The ice worm is one of the largest organisms that spends its entire life in ice and Washington State University scientist Scot Hotalilng is one of the only people on the planet studying it.
He is the author of a new paper that shows ice worms in the interior of British Columbia have evolved into what may be a genetically distinct species from Alaskan ice worms.
Hotaling and colleagues also identified an ice worm on Vancouver Island that is closely related to a separate population of ice worms located 1,200 miles away in southern Alaska. The researchers believe the genetic intermingling is the result of birds eating the glacier-bound worms (or their eggs) at one location and then dropping them off at another as they migrate up and down the west coast.
“If you are a worm isolated on a mountaintop glacier, the expectation is you aren’t going anywhere,” said Hotaling, a postdoctoral biology researcher. “But lo and behold, we found this one ice worm on Vancouver Island that is super closely related to ice worms in southern Alaska. The only reasonable explanation we can think of to explain this is birds.”
