The large, highly glacierized Copper River basin is an important water resource for the south‐central region of Alaska. Thus, information is needed on the reaction of its hydrologic timing and streamflow volumes to historical changes in climate, in order to assess the possible impact of future changes. However, the basin is remote, and therefore, it has proved difficult to collect field data in a frequent temporal and spatial manner. An extension of the distributed‐parameter, physical‐process code Precipitation Runoff Modeling System, PRMSglacier, has been specifically developed to simulate daily hydrology without requiring extensive input data. In this study, PRMSglacier was used to characterize the hydrology of...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to develop from an egg to an adult. Climate change can also indirectly affect the health of fish and wildlife as their habitats change. For example, reduced food availability could lead to overcrowding and increased disease transmission, or warmer temperatures might increase stress levels, weakening immune systems and making animals...
