Several fish adapt in same way to toxic water
jsteward
At least 10 different lineages of fish have adapted to live in an extreme environment using the same mechanism, according to a study led by WSU evolutionary biologists.
The fish, which were found living in streams with highly toxic levels of hydrogen sulfide in different locations in the United States, Mexico and the island of Hispaniola, all had adapted to their harsh environments by modifying an enzyme in their mitochondria, so the toxicant could not bind to it.
The study, recently published in Proceedings of the National Academy of Sciences, challenges the idea that » More …
With support from Interdisciplinary Research and Innovation Seed (IRIS) grants, CAS faculty and graduate students in diverse areas are combining forces with colleagues across the university to tackle critical questions by integrating knowledge in a wide array of fields—criminology, biology, English, medicine, archaeology, nursing, and more.
Columbia River Chinook salmon have lost as much as two-thirds of their genetic diversity, Washington State University researchers have found. 
It turns out that sex can move mountains. A Washington State University researcher has found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. His study is one of the first to quantitatively show that salmon can influence the shape of the land.
