Coastal rivers draining into the Gulf of Maine are home to the endangered Gulf of Maine Distinct Population Segment of Atlantic salmon. The Gulf of Maine population began to decline significantly by the late 19th century, leading to the closure of the commercial Atlantic salmon fishery in 1948. In recent years, populations have again begun to decrease again. State and federal fisheries biologists

Tens of millions of migratory birds are dependent on wetland and riparian stopovers in arid and semiarid regions of North America. Global climate change would superimpose even greater stress on these ecosystems as indicated by climate change model predictions of higher temperatures and less precipitation in the southwestern United States. In partnership with the University of Arizona, the Nebraska

Many ungulate populations in the Rocky Mountains are predicted to respond to declining snow levels and increased drought, though in ways that remain uncertain. This project investigated how climate change may affect the abundance of Rocky Mountain ungulates, their migration patterns, the degree to which they transmit diseases to livestock, and their herbivory impact on aspen. To complete this work

Understanding how climate change will influence habitat for interior species of native salmonids is critical for effective management and recovery of these species. The US Department of the Interior, the US Department of Agriculture, state fisheries managers, and non-governmental organizations are increasingly challenged in attempting the recovery and restoration of native trout and salmon through
