In a new study, NOAA Fisheries scientists, in partnership with the University of Alaska Fairbanks, show that it is possible to estimate fish biomass for more than one species at the same time, using environmental DNA (eDNA).
NOAA Fisheries has awarded more than $9.2 million in grants funded by the Inflation Reduction Act to academic partners that will help recover threatened and endangered Pacific salmon.
When research scientist Gary Longo first saw the results of his genomic analysis of sardines, he thought he must have mixed up his samples.
The world’s freshwater lakes are freezing over for shorter periods of time due to climate change. This shift has major implications for human safety, as well as water quality, biodiversity, and global nutrient cycles, according to a new analysis from an international team of researchers.
An international coalition led by Oregon State University scientists concludes in its annual report published this month that the Earth’s worsening vital signs indicate a “critical and unpredictable new phase of the climate crisis” and that “decisive action is needed, and fast.”
In a recent review, a panel of scientists said the Northwest Power and Conservation Council’s Fish and Wildlife Program for the Columbia River basin is still changing and progressing after 40 years of implementation, but will need further updates and improvements, including a better strategy for incorporating climate change into the Program and a more comprehensive analysis of the outcome of removing the four lower Snake River dams.
Dwindling snowpack, rising sea levels and dangerous heat events are among climate change challenges Washington state agencies are planning for under the guidance of a new “climate response” strategy.
Some of the butterflies most in danger of fluttering out of existence fare better when their habitats are actively managed by humans, a recent study found.
Competition with millions of pink salmon in the North Pacific Ocean, which are known for their two-year cycle of abundance, is resulting in shorter steelhead returning to the Snake River – also on a two-year cycle, according to a recent study.
Removing the Elwha and Glines Canyon dams on Washington's Elwha River presented an opportunity to study the ecological response of a river ecosystem to large-scale disturbance and subsequent restoration.
A regional panel of scientists’ recent review of the Upper Snake River Tribes Foundation’s assessment of spring/summer Chinook losses resulting from the construction of upper Snake River dams said the Tribes’ analysis could be improved and gives pointers to help with a second round of work.
Greenhouse gas concentrations, the global temperature across land and oceans, global sea level and ocean heat content all reached record highs in 2023, according to an international State of the Climate report led by NOAA scientists.
New research from the U.S. Geological Survey links wildfires to increased mercury concentrations in Pacific Northwest headwater streams.
Northern California steelhead require continued protection as a threatened species under the federal Endangered Species Act, according to a recent 5-year review by NOAA Fisheries.
Since 2006, a fast-moving disease known as white-nose syndrome has killed an estimated 6.7 million bats, wiping out entire colonies and decimating creatures that provide an integral means of pest control.
During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new Oregon State University study found.
A bird that spends its entire life near mountaintops in the Pacific Northwest is likely to become in danger of extinction as a result of climate change, the U.S Fish & Wildlife Service has announced.
Gray whales that spend their summers feeding in the shallow waters off the Pacific Northwest coast have undergone a significant decline in body length since around the year 2000, a new Oregon State University study found.
A new research project led by the University of Montana’s Flathead Lake Biological Station expands the impact of the station’s renowned expertise from mountain watersheds to ocean depths.
Oregon State University researchers found that U.S. adults are fairly confident in linking wildfires and heat to climate change, but less confident when it comes to other extreme weather events like hurricanes, flooding or tornadoes.
A new West Coast collaboration for offshore wind science was announced last month. The Pacific Offshore Wind Consortium is a joint effort between three research centers: the Schatz Energy Research Center at Cal Poly Humboldt, the Pacific Marine Energy Center at Oregon State University, and the Center for Coastal Marine Sciences at Cal Poly San Luis Obispo.
New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range.
A 15-year period ending in 2020 that included a marine heat wave and a sea star wasting disease epidemic saw major changes in the groups of organisms that live along the rocky shores of the Pacific Northwest.
A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon.
Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species, research by Oregon State University and the U.S. Forest Service has shown.
