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.

"While voters overwhelmingly rejected I-2117 by a 62%-38% margin (that is, voted to continue cap-and-invest), they narrowly supported I-2066 by a 51% - 49% margin (that is, they opposed transitioning from gas)," write the UW's Nives Dolšak, professor of marine and environmental affairs, and Aseem Prakash, professor of political science.

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.

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.

"Hurricanes Helene and Milton remind us of electricity infrastructure’s vulnerability to extreme weather events. However, at least one Florida community, Babcock Ranch, managed to avoid electricity shutoffs from downed power lines," write the UW's Nives Dolšak, professor of marine and environmental affairs, and Aseem Prakash, professor of political science.

Thousands of satellites in low-Earth orbit are still lighting up the sky, frustrating astronomers. Meredith Rawls, a research scientist of astronomy at the UW, is quoted.

"Kamala Harris of 2024, in a sharp deviation from Kamala Harris of 2016-20, epitomizes the emerging climate pragmatism," write the UW's Nives Dolšak, professor of marine and environmental affairs, and Aseem Prakash, professor of political science.

While big-name donors and politicians gather and spend millions against the initiative to kill Washington’s fledgling carbon market, the man behind the measure is running a guerrilla campaign to sway voters to his side. Aseem Prakash, professor of political science at the UW, is quoted. James Long, professor of political science at the UW, is mentioned.

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.

When an orca hunts salmon, it clicks and buzzes. It sends a beam of sounds from its nasal passages into the murky depths in hopes that the sound waves will bounce back and reveal the location of its next nutritious meal. Those hopes are often dashed when noise from passing vessels drowns out orcas’ sonar signals. Jennifer Tennessen, senior research scientist at the UW Center for Ecosystem Sentinels, is quoted.
