For people who make a living by harvesting natural resources, income volatility is a persistent threat. Crops could fail. Fisheries could collapse. Forests could burn. These and other factors — including changing management regulations and practices — can lower harvests and depress incomes. But the ways that these forces interact to impact income, especially at the level of the individual worker, have been difficult to track.

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.

The National Science Foundation is funding the largest marine seismic-monitoring effort yet along the Alaska Peninsula, a region with frequent and diverse earthquake and volcanic activity. Involving aircraft and ships, the new Alaska Amphibious Community Seismic Experiment will be led by Cornell University in Ithaca, New York, with partners at the University of Washington and seven other research institutions. “This effort will really change the information we have at our disposal for understanding the seismic properties of subduction zones,” said Emily Roland, a UW assistant professor of oceanography and one of nine principal investigators on the project.

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.
