Column: Hunger games on Guam’s reefs

Reef Awareness Day Article Schills 1

World Reef Awareness Day on Tuesday provides a great opportunity to spotlight the unique natural heritage of Guam’s reefs and the strong cultural connection of the CHamoru people to this valuable resource.

In recent months, juvenile rabbitfish (mañahak) have traveled from various Micronesian islands to Guam and are now quarantining on the island’s reef flats. Much like our own children, these youngsters have an insatiable appetite and can curtail seaweed gardens on reefs where they couch surf.

In Pago Bay, extensive stands of the angel hair seaweed, a species that has been proliferating on Guam’s reefs since 2012, have now been decimated by these rabbitfish. This is a fine example of the biological control of a nuisance species without human assistance.

Mañahak are not picky eaters and they happily feast on the diversity of seaweeds that reefs have to offer. The impact of the rabbitfish raid was striking when I was desperately searching for seaweed during a recent field trip in Pago Bay.

When a boulder generously covered with bright green tufts of seaweed caught my eye, I thought I had struck gold. While plucking off these tufts, the boulder suddenly aroused and charged off at a whipping speed. The two eyes on the boulder glanced back and I realized that this huge stonefish had capitalized on the existing food scarcity by using seaweed camouflage to deceive its rabbitfish prey.

Mass spawning

Some seaweeds are untouchable by grazing fish. Vivid green clumps of turtleweed (Chlorodesmis fastigiata) stand out on reefs but are not targeted by herbivorous fish because they contain toxins.

Like rabbitfish, turtleweed releases offspring en masse when the conditions for their survival are optimal. Rabbitfish runs have evolved into seasonal events that coincide with the main growing season of seaweeds.

Turtleweed is more selective in timing its reproduction. Episodes of mass spawning by this seaweed occur when bare patches of reef become available in the aftermath of storm events. At that point, turtleweed is fully committed to reproduction and the whole seaweed is converted into reproductive cells after which the parent plant dies.

Faking a poisonous appearance

The camouflage trick of stonefish is topped by the disguise-by-resemblance (mimicry) strategy of the Piti Bomb Holes seaweed (Rhipilia coppejansii). Guam is home to several species of Rhipilia, which all form distinctive spongy blades.

The Piti Bomb Holes seaweed is only found on Guam and is unique in forming green tufts of loose filaments that resemble turtleweed. The chemical composition of the Piti Bomb Holes seaweed is as of yet unknown, but its apparent similarity to poisonous turtleweed might ensure its survival on reefs where herbivores abound.

Cultural traditions

Humans have become part of the natural dynamics on reefs. The mañahak season brings people together while catching, processing or feasting on this seasonal culinary delight. Observant fishermen are the first to witness the changes that are taking place on reefs. They have already adapted by using the overly abundant angel hair seaweed as fishing bait or as a crispy and tasty additive to salads.

Even in this day and age of magnificent nature documentaries and well stocked grocery stores, it remains important to celebrate and perpetuate cultural traditions that are deeply rooted in the island’s natural heritage. After all, such activities allow us to evaluate the health of our ecosystems and find solutions for environmental issues specific to Pacific islands.

Biology student discovers two potentially new species from Yap

5R5A1608

Gabriella Prelosky, an undergraduate biology student at the University of Guam, is in the process of naming two potentially new species of diatoms that she found while examining a mud sample from a mangrove in Yap. Diatoms are single-celled algae found in oceans, lakes, and rivers. 

“They’re primary producers, so they’re photosynthetic organisms,” said UOG Professor Emeritus of Biology Christopher Lobban, Prelosky’s mentor. “The other characteristic they have is that they’re the base of the food chain — they’re part of the reason why mangroves are rich areas. In freshwater studies, there’s been a push to know more about water quality, and diatoms act as water quality indicators.”

Prelosky is working in Lobban’s Microscopy Teaching & Research Laboratory on the UOG campus for a research fellowship with the NSF INCLUDES: SEAS Islands Alliance program, a $10 million initiative funded by the National Science Foundation to broaden participation in STEM fields of students in U.S. territories and affiliated islands.

In studying the mud sample, Prelosky came across a very long figure. 

She said, “I took a couple pictures and showed it to Dr. Lobban, and he said, ‘I’ve never seen anything like that before.”’ 

Lobban sent the pictures to a colleague, who identified the specimen as a member of the genus Gompotheca.

“At that point, we started thinking that we found something new,” Lobban said. “There are only two species in the genus Gompotheca, and they’re both characterized as being very rare. One species had been studied in a scanning electron microscope, and we can see the differences between them, so we know it wasn’t that one. The second one doesn’t even look like it belongs in the same genus.” 

A few weeks later, Prelosky found the second potentially new species from the same sample.

“Dr. Lobban noticed that it looked like a different species,” Prelosky said. “But what was distinct about it is that it had these arches and these flaps. He looked more into it and said it was probably a new species as well.” 

According to Lobban, new species are being found all the time because marine tropical diatoms have not been extensively explored. Much of the literature on single-celled algae dates to the 1800s.

Both findings will officially be new species once a paper about the diatoms has been peer-reviewed and approved for publication.

‘I wanted to name them after people important to me’

In documenting and describing the species in a research paper, Prelosky will also get to name them. She announced the names at the first annual UOG STEM Conference, which took place virtually from April 16–17. 

“The first one is named Gompotheca marciae,” Prelosky said. “I talked to my parents about naming them after my two grandmothers: Mary from my dad’s side and Marcia from my mom’s. They have similar names, so it was easy to combine them.” 

Prelosky named the second one Campylodiscus tatreauae after Linda Tatreau, her former science teacher from George Washington High School. 

“I named it after her because she’s been such a helpful person in my journey to marine biology,” Prelosky said. “I thought it would be nice to name it after her because without her, I wouldn’t be where I am today.”

The NSF INCLUDES: SEAS Alliance is administered by the Center for Island Sustainability and the Sea Grant program at the University of Guam and collaborates closely with the Guam EPSCoR program, also funded by the National Science Foundation.

‘I think I’ve found my lifelong career’: Grad student publishes research as lead author

Coral Study Justin 1

Justin T. Berg, a graduate student in the Master of Science in Biology program, has achieved a personal first and, in the process, solidified the direction he wants to go with his career. As of February, he became a published lead author of scientific research. 

It was a study, which was funded by the university’s National Science Foundation EPSCoR grant, on the effects of shade on corals’ recovery time from heat stress, or coral bleaching, events. The researchers found that both light and temperature work together in coral bleaching events and that shading them greatly assists their recovery time. The paper is published in the peer-reviewed Marine Biology Research journal.

“I think I’ve found my lifelong career, which is extremely exciting,” Berg said. “I don’t think I’ll ever look back.”

This was the first time Berg had ever gone through the full process of writing a scientific paper to getting a project peer reviewed and published. He received support along the way and credits the Guam NSF EPSCoR program as well as Assistant Professor Bastian Bentlage, who supervised and also co-authored the study.

“Being first author is huge, especially when you’re looking into applying for a Ph.D. program,” Berg said. “I want to be able to be a professor one day and teach students and give them the opportunities I had.” 

Bentlage said a team of undergraduate and high school interns brought in by the Guam EPSCoR and NSF INCLUDES programs were also crucial in helping with the project’s experimental design and data collection. 

“It wouldn’t have been possible without all these students who were so keen on learning something new and helping my lab develop new approaches to study corals for us to use and add to our portfolio of tools,” Bentlage said. “We really went on this journey together.” 

Berg is expected to receive his master’s in biology at the end of this semester. He earned his bachelor’s from the University of Delaware, double majoring in biology and pre-veterinary medicine and animal biosciences with a minor in chemistry.

UOG study: Light, in addition to ocean temperature, plays role in coral bleaching

5R5A8743

A study by University of Guam researchers has found that shade can mitigate the effects of heat stress on corals. The study, which was funded by the university’s National Science Foundation EPSCoR grant, was published in February in the peer-reviewed Marine Biology Research journal.

“We wanted to see what role light has in coral bleaching,” said UOG Assistant  Professor and EPSCoR Co-PI Bastian Bentlage, the supervisor and co-author of the study. “Usually, people talk about temperature as a cause for bleaching, but we show that both light and temperature work together.

Previous UOG research led by EPSCoR Lead Researcher Laurie J. Raymundo found that more than one-third of all coral reefs in Guam were killed from 2013 to 2017 over the course of multiple bleaching events. Coral bleaching is the process in which corals stressed by environmental changes expel the essential symbiotic algae that live in their tissues, causing them to turn white and often die.

This latest study examined the resilience of staghorn corals (Acropora cf. pulchra) in heightened seawater temperatures. This species of coral is one of Guam’s dominant reef-builders, and its habitats experience temperatures up to 97 degrees Fahrenheit during the hottest months of the year, leaving it vulnerable to bleaching episodes and population decline.

A team of researchers — including lead author Justin T. Berg, a UOG graduate student and EPSCoR Graduate Research Assistant (GRA) studying biology; Charlotte M. David, an undergraduate student from the University of Plymouth (England), and Melissa Gabriel, a UOG graduate student and EPSCoR GRA studying environmental science — took coral samples from the Hagåtña reef flat and examined their health in the UOG Marine Laboratory under normal and elevated temperatures.

“One group was subjected to consistent baseline temperatures observed on Guam’s reef flats,” Bentlage said, “and another was set to temperatures that are projected to become the new normal over the next couple of decades.”  

The researchers found that the corals took three weeks to recover from a week-long heat stress event. The experiment was then replicated to see how the corals would react if they were given shade while subjected to warmer temperatures.

“We found that when we put the shading over coral with increased seawater temperatures, it greatly increased photosynthetic yield of the symbiotic algae. Shade made a huge difference for coral health when you have high temperatures,” Berg said.

Implications for reef management

Shading is a practice already used in coral nurseries, Bentlage said, but it may not be practical to shade whole reefs in the ocean. Future studies can look into practical ways to reduce the impact of light on corals, particularly as they recover from periods of elevated temperatures.

“We saw the corals recover rather slowly,” Berg said. “The length of recovery indicates that corals are vulnerable during this time and management efforts may be particularly necessary during this period to reduce coral mortality.” 

Berg said the new knowledge may also help inform the best locations to successfully outplant corals.

“For example, slightly turbid waters could provide some shading to corals, making them less likely to bleach during periods of elevated sea surface temperatures,” Berg said.

UOG welcomes back to shore the first Pacific Islander to reach the deepest point of the ocean

5R5A9761

University of Guam President Thomas W. Krise, along with representatives from UOG Sea Grant and Guam EPSCoR, greeted Nicole Yamase on her return from the deepest known point in the world’s oceans on March 13, 2021, at the Port Authority of Guam.

Yamase, a native of Pohnpei in the Federated States of Micronesia and a Ph.D. candidate at the University of Hawai’i, made history the week of March 8, 2021, as the first Pacific Islander to descend to the ocean’s deepest known point — the Challenger Deep in the Mariana Trench.

Yamase’s voyage took place in the Limiting Factor, a commercial deep-submergence vehicle that holds the record for the deepest manned descent in the Challenger Deep. The full dive took 10 hours and reached 35,764 feet below sea level.

“This expedition was not only an opportunity to conduct science but also an opportunity to share my culture with the world,” Yamase said.

For her trip, Yamase brought two FSM flags along with a small wooden canoe in honor of her ancestors.

In addition to the UOG teams, Yamase was welcomed to shore by Port Authority General Manager Rory Respicio and representatives from the Micronesia Conservation Trust and The Micronesia Challenge.

As a recipient of the Bill Raynor Micronesia Challenge Scholarship, which is awarded through Micronesia Conservation Trust, Yamase was asked by the Micronesia Conservation Trust to represent the FSM on this voyage.

After departing on March 8 for a 30-hour journey to the Mariana Trench aboard the research vessel Pressure Drop, Yamase dove in the Limiting Factor, the world’s only private submersible capable of reaching “full ocean depth” of 36,000 feet. The vehicle, a Triton Submarines 36000/2, was piloted by Victor Vescovo, a world record holder, researcher, scientist, and adventurer.

“It was an honor to be there for Nicole when she returned to land and celebrate her historic accomplishment,” said Austin Shelton, director of UOG Sea Grant and a board member of the Micronesia Conservation Trust. “I’m so thankful and excited for all the new Micronesian marine scientists she is surely inspiring.”

Yamase’s research focuses on the effects of climate change on the marine plant community to help predict the future health of coral reefs. Yamase has now returned back to Hawaii to continue her doctoral studies.

In the past, the UOG Marine Laboratory has collaborated on voyages to the Mariana Trench, most notably on James Cameron’s National Geographic and Rolex Deepsea Challenger expedition in 2012.

University of Guam secures $20 million to expand coral research

2019 uog biorepository kelokelo web
2019 uog biorepository kelokelo web
Mildred Kelokelo, a graduate biology student at the University of Guam, documents a reef fish using equipment in the University of Guam Biorepository in 2019. The biorepository, established under the five-year Guam Ecosystems Collaboratorium grant project, is an online-accessible collection of specimens facilitating marine biodiversity research.

The University of Guam has been awarded $20 million to expand its research capabilities on coral reef survival in rapidly changing environmental conditions. The five-year grant is from the National Science Foundation’s Established Program to Stimulate Competitive Research, more commonly referred to as EPSCoR, and will considerably expand upon work undertaken during the previous five-year, $6 million Guam EPSCoR grant project, the Guam Ecosystems Collaboratorium.

“This is a major grant award which not only validates and expands on the research work of Guam EPSCoR, our Marine Laboratory, and our partners, but it also further establishes the University of Guam as an emergent research institution in the Pacific region,” said UOG President Thomas W. Krise.

Starting July 1, the new grant project — titled the Guam Ecosystems Collaboratorium for Corals and Oceans, or GECCO — will increase the collection, documentation, integration, and analyses of complex genetic and oceanographic data from reefs within the region. These research activities are necessary to understand the evolutionary and ecological processes that drive resilience in coral reefs under stress from climate change and other factors and could provide valuable insight into the development of
viable management strategies.

Dr. Terry J. Donaldson, professor of ichthyology at the UOG Marine Laboratory and the principal investigator and project director, said the need for modern, cutting-edge studies on reef ecosystems is urgent.

“Island communities of the Western Pacific and all around the world depend on coral reef ecosystems, but the reefs are struggling to survive amid our rapidly changing climate,” he said. “Guam has the nation’s most diverse and complex coral reefs, so the UOG Marine Lab is the best place to do this research and inform how we can better protect this vital ecosystem.”

Data collection

The research team, led by Dr. Bastian Bentlage, assistant professor of bioinformatics at the Marine Lab, will collect and analyze genetic, genomic, oceanographic, and ecological data sets. New collections of marine biodiversity from the region will be curated, imaged, and mapped, and specimens — including cryo-preserved tissues for genomics research — stored in the UOG Biorepository along with historical collections dating back more than 50 years. Specimens and field collection data will be digitized and posted in the biorepository’s online-accessible database that was established during the Guam Ecosystems Collaboratorium, providing the scientific community with an invaluable resource for marine biodiversity research.

Big-data analyses

Mathematical models will use the data gathered to better predict changes in our reef ecosystems. To facilitate this ambitious research project, UOG’s ability to conduct big-data analyses will be expanded by establishing a high-performance computing cluster on its campus and by strengthening its collaborative network with other research institutions.

Techniques and technology

The new grant will utilize cutting-edge instrumentation and innovative techniques, including:

  • hyperspectral scanning to automate mapping of reef communities;
  • DNA barcoding to facilitate identification of reef organisms, including coral microbiomes, and their role in the stress response of coral reefs;
  • seascape genomics, integrating genomics, and oceanographic modeling to trace connectivity between coral reefs within the region; and
  • micro-CT scanning techniques within the Biorepository to further the understanding of the morphology of marine organisms on reefs and promote a greater understanding of their taxonomic diversity.

“Coral reefs in the Marianas Archipelago are some of the most diverse ecosystems in the world, and Guam represents the United States’ only foothold in the region. This award provides researchers the opportunity to explore these coral reef systems and understand current biodiversity challenges concerning how they respond to climate change,” said NSF EPSCoR Program Manager John-David Swanson. “In addition to improving infrastructure in the jurisdiction, this project aims to target underserved communities and develop innovative programs for STEM education and workforce development.” 

Education and collaboration

The grant will grow UOG’s research capacity by funding new and visiting faculty positions and post-doctoral fellowships to conduct research, teach specialized courses at the university, and engage graduate and undergraduate students in research.

Beyond research, the GECCO project will develop innovative STEM education and community engagement programs — an effort that will led by Dr. Austin Shelton, assistant professor of extension and outreach — and collaborations within the national and international research communities, an effort that will be led by Dr. Rachael Leon Guerrero, vice provost for research and sponsored programs.
