Climate change and species invasions raise fears that iconic cold-water species like trout, salmon, and char could be extirpated from most of their ranges this century.
A new study by researchers at the U.S. Forest Service Rocky Mountain Research Station published in Global Change Biology shows that high-resolution stream temperature scenarios can be used to forecast which streams will serve as climate refuges for native cutthroat and bull trout later this century and that many streams are forecast to be too cold to be invaded by non-native species.

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research profile.
The U.S. Forest Service has a long history as a leader in conservation genetics, and this recently took an exciting step forward with the launch of the National Genomics Center for Wildlife and Fish Conservation.
The Forest Service’s wildlife genetics lab, which has been central to the Rocky Mountain Research Station’s conservation genetics program since 1998, has been reorganized and renamed to better reflect the scope of its work nationwide. The Center is a leading edge facility for advanced genomics research, nationally recognized, and works extensively with states, tribes, universities and private groups to address the management issues of over 60 fish and wildlife species.

U.S. Forest Service scientists at the Rocky Mountain Research Station in Missoula, Mont., have identified a new species of fish—the cedar sculpin (Cottus schitsuumsh). Although thousands of new species are described by scientists each year, only a small percentage of them are animal species, and even fewer are found in the United States, underscoring the importance of this discovery.
Freshwater sculpins, with their characteristic large heads and fins, are bottom dwellers that can be found in cold, fast-moving streams throughout North America. Biologists have long suspected that there were undescribed species of sculpins in the Upper Columbia River Basin, but lacked the tools to recognize them. Cedar sculpin populations were previously thought to be shorthead sculpin (Cottus confusus), an understandable misidentification given that sculpins are notoriously difficult to identify based on their physical features.

It’s a wonder that Justin Runyon’s parents didn’t have insomnia. After all, who could sleep when the young bug enthusiast was throwing on floodlights outside the house in the middle of the night to attract and collect insects?
“Yes, my parents were very patient with me,” said Runyon, a research entomologist at the Forest Service’s Rocky Mountain Research Station.
Runyon no longer needs to wake his parents to conduct his research – he has plenty of opportunity to do that at his lab in Bozeman, Mont., where he studies the chemical interaction between insects and plants. His work and accomplishments earned him this year’s prestigious Presidential Early Career Award for Scientists and Engineers. The accolade is the highest honor bestowed by the U.S. Government on science and engineering professionals in the early stages of their independent research careers. Runyon was one of 102 recipients to receive the award this year. Read more »

On the morning of Sept. 11, 2001, sitting in a small Cessna about to go airborne, the pilot suddenly slowed the plane and aborted the takeoff. He said he had received orders that all flights had been grounded and that any airplanes that did not comply would be shot down by the Air Force.
The United States was under attack.
At the time, my job had been with the Arkansas Forest Inventory and Analysis survey program monitoring plots on the Mississippi Delta. I spent the rest of that day tracking my crews working in the field, and like the rest of the world, tried to comprehend the events as they unfolded. Read more »

With wildfires that raged out of control this fire season, a year of “devastating conflagrations” seems to be the only way to describe such massive destruction on the nation’s forested lands. And scientists who know something about limiting the power of these forest infernos are needed more than ever.
Lucky for us, Terrie Benavidez Jain, a U.S. Forest Service scientist, has answers to help reduce the impacts of fire on forested lands. In fact, researching and studying the science of forest fires is something Jain has come to know quite well throughout her impressive career. Read more »
