The value of new technology: eDNA and O. mykiss
By Natalie Stauffer-Olsen, PhD. It is always exciting when new technology becomes available that can help us understand, manage and protect wild steelhead, the mavericks of the Pacific salmonids. Steelhead and rainbow trout populations can be difficult to predict, model and understand because of their very plastic (scientific term for highly variable) life histories, from juveniles to…

Many of our…

Using a fossilized slab of rock that formed during the Eocene Epoch…

Using modern genomics to assess thermal adaptation in Lahontan cutthroat trout
Climate change is a major threat to trout and salmon. Their habitat is quickly changing and there will be a lot less of it in the future. But we still don’t have an understanding of if, or how, these cold-water fish might evolve to adapt to a warmer environment. Identifying the genetic basis for any adaptation is…

Fly Fishing on a Changing Yellowstone
Sometimes is takes a crisis to spur action. It's an unfortunate reality—in order to realize that something is dreadfully wrong, something that can't be ignored must first happen. In the summer of 2017, after a low-snow winter in southwest Montana, thousands of native mountain whitefish went belly up on the Yellowstone River between Gardiner and…
