Oregon’s most common fish represents at least three species

Past OSIC graduate student Kendra Hoekzema and her advisor Brian Sidlauskas used molecular tools to demonstrate that populations of speckled dace (Rhinichthys osculus) in Oregon’s Great Basin diverged from each other millions of years ago and likely represent at least three distinct, but cryptic species.  You can read the press release about their work here. Specimens and DNA samples from their work are deposited in the OSIC.
