With Discovery of Roundworms, the Great Salt Lake Ecosystem Just Got More Interesting

Scientists have long suspected nematodes, commonly known as roundworms, inhabit Utah’s Great Salt Lake sediments, but until recently, no one had actually recovered any there.

Scientists have long suspected nematodes, commonly known as roundworms, inhabit Utah’s Great Salt Lake sediments, but until recently, no one had actually recovered any there.

It took a University of Utah postdoc with a hammer and loads of field experience to solve the puzzle. Along with biology professor Michael Werner, postdoctoral researcher Julie Jung announced in a study published Tuesday that they discovered thousands of tiny worms in the lake’s microbialites, those reef-like structures that cover about a fifth of the lakebed.

Their initial attempts failed to find nematodes in lakebed sediments, prompting Jung to take a hammer to samples of microbialites where she struck biological pay dirt. Breaking up the carbonate structures yielded thousands of nematode specimens representing several species, resulting in a significant discovery.
