Fish get a break

“Salmon are fascinating in that they are just constantly curious, and are always sort of probing and waiting to take advantage of a newly suitable habitat,” says Westley [some guy from the University of Alaska]. “What seems to be happening is that these Arctic rivers are just now starting to become suitable. I think about them as sort of being ‘hopeful’ colonists in past years, that maybe now either are successful—or are on the cusp of being successful—in terms of reproducing and establishing populations.”
