A recent University of Washington study sought to understand why shark teeth are shaped differently and what biological advantages various shapes have by testing their performance under realistic conditions.

The University of Washington and The Nature Conservancy have created an animated map showing where mammals, birds and amphibians are projected to move in the Western Hemisphere in response to climate change.
Analysis of almost 3,000 pairs of Danish twins shows that they live longer than the general population, especially if they are identical.
Large, carnivorous fish excrete almost half of the key nutrients, phosphorus and nitrogen, that are essential for the survival of coral reefs.
UW professor Adam Summers is scanning and digitizing all 25,000 species of fish that live on Earth. Each species soon will have a high-resolution, 3-D visual replica online, available to all and downloadable for free.
In a three-page commentary in the journal Nature, fisheries professor Ray Hilborn argues that establishing marine protected areas is not as effective at protecting marine biodiversity as properly managing recreational and commercial fisheries.
Scientists from the University of Washington have found evidence that ocean acidification caused by carbon emissions can prevent mussels attaching themselves to rocks and other substrates, making them easy targets for predators and threatening the mussel farming industry.
Ray Hilborn, a UW professor of aquatic and fishery sciences, this week will receive the 2016 International Fisheries Science Prize at the World Fisheries Congress in Busan, South Korea.
In a new study, scientists found that selectively fishing for lingcod in protected areas actually avoided hampering the recovery of other fish, including rockfish species listed as overfished.
Most of the world’s wild fisheries could be at healthy levels in just 10 years, and global fish populations could greatly increase by 2050 with better fishing approaches, according to a new study co-authored by University of Washington researchers.
A University of Washington team won first place in a science communication video contest that culminated during the recent Ocean Sciences Meeting.
Just like a strong financial portfolio contains shares from different companies, the diverse subpopulations of herring from different bays and beaches around Puget Sound collectively keep the total population more stable, a new study finds.
As the Arctic continues to change due to rising temperatures, melting sea ice and human interest in developing oil and shipping routes, it’s important to understand belugas’ baseline behavior, argue the authors of a new paper.
Two University of Washington teams claimed top prizes in a national competition to design a game about climate adaptation.
UW scientists will give free talks on climate change for three consecutive Saturdays at Mt. Baker Ski Area.
The speed of vessels operating near endangered killer whales in Washington is the most influential factor – more so than vessel size – in how much noise from the boats reaches the whales, according to a new study published today in the online journal PLOS ONE.
A new study in Ecology shows that Alaskan Dolly Varden trout, once they reach about 12 inches in length, can retire permanently from going to sea. They rely on digestive organs that can massively expand and contract and a unique relationship with sockeye salmon.
The equipment used to farm geoducks, including PVC pipes and nets, might have a greater impact on the Puget Sound food web than the addition of the clams themselves. That’s one of the findings of the first major scientific study to examine the broad, long-term ecosystem effects of geoduck aquaculture in Puget Sound.
A group of young marine-disease researchers from around the country has contributed key information about sea stars’ immune response when infected with a virus that is thought to cause a deadly wasting disease. It’s the first time researchers have tracked how genes behave when encountering this naturally occurring pathogen, which could help explain how sea stars attempt to fight the virus and why they develop lesions and appear to melt.
A new report published Tuesday documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.
University of Washington researchers have found the types of organisms in Seattle’s Elliott Bay change depending on the shoreline nearby, either armored or restored beaches. Young chum salmon adjusted their diets based on these changes.
University of Washington scientists recently announced the name of a new genus and species of frogfish, which are small, stocky creatures found in most tropical and subtropical oceans around the world.
The Natural Capital Project, with offices at UW, wants to integrate the socioeconomic, cultural and spiritual values of nature into all major decisions affecting the environment and human well-being.
The Ocean Modeling Forum is trying something very rare — bringing together multiple science models and people who care about a particular ocean resource or fishery to decide what’s most important for its vitality and the communities it serves.
A Washington Sea Grant staff scientist is sharing top honors for developing gear that nearly eliminates seabird bycatch in long-line fisheries from the West Coast to South Africa.
A chemical signature recorded on the ear bones of Chinook salmon from Alaska’s Bristol Bay region could tell scientists and resource managers where they are born and how they spend their first year of life.
The Fishery Performance Indicators are the most comprehensive, global tool that considers social factors in addition to the usual biological measures when gauging a fishery’s health.
A new study implicates fishing in the collapse of forage fish stocks and recommends risk-based management tools that would track a fishery’s numbers and suspend fishing when necessary.
A University of Washington scientist is lead author on the first census of all Arctic marine mammals, including whales, walruses, seals and polar bears. The multinational report assesses the current status of these populations and makes recommendations for conservation of these species under climate change.
Two University of Washington professors argue in a Science perspectives article that ecosystem managers must learn to make decisions based on an uncertain future.
Freshwater fish with bellies full of shrews – one trout a few years back was found to have eaten 19 – aren’t as random as scientists have thought.
The number of California blue whales has rebounded to near historical levels and, while the number of blue whales struck by ships is likely above allowable U.S. limits, such strikes do not immediately threaten that recovery.
One of Arizona’s largest watersheds – home to many native species of fish already threatened by extinction – is providing a grim snapshot of what could happen to watersheds and fish in arid areas around the world as climate warming occurs.
Washington state’s newest shellfish hatchery has been named after longtime faculty member Ken Chew.
The Magnuson-Stevens Act is the subject of this year’s Bevan Series on Sustainable Fisheries.
Julia Parrish was one of 12 “champions of change” invited to share their ideas on public engagement in science and science literacy June 25 at the White House.
In the first broad-scale study of its kind, UW led research finds half a dozen regions that could provide some of the Western Hemisphere’s more heavily used thoroughfares for mammals, birds and amphibians seeking cooler environments in a warming world.
The stomach and intestines of certain Dolly Varden trout double to quadruple in size during month-long, salmon-egg-eating binges in Alaska each August. It’s the first time researchers have documented such fish gut flexibility in the wild.
Do changes in the amount of fish caught necessarily reflect the number of fish in the sea? “No,” say UW researchers in a “Counterpoint” commentary in Nature.
Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
