The fiber-optic cables that travel underground, along the seafloor and into our homes have potential besides transmitting videos, emails and tweets. These signals can also record ground vibrations as small as a nanometer anywhere the cable touches the ground. This unintended use for fiber-optic cables was discovered decades ago and has had limited use in military and commercial applications. A University of Washington pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring.

A new University of Washington study led by Olivia Sanderfoot reports that many birds were just as likely to be found in highly developed urban areas as they were in less-developed green spaces during the peak of the COVID-19 lockdowns. The paper was published Aug. 11 in the journal Scientific Reports. “Our findings suggest that some birds may have been able to use more spaces in cities because our human footprint was a little lighter,” said Sanderfoot, who completed the study as a doctoral researcher in the UW School of Environmental and Forest Sciences and is now a postdoctoral scholar in the Department of Ecology and Evolutionary Biology at the University of California, Los Angeles.

Around 50 years ago, Pacific oysters in the Puget Sound started dying at noticeably increasing rates during the summer, causing residents and scientists to wonder why. Researchers in what is now the School of Aquatic and Fishery Sciences investigated many factors that may cause mortalities such as bacteria, reproductive stress related to spawning and changes in other environmental conditions. The evidence collected pointed towards stress on the animals when they spawn, as the Pacific oyster spends a lot of their energy on reproduction.

As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park, a stunning jewel about two hours south of Anchorage. The study, published Aug.

When we think of wildlife ecologists, we might envision researchers traipsing through meadows, fording rivers, and tracking elusive predators on daring field expeditions. While some of these images may be accurate, those who work in quantitative ecology and conservation know that some of the most groundbreaking and essential ecological research takes place behind the computer screen, using statistics, mapping, and mathematical models.
