With the help of new technologies, a team led by the University of Washington has confirmed that piranhas — and their plant-eating cousins, pacus — lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.
A University of Washington team inspired by the clingfish’s suction power set out to develop an artificial suction cup that borrows from nature’s design. Their prototype actually performed better than the clingfish.
Three University of Washington graduate students are among this year’s recipients of a prestigious NASA fellowship that funds student research projects in the fields of Earth and planetary sciences and astrophysics.
An international team led by the UW and Stanford has created a framework for how city planners and municipalities around the world can start to measure the mental health benefits of nature and incorporate those into plans and policies for cities and their residents.
Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep — about 100 to at least 500 feet below the surface — little to no light breaks through. Researchers must rely on submersible watercraft or sophisticated diving equipment to be able to study ocean life at these depths, known as the mesophotic zone. These deep areas span the world’s oceans and are home to extensive coral…
An ample buffet of freshwater food, brought on by climate change, is altering the life history of one of the world’s most important salmon species.
A collaborative group led by the University of Washington has released a set of research papers, fact sheets and modeling tools to help agencies incorporate traditional knowledge and human dimensions into Pacific herring management.
Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska’s most productive salmon populations, and the fisheries they support, depend on the entire watershed.
Just over one-third of the world’s 246 longest rivers remain free-flowing, according to a new study published May 8 in Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe.
Lifelong chemical records stored in the canine teeth of an elusive group of harbor seals show that the seals remain in freshwater their entire lives and are likely a distinct population from their relatives in the ocean. Their home territory, Iliamna Lake, is in the heart of the proposed Pebble Mine project.
A team of UW students hopes to make it possible to accurately predict peak bloom timing for the iconic Quad cherry trees.
Researchers have developed a new approach to map huckleberry distribution across Glacier National Park that uses publicly available satellite imagery. Tracking where huckleberry plants live now — and where they may move under climate change — can help biologists predict where grizzly bears will also be found.
As gray wolves return to eastern Washington, a new study finds that one species of deer is changing its behavior to spend more time away from roads, at higher elevations and in rockier landscapes.
The iconic cherry trees in the University of Washington’s Quad will likely reach peak bloom the third week of March, right in line with most years.
New research by the University of Washington and U.S. Geological Survey suggests many lakes pose little threat to global carbon levels, at least for now.
New research shows that the powerful sense of smell Pacific salmon rely on for migration, finding food and avoiding predators might be in trouble as carbon emissions continue to be absorbed by our ocean.
Russell Callender began as Washington Sea Grant’s new director this fall, and UW News sat down with him recently to learn more about what he hopes to bring to the organization.
The University of Washington Climate Impacts Group and regional tribal partners have developed a collection of resources that may be useful to tribes at any stage in the process of evaluating their vulnerability to climate change. The project is a partnership among tribes, tribal associations, universities and the federal government.
Massive wildfires, which may be getting more intense due to climate change and a long history of fire-suppression policies, have strikingly unequal effects on minority communities, a new study shows.
A new University of Washington initiative seeks to advance research on the health benefits of time spent in nature, connecting academic researchers with pediatricians, childcare providers, mental health practitioners and others who work with various populations on critical health issues.
In a 20-year study, UW researchers and colleagues have found that nearly 600,000 pounds of sockeye salmon carcasses tossed to the left side of a small, remote stream in southwest Alaska, helped trees on that side of the stream grow faster than their counterparts on the other side.
A new study led by the University of Washington found that while dead whales are valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers.
A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. The paper shows that the footprint of bottom-trawl fishing on continental shelves and slopes across the world’s oceans often has been substantially overestimated.
Former Interior Secretary Sally Jewell brings a lifetime of experience in business, nonprofits, government and the outdoors to the University of Washington, where one of her tasks is to help shape the future of EarthLab, a new university-wide institute that seeks to connect scholars with community partners to solve our most difficult environmental problems.
University of Washington researchers have found policies are shifting toward restoration projects that include input from more groups and offer a range of benefits to Puget Sound, including flood control, salmon recovery, recreation and habitat protection.
A team led by the University of Washington has created an environmentally friendly way to remove color from dyes in water in a matter of seconds.
Anchovies, herring, sardines and other forage fish play an essential role in the food web as prey for seabirds, marine mammals and larger fish like salmon. When ground into fishmeal and oil, they are also a key food source for farmed seafood and land-based livestock such as pigs and poultry. As seafood consumption outpaces the growth of other food sectors and continues to grow worldwide, farmed seafood — also called aquaculture — has increased rapidly to meet consumer demand. That…
A new study led by the University of Washington considers which food type is more environmentally costly to produce: livestock, farmed seafood or wild-caught fish.
A new University of Washington-led paper pinpoints starvation as the cause of death for hundreds of thousands of Cassin’s auklet seabirds in late 2014 to early 2015.
Astronauts at the International Space Station are spending more time away from Earth, but they still need their daily serving of vegetables. In the quest to find a viable way for crew to grow their own veggies while orbiting — and possibly one day on the moon or Mars — student researchers are sending broccoli seeds coated with a healthy dose of probiotics to space. Watch the May 21 launch Six broccoli seeds were aboard the Orbital ATK Cygnus spacecraft…
A Q&A with retiring Washington Sea Grant director Penny Dalton on her drive to serve the public, and the ways in which she has helped young marine policy experts get started in the field.
The World Register of Marine Species has named the Mariana snailfish one of its 10 “remarkable new species” discovered in 2017. The team that discovered and named the small fish includes Mackenzie Gerringer, a postdoctoral researcher at the UW’s Friday Harbor Laboratories.
A new trail that winds through Washington Park Arboretum is bringing to focus plants previously hidden and a stream that used to be underground in pipes and culverts. The UW together with Seattle Parks and Recreation and the Arboretum Foundation on Sunday, April 8 will celebrate the trail opening with festivities along the path.
A University of Washington-led project spanning countries, years and institutions has attempted to reconstruct what the southern end of the world looked like during the Triassic period, 252 to 199 million years ago.
The largest and oldest Chinook salmon — fish also known as “kings” and prized for their exceptional size — have mostly disappeared along the West Coast, according to a new study led by the University of Washington.
With snow falling in the Puget Sound region this week, it’s hard to imagine cherry trees in bloom. But assuming temperatures return to normal soon, this year’s cherry blossoms are on track for a typical bloom season. Full bloom is expected the week of March 19.
Reductions in sea ice in the Arctic have a clear impact on animals such as polar bears that rely on frozen surfaces for feeding, mating and migrating. But sea ice loss is changing Arctic habitat and affecting other species in more indirect ways, new research finds. Beluga whales that spend summers feeding in the Arctic are diving deeper and longer to find food than in earlier years, when sea ice covered more of the ocean for longer periods, according to…
A team of ecologists and economists is the first to test whether real-life ecological interactions produce economic benefits for the fishing industry. The results were published online Jan. 29 in the Proceedings of the National Academy of Sciences.
The University of Washington joins 12 other leading North American research universities in the new University Climate Change Coalition, or UC3, a group committed to leveraging its research and resources to help communities accelerate climate action.
