Biology student discovers new algae species in Micronesia
Britney Sison, an undergraduate biology and chemistry student at the University of Guam, has discovered five potentially undocumented diatoms in mud samples from the Micronesian Islands of Palau, Yap, Pohnpei, and the Marshall Islands. Her discoveries are in addition to by UOG student Gabriella Prelosky.
Diatoms are single-celled algae found in oceans, lakes, and rivers. They are primary producers in the food chain as photosynthetic organisms, according to UOG Professor Emeritus of Biology Christopher Lobban, who mentors Sison and Prelosky and runs the Microscopy Teaching & Research Laboratory on the UOG campus.
Sison鈥檚 discovery happened during her research fellowship under 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.
Award-winning poster presentation
She presented on her findings at the 26th International Diatom Symposium, which brought together hundreds of diatom researchers from around the world for the virtual event from Aug. 23 to 25 out of Yamagata, Japan. Her presentation, titled 鈥淣ew species of conopeate Nitzschia in the Pacific Islands,鈥 won third place in the student poster competition.
The species Sison focused on in her presentation were just five of many potentially new species of diatoms she found while examining microbial mat and mud samples.
Diatom samples from Palau, Yap, Pohnpei, and the Marshall Islands were collected and mailed to the UOG lab by interns in the 2021 NSF INCLUDES Bridge-to-Bachelor鈥檚 summer program: Kebang Ngiraklang, a student at the Palau Community College under the mentorship of Vernice Yuki, and Iverson Aliven and Marlin Lee Ling, from the College of Micronesia-FSM under the mentorship of Brian Lynch.
Using the laboratory鈥檚 new Scanning Electron Microscope, which was funded by the university鈥檚 Guam NSF EPSCoR grant, Sison and Lobban were able to examine the samples intensively.
鈥淚t鈥檚 been really interesting to study diatoms,鈥 Sison said. 鈥淚n the words of Dr. Lobban, it鈥檚 like an adult treasure hunt. You never know what you鈥檒l find.鈥
Naming the new species
Sison is now in the process of naming the potentially new species. One of them will be named Nitzschia biseriata because of its unique characteristic of having double rows of pores on its body instead of one.
鈥溾楾wo rows鈥 translated into Latin is 鈥biseriate,鈥欌 Lobban said. 鈥淚f there鈥檚 an obvious characteristic like that, it鈥檚 useful to name it that way because then it will tell people something about the species.鈥
Sison鈥檚 findings will officially be new species once a paper about the diatoms has been peer-reviewed and approved for publication.
Both Sison and Prelosky will present more complete results of their research at the held by the Society for the Advancement of Chicanos/Hispanics and Native Americans in Science from Oct. 25鈥29.
The NSF INCLUDES: SEAS Islands Alliance is administered by the UOG Center for Island Sustainability and Sea Grant programs in partnership with the School of Education at the 91快播. UOG faculty members Austin Shelton, Cheryl Sangueza, and Else Demeulenaere serve as investigators of the grant award. NSF INCLUDES collaborates closely with the program, also funded by the National Science Foundation.
