The stomach and intestines of certain Dolly Varden trout double to quadruple in size during month-long, salmon-egg-eating binges in Alaska each August. It’s the first time researchers have documented such fish gut flexibility in the wild.
The cold weather this week is delaying the blooming of cherry trees in the UW Quad.
University of Washington students have been testing low-cost materials capable of harvesting water from fog.
New work in Argentina where scientists had previously thought Earth’s first grasslands emerged 38 million years ago, shows the area at the time covered with tropical forests rich with palms, bamboos and gingers. Grit and volcanic ash in those forests could have caused the evolution of teeth in horse-like animals that scientists mistakenly thought were adaptations in response to emerging grasslands.
Do changes in the amount of fish caught necessarily reflect the number of fish in the sea? “No,” say UW researchers in a “Counterpoint” commentary in Nature.
Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. UW scientists consider the genetic underpinnings of such evolutionary rescue.
The fibrous threads helping mussels stay anchored are more prone to snap when ocean temperatures climb higher than normal.
A number of events and volunteer opportunities for UW faculty, staff and students are planned in conjunction with Martin Luther King Jr. Day.
Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
Fisheries managers should sharpen their ability to spot environmental conditions that hamper or help fish stocks, and not assume that abundance translates to sustainable harvest.
