Honu emerge as reef defenders against invasive algae in Northwestern Hawaiian Islands /news/2026/04/19/honu-emerge-as-reef-defenders/ Sun, 19 Apr 2026 18:00:30 +0000 /news/?p=232477 Hawaiian green sea turtles have been documented for the first time actively grazing on Chondria tumulosa.

An invasive algae already well-established in the Northwestern Hawaiian Islands is raising concern among researchers as it threatens to spread into the main Hawaiian Islands. Scientists from the University of Hawaiʻi at Mānoa and the U.S. Fish and Wildlife Service (USFWS) have identified a potential ally in slowing its advance: sea turtles.

Hawaiian green sea turtles (honu) have been documented for the first time actively grazing on Chondria tumulosa, an aggressive invasive red alga that has spread rapidly across reefs among three of the northernmost atolls in Papahānaumokuākea Marine National Monument (PMNM).

The findings, recently published in the journal by researchers, suggest that honu may play a meaningful role in controlling this ecologically damaging species—while also potentially spreading it.

“After these exciting finds, our multi-partner effort to prevent this seaweed from taking hold in the Main Hawaiian Islands must include a plan to increase numbers of threatened, native green sea turtles, as well as ramping up efforts to identify all routes that could allow Chondria to spread to Oʻahu,” said Celia Smith, Vlogٷ Mānoa‘s professor and senior author of the study.

Vlogٷ Mānoa researchers captured the first footage of green sea turtles helping control aggressive invasive algae.

Dangers of C. tumulosa

First detected at Manawai (Pearl and Hermes Atoll) in 2016, C. tumulosa has since expanded to more than 101 square kilometers of reef habitat (nearly the size of Kahoʻolawe), including Kuaihelani (Midway Atoll) in 2021 and Hōlanikū (Kure Atoll) in 2022. The alga forms dense mats more than 6 centimeters thick that can smother live coral and displace native reef species, making it one of the most pressing threats to the monument’s reef ecosystems.

Turtles take a bite

Native honu are acting as reef defenders by grazing on invasive algae that threaten Papahānaumokuākea coral.

Using a stationary GoPro camera deployed on a reef at Midway Atoll in June and July 2025, the research team captured approximately 50 minutes of footage showing three honu grazing on C. tumulosa mats. One female took up to 18 bites in a 95-second burst, leaving disruptions 5–15 cm in diameter across the algal canopy—substantially larger than what urchins or fish could achieve. A complementary necropsy of a stranded adult female confirmed C. tumulosa fragments throughout her digestive tract, accounting for roughly 25% of the material in her esophagus and crop.

The invasive red alga Chondria tumulosa forms thick, suffocating mats that smother native coral and threaten Hawaiʻi’s reef ecosystems.

“These turtles are consuming a meaningful amount of this alga in a single foraging session,” said Tammy Summers, USFWS staff biologist and co-author of the study. “It’s exciting because it points to honu as a native megaherbivore with the potential to suppress C. tumulosa biomass—but it also raises important questions about whether fragments excreted during their migrations between atolls could accelerate the alga’s spread.”

The findings carry immediate management implications. Because 96% of Hawaiian green sea turtles nesting occurs at Lalo (French Frigate Shoals) before individuals disperse to foraging grounds across the archipelago, the authors recommend eDNA monitoring at Lalo to track potential spread of C. tumulosa beyond its known range.

The study was a collaboration between Vlogٷ Mānoa‘s School of Life Sciences and USFWS Midway Atoll National Wildlife Refuge, and was funded by USFWS Invasive Species Strike Team funds through a cooperative agreement with Vlogٷ Mānoa. Smith leads the Limu Lab at Vlogٷ Mānoa, where research on C. tumulosa physiology, distribution and ecology has been ongoing for several years. Other authors on the paper are Caroline Pott from USFWS and Angela Richards Donà from the School of Life Sciences.

This work was accomplished under permit numbers PMNM-2025-001, USFWS 274 Recovery Permit TE72088A-3, Recovery Sub-permit TE163899-2, NOAA Permit 21260, and 275 State of Hawaiʻi, Department of Land and Natural Resources Special Activity Permit 2026-01.

Georges Frem

Georges Frem, a University of Hawaiʻi at ԴDz graduate from Lebanon, traded a career in engineering for a future dedicated to science and service, inspired by the deep cultural values he encountered in Hawaiʻi.

Frem will cross the stage in December 2025 to accept his bachelor of science in biology from the Vlogٷ ԴDz , marking the completion of an academic journey that started and ended on opposite sides of the globe. After finishing his first degree in mechanical engineering at the American University of Beirut, Frem made a life-changing decision to pursue his true passion for nature and animals at Vlogٷ ԴDz.

From classroom to independent research

Amber Wright and Frem after his UROP presentation.

Frem pointed to his experience with the Vlogٷ ԴDz (UROP) as the single most valuable part of his academic career. After taking a BIOL 305 course with Associate Professor Amber Wright in fall 2024, he reached out to her about a project.

“We brainstormed ideas and decided to apply for a UROP grant to conduct field collections to gain insights about trophic interactions among lizards on Oʻahu through stable isotope analysis,” Frem said. “I secured the money and managed to conduct my own personal research project from start to finish.”

Frem has remained a part of the Wright lab and is currently writing a manuscript based on his UROP work for potential publication. “This immersion in the scientific process has served as extremely valuable data for the deliberation of my future career choice,” Frem said. “Having had the privilege to execute science in this manner has definitely incited me to consider a career as a scientist a lot more seriously.”

Inspired by kuleana

Frem came to Hawaiʻi partly looking for cultural exposure, but he wasn’t prepared for the commitment he found within the Vlogٷ community. He was surprised by the university’s role as a Native Hawaiian Place of Learning, integrating place-based science into academics and the collective consciousness.

“The fierce passion expressed by members of the Vlogٷ community when talking about Hawaiian culture and place-based science was surprising to me,” Frem said. “I was saddened by the realization that we Lebanese, seldom exhibit that same awareness, pride, and responsibility when it comes to our own culture and nation, especially as it relates to our unique ecosystems.”

This realization inspired him to act. He joined community work days and got a firsthand taste of the community’s sense of kuleana (responsibility). These efforts included:

  • Helping out at Vlogٷ’s Ka Papa Loʻi Kanewai and planting kalo (taro) at the Waimanālo Research Station.
  • Volunteering at Loko Ea fishpond to remove invasive grasses.
  • Assisting the ԴDz Cliff Restoration Project to remove invasive ginger.

“I have been humbled by the deep sense of care fostered by Vlogٷ and the Hawaiian community in general, and am deeply inspired to promote those same values in my own ʻ徱Բ,” he said.

Returning home

As his undergraduate journey ends, Frem is focused on how he can be useful to his home country, Lebanon.

“I know I want to contribute to Lebanon and bring forth the best in it,” he stated. His future will involve science, although he is still weighing options—possibly as a researcher studying Lebanon’s native ecosystems, or starting science-based businesses to fund community initiatives.

One thing is certain: he is ready for the next step. “I am most likely going to be applying to grad school, and my time here has undoubtedly prepared me very well for that,” Frem said.

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

Researchers at the University of Hawaiʻi 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 Vlogٷ 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 Hawaiʻi’s communities and economy,” said study co-author and Vlogٷ 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 Vlogٷ āԴDz’s , which supports student-led research and creative work. Collaborators included Vlogٷ Mānoa faculty Michael Norris and Jennifer Saito, graduate students Chiyoko Onouye and Thi Hai Au La, and University of Mississippi Assistant Professor and Vlogٷ Mānoa PhD graduate Rebecca Prescott.

The study is dedicated to the late Vlogٷ Mānoa Earth Sciences Professor Craig Glenn (1954–2024), whose pioneering research on submarine groundwater discharge in Hawaiʻi helped illuminate how freshwater and seawater interact along island coastlines, and to former Vlogٷ 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 Hawaiʻi’s unique coastal environments.

The event, which drew more than 200 people, spotlighted efforts to protect Hawaiʻi’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. Vlogٷors also had the opportunity to purchase plants grown by the arboretum and participate in keiki-friendly activities designed to foster awareness of native ecosystems.

Newly opened fruits of hōʻawa (Pittosporum flocculosum) are exposing their seeds to birds (left), but older fruits and seeds have withered on the plant without being consumed (right) because the seed-dispersing birds are extinct.

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 Vlogٷ Mānoa in the and interim director of .

two berries on a tree
The large seeds of Hawaiian lama trees (Diospyros sandwicensis) are no longer dispersed because native birds large enough to eat the fruits (top fruit) are extinct. Instead, introduced rats often eat and destroy the seeds (bottom fruit).

“Understanding how introduced species reshape ecological interactions is crucial for planning effective conservation strategies,” Drake said. “In Hawaiʻi, 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.

Hawaiʻi’s forests in danger

In Hawaiʻi, 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 Hawaiʻi, 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 will launch a for students who did not follow a traditional premedical track or who want an additional step to demonstrate readiness for professional school. Coordinated by the (JABSOM) with partners across multiple units, the program, which begins in fall 2026, strengthens academic preparation and creates new pathways into medical and health professions.

Students will take courses in physiology, genetics, biomedical ethics, immunology and statistics, with electives such as neuroscience. A highlight is access to gross anatomy labs—hands-on training typically reserved for medical students—providing rare early exposure to medical-level anatomy.

Building Hawaiʻi’s healthcare workforce

“This program reflects the strength of the Vlogٷ System as a whole,” said Samuel “Sam” Shomaker, JABSOM dean. “It brings together expertise from across our campuses to create an integrated program rooted in biomedical sciences, life sciences and public health. Just as importantly, this is about building Hawaiʻi’s workforce. By opening access to advanced scientific training and mentoring, we are broadening the pool of qualified applicants and strengthening the healthcare system that depends on them.”

…we aim to prepare students not only for professional schools but also for lifelong learning in biomedical science.
—Olivier LeSaux

Alex Stokes, program director and originator of the certificate, said the program fills a critical need. “Across Hawaiʻi, and especially on the neighbor islands, communities live every day with the reality of too few doctors. Not every student prepares for medical school during their undergraduate years. This certificate provides the extra step some need—whether to strengthen their foundation, gain exposure to courses like gross anatomy, or test themselves against the workload to confirm medicine is the right path.”

Faculty also see the program as a chance to connect science with service.

“The is proud to play a leading role,” said Olivier LeSaux, professor and chair of the department at JABSOM. “By combining rigorous coursework with exposure to diverse disciplines, we aim to prepare students not only for professional schools but also for lifelong learning in biomedical science. This certificate represents an important new pathway for students who want to pursue careers that improve health in Hawaiʻi and beyond.”

The effort is coordinated by JABSOM and involves its Departments of Cell and Molecular Biology, and , with contributions from the and the at Vlogٷ ԴDz.

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 Hawaiʻi.

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 Vlogٷ āԴDz’s and co-author of the , recognized the coral while reviewing research from colleagues in China. His earlier work in Hawaiʻi 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 Vlogٷ’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 Hawaiʻi 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 Vlogٷ 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 Vlogٷ 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.

“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.”

Applications for the Tyler Fellowship for summer 2026 are expected to open in spring 2026.

From tracking invasive marine species, to exploring vegetation recovery on degraded, uninhabited islands, to studying tiny beetles threatening mangroves, eight University of Hawaiʻi 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 Vlogٷ Mānoa, and guided by research mentors from Vlogٷ 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 Hawaiʻi.

“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 Vlogٷ Mānoa undergraduate students from across campus,” said Creighton Litton, Department of Natural Resources and Environmental Management professor, (UROP) director, and one of the eight Vlogٷ 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 Vlogٷ Mānoa and the Charles Darwin Foundation, financial support from NSF and Vlogٷ 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 Vlogٷ Mānoa and the Charles Darwin Foundation, and is funded by the National Science Foundation–International Research Experiences for Students, the Vlogٷ Mānoa Provost’s Office to align the overall program with the campus goal of becoming a Native Hawaiian Place of Learning and the Vlogٷ Mānoa Office of the Vice Provost for Research and Scholarship.

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

With diverse expertise ranging from oceanography to economics to community-based coastal management, the University of Hawaiʻi hired eight new faculty members to support sustainable Pacific fisheries efforts. The new cohort of hires will develop an innovative graduate program to advance fisheries research, education, and training for sustainable management in Hawaiʻi and across the Pacific.

Fishing is essential to the way of life in Hawaiʻi and the Pacific, providing 50–90% of the protein for Pacific Islanders. However, management strategies from the U.S. continent often fail here because they were designed for cold-water, industrial fisheries. Pacific fisheries are different—they operate in warm tropical waters with diverse species and fishing gear, and with Indigenous Pacific Island communities. The Pacific Island region is multinational and has comparatively less scientific data, requiring a locally developed approach to ensure they can be sustained for generations.

“It is critically important to elevate and co-develop knowledge relevant to the Pacific, foster local expertise, and train the next generation of fisheries stewards and managers,” said Megan Donahue, director of the (HIMB) in the Vlogٷ Mānoa (SOEST). “The new faculty members in this cohort each bring unique perspectives and talent to the complexities we face here. In addition to their contributions to advancing research and sustainable management of Pacific fisheries, they will be a vital part of developing a fisheries graduate training program.”

Fisheries in Hawaiʻi are distinct in that they include a variety of sectors ranging from the open ocean longline fishery, which is the sixth largest fishery in monetary value in the U.S., to community managed fishponds or loko iʻa. Importantly, the majority of nearshore fisheries in Hawaiʻi are non-commercial, which requires unique considerations for management. This program seeks to build on existing work by faculty and practitioners across the Vlogٷ System to understand the unique contributions of these diverse commercial and non-commercial fisheries to the economic, social, and cultural well-being of Hawaiʻi to ensure their longevity.

“This cohort of new hires will take fisheries at Vlogٷ to the next level to better serve students, communities, fishers, government agencies and conservation organizations in Hawaiʻi and across the Pacific,” said Jeff Drazen, professor in the SOEST Department of Oceanography. “Our vision with this cohort is to stand up a center of expertise and excellence to facilitate the synergistic work that Vlogٷ is uniquely positioned to contribute.”

Developing the graduate education program

In Hawaiʻi, the Division of Aquatic Resources, the Western Pacific Fisheries Management Council, and NOAA’s Pacific Islands Fisheries Science Center have noted the need for greater local research and management capacity. This graduate program will be distinguished from others by creating learning opportunities for students to weave western science and Indigenous knowledge in collaboration with communities, and supporting community-based fisheries solutions and participatory governance approaches.

“We are thrilled to welcome the new fisheries cohort, whose work will significantly enhance Pacific Island fisheries,” said Brian Neilson, Administrator of the Hawaiʻi Division of Aquatic Resources. “By advancing research and cultivating the next generation of scientists, practitioners, and managers with social and cultural competencies tailored to Pacific Island communities, this initiative will benefit Hawaiʻi and our island neighbors.”

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

, with support from Vlogٷ āԴDz’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 Hawaiʻi’s native plants,” said Raedelle Van Fossen, education manager at Vlogٷ āԴDz’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. Vlogٷors 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 Hawaiʻi 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 Hawaiʻi’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 Hawaiʻi’s native plants as students discover the joy of connecting with them and caring for them.”

Vlogٷ’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.

Members of the Laukahi Advisory Council with Vlogٷ ties:

  • Mark Burgman, Vlogٷ Mānoa, School of Life Sciences director
  • Don Drake, Lyon Arboretum interim director
  • Elliott Parsons, Vlogٷ Pacific Regional Invasive Species and Climate Change Management Network specialist

More ecological diversity means better nutritional resources in Fiji’s agroforests /news/2025/07/21/more-ecological-diversity-better-nutrition/ Mon, 21 Jul 2025 20:38:15 +0000 /news/?p=218890 Vlogٷ researchers found that more diverse agroforests in Fiji also offer richer nutritional benefits for local communities.

Fresh harvest from a Fijian agroforest. Vlogٷ research shows diverse ecosystems like this support better nutrition and climate resilience.

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 Hawaiʻi at ԴDz researchers. , the study found that agroforests with greater ecological diversity also offer a more nutritionally diverse food supply.

Trees and crops grow together in a Fijian agroforest, creating a diverse system that supports both ecosystem health and human nutrition.

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 Vlogٷ ԴDz’s at the (CTAHR) and a Vlogٷ ԴDz PhD graduate.

Supporting Indigenous knowledge and practices

Trees and crops grow together in a Fijian agroforest, creating a diverse system that supports both ecosystem health and human nutrition.

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 Vlogٷ ԴDz, among others. The other authors on the study include: Tamara Ticktin (Vlogٷ ԴDz School of Life Sciences), Rachel Novotny (Vlogٷ 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.”

University of Hawaiʻi at ԴDz’s Health and Stranding Lab (VlogٷHSL) scientists are concerned after three striped dolphins stranded on east Oʻahu shorelines over seven days and tested positive for Brucella ceti, a bacterial infection that can transfer from animals to humans. The Vlogٷ researchers say the three cases could signal a much larger problem for dolphins and whales in Hawaiian waters.

Two of the dolphins were found in Waimānalo on June 7 and 8, and the third was found in Waikāne on June 15. Cultural practitioners were present at each response and advised the Vlogٷ first response team.

Public urged to keep distance, report strandings

In humans, the infection can cause flu-like symptoms, neurological issues and chronic arthritis if untreated.

Brucella ceti can be dangerous to humans who touch infected marine mammals,” said Kristi West, associate researcher at Vlogٷ ԴDz’s (CTAHR) who directs the university’s Health and Stranding Lab. “It is best to be cautious and avoid touching or handling stranded animals. We strongly urge the public to report any whales and dolphins in distress in the ocean or stranded on beaches.”

Since most carcasses are never recovered, public reporting is critical for understanding threats to marine mammal health.

“Dolphins and whales are recognized sentinels of ocean health and give us signs and signals about what’s happening out there,” said West. “Three strandings within one week likely represents many more dolphins that died and were lost at sea. It raises our concern about what’s happening to the animals in their ecosystem.”

New bacteria strain

CTAHR researchers identified striped dolphins as especially vulnerable to Brucella ceti and discovered the bacteria in other species of stranded dolphins and whales. The researchers published their findings in the in May. Between 2000 and 2024, they found the bacteria in seven species including pygmy killer whales, sperm whales, spinner dolphins and a Longman’s beaked whale. Many of the animals that tested positive showed severe brain and lung infections, with coinfections by viruses such as morbillivirus and herpesvirus.

Working alongside Vlogٷ Manoa microbiologist Michael Norris, the team has recently discovered a new strain of Brucella ceti in Hawaiian marine mammals that is likely the cause of the recent strandings. Work is ongoing and Vlogٷ will continue its investigations this summer.

This research is made possible through a Zoonotic Disease Initiative grant from the U.S. Fish and Wildlife Service to the Hawaiʻi Department of Land and Natural Resources.

Report dolphin/whale strandings

Sightings of dead or distressed marine mammals can be reported to the toll-free statewide NOAA Marine Wildlife Hotline at 1(888) 256-9840.

Robert Thomson

World Turtle Day is May 23. University of Hawaiʻi at ԴDz Professor Robert Thomson is an expert on evolutionary and conservation biology, and much of his research focuses on the evolutionary history of turtles. Thomson shared his thoughts on World Turtle Day, and the challenges turtles are facing in Hawaiʻi and around the world.

Why should turtles be celebrated?

green sea turtle swimming in the ocean

It’s an opportunity to recognize an important component of biodiversity that often gets ignored. Something to know about turtles is that they’re both extraordinarily ancient—older than dinosaurs, they’re older than mammals, birds, almost any other vertebrate you’ll see on the Hawaiian landscape—and they’re extraordinarily endangered. Around 60% of species are threatened with extinction today.

Your previous research highlights that turtles face a “daunting future.” What are the biggest threats to their survival today?

There’s two major threats in particular and they’re threats that are shared by a lot of biodiversity today. One is loss of habitat. Turtles have a lot of their species richness on coastlines, in rivers and other aquatic habitats that humans tend to modify and degrade in important ways. Because of this, turtles are experiencing wholesale habitat loss at an enormous scale for the last century. The second thing that influences turtle conservation is collection—both for pet trade and the food trade, as well as traditional cultural uses.

Can you explain how climate change is affecting turtle populations, especially here in Hawaiʻi?

As global sea levels rise, they’re losing nesting beaches, places where they lay their eggs. A recent example of that happened in 2018. In the Northwest Hawaiian Islands, there’s a particular islet in French Frigate Shoals called East Island, that was the nesting area for around 95% of all green sea turtles in Hawaiʻi. It’s a huge amount of the population. A major storm came through and wiped that island off the map. It was gone. That led to a lot of concern that this is the sort of thing we expect to see as the climate continues to change and storms become more powerful and sea levels rise. The good news, at least in the short term, is the island is now reforming. Crews went out last year, and that island once again exists, and it has turtles nesting on it.

How hopeful are you that conservation efforts can help turtle populations in the future?

This is the big question in biodiversity conservation. The hope comes from the idea that this is no longer a scientific mystery. We know what is causing the declines, and in many cases we know how to fix them. We need to protect habitats. We need to restore habitats. We need to stop market trade. The question is whether there is societal and political will to deal with these problems that we already have solutions for, and will we do that quickly enough before these declines turn into extinctions.

Turtles have been around for millions of years. What can they teach us about resilience, survival or even vulnerability in today’s world?

This is a lineage that has existed for 200 million years. That’s a length of time that we truly can’t comprehend. Now, just in the last few centuries, we’re seeing dramatic extinctions and global endangerment. So it shows the impact that humans are having on natural environments and on biodiversity broadly. If this lineage that has been stable and resilient through hundreds of millions of years—through the mass extinction that killed the dinosaurs—is suddenly globally endangered, that speaks to the severity of the impacts that we are having on native ecosystems.

What can people do to help protect turtles and their habitats, both in Hawaiʻi and globally?

You can use what tools you have available to you to support wildlife conservation, particularly habitat conservation. I think in the United States, there’s not many people participating in turtle markets anymore other than in the pet trade, so this issue sometimes gets ignored. But there is still significant commercial collection of turtles that, in turn, get shipped to market in other countries. Wild populations can not sustain this. Other than that, the biggest messages are the same messages as support for biodiversity conservation generally: protecting habitats, advocacy for sustainable systems and voting in ways that help save ecosystems.

A hands-on learning initiative designed to introduce Hawaiʻi preschool keiki and their ʻohana (families) to STEAM (science, technology, engineering, agriculture and mathematics) concepts is expanding, thanks to funding from the University of Hawaiʻi at ԴDz’s (UROP).

The S.T.E.A.M. on the Bookshelf program, developed in collaboration with Vlogٷ ԴDz’s (CTAHR) Cooperative Extension faculty with initial funding from the Maui County Department of Agriculture, has already engaged over 200 ʻohana on Maui. Designed to support parent-child learning, the program provides preschoolers with themed books, interactive activities and family workbooks aimed at making STEAM curriculum accessible in a home-based setting.

“Parents state that their children love completing the learning activities and often request the books as bedtime stories,” Vlogٷ ԴDz Instructor Chad Junkermeier said. “We’ve heard from parents that were in the program that their children are now reading the books to younger siblings.”

Bringing learning home

The initiative builds on an idea first proposed nearly 15 years ago by Heather Greenwood, a Vlogٷ CTAHR associate extension agent based on Maui. Recognizing that many Head Start ʻohana struggled to attend evening financial and nutrition training sessions, she helped develop a model where young children brought home books and activities covering these topics, effectively engaging parents through their children’s learning experiences. This project built on the initial model, enhancing it to incorporate more parent-child interaction and hands-on learning.

The initial age-appropriate physics and engineering curriculum was piloted with families and Vlogٷ Maui College faculty and staff in 2021. With additional funding from the Maui County Department of Agriculture in 2023–24, the project expanded to include an agriculture and gardening curriculum, reaching 213 ʻohana across 15 preschool classrooms that school year.

Of the physics and engineering curriculum, one of the preschool parents stated, “They are learning advanced concepts in an easy to [understand] format.”

With support from Vlogٷ ԴDz’s Undergraduate Research Opportunities Program’s , two undergraduate students will work with the team to refine and expand the physics and engineering curriculum into three tracks: physics, astronomy and engineering. The funding, totaling $10,000, will allow the team to develop engaging learning activities tailored for young children.

As the program grows, efforts are also underway to incorporate new subject areas. Vlogٷ ԴDz Associate Professor Sladjana Prišić has joined the project to develop a microbiology curriculum, further broadening the educational scope of S.T.E.A.M. on the Bookshelf.

The program’s success is gaining academic recognition, with its first peer-reviewed manuscript recently accepted for publication in the Journal of Extension. The study highlights the effectiveness of the home-based model in fostering early STEAM learning and strengthening family engagement.

Undergraduate students from the University of Hawaiʻi at ԴDz traveled to Washington, D.C., in March, as part of the (STR) program. Chloé Houy, Kayla Lum and Kristyn Miyamoto participated in months of research advocacy training, preparing them to effectively communicate the importance of undergraduate research to policymakers. They are mentored by Associate Professor Sladjana Prišić and work on research projects in the Prišić Lab.

Their training, which began in November 2024, included workshops on relationship building with legislators, writing policy briefs and crafting persuasive op-eds. The students’ efforts culminated in meetings with the offices of Sen. Mazie Hirono, Sen. Brian Schatz and Rep. Ed Case.

Drawing from their experiences conducting microbiology research in the Prišić Lab, the students highlighted how undergraduate research fosters scientific discovery and professional development. They emphasized the critical role of federal support from agencies such as the National Science Foundation and the National Institutes of Health in sustaining research opportunities that shape future scientists and medical professionals.

“Advocating for undergraduate research on Capitol Hill was an incredible experience that showed me how science and policy intersect to shape the future of research opportunities,” Lum said.

Prišić added, “Seeing my students confidently communicate the impact of their research to policymakers reinforced the importance of mentorship and the role of advocacy in advancing scientific discovery.”

Through the STR program, the students gained hands-on experience in research advocacy while refining their ability to communicate scientific concepts to a broad audience. Their participation not only amplified the value of student research at Vlogٷ but also underscored the broader impact of continued investment in scientific exploration and education. Their research and trip were funded by the Vlogٷ ԴDz (UROP) and a grant from the National Science Foundation awarded to Prišić.

Expanding support for undergraduate research

Noah Perales-Estoesta, UROP program coordinator, also participated in the STR program. His goal was to explore how UROP can adapt programming similar to what is offered by STR for undergraduate students at Vlogٷ ԴDz.

“A major part of what UROP does is support the dissemination of student research and creative work, usually in the form of presentations and publications,” Perales-Estoesta said. “Especially in today’s university climate, I think we should be encouraging students to think more creatively about the broader impacts of their work and, from the administrative side, about how to provide them with the infrastructure to realize and articulate those impacts. STR provides a great model for this, and I look forward to exploring what similar efforts UROP can develop.”

Each year, UROP awards more than $500,000 in merit-based scholarships directly to students to support mentored undergraduate research and creative work projects and presentations. An additional $135,000 is awarded directly to mentors to support undergraduate research and creative work during the summer via the .
