The UOG SACNAS Student Chapter received the award at this year’s SACNAS National Diversity in STEM (NDiSTEM) Conference. The event, a cornerstone in fostering diversity in Science, Technology, Engineering, and Mathematics (STEM), took place in Portland, Oregon.

A total of 48 attendees from UOG participated in NDiSTEM, which stands as the largest multidisciplinary and multicultural STEM diversity event in the United States.

UOG President Anita Borja-Enriquez, DBA, a member of the conference delegation, said, “UOG takes immense pride in our presence at the SACNAS NDiSTEM Conference. This gathering not only strengthens our commitment to fostering inclusivity but also emphasizes the vital role of diverse perspectives in shaping the future of science and innovation.”

Throughout the conference, participants actively attended workshops, showcased their research, and established connections with officials from academia and industry nationwide, creating valuable research and career opportunities.

Another significant achievement was the significant number of student presenters from the UOG delegation. Eighteen student attendees from Guam, representing nearly half of the total UOG delegation, delivered presentations at the conference.

18 students from Guam presented their research and took home these awards:

Co-principle investigator for Education and Workforce Development for Guam NSF EPSCoR, Austin Shelton, PhD, also participated in the conference. He is currently an elected member of the SACNAS National Board of Directors and serves as the faculty co-advisor, along with UOG Associate Professor Cheryl Sangueza, for the UOG SACNAS Student Chapter.

“As we immerse ourselves in the vibrant atmosphere of learning and collaboration at the SACNAS NDiSTEM conference, we are not just attendees; we are catalysts for a more inclusive and equitable future in science. Our presence echoes our university’s dedication to shaping a world where opportunities in STEM are accessible to everyone,” Shelton said.

Britney Sison, president of the UOG SACNAS Student Chapter, said, “I am extremely proud and humbled that SACNAS UOG has received the award. It is a testament to the hard work and dedication of our current as well as previous leaders, members, and advisors who laid a strong foundation for our organization.”

Sison added, “This award means a lot to us, and I hope it inspires future students to continue the mission of SACNAS – to support underrepresented groups in their pursuit of degrees and careers in STEM and to encourage others to bring their culture and whole selves into the process.”

Meanwhile, Sabrina Zhi, vice president of the UOG SACNAS Student Chapter, said the award demonstrates collective support from many past and present UOG students to highlight their resilient attitude towards the advancement of representation for the Pacific Island community. “I hope through this award, SACNAS UOG can continue to inspire and support future generations of Guamanian STEM-ists, as it has done for me,” Zhi said.

Celebrating its 50th year, SACNAS fosters the success of underrepresented Americans – from college students to professionals – in attaining advanced degrees, careers, and leadership positions in STEM. It is the largest multicultural and multidisciplinary STEM diversity organization in the United States, serving more than 20,000 students and professionals.

The attendees participated in the conference through support provided by the Guam NSF EPSCoR and NSF INCLUDES SEAS grants and travel scholarships from SACNAS, Chapter Officer Leadership October Retreat (COLOR), and the Research Corporation of the University of Guam.

NSF Guam EPSCOR students prep for SACNAS Conference

Guam NSF EPSCoR students will be presenting research and representing the University of Guam at the largest diversity in STEM conference in the world later this month.

The SACNAS National Diversity in STEM Conference will be held in Portland, Oregon during the last week of October.

SACNAS, the Society for Advancement of Chicanos/Hispanics and Native Americans in Science, is the largest multicultural STEM diversity program in the United States.

During the conference, the students will attend workshops, present research presentations, and connect with officials from schools nationwide for research experience opportunities.

According to Guam NSF EPSCoR Education Workforce and Development Program Associate Emily Wendte, a total of thirteen students will be representing the University of Guam at the conference.

The group is made up of four students from the graduate research assistantship, five from the summer research experience, and three from the summer math research programs.

Nearly half of the delegation has also been selected to present their research to the over 6000 expected attendees.

The students attending the conference must attend preparation workshops facilitated by the Capacity Building Team from Guam NSF EPSCoR and the NSF INCLUDES SEAS Island Alliance Guam Hub.

Cheryl Sangueza Ph.D, who oversees the student experience with Guam NSF EPSCoR says that the process starts long before the students step foot on the conference floor and is geared to give all students everything they need to represent well.

“Preparation for SACNAS is rooted in ensuring confidence, competence, and excitement to represent our grants, our labs, our university, and our island,” said Sangueza. “In our first SACNAS briefing, we did a meet and greet with the then 25 students to start that comradery and UOG Delegation mindset.”

According to Sangueza, an orientation was also held with family, friends and support-systems of the students to insure ample preparation for students on all fronts.

“We held SACNAS Orientation and family members and support systems were invited and the turnout was great! This was designed to continue generating the excitement, and to share this great experience with families. We showed what SACNAS has to offer, we introduced the delegation and announced who are presenting, and we spoke more about travel expectations,” continued Sangueza.

Along with the student presenters, the University of Guam SACNAS Chapter will also be celebrated at the conference.

“Another cool thing is that the UOG SACNAS Chapter is getting an esteemed SACNAS Chapter of the Year Award,” added Sangueza. “Dr. Austin Shelton and I are co-advisors for the student organization and our EPSCoR and INCLUDES students are both members and a few have served as officers.”

Students are traveling to the conference through support provided by the Guam NSF EPSCoR and NSF INCLUDES SEAS grants and travel scholarships from SACNAS, Chapter Officer Leadership October Retreat (COLOR), and the Research Corporation of the University of Guam.

G3 Makerspace workshop: Crafting new things from discarded plastic

Abby Crain, coordinator of G3 Circular Economy Makerspace and Innovation Hub, shows how discarded plastic bags can be made into wallets, purses, and pouches.

Participants of the plastic fusion workshop at the Guam Green Growth (G3) Circular Economy Makerspace and Innovation Hub create new products from discarded plastic bags.

With the goal of discovering innovative ways to repurpose waste, the Guam Green Growth (G3) Circular Economy Makerspace and Innovation Hub organized a plastic fusion workshop this month at CHamoru Village.

During the workshop, Abby Crain, the coordinator of G3 Circular Economy Makerspace and Innovation Hub, demonstrated techniques to transform discarded plastic bags into wallets, purses, and pouches.

She explained plastic fusion as a process in which plastic sheets are melded together into a pattern using heat. Crain used specific types of plastic bags (#2, #4, or #5) for each project, along with patterns, parchment paper, and a flat iron as a heat source.

Proper heat application is crucial in plastic fusion, so participants were instructed to follow safety precautions, according to Crain.

At the beginning of the workshop, Phil Cruz, the sustainability coordinator at UOG Center for Island Sustainability and Sea Grant, helped participants understand the necessity of finding alternative uses for plastic waste.

Cruz emphasized that plastic waste not only mars the island’s landscape but also contaminates the oceans. Safeguarding the environment is paramount for an island community like Guam, as ocean-bound waste can infiltrate the food chain.

Plastics degrade into microplastics, which are ingested by fish. When these contaminated fish are consumed by other marine animals and humans, microplastics travel up the food chain, posing a threat to ecosystems and human health alike.

Moreover, culturally significant and endangered marine animals like the green and hawksbill sea turtles often mistake plastic bags for food since they resemble jellyfish.

“Not only is it (plastic waste) an eyesore but it also goes into our ocean. As an island community, we must do our utmost to protect our environment,” Cruz said.

While plastic pollution is a common concern in the community, Guam also faces challenges in proper waste management and recycling due to the global collapse of the plastic recycling industry in 2020. Consequently, shipping plastics off the island is no longer viable, according to Cruz.

“Therefore, the island community must find creative solutions,” he added.

The concept of Zero Waste becomes crucial in this context, involving the reduction of landfill waste by being mindful of consumption and waste generation, according to Cruz.

With this in mind, workshops are held at the G3 Circular Economy Makerspace and Innovation Hub to repurpose discarded plastics, shaping them into new and useful items.

Additionally, the hub utilizes precious plastic machines to break down specific plastics and mold them into innovative products.

These initiatives reflect Guam’s commitment to addressing its plastic problem while actively involving the community in sustainable practices.

UOG celebrates third G3 Conservation Corps graduation

The Guam Green Growth (G3) initiative at the University of Guam celebrated the graduation of its third conservation corps cohort on Friday, August 11, at the Sinajana Community Arts Hall.

The innovative workforce development program is designed to prepare the island for the emerging green economy. Launched in collaboration with the UOG Center for Island Sustainability and UOG Global Learning and Engagement in 2021, the G3 Conservation Corps program is a full-time training experience spanning five months each year.

Participants received instruction on a wide range of sustainability topics, covering areas such as agriculture, aquaculture, island beautification, invasive species removal, reforestation, circular economy, ocean conservation, and renewable energy.

The latest batch of G3 Conservation Corps members who successfully completed the comprehensive program include Maria Balbin, Jace Blas, Zeriah Blas, Cassie Bordallo, Michael Herbert, Michael Jude Hernandez, Connor Law, Laura Layan, Javier Mercado, Ciara Taijeron, Michael Torres, and Elisa Rose Padilla.

“We’ve learned a lot here and from all of our partners,” said Balbin, who served as corps crew supervisor.

Also at the graduation, UOG President Anita Borja Enriquez hailed the graduates as conservation corps warriors. “You are a special group of conservation leaders. You represent us as ambassadors to our youth and to members of our community through your experiences…Congratulations! We look forward to seeing you do amazing things.”

Governor Lou Leon Guerrero also commended the graduates. “The 12 of you are very significant to the conservation of our island. You have gone through an experience that we will probably never go through,” she said.

Meanwhile, Austin Shelton, UOG Center for Island Sustainability and Sea Grant director, highlighted the unique experience of the third batch of conservation corps. He said the process prepared the corps for the environmental challenges that are occurring in the region and the rest of the world.

“This season was a little bit different. We had an unexpected typhoon, and we had to do things differently. You got on-the-job training for what is becoming the new reality. Climate change is here, and we are seeing an increasing frequency of storms and rising sea levels,” he said.

Shelton also mentioned the impactful multiplier effect generated by the G3 Conservation Corps program, especially in partnership development. For example, he said the program facilitated the establishment of the G3 Art Corps and the newly formed G3 Kupu Corps collaboration with Kupu, a Hawai’i’-based youth leadership development program, now providing eight additional year-long corps positions in Guam and CNMI.

He also underscored G3’s ongoing commitment to expand the movement. He said current efforts of the program attracted new federal funding, enabling the future development of G3 partnerships across Micronesia and the Pacific.

UOG researcher explores the biodiversity of crabs in the Red Sea and Persian Gulf

The specimens gathered from these expeditions will be placed in the Guam Ecosystems Collaboratorium for Corals and Oceans (GECCO) Biorepository, a physical and cyber warehouse of records and images operated by the Guam NSF EPSCoR program. Pictured here are specimens gathered from the Red Sea.

UOG Curator of Crustacea Robert Lasley went on two research expeditions to conduct biodiversity surveys within the Red Sea and the Persian Gulf.

With support from the King Abdullah University of Science and Technology in Saudi Arabia, Lasley joined a team of biologists and spent two weeks at sea collecting specimens such as crabs, mollusks, and worms from May 3 to May 27, 2023.

During this expedition, Autonomous Reef Monitoring Structures (ARMS) were deployed. ARMS are stacks of plates that mimic the sea floor. They are used to recruit local species over a set period of time to gauge and compare marine biodiversity among habitats, islands, and even ocean basins. Lasley and his colleagues will eventually deploy ARMS in Guam.

During his time in Abu Dhabi from June 16 to June 29, Lasley explored the Persian Gulf with a team of scientists as part of a trip sponsored by Archireef, a Hong Kong-based company that builds 3D-printed reef structures to restore degraded coral reefs.

The specimens gathered from these expeditions will be placed in the Guam Ecosystems Collaboratorium for Corals and Oceans (GECCO) Biorepository, a physical and cyber warehouse of records and images operated by the Guam NSF EPSCoR program.

“I’m really interested in crab biodiversity and biogeography in general,” said Lasley. “The Indo-West Pacific – which includes Guam, the Red Sea, and the Persian Gulf – is this massive biogeographic region and some species are connected throughout it. Any specimens I collect anywhere are good to bring to our collection for comparative material because as we do research, we need to compare specimens from Guam but also specimens from elsewhere.”

Between the two trips, Lasley collected more than 500 specimens, which include around 100 to 200 species of crabs.

“We have already found a new record and, possibly, a new species from the Red Sea,” Lasley said. “We are bound to find more as I examine the specimens more thoroughly.”

UOG grad student explores the small world of meiofauna

Over the course of the workshop, Vega was able to connect with meiofauna experts from around the world as well as learn different collection and sampling techniques for DNA metabarcoding of meiofauna communities around Dauphin Island.

“Being in the workshop was very hard in the beginning, but I got to learn a lot by asking other people how they’d process their samples so by the end of the workshop, I was faster,” said Vega. “As a scientist, I feel like if there’s any new skill I would like to have, I’ll just have to practice and I’ll get better. Learning is infinite and it’s exciting to know that.”

Sarai Vega, a biology graduate student from the University of Guam was one of 13 participants selected worldwide to attend the 2023 Dauphin Island Sea Lab Meiofauna Diversity and Taxonomy Workshop in Alabama from May 10 to May 19, 2023.

Meiofauna are invertebrates that live in both marine and freshwater environments that are small enough to pass through a 0.45 micrometer mesh. They live in between the grains of sand and mud on the seafloor and riverbeds. Copepods, flatworms, and nematodes fall under meiofauna.

Because the meiofauna group is broad, the field remains understudied despite its ecological importance.

“Meiofauna have a high turnover, so they reproduce very fast and they don’t live very long,” said Vega. “Because of this, they are a food source to bigger animals like crabs and sea cucumbers. In turn, those bigger animals are food for other animals. If this group didn’t exist, it would affect that chain.”

Over the course of the workshop, Vega was able to connect with meiofauna experts from around the world as well as learn different collection and sampling techniques for DNA metabarcoding of meiofauna communities around Dauphin Island.

As a Guam NSF EPSCoR Graduate Research Assistant, Vega became interested in researching meiofauna to incorporate it into her thesis project, which focuses on studying the formation of sediment plumes in the Pago Watershed in central Guam and how they affect the island’s environment.

Sediment from soil erosion due to fires and invasive species such as wild pigs and deer can wash into rivers, streams, and bays during rainfall. Once in the water, these plumes of sediment can pollute bodies of water and smother coral reef systems.

“These sediment plumes consist of very fine sediment,” said Vega. “I want to understand what’s happening and how they affect meiofauna.”

Vega said that her experience attending the workshop has benefited her development as a scientist.

“Being in the workshop was very hard in the beginning, but I got to learn a lot by asking other people how they’d process their samples so by the end of the workshop, I was faster,” said Vega. “As a scientist, I feel like if there’s any new skill I would like to have, I’ll just have to practice and I’ll get better.

Visiting scholar talks nurseryfish, megamouth shark research at UOG Marine Laboratory

For the month of February, Guam NSF EPSCoR welcomed Tim M. Berra, Ph.D., a professor emeritus and academy professor at the Ohio State University as a visiting NSF EPSCoR scholar.

Berra is a three-time recipient of Fulbright Fellowships to Australia and has authored over 85 scientific papers and 9 books including Freshwater Fish Distribution and A Natural History of Australia.

In 2001, Berra began a long-term field project studying the life history of nurseryfish (Kurtus gulliveri).

Nurseryfish live in the fresh and brackish waters of Papua New Guinea as well as parts of northern Australia. Males of this species carry the egg cluster on a hook that protrudes over their forehead.

This trip was Berra’s first-time exploring Micronesia and his experiences on Guam will help contribute to a book he is writing about the Pacific.

“One of my primary interests in being here is that I’m working on a book about the peopling of the Pacific,” said Berra. “I’ve been throughout Polynesia, Melanesia, and now Micronesia. I wanted to find some answers. Where did these people come from? How long ago was it? How did they get here and what did they bring with them?”

For his research, Berra connected with several local experts such as Michael Carson, Ph.D., a University of Guam Associate Professor of Archaeology.

During his time on Guam, Berra gave three presentations to UOG Marine Laboratory students and faculty regarding his work studying nurseryfish in Australia, the challenges associated with preserving a rare 15-foot megamouth shark, and the descendants of Charles Darwin.

Regarding his time spent at the UOG Marine Laboratory, Berra expressed his excitement about the research being conducted at the facility.

“I’ve met so many people who are dealing with so many important topics like coral bleaching and restoration as well as how climate change affects marine ecosystems,” said Berra. “This is a lively place and students have such a great opportunity when it comes to the Marine Laboratory and EPSCoR to start their careers and make a contribution to science and society.”
