Researchers who created “family trees” for nearly 10,000 fish found that first-generation, wild-born descendants of hatchery-origin Chinook salmon in an Oregon river show improved fitness.
The Department of Commerce and NOAA have announced plans to allocate $60 million in funding to advance tribal priorities and address the impacts of climate change on Pacific salmon and steelhead in the Columbia River. These funds from the Infrastructure Law will also address deferred maintenance and repairs at Mitchell Act-funded hatchery facilities across the Columbia River Basin.
The famous work ethic of honey bees might spell disaster for these busy crop pollinators as the climate warms, new research indicates.
The escalation of extreme wildfires globally has prompted a critical examination of wildfire management strategies. A new study from the University of Montana reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.
New research indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those areas now.
The California Current ecosystem is a vital ocean system stretching from Washington to Baja California. It is facing a strong 2024 El Niño event, a cyclical warming of the Pacific Ocean. However, the latest information from NOAA’s Integrated Ecosystem Assessment program suggests the ecosystem is better positioned to weather these changing conditions than previous El Niño events.
Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.
Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows.
A new report says that the four lower Snake River dams are not as environmentally friendly as dam advocates tout.
A very mild February wrapped up a record-warm winter for the U.S., according to experts from NOAA’s National Centers for Environmental Information.
Oregon Department of Fish and Wildlife’s fish health lab has detected a novel parasite in sick rainbow trout that were raised at Klamath Falls, Rock Creek and Elk River hatcheries. The detection marks the first time this parasite has been associated with disease symptoms in Oregon's fish.
Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier, according to new modeling led by an Oregon State University scientist.
Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the midwestern United States and Canada.
A new NOAA Fisheries study examined how climate change might affect commercial fishing fleets on the U.S. West Coast, assessing the risk to different bottom trawl groundfish fishing fleets in California, Oregon, and Washington.
Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.
Millions of tons of plastic waste enter the oceans each year. The sun’s ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems.
Hatchery-reared salmon show genetic differences from wild populations in only a few generations, but those differences vary among hatcheries.
The pore-like structure of permeable pavements may help protect coho salmon by preventing tire wear particles and related contaminants from entering stormwater runoff, according to a Washington State University study.
The ocean indicators that NOAA’s Northwest Fisheries Science Center researchers track off Newport, on the Central Oregon Coast, are decidedly mixed for juvenile salmon the coming year. El Niño is still developing at the equator and there are both positive and negative indicators in local waters for emerging salmon.
Oregon State University researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.
Nearly 75 percent of the U.S. could experience damaging earthquake shaking, according to a recent U.S. Geological Survey-led team of over scientists and engineers.
Toxic chemicals produced from oil emissions and wildfire smoke have been found in muscle and liver samples from Southern Resident killer whales and Bigg’s killer whales.
Forests on the west slope of Oregon’s Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought, according to new research by scientists at Oregon State University.
Consistent with direction from President Biden in an executive order to conserve and restore old and mature forests, the U.S. Department of Agriculture has announced a proposal to amend all 128 forest land management plans to conserve and steward old-growth forest conditions on national forests and grasslands nationwide.
Mercury concentrations are twice as high in smallmouth bass found in reservoirs than those in the free-flowing sections of the Snake River in Idaho and Oregon, according to a joint U.S. Geological Survey and Idaho Power Company study that looked at 1,815 specimens of this popular recreational fishing species from a variety of habitats in 31 sites along 530 miles of the Snake River.
