Discovery of a New Nematode Species in Great Salt Lake
SALT LAKE CITY — A recent study has revealed an exciting discovery in the Great Salt Lake. Researchers have found a new type of nematode, called Diplolaimelloides woaabi. This tiny roundworm differs from many other known nematodes.
The findings, published last month in the Journal of Nematology, follow earlier work by University of Utah biology professor Michael Werner and his team. They confirmed the presence of nematodes in the lake, which had been suspected for years.
The new species, measuring less than 1.5 millimeters, is unique in its characteristics, making it just the second known nematode species inhabiting environments outside of oceans. These nematodes usually thrive in salty conditions like those found in coastal areas.
In a nod to the area’s cultural heritage, the researchers collaborated with local Native American leaders. The name “wo’aabi,” meaning “worm” in the Shoshone language, honors the Northwestern Band of the Shoshone Nation, whose ancestral land includes the lake.
While brine shrimp and brine flies are commonly recognized as part of the lake’s ecosystem, the role of nematodes remains largely unknown. The researchers noted that Diplolaimelloides woaabi may serve as an important bioindicator of ecological change in the lake.
There are two leading theories about how this new species ended up in the Great Salt Lake. One suggests they are remnants from a prehistoric past when this region was part of a vast marine waterway. Byron Adams, a biology professor at Brigham Young University, explains that ancient rivers and streams would have created suitable habitats for these organisms.
The second theory posits that these nematodes may have hitchhiked on the feathers of birds migrating between South America and the northern regions. While this idea sounds unlikely, it highlights how interconnected ecosystems can be.
In addition to these fascinating findings, recent studies showcase the Great Salt Lake’s declining water levels due to climate change. This decline severely impacts the local ecosystem and raises concerns about the species that depend on it.
Overall, this discovery invites further research into the unique species inhabiting the Great Salt Lake and the ecological impacts of changing environments. For more detailed insights and data, you can find the study here.
