UA Part of 'A-Team' to Reduce Climate Change Extinctions

Thursday, July 14, 2016

An international team of researchers is enlisting supercomputing to help better predict where plants and animals might end up under the effects of climate change. The project will model climate change-related shifts of species and ecosystems to suggest placement of protected areas for the future.

When Community Calls

Tuesday, June 28, 2016

When questions began pouring in after the Gold King Mine spill in Colorado in November 2015, Karletta Chief was there to find answers. A member of the Navajo Nation and UA an extension specialist, Chief was awarded more than $1 million to collect samples from the Animas River, which was flooded with more than three million gallons of toxic waste. Chief and her team will monitor the long-term effects on the Navajo farming families that depend on the river for irrigation.

UA Student Named a National Geographic Emerging Explorer

Tuesday, June 28, 2016

Half a world away, in her native Zambia, UA graduate student and lion biologist Thandiwe Mweetwa is helping preserve the country’s population of big cats. In a nod to her work, the National Geographic Society selected her to be part of its 2016 class of Emerging Explorers, a program that recognizes gifted and inspiring scientists, conservationists, and innovators who are at the forefront of discovery  and global problem solving.

Shoring Up Seal Beach

Tuesday, June 28, 2016

A giant hose took sediment from the bottom of Anaheim Bay in California and shot it over Seal Beach National Wildlife Refuge in a wide arc. The new sediment, added in layers, raised the entire elevation of the shore in an innovative project to restore lush wetland plants, habitat for endangered wildlife, and foraging sites for birds that otherwise would be lost to climate change and sea-level rise. 

Jacob Aragon, a senior in biology, estimates the age of a tree using a core from the collection.

Using the Past to Predict the Future

Tuesday, June 28, 2016

Thousands of tree cores, little rods of wood containing year-by-year information about a tree’s growth, lay forgotten in a federal storage room, gathering dust, until the collection—a research treasure trove—found its way to UA dendrochronologist Margaret Evans. To Evans, the cores represented a wealth of knowledge that had yet to be tapped­—an entirely new set of data that could help predict how climate change will affect our future forests.
