A new analysis by dozens of scientists – including some from UW – provides a useful update on measured and anticipated impacts of human-driven climate change on ecosystems from western forests to coastal waters. The report, “Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services,” is one of a suite of studies feeding into what will be the third National Climate Assessment, an overarching analysis of impacts on everything from transportation systems to public health. Read more about their report and findings.
French Polynesia and the Cook Islands this month created adjacent shark sanctuaries spanning 2.5 million square miles of ocean, a move that reflects a growing trend to protect sharks worldwide and more than doubles the area now off-limits to any shark fishing. Read more about what this means and why its important for ocean ecosystems.

Little is known about how much food salmon need, per river mile, to survive. And yet, chemicals, non-native (and some native) species, and habitat degradation all work to decrease the amount of food available to salmon. New research from SAFS
‘ Robert Naiman
, David Beauchamp
, and others, suggests that there are currently too many young salmon in the Columbia River Basin, and not enough food. Check out this UW News story
for more information about what this might mean for salmon restoration, or read their journal article
Recent studies have confirmed that microbes exist in the stratosphere, the atmospheric region between about 18 and 50 kilometers in altitude, a zone biologists have long thought uninhabitable. UW’s David Smith leads this search, along with researchers from ATMO and ESS. Read more about this exciting finding!
If a space alien landed on our planet, what are the odds that s/he could breathe our atmosphere? High, according to scientists. Read about why they think that; ATMO‘s David Catling is quoted.
Well, maybe they didn’t celebrate — but biologists certainly took notice! A pair of Magellanic penguins have remained faithful to each other for 16 years, according to researchers who have been monitoring the birds. Read more about this happy feat here! UW professor Dee Boersma is one of the researchers.

In their natural habitat – the forests of Indonesia – cockatoos have never been seen making or using tools. But researchers report today that Figaro, a member of a captive colony of the birds in Austria, invents and uses stick tools of his own design. Read more about this phenomenon; SEFS‘ John Marzluff is quoted.
