A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Big Southern Butte is one of two domes rising from a sea of basalt near the center of the eastern Snake River Plain in Idaho. The butte is one of the largest volcanic domes in the world, but at 300,000 years old it is also one of the youngest. Hikers who trek to the 7,550-foot high summit are rewarded with spectacular panoramic views. Photo by Devin Englestead, BLM Upper Snake Wildlife Biologist.
First light at Bosque del Apache National Wildlife Refuge in New Mexico. Established in November 22, 1939, the refuge has provided a critical stopover and wintering spot for thousands of sandhill cranes, geese and other waterfowl for 75 years. Bosque del Apache's sandhill crane population has multiplied from 18 birds in the 1840s to more than 20,000 birds today. Photo by Kim Hang Dessoliers (www.sharetheexperience.org).
DOINews: New Publication on Karst Ecosystems and Climate Change
In the Karst Ecosystems and Climate Change project, which was partly funded by the South Central Climate Science Center, researchers are assessing the links between climate, groundwater storage, spring flow, and ecosystem response in two contrasting major U.S. karst systems: the Edwards and Madison aquifers. Three models have been customized or developed--a high-resolution climate model, a rainfall-response model, and a species sensitivity model--that are then linked to investigate how forecasted climate scenarios might affect species supported in these two karst areas. The first publication of this study (Long and Mahler, 2013) describes the development and application of a rainfall-response model that will be used to forecast future responses to climate change in these two aquifers. Model results also were used to classify aquifer-response characteristics related to climatic cycles.
