Climate change challenges the survival of fish across the world

Climate change will force many amphibians, mammals and birds to move to cooler areas outside their normal ranges, provided they can find space and a clear trajectory among our urban developments and growing cities.  But what chance do fish have to survive as climate change warms up waters around the world? University of Washington researchers are tackling this question in the first analysis of how vulnerable the world’s freshwater and marine fishes are to climate change.

Genetic sequencing tools help UW scientists distinguish coral species

James Dimond snorkeling to collect coral in Belize. He collected 27 coral samples from different environments and with a range of branch thicknesses.

Corals are key to ocean health because they support the densest, most diverse ecosystems and harbor species from turtles and algae to reef fish. UW scientists from the School of Aquatic and Fishery Sciences are looking at the burgeoning field of coral genetics to better predict, and maybe even prepare for, future threats to coral. In a new study, Ph.D. student James Dimond and Professor Steven Roberts use modern DNA-sequencing tools to figure out the relatedness of three similar-looking corals.
