A new study led by the University of Washington has for the first time quantified the risk for whale-ship collisions worldwide for four geographically widespread ocean giants that are threatened by shipping: blue, fin, humpback and sperm whales. In a paper published online Nov. 21 in Science, researchers report that global shipping traffic overlaps with about 92% of these whale speciesâ ranges. Only about 7% of areas at highest risk for whale-ship collisions have any measures in place to protect whales from this threat. These measures include speed reductions, both mandatory and voluntary, for ships crossing waters that overlap with whale migration or feeding areas.

It’s not clear how the juvenile male ended up so far north, but experts suggest he was motivated by his appetite. Dee Boersma, professor of biology at the UW, is quoted.

A team led by scientists at the University of Washington and the University of Aberdeen attached tiny âbackpackâ trackers to hummingbirds in the Colombian Andes to learn more about their movements. As they report in a paper published Oct. 10 in the journal Ecology and Evolution, the tracking system will aid conservation efforts in this region by revealing the previously hidden movements of hummingbirds and other small animals.

Standing on the beach in the small town of Denmark in Western Australia on Friday afternoon was a male emperor penguin, about 2,100 miles from where one might expect to find it, in Antarctica. Dee Boersma, professor of biology at the UW, is quoted.

In the College of Arts & Sciences, we are proud to celebrate our first-generation community through a collection of stories! We honor our faculty and staff, and their many contributions to our university community and beyond.

As Earth faces unprecedented climate change, a look into the planetâs deep past may provide vital insights into what may lie ahead. But knowledge of the natural world millions of years ago is fragmented. A 15-year study of a site in Bolivia by a joint U.S.-Bolivia team has provided a comprehensive view of an ancient ecosystem when Earth was much warmer than it is today, and changed how we look at the Andes.

Across the animal kingdom, models have vastly underestimated the energy costs of reproduction. Lauren Buckley, professor of biology at the UW, is quoted.

Kelp has vanished from about 80% of the shorelines around which it once grew in Puget Sound, according to a 2023 report from Washington’s Kelp Forest Monitoring Alliance. Megan Dethier, a research professor of biology at the UW and director of the UW's Friday Harbor Laboratories, is quoted.

The $900,000 award — from a collaboration between the Kavli Foundation and the National Science Foundation — will fund work by biology’s Jeff Riffell and atmospheric and climate science’s Joel Thornton. The strengths in climate science, environmental change and neuroscience that span the College of the Environment and the College of Arts and Sciences uniquely positions the UW to bridge these fields and answer novel questions.

The College of Arts & Sciences welcomes students and their families to connect with faculty and staff, learn about a variety of topics, and explore our spaces throughout Family Weekend.

The UW-led study says the din from ships forces orcas to expend more time and energy hunting for fish. Jennifer Tennessen, senior research scientist at the UW Center for Ecosystem Sentinels, is quoted.

Volcanoes spewing carbon dioxide 250 million years ago heated the climate so much that extreme El Niño events became the norm, pushing most life on Earth past its limits. Peter Ward, professor of Earth and space sciences and of biology at the UW, is quoted.

Happening September 18–27, 2024, Dawg Daze offers more than 500 events hosted by student organizations and UW departments. Kick off the fall quarter and celebrate a return to campus with these can’t-miss recommendations from the College of Arts & Sciences!

New research led by the University of Washington and the National Oceanic and Atmospheric Administration has revealed how underwater noise produced by humans may help explain why southern resident orca populations have not recovered from historic lows. In a paper published Sept. 10 in Global Change Biology, the team reports that underwater noise pollution â from both large and small vessels â forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in parts of the Salish Sea with high ship traffic.

A ‘mosquito flight simulator’ reveals a potential weakness in one species that carries malaria. Saumya Gupta, a postdoctoral researcher of biology at the UW, is quoted.
