Biology student discovers two potentially new species from Yap
Gabriella Prelosky, an undergraduate biology student at the 91快播, 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.
鈥淭hey鈥檙e primary producers, so they鈥檙e photosynthetic organisms,鈥 said UOG Professor Emeritus of Biology Christopher Lobban, Prelosky鈥檚 mentor. 鈥淭he other characteristic they have is that they鈥檙e the base of the food chain 鈥 they鈥檙e part of the reason why mangroves are rich areas. In freshwater studies, there鈥檚 been a push to know more about water quality, and diatoms act as water quality indicators.鈥
Prelosky is working in Lobban鈥檚 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, 鈥淚 took a couple pictures and showed it to Dr. Lobban, and he said, 鈥業鈥檝e never seen anything like that before.鈥濃
Lobban sent the pictures to a colleague, who identified the specimen as a member of the genus Gompotheca.
鈥淎t that point, we started thinking that we found something new,鈥 Lobban said. 鈥淭here are only two species in the genus Gompotheca, and they鈥檙e 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鈥檛 that one. The second one doesn鈥檛 even look like it belongs in the same genus.鈥
A few weeks later, Prelosky found the second potentially new species from the same sample.
鈥淒r. Lobban noticed that it looked like a different species,鈥 Prelosky said. 鈥淏ut 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.鈥
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.
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鈥17.
鈥淭he first one is named Gompotheca marciae,鈥 Prelosky said. 鈥淚 talked to my parents about naming them after my two grandmothers: Mary from my dad鈥檚 side and Marcia from my mom鈥檚. They have similar names, so it was easy to combine them.鈥
Prelosky named the second one Campylodiscus tatreauae after Linda Tatreau, her former science teacher from George Washington High School.
鈥淚 named it after her because she鈥檚 been such a helpful person in my journey to marine biology,鈥 Prelosky said. 鈥淚 thought it would be nice to name it after her because without her, I wouldn鈥檛 be where I am today.鈥
