The small subpopulation of polar bears in Kane Basin were doing better, on average, in recent years than in the 1990s. The bears are experiencing short-term benefits from thinning and shrinking multiyear sea ice that allows more sunlight to reach the ocean surface, which makes the system more ecologically productive.

An international group of scientists has laid out an ambitious global conservation plan for parasites. A related paper led by the University of Washington found that responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

Deep-sea anglerfishes employ an incredible reproductive strategy. Tiny dwarfed males become permanently attached to relatively gigantic females, fuse their tissues and then establish a common blood circulation. Now scientists have figured out why female anglerfishes so readily accept their male mates. Their findings are published July 30 in Science.

Recent honors to University of Washington faculty and staff have come from Architect magazine, the Center for Research Libraries, member states of the Asia-Pacific Economic Cooperation (APEC) and the American Society of Human Genetics.

A 5-year, up to $300 million grant from NOAA establishes the new Cooperative Institute for Climate, Ocean and Ecosystem Studies, a UW-based institute with partners at the University of Alaska Fairbanks and Oregon State University. The institute will lead collaborative, multidisciplinary research and education activities around oceans and climate.

Research projects funded for 2020 by EarthLab’s Innovation Grants Program will study how vegetation might reduce pollution, help an Alaskan village achieve safety and resilience amid climate change, organize a California river’s restoration with tribal involvement, compare practices in self-managed indigenous immigrant communities and more.

University of Washington researchers have discovered that the abundance of tiny microplastic contaminants in Pacific oysters from the Salish Sea is much lower than previously thought.

Recent honors to University of Washington faculty and staff have come from the Council of Educators in Landscape Architecture, the Royal Society of Edinburgh and the World Register of Marine Species.

Any old fish can swim. But what fish can walk, scoot, clamber over rocks, change color and even fight to the death? That would be the frogfish. A talk with Ted Pietsch, UW professor of emeritus of aquatic and fishery sciences, about his latest book, “Frogfishes: Biodiversity, Zoogeography, and Behavioral Ecology”

A new study led by the University of Washington finds dramatic increases in the abundance of a worm that can be transmitted to humans who eat raw or undercooked seafood. Its 283-fold increase in abundance since the 1970s could have implications for the health of humans and marine mammals, which both can inadvertently eat the worm.

Researchers from the University of Washington School of Aquatic and Fishery Sciences have discovered that ocean acidification impacts the ability of some oysters to pass down “memories” of environmental trauma to their offspring.

P. Dee Boersma, a UW professor of biology and director of the Center for Ecosystem Sentinels, is a finalist for the 2020 Indianapolis Prize for conservation, to be awarded later this year by the Indianapolis Zoological Society. Sue Moore, a scientist with the center and a UW affiliate professor of biology and of aquatic and fishery sciences, has won the 2020 IASC Medal, also known as the Arctic Medal, from the International Arctic Science Committee.

Four faculty members at the University of Washington have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 12, are Kyle Armour and Jacqueline Padilla-Gamiño, both assistant professors in the College of the Environment; and Hanna Hajishirzi and Yin Tat Lee, both assistant professors in the College of Engineering.

Satellite tracking of adult females and visual monitoring of polar bears in Baffin Bay show changes from the 1990s to the period from 2009 to 2015. Bears in Baffin Bay are getting thinner and adult females are having fewer cubs than when sea ice was more available.

When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”

Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding, according to a new study led by the University of Washington.

Large, old Chinook salmon have mostly disappeared from the West Coast. A new University of Washington and NOAA study points to the recent rise of resident killer whales, and their insatiable appetite for large Chinook salmon, as the main driver behind the decline of the big fish.

With 2019 on pace as one of the warmest years on record, a new international study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming.

A new experiment by the University of Washington has found that some corals are more likely to eat microplastics when they are consuming other food, yet microplastics alone are undesirable.

The American Association for the Advancement of Science has named six faculty members from the University of Washington as AAAS Fellows, according to a Nov. 26 announcement. They are part of a cohort of 443 new fellows for 2019, all chosen by their peers for “scientifically or socially distinguished efforts to advance science or its applications.”

UW marine scientists are using high-tech tags to record the movements of swordfish — big, deep-water, migratory, open-ocean fish that are poorly studied — and get a window into the ocean depths they inhabit.

A team led by the University of Washington and Stanford University has discovered clues in the environment that help identify transmission hotspots for schistosomiasis, a parasitic disease that is second only to malaria in its global health impact.

A new study finds that the western South Atlantic humpback population has grown to 25,000 whales. Researchers, including co-authors from the University of Washington, believe this new estimate is now close to pre-whaling numbers.

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.

This fall the University of Washington’s annual engineering lecture series will feature three UW engineers and scientists who are working across disciplines to manage the quality and quantity of the food we eat and grow.

After more than 20 years, the UW’s Coastal Observation and Seabird Survey Team, or COASST, is itself the subject of scientific study. Social scientists are studying the program’s success to extract lessons for all citizen science efforts.

Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research by the University of Washington and other institutions.

A new study released July 1 in Nature Climate Change gives hope for coral reefs. Launched by the nonprofit Coral Reef Alliance, with lead and senior authors at the University of Washington, the study is one of the first to demonstrate that management that takes evolution and adaptation into account can help rescue coral reefs from the effects of climate change.

Jacqueline Padilla-Gamiño, an assistant professor in the UW School of Aquatic and Fishery Sciences, spent up to eight hours at a time in the cramped quarters of a submersible watercraft, studying the largest known coral reef in the mesophotic zone, located in the Hawaiian Archipelago.

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…

The first book documenting all of the known species of fishes that live in the Salish Sea is now available.

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.

In a paper published May 23 in Science, a team of international researchers from Simon Fraser University, University of Washington and other institutions reveals that the iconic abundance of fishes on reefs is fueled by an unlikely source: tiny, bottom-dwelling reef fishes.

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.

Families, students and children are invited to get their hands wet on Saturday with “Our Watery World,” the University of Washington’s second annual aquatic science open house.

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.
