Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities. That’s the main finding of a review paper published Aug. 13 in Science led by the University of Washington, with co-authors at the University of California, Berkeley, and University of Michigan.

An international group of scientists has laid out an ambitious global conservation plan for parasites. A related paper led by the University of Washington found that responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

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.

‘Fatal attraction’: Small carnivores drawn to kill sites, then ambushed by larger kin

cougar on wildlife camera

University of Washington researchers have discovered that large predators play a key yet unexpected role in keeping smaller predators and deer in check. Their “fatal attraction” theory finds that smaller predators are drawn to the kill sites of large predators by the promise of leftover scraps, but the scavengers may be killed themselves if their larger kin return for seconds.

‘The blob,’ food supply squeeze to blame for largest seabird die-off

dead common murre

When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”

Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding, according to a new study led by the University of Washington.

Piranha fish swap old teeth for new simultaneously

ct scan of a piranha fish

With the help of new technologies, a team led by the University of Washington has confirmed that piranhas — and their plant-eating cousins, pacus — lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.

Deep submersible dives shed light on rarely explored coral reefs

corals in the mesophotic zone

  Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep — about 100 to at least 500 feet below the surface — little to no light breaks through. Researchers must rely on submersible watercraft or sophisticated diving equipment to be able…

seal in lake

Lifelong chemical records stored in the canine teeth of an elusive group of harbor seals show that the seals remain in freshwater their entire lives and are likely a distinct population from their relatives in the ocean. Their home territory, Iliamna Lake, is in the heart of the proposed Pebble Mine project.

High-res data offer most detailed look yet at trawl fishing footprint around the world

trawling boat

A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. The paper shows that the footprint of bottom-trawl fishing on continental shelves and slopes across the world’s oceans often has been substantially overestimated.
