwin Foundation and Smithsonian Tropical Research Institute in Panama.

“Settlement plates allow scientists to get a glimpse of what is growing in marine communities around boat docks, so if we employ them at sites with specific maritime traffic patterns, we can more quickly detect invasive species of concern,” Kahrobaie said. “This would allow conservationists to respond quicker to these marine invasions and prevent their establishment.”

While conducting research, she found a moment of discovery while resting in a tidepool. By staying still, she observed fish, hermit crabs and even an octopus up close, learning that sometimes slowing down revealed more than trying to see it all at once.

Studying connections between islands

Riley Herron, a major, conducted research on Santa Fé Island, a remote, uninhabited Galápagos island recovering from heavy feral goat degradation and resulting ecological damage. She studied how the island’s microtopography affects microclimates critical for woody plant seedling establishment, setting up large plots to measure environmental conditions and seedling presence for the island’s three dominant woody species. Through her research, Herron found connections between the Galápagos and �鶹��ý.

“I hope my research helps highlight the interconnectedness of our ecosystems,” Herron said. “There are so many large-scale processes that shape what happens on the micro level, and as our climate continues to change, understanding those small-scale interactions becomes more important than ever. As island ecosystems are isolated, limited in resources and filled with endemism, they are the first to be impacted, emphasizing how important island conservation is globally.”

Tiny threatening beetles

Lana Mitchell, a major, studied how an invasive mangrove bark beetle affects native red mangrove seedlings, testing whether fertilizer could offset beetle damage. The project challenged her to conduct independent research while navigating new skills, from kayaking to communicating in Spanish, all while deepening her passion for conservation.

“I hope that this can aid scientists in measuring how much of a difference in survival and growth a propagule (a young mangrove seedling) can undergo with and without beetle infestations,” Mitchell said. “This research could help to determine the overall survival of native species in exposure to invasives, giving scientists a window of time in which to provide native species with resources to better sustain their growth and longevity in island ecosystems.”

Mitchell was struck by how comfortable Galápagos wildlife are around humans, spotting sea lions resting just steps away during her research. According to Mitchell, the experiences reinforced the local community’s dedication to conservation and strengthened her connection to the islands’ unique ecosystems.

“This immersive summer research program in the Galápagos is a collaborative effort that provides applied research experiences in invasive species ecology to UH Mānoa undergraduate students from across campus,” said Creighton Litton, Department of Natural Resources and Environmental Management professor, (UROP) director, and one of the eight UH Mānoa faculty members who designed and implemented the program over the past three years. “The success of this program stems from committed research mentors from both UH Mānoa and the Charles Darwin Foundation, financial support from NSF and UH Mānoa and, most importantly, fully engaged students from our campus who commit to a full research experience, from learning the basics and developing proposals on campus in the spring, to field data collection, analysis and write-up in the summer.”

This opportunity is the result of a collaboration between UH Mānoa and the Charles Darwin Foundation, and is funded by the National Science Foundation–International Research Experiences for Students, the UH Mānoa Provost’s Office to align the overall program with the campus goal of becoming a Native Hawaiian Place of Learning and the UH Mānoa Office of the Vice Provost for Research and Scholarship.

The deadline to apply for the 2026 program is October 15. .

A new online resource aims to make learning about �鶹��ý’s rare and endangered native plants easier for students, teachers and the community—and the University of �鶹��ý is playing a key role.

, with support from UH ��ā�ԴDz�’s and other partners, has launched , a free website that gathers lesson plans, classroom activities, multimedia tools and student-friendly content in one place. The site is designed to help educators bring native plant conservation into classrooms and inspire future environmental stewards.

“Hua ʻIke makes it easier than ever for educators and students to connect with the incredible diversity of �鶹��ý’s native plants,” said Raedelle Van Fossen, education manager at UH ��ā�ԴDz�’s Lyon Arboretum, advisor for the Hua ʻIke project and member of the Laukahi Advisory Council. “By sharing this knowledge, we’re helping grow the next generation of conservation leaders.”

Hua ʻIke, meaning “seed or fruit of knowledge,” reflects the idea that knowledge, like a seed, can grow across generations. Visitors to the site can explore interactive materials, learn conservation stories and connect with a community of educators and learners.

Laukahi was formed in 2016 to implement the �鶹��ý Strategy for Plant Conservation, aligning statewide efforts to protect native species, nearly half of which are endangered. The organization’s mission is to unite conservation partners, expand awareness of �鶹��ý’s global biodiversity importance and prevent species extinction.

“Hua ʻIke came to life through the collective efforts of many—educators, conservationists, designers—all committed to supporting the next generation of stewards,” said Laukahi Network Coordinator Kimberly Shay. “Through Hua ʻIke, I feel optimistic for the future of �鶹��ý’s native plants as students discover the joy of connecting with them and caring for them.”

UH’s involvement includes faculty, staff and affiliates serving on Laukahi’s volunteer advisory council, contributing scientific expertise, educational outreach and project coordination. Lyon Arboretum’s participation ensures that botanical knowledge and cultural context remain central to the platform’s design.

Indigenous agroforests (food-producing agroecosystems where trees and crops grow together in forest-like environments) may offer valuable insights for addressing two of the world’s biggest challenges: declining biodiversity and rising non-communicable disease, according to research led by University of �鶹��ý at ����ԴDz� researchers. , the study found that agroforests with greater ecological diversity also offer a more nutritionally diverse food supply.

The team analyzed 48 Indigenous agroforests in Fiji using a trait-based framework. Focusing on specific plant characteristics important for ecological resilience, such as how their seeds are dispersed or how tall they grow, and traits important for human health and nutrition, such as carbohydrates, vitamin A or zinc, they measured the ecological and nutritional functional diversity in the agroforests. The findings showed that agroforests with a high diversity of traits important to ecological resilience—such as recovery after major weather disturbances—also support a wider range and depth of nutrients necessary to human health.

The results point to an important link between environmental management and nutritional resources. While much of modern agriculture focuses on high-yield, low-cost food production, this often comes at the expense of ecosystem health, nutritional diversity and downstream dietary quality. Agroforestry systems, by contrast, grow a variety of trees and plants in the same space, mimicking natural ecosystems and offering a greater diversity of edible and medicinal products.

“Fiji’s agroforests highlight the potential of biodiverse agroecosystems to contribute to climate-resilient and nutrition-sensitive agriculture,” said lead author Ashley McGuigan. “As we work to strengthen food systems that are rooted in place, responsive to climate change, and supportive of community health, this research underscores the importance of biodiversity, agroforestry, and local knowledge in food production.”

McGuigan is an extension specialist faculty member in UH ����ԴDz�’s at the (CTAHR) and a UH ����ԴDz� PhD graduate.

Supporting Indigenous knowledge and practices

The study also highlighted the importance of Indigenous knowledge and management practices. The agroforests in the study are stewarded by placed-based and multi-generational informed knowledge systems that are uniquely attuned to local social and ecological conditions, and have enabled resilience to varying levels and types of disasters and disturbances for millenia. Researchers said these knowledge systems and management practices are critical to support a transition towards food production systems that are not only more environmentally sound, but also nutritionally diverse and resilient to climate disruptions.

“Our findings support stronger investment in Indigenous and agroecological food production systems, both in the Pacific and globally,” McGuigan said. “We recommend working with practitioners to identify and record additional functions and traits, and use trait-based tools to help design food production systems that support ecological resilience and human nutrition. We urge policymakers to prioritize systems that reflect the interconnected nature of environmental and human health.”

The work was supported by the National Science Foundation, Fulbright Program and UH ����ԴDz�, among others. The other authors on the study include: Tamara Ticktin (UH ����ԴDz� School of Life Sciences), Rachel Novotny (UH ����ԴDz� CTAHR), Veniana Tikonavuli and Unaisi Vuli (The University of the South Pacific), and Abrania Marrero (Harvard University).

“Food production is a cornerstone of Fiji’s economy and community well-being,” Vuli said. “It provides essential food security and supports around 80% of rural livelihoods. Fiji is also increasingly reliant on imported goods, but supporting local food production helps strengthen resilience against climate and economic shocks.”
