Five students gain valuable experience through summer research program

(Photo by Merry Remetira) Over the course of eight weeks, five undergraduate students gained valuable scientific experience, discovered more about themselves, and explored different research areas through the NSF INCLUDES: SEAS Bridge to Ph.D. Program held at Pennsylvania State University. These student researchers include Louise Pascua, Gabriella Prelosky, Anela Duenas, Anna Aguirre, and Merry Remetira.

(Photo by Anna Aguirre) “There was definitely a learning curve with certain aspects of my research just because there were procedures or techniques that I haven’t done beforehand,” said Anna Aguirre, a biology student and a 2021 NSF SEAS research fellow. “However, I did my part with taking notes and trying to be as proactive in learning as I can be and suddenly the learning curve was not so intimidating.”

(Photo by Merry Remetira) “My main challenge is that I have insecurities when it comes to what I know and what I can offer,” said Merry Remetira, a civil engineering student and a 2021 NSF SEAS research fellow. “This in turn can make me fear reaching out to a mentor and explaining what I really feel. I tend to just accept what is instructed of me and try not to question anything. I was also advised to stop apologizing so much, that to only apologize when responsibility is due. That was a truly enlightening experience and I will work on that challenge.”

Before participating in the bridge program, I was almost certain I did not want to pursue a master’s degree after graduating next spring due to extreme burnout, but this program showed me both the highs and lows in a positive light. I now know that after a break, I am definitely going for a master’s,” said Gabriella Prelosky, a biology student and a 2021 NSF SEAS research fellow. “My advice for this program, but also others, be confident in yourself. Things may not go how you want it the first time, but the more you fall, the more you learn!”

I was able to do research on something I had zero experience in which was terrifying but also very enjoyable,” said Louise Pascua, a biology major and a 2022 Guam NSF EPSCoR student researcher. “It's a little cliche to say, however I do believe that my love for science has been re-ignited. I made many life-long friends and built many professional relationships, while also finding myself.”

(Photo by Anela Duenas) “This program made me realize that I am more interested in the ecological aspects of research after working with more hands-on activities in the greenhouse for my project,” said Anela Duenas, a biology major and 2021 NSF SEAS research fellow. “I also experienced a culture shock when first arriving to the United States as it was my first time. A culture shock not only because of a new location but also in science. It was incredible to witness the laboratories and equipment available to students at Pennsylvania State University. Overall, it was very eye opening and made me excited to be in this field.”

Over the course of eight weeks, five undergraduate students gained valuable scientific experience, discovered more about themselves, and explored different research areas through the NSF INCLUDES: SEAS Bridge to Ph.D. Program held at Pennsylvania State University.

These student researchers include Louise Pascua, Gabriella Prelosky, Anela Duenas, Anna Aguirre, and Merry Remetira.

For these student researchers, it was their first time participating in an off-island research program. The program was held from June to August 2022.

“My experience during the summer was so much fun! I was able to do research on something I had zero experience in which was terrifying but also very enjoyable,” said Louise Pascua, a biology major and a 2022 Guam NSF EPSCoR student researcher. “It’s a little cliche to say, however I do believe that my love for science has been re-ignited. I made many life-long friends and built many professional relationships, while also finding myself.”

During the program, Pascua was placed under the mentorship of Jason Rasgon, an entomology professor at PSU. For her independent research project, she focused on genetically modifying eye color in Culex tarsalis mosquitoes using ReMOT Control. ReMOT Control is similar to CRISPR technology however ReMOT Control injects the adults to send the gene cutting complex to the embryos rather than injecting the embryos directly, according to Pascua.

Anela Duenas, a biology major and 2021 NSF SEAS research fellow, experienced some culture shock when it came to conducting research in a new environment.

“This program made me realize that I am more interested in the ecological aspects of research after working with more hands-on activities in the greenhouse for my project,” said Duenas. “I also experienced a culture shock when first arriving to the United States as it was my first time. A culture shock not only because of a new location but also in science. It was incredible to witness the laboratories and equipment available to students at Pennsylvania State University. Overall, it was very eye opening and made me excited to be in this field.”

Under the mentorship of Francesco Di Gioia, an assistant professor at PSU, Duenas studied alternative growing media for the production of microgreens.

Over the course of the program, the student researchers faced challenges and research areas they were not familiar with all while gaining the skills and knowledge to become confident in their ability to adapt and persevere.

“There was definitely a learning curve with certain aspects of my research just because there were procedures or techniques that I haven’t done beforehand,” said Anna Aguirre, a biology student and a 2021 NSF SEAS research fellow. “However, I did my part with taking notes and trying to be as proactive in learning as I can be and suddenly the learning curve was not so intimidating.”

Aguirre studied plant pathology and environmental microbiology under Sharifa Crandall, an assistant professor at PSU. For her project, she looked at how soil steaming and later final beneficial and pathogenic amendments might affect plant growth.

For one student, this experience helped them learn how to speak up when they need help.

“My main challenge is that I have insecurities when it comes to what I know and what I can offer,” said Merry Remetira, a civil engineering student and a 2021 NSF SEAS research fellow. “This in turn can make me fear reaching out to a mentor and explaining what I really feel. I tend to just accept what is instructed of me and try not to question anything. I was also advised to stop apologizing so much, that to only apologize when responsibility is due. That was a truly enlightening experience and I will work on that challenge.”

Remetira was mentored by Margaret Byron, an assistant professor of mechanical engineering at PSU. For her project, she studied how oil-particle aggregates formed using a roller tank to simulate how particles would interact in the environment.

For Gabriella Prelosky, a biology student and a 2021 NSF SEAS research fellow, being in the program helped renew her excitement for science and her future.

Prelosky studied under Natalie Boyle, an assistant research professor at PSU. Her research project involved calculating the lethal dose curve of 50% of alfalfa leaf cutting bees using an insecticide compound known as acetamiprid in varying doses.

“This experience most definitely has affected my goals. Before participating in the bridge program, I was almost certain I did not want to pursue a master’s degree after graduating next spring due to extreme burnout, but this program showed me both the highs and lows in a positive light. I now know that after a break, I am definitely going for a master’s,” said Prelosky. “My advice for this program, but also others, be confident in yourself. Things may not go how you want it the first time, but the more you fall, the more you learn!”

Graduate students publish paper on upside-down jellyfish

A new study by University of Guam researchers has found that differences in upside-down jellyfish populations found in Guam waters may be environmentally driven. The study, which was funded by the university’s National Science Foundation EPSCoR grant, was published in May in Zoomorphology, a peer-reviewed journal that focuses on the form and structure of invertebrates and vertebrates.

Upside-down jellyfish spend most of their time with their bells resting on the seafloor of shallow, coastal waters. By lying upside-down, the jellyfish expose the photosymbiotic algae living inside their arms toward the sun. Photosymbiosis is a type of symbiotic relationship between two organisms in which one organism is capable of photosynthesis.

A new study by University of Guam researchers has found that differences in upside-down jellyfish (Cassiopea ornata) populations found in Guam waters may be environmentally driven.

The study, which was funded by the university’s National Science Foundation EPSCoR grant, was published in May in Zoomorphology, a peer-reviewed journal that focuses on the form and structure of invertebrates and vertebrates.

Upside-down jellyfish spend most of their time with their bells resting on the seafloor of shallow, coastal waters. By lying upside-down, the jellyfish expose the photosymbiotic algae living inside their arms toward the sun. Photosymbiosis is a type of symbiotic relationship between two organisms in which one organism is capable of photosynthesis.

Upside-down jellyfish can sustain themselves off the byproducts of the algae and can capture zooplankton for additional energy to grow.

The study involved examining two upside-down jellyfish populations from Cocos Lagoon and Piti Channel. Because both populations were different in size, color, and shape, the researchers initially thought they were two different species.

“Upon doing a little genetic work, we determined that they were the same species. So instead of it being species-level morphology differences, we determined that it was environment-level morphology differences,” said lead author Colin Anthony, a UOG graduate student studying biology. “The environments we pulled them from are very different. Cocos Lagoon had turbid, sediment-laden water and the water in Piti Channel was very clear.”

According to the study, it may be possible that these different environments affect the way these jellyfish acquire sustenance.

“If they’re in a little more turbid or muddy water, they may rely more on their hunting skills and releasing their stinging structures and using heterotrophy to feed versus if they’re in clearer water, they would use more photosynthetic capabilities,” said co-author MacKenzie Heagy, a UOG graduate student studying biology.

Studying upside jellyfish is important for several reasons: some species are considered invasive, with the potential to impact the use of waterways when congregating in large numbers. Upside-down jellyfish can also serve as environmental indicators for nutrient pollution and microplastics.

Because they are close relatives of corals, which also share the same bond with photosymbiotic algae, upside-down jellyfish are being used as a model to study coral without having to harm coral populations.

A community effort

This project would not have been possible without the community at the UOG Marine Laboratory and was a collaborative effort of two researchers in different disciplines. Under the mentorship of UOG Associate Professor Bastian Bentlage, Anthony studies cnidarians such as jellyfish, coral, and hydroids while Heagy studies algae, which are photosynthetic organisms, under UOG Professor Tom Schils.

Locating the Cocos Lagoon population was achieved by UOG Marine Technician II Johnathan A. Perez, who grew up seeing them at his aunt’s house in Malesso.

“The only way we found the populations is through people who have lived here their whole lives,” said Anthony. “They knew they were here, but they hadn’t been scientifically documented. We owe finding these populations to our friends who helped us and grew up here.”

Heagy said that she is grateful for being able to study in an environment that has been encouraging when it comes to conducting research.

“This is the perfect place to do this work,” said Heagy. “There are so many resources and we’re so lucky to be here. Guam gives you so many resources and so many questions to ask and so many things to think about. The marine laboratory and EPSCoR have given us so many opportunities to ask questions.”

Musicians connect with community at G3 Makerspace

Born and raised in Guam, Peter “Håle’” Cruz grew up listening to classic rock and eventually transitioned into creating reggae music. For five years, he played with local island band Table for Five. Upon moving stateside, Cruz joined Tribal Theory, a reggae group, and toured the United States, Guam, and Hawai’i. After departing Tribal Theory in 2019, he formed Håle, which focuses on Marianas reggae music and draws inspiration from the CHamoru culture and Guam.

Shiabe “Bok” Pangelinan grew up in Yigo in a musically talented family. The son of the late Frank “Bokonggo” Pangelinan, a traditional CHamoru musician, Pangelinan played the local music scene with D.U.B. and Soul Vibes. Much of his music is inspired by his CHamoru heritage and culture.

Two Guam-grown musicians talked story about their roots and culture as part of the second installment of the Guam Green Growth Makerspace’s “Seed Talk Sessions,” a series of developmental opportunities offered by the facility in which industry professionals engage island community members to stimulate creativity and encourage local entrepreneurship. The event took place at the facility’s innovation hub in the CHamoru Village on July 1, 2022.

During their presentation at the G3 innovation hub, Cruz and Pangelinan shared guidance on how to be a successful musician on Guam. They discussed earning royalties, distribution, and general tips about the music industry.

“I wanted to talk about the life and the struggle of being someone who left Guam and trying to make it happen for themselves,” said Cruz. “I think that’s really important. If it wasn’t for that part of my life and being with the CHamoru community here, I don’t think I would be here.”

When asked about what advice they would give to aspiring musicians, Cruz and Pangelinan said to be driven and take risks when you can.

“Whenever you play, keep in mind that you don’t know who’s going to be in that crowd,” said Pangelinan. “It can be the worst gig, but you shouldn’t dismiss them. I’d play in random bars and people would ask me for my number and I’d have a better gig set up. A lot of the times people are scared, but when you push yourself to a point where you know what’s going to happen, it’s going to happen. You can’t second guess yourself.”

Math students present research on coral reef dynamics

Students from the Guam NSF EPSCoR 2022 Summer Math Research experience presented this summer as part of the 2022 Summer Joint Math Research Program showcase held on July 15.

The Summer Math Research Experience was held in conjunction with two other research programs: the Young Research Experience in Mathematics and the National Research Experience for Undergraduates Program. — Students from the Guam NSF EPSCoR 2022 Summer Math Research experience presented this summer as part of the 2022 Summer Joint Math Research Program showcase held on July 15. The Summer Math Research Experience was held in conjunction with two other research programs: the Young Research Experience in Mathematics and the National Research Experience for Undergraduates Program.

During the program, the students were split into two teams to focus on two projects. The first group looked at whether rising sea surface temperatures were a bigger threat to Acropora pulchra and Porites populations than crown-of-thorns starfish, which prey on stony coral. Outbreaks of these starfish can cause severe damage to coral reefs over just a few weeks.

The second group focused on how two different coral species - Acropora pulchra and Porites massive - react in situations of bleaching and disease along with how the presence of seaweed inhibits their ability to recover.

“Being in this program has been pretty amazing and eye-opening,” said Ernie Samelo, an undergraduate mathematics major at the University of Guam. “I’ve learned a lot of stuff about math and applying it in real life and coral. Corals are something I never thought would have so many layers to it. I’ve loved every moment of this program.”

Six students presented their research about the effects of coral bleaching, coral diseases, rising temperatures, and controlling crown-of-thorns (COTS) starfish populations using mathematical modeling this summer as part of the 2022 Summer Joint Math Research Program showcase held on July 15. The students – five undergraduate students and one high school student – were part of the 2022 Summer Math Research Experience held from May 23 to July 16 at the University of Guam.

The program was part of the Guam Ecosystems Collaboratorium for Corals & Oceans (GECCO) project, funded by the university’s Guam NSF EPSCoR grant.

“You’ve inspired research by what I have seen from the titles of your projects,” said Austin Shelton, the director of the UOG Center for Island Sustainability and Sea Grant, during the showcase’s opening remarks. “These are the kinds of things the community needs to understand our coastal and terrestrial resources.”

The Summer Math Research Experience was held in conjunction with two other research programs: the Young Research Experience in Mathematics and the National Research Experience for Undergraduates Program.

Using data collected from researchers at the UOG Marine Laboratory, the models were developed to use as a tool to forecast changes in the island’s coral reefs.

“Creating these mathematical models is important so that we can see and predict the changes from these environmental situations,” said UOG Assistant Professor Mathematics Jaeyong Choi, one of the program’s mentors. ”Using the mathematical models, we can use them to simulate situations based on the data collected from the researchers at the marine laboratory.”

“Applying math to science feels like you’re exploring,” said Siwen “Lulu” Shao, a high school student at St. John’s Catholic School. “You never encounter the same problem. When we built this complex mathematical model, all you have to do is change numbers and parameters and this model would be able to apply to any COTS and any coral relationship in the world.”

The second group focused on how two different coral species – Acropora pulchra and Porites massive – react in situations of bleaching and disease along with how the presence of seaweed inhibits their ability to recover.

Five students join summer math program

Five students have been welcomed to the 2022 Summer Math Research Experience, a six-week research program from May 13 to July 26, 2022 that will have students study mathematical models of coral reef responses to climate change.

During the program, students will gain experience with industry-standard software, network with participants in other summer research programs, and develop skills in oral presentations and technical reports.

“I’m looking forward to this experience because this will be my first time being in a research program,” said Ernie Samelo, an undergraduate in mathematics. “I want to experience everything and apply what I’ve learned in math to this research.”

In addition, the program welcomed two research assistants who will assist the GECCO students along with those who are participating in other concurrent summer math programs such as the National Research Experience for Undergraduates Program.

“I look forward to learning from everyone and I hope everyone can learn from me,” said Cabrini Aguon, an undergraduate in mathematics. “It’ll be a mutual exchange of growth throughout this process.” Over the course of the program, the students will use data collected from the Common Garden Project, a four-year EPSCoR-funded study launched last year that will examine three habitat-forming coral species over a multi-year span and their responses to environmental change.

“Math is the language of nature. You can describe the processes of nature using mathematical models,” said UOG Associate Professor Bastian Bentlage. “If you have a good model, you can identify certain key parameters that are important for corals’ response to stress, and you can make informed decisions about reef management planning and intervention strategies.”

G3 Makerspace workshops inspire community to live sustainably

Guam Green Growth Education Coordinator Abby Crain and Joseph Certeza, the G3 Circular Economy Makerspace Assistant have been holding workshops at their facility in the CHamoru Village since March. At the G3 Makerspace, participants can make jewelry out of bamboo, make pouches out of fused plastic bags, and print on fabric with marine debris.

One of the workshops that are being offered at the G3 Makerspace involves eco-printing, which encourages participants to press patterns on a fabric using foliage that has been collected.

After a print has been made, the fabric can be turned into pouches the participants can keep.

The facility also teaches participants how to process locally harvested bamboo.

The bamboo can then be turned into vases, candle votives, bangles, and earrings.

From making pouches out of repurposed plastic to bamboo bracelets and earrings, the Guam Green Growth Circular Economy Makerspace and Innovation Hub has been encouraging the island’s community to live a more sustainable lifestyle by taking advantage of the resources around them.

The G3 Makerspace and Innovation Hub started holding workshops at their location in Hagåtña’s CHamoru Village in March and has offered courses that involve fusing plastic bags together to make pouches, dyeing fabric with natural pigments found on the island, and processing locally harvested bamboo into vases, bangles, and earrings.

The workshops engage the community in the circular economy, which eliminates waste by promoting the continual use of products. In addition, the workshops also encourage its participants to think of ways to address invasive species such as bamboo and turn them into resources they can use.

Bamboo is an invasive species on Guam because it clogs riverways and causes erosion when bunches of it are ripped from the ground during a storm.

“Right now, we’ve been teaching them how to make jewelry pieces, but we want to expand and teach our community how to utilize bamboo as a source of lumber,” said Joey Certeza, the G3 Circular Economy Makerspace Assistant. “We want to learn how to work with our land and how to utilize the resources it offers us.”

In May, the makerspace will offer workshops that will use malt bags donated from local breweries to make bucket hats and tote bags.

Additional upcoming workshops include printmaking courses in which participants can use marine debris to print on a fabric that can be made into pouches and leather workshops.

“The reception from our participants has been really good,” said Abby Crain, the Guam Green Growth Education Coordinator. “We’ve had couples who do it for a date night, families that come and bring their teenagers with them, and there is this one lady who has done almost every workshop and she’s been a repeat client.”

Certeza says that he enjoys facilitating the workshops because it gives him an opportunity to make connections within the community.

“The kind of experience I’ve been striving to provide while working with Guam Green growth is for the community to realize that engaging in a sustainable lifestyle is easier than you think,” said Certeza. “I want our community to realize the capacity of what they can do with their hands and their minds with the resources the island provides for us.”

Workshops at the G3 Circular Economy and Innovation Hub are $20 and above and are held on Thursdays and Saturdays.

For more information about upcoming workshops, please visit the facility’s events page.

The Guam Green Growth Circular Economy Makerspace and Innovation Hub is funded in part by Guam NSF EPSCoR.

Mónica Feliú-Mójer speaks with Guam Science and Technology Steering Committee

During a meeting on April 4th, 2022, members of the Guam Science and Technology Steering Committee met with Mónica Feliú-Mójer. Feliú-Mójer is the director of communication for Ciencia Puerto Rico, a nonprofit organization that advocates for science in Puerto Rico and supports Puerto Rican researchers to empower communities to improve their lives and society.

Feliú-Mójer also works with Science Communication Lab, a nonprofit that uses multimedia storytelling to communicate science to the public, as its director of diversity and communication training.

“I like to push back on this idea that our communities are not scientifically literate. They know science. There’s a lot of community and ancestral scientific knowledge,” said Feliú-Mójer. “I think it is important that we have a conversation about scientific literacy and how people can use it to benefit their life.”

The steering committee consulted with Feliú-Mójer learn about how to put science in service of communities.

As part of her work with Ciencia Puerto Rico, Feliú-Mójer facilitates Aquí Nos Cuidamos (“Here We Take Care of Each Other”), a community-centered multimedia toolkit that provides culturally relevant resources to marginalized communities in Puerto Rico on how to respond to the COVID-19 pandemic. The program has produced resources such as guidelines, checklists, and infographics; audio broadcasts to remote areas; and videos with sign language.

“I think one of the things that’s really important to me when it comes to engaging different communities with science is that fundamentally, science is about solving problems,” said Feliú-Mójer. “Everybody has problems. Science equips us with tools to solve problems regarding such determining whether something is true on social media or making a decision about our finances or healthcare.”

Feliú-Mójer said that communicating science in a culturally relevant way makes science more accessible for audiences.

“Culturally relevant science allows people to see themselves in science. It makes science more welcoming. A lot of people see science as a subject they need to take in school and not much more and part of what I want to do is change that. I want people to see science as a tool that can serve them no matter who they are,” said Feliú-Mójer.

2022 Student Research Experience: Meet our Student Participants!!

This year, Guam NSF EPSCoR welcomed 10 undergraduate students from the University of Guam to its Student Research Experience. From coastal oceanography to red algae ecology and diadromous genomics, the internship offers mentorship and research training to increase the diversity of students who choose STEM careers and teach them skills such as DNA extraction and sequencing, experimental design, and more. In this article, we will introduce five out of the 10 students who have joined the program.

Jacquelyn Cabusi, a pre-pharmacy and bio-medical track double major, joined the program to gain experience conducting research. Under the mentorship of Atsushi Fujimura, a UOG professor of oceanography, Cabusi will focus on analyzing concentrations of toxic chemicals in Guam’s marine environments during and after the SARS-CoV-2 pandemic and how they impact coral health. One of the chemicals that will be included in the study is oxybenzone, which can be found in products like sunscreen and certain cosmetics and can negatively affect coral health.

“What I really enjoy about EPSCoR is that it’s allowing me to explore options and paths that I could possibly take,” said Cabusi. “Throughout my time here in EPSCoR, the primary thing I would like to learn is the reason why I applied – which is to learn more about the processes that surround conducting a research study. I’m excited to construct my own experimental design and carry it out, as well.”

—

This is not the first time that Anela Duenas, a biology major, has participated in a STEM research program. Her time as a 2021 NSF INCLUDES: SEAS Islands Alliance research fellow led her to become interested in the Guam NSF EPSCoR Student Research Experience as an opportunity to further enhance her research knowledge and build relationships with her mentor and peers.

Under the mentorship of Tom Schils, a UOG professor of marine biology, she is working on the experimental design of her research project, which will focus on studying crustose calcifying red algae (CCRA). CCRA is a group of marine algae that deposit limestone like stony corals.

After earning an undergraduate degree, Duenas plans to pursue higher education to eventually return to the Marianas and continue answering questions about the region’s marine ecosystems.

“After graduate school, I plan to come back to the Marianas – more specifically Saipan because that’s where I’m from – and I want to conduct some research and hopefully help open the first marine lab there,” said Duenas.

Hunter Sidell got to know his mentor, Daniel Lindstrom, when he volunteered to help the UOG professor of biology collect specimens in 2021. Sidell has always been interested in the field of biology and finds his background as a philosophy major to be helpful when it comes to conducting research as it encourages him to be curious to find answers about the world around him.

Under Lindstrom’s mentorship, Sidell’s research will involve learning more about the island’s native diadromous shrimp species. Diadromous animals are those that transition between freshwater and saltwater environments at different stages of their life cycles. Animals that are diadromous on Guam include certain species of fish, shrimp, and snails.

“Dr. Lindstrom’s amazing. I knew that he would be a great mentor when he bought me pizza,” Sidell said. “I’d always ask a lot of questions and he never got impatient. In fact, it seemed like he was always happy to answer my questions and it created this sort of dialogue where he wanted to answer all of my questions and I wanted to keep on asking them so I could learn more. There’s nothing more I could ask for. I hope I can continue working with him.”

Antoni Badowski 2022 SRE scaled — Antoni Badowski

Antoni Badowski, a biology major, joined the SRE program to gain research experience and apply what he’s learned in his classes to conducting research.

Badowski, who has always been fascinated with the natural world, says that being mentored by Daniel Lindstrom has been a great experience. Under the mentorship of Lindstrom, Badowski is excited to learn more about the diadromous animals that are native to Guam.

“I am most excited to meet and work with other people who are passionate about the natural world,” Badowski said. “I’m also excited to explore and find out my areas of interest and career fields to get know more of what I can do in the future and what I can accomplish.”

Zaine Benavente 2022 SRE scaled — Zaine Benavente

Zaine Benavente, a biomedical track major, saw the SRE program as a way to gain experience and become more familiar with the lab procedures he would conduct in his classes.

“I just finished my genetics class and I was thinking that I could get more experience here because we had been doing a lot of extractions and procedures in the lab and I wondered if it would be similar,” said Benavente. “And it is quite similar! Now, I’m applying what I’ve learned in the classroom to my internship.”

During the program, Benavente has been performing DNA extractions of coral samples as part of his work with David Combosch, a UOG professor of population genetics. Combosch’s research explores evolutionary questions in island settings using genetic and genomic approaches to inform coral reef conservation, management, and restoration.

“As one of my career goals, I always told myself that I wanted to be a medical lab technician,” said Benavente. “But now that I’m in a STEM program, I get to explore and pick the brain of my advisor about what it’s like to be a researcher.”

Study explores effects of nutrient pollution on Guam reefs

The coral samples were exposed to varying levels of ammonium and will monitor how the corals respond over time. Ammonium is a chemical form of nitrogen that can be present in marine ecosystems.

Fisher and Dodds collected samples of staghorn coral from West Agana and the Luminao Reef in Santa Rita. The sites were chosen due to their different levels of human activity. Substances such as fertilizer, stormwater runoff, and sewage treatment plant discharge can cause nutrient pollution.

Molly Fisher, a graduate student from Kansas State University, visited the University of Guam last month to study the effects of nutrient pollution on the island’s coral reefs.

Walter Dodds, a distinguished professor from Kansas State University, visited the University of Guam along with Fisher to help conduct the experiment as part of the first academic cross-collaboration between Kansas NSF EPSCoR and Guam NSF EPSCoR.

Warming waters, diseases, and sedimentation are some stressors that threaten the health of coral reefs. To help preserve these important ecosystems, a researcher from Kansas State University visited the University of Guam and studied a stressor that has not been well-explored — the effects of nutrient pollution on corals found in Guam waters.

Nutrient pollution is caused by excess nitrogen and phosphorous in the air and water and can damage the environment, cause health problems, and take a heavy toll on the economy.

Molly Fisher, a graduate student from Kansas State University, arrived on Guam on March 14 as part of the first academic cross-collaboration between Kansas NSF EPSCoR and Guam NSF EPSCoR.

She came along with her advisor, Walter Dodds, a distinguished professor from KSU. Dodds’ research areas of specialization focus on water quality and nutrient cycling. He departed Guam on March 18.

Dodds and Fisher collected small samples of staghorn coral (Acropora pulchra), one of Guam’s dominant reef-builders, from West Agana and the Luminao Reef in Santa Rita.

The sites were chosen due to their different levels of human activity. Substances such as fertilizer, stormwater runoff, and sewage treatment plant discharge can cause nutrient pollution.

“Luminao is our pristine site while West Agana has roads and a sewage treatment plant that may contribute to increased levels of nitrogen in the water,” said Dodds. “We add nitrogen and phosphorous to get our plants to grow. If you add too much fertilizer, the system gets too productive for its own good. In the case of corals, that means that algae can grow over the surface of the coral and cause them to stress and die.”

Fisher said that the coral samples were exposed to varying levels of ammonium and will monitor how the corals respond over time. Ammonium is one form of nitrogen that can be present in marine ecosystems.

“Anthropogenic nutrient loading is a stressor to corals that isn’t heavily studied,” said Fisher. “Our work is pretty novel, and we hope that we can figure out how they respond to nutrient loading in an attempt to hopefully lessen the impacts on corals.”

Dodds said that the faculty and staff at the University of Guam Marine Laboratory have been integral to the execution of the project.

“We’re grateful for the faculty here at the University of Guam. They’ve been extraordinarily helpful and have gone out of their way to make us feel welcomed and find the materials that we need to do this work,” said Dodds. “Everyone has been super helpful and told us that if we need anything at all, that we can talk to them. It’s been an incredibly pleasant experience so far.”

Fisher concluded the experiment and departed Guam on April 10.
