Researcher to Discuss Climate’s Effects on Trout Thursday

July 15, 2013

The effects of warming temperatures on Yellowstone cutthroat trout is the topic of the weekly summer lecture series Thursday, July 18, at the University of Wyoming-National Park Service (UW-NPS) Research Center. The center is located at the AMK Ranch in Grand Teton National Park.

U.S. Geological Survey researcher Robert Al-Chokhachy will speak at 6:30 p.m. at the AMK Ranch, located north of Leeks Marina. A barbecue, at a cost of $5 per person, will take place at 5:30 p.m. Reservations are not required. For more information, call the UW-NPS Center at (307) 543-2463.

Warming temperatures and altered precipitation patterns are likely to have profound effects on Yellowstone cutthroat trout, Al-Chokhachy says. He will characterize historic and expected changes in stream conditions, and unravel the complexities of how climate influences Yellowstone cutthroat trout and aquatic ecosystems.

“While the effects of climate are likely to occur across the topographically diverse Greater Yellowstone, there are clear patterns for conservation strategies to facilitate persistence of Yellowstone trout under a changing climate,” he says.

The UW-NPS Research Center provides a base for university faculty members and government scientists from throughout North America to conduct research in the diverse aquatic and terrestrial environments of Grand Teton National Park and the greater Yellowstone area.
