Quarantine and social distancing are teaching us creative ways to interact with each other and the world at large. One way to stay connected with the natural world (and take a much needed break from screens) is to head to your window to watch the goings on of your neighborhood and visiting birds. There are a surprisingly large number of bird species that can be observed right from your living room, depending on the vegetation in your backyard, alley or street.

The next time you eat sashimi, nigiri or other forms of raw fish, consider doing a quick check for worms. 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.

In many parts of the world, there is an imbalance in the food chain. Without top predators such as wolves and grizzly bears, smaller meat-eating animals like coyotes and foxes or grazers such as deer and elk can balloon in population, unchecked. This can initiate more deer-vehicle collisions, scavenging by urban coyotes and other unnatural human-animal interactions. University of Washington researchers have discovered that large predators play a key yet unexpected role in keeping smaller predators and deer in check.

As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life. How species will cope with ocean acidification and the other consequences of global climate change is still very much unknown and could have sweeping consequences. 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.

The 2014 Carlton Complex wildfire in north central Washington was the largest contiguous fire in state history. In just a single day, flames spread over 160,000 acres of forest and rangeland and ultimately burned more than 250,000 acres in the midst of a particularly hot, dry summer. The wildfire, driven by strong winds and explosive growth, was unprecedented in how it burned the landscape, destroying more than 300 homes in Washington’s Methow Valley.
