Fish and Climate Change (FiCli) Database: Informing Climate Change Adaptation and Management Actions for Freshwater Fishes

Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fish respond to climate change in diverse and nuanced ways, which creates challenges for practitioners of fish conservation, climate change adaptation, and management. Although climate change is known to affect fish globally, a comprehensive online, public dat

Global Assessment of River Fish Production and Potential Global Change Implications

Better understanding of the overall fishery production in river systems around the world may influence general development policies and practices for aquatic systems and sustainable maintenance of an important protein source (particularly for poorer countries where fish are relatively readily available to the local human population). With this study, researchers worked to fill this knowledge gap b

Ice2O: A Continued Assessment of Icefield-to-Ocean Change in the Pacific Coastal Temperate Rainforest

The Gulf of Alaska is one of the most productive marine ecosystems on Earth, supporting salmon fisheries that alone provide large economic benefits to Southeast Alaska. The region also has a vibrant and growing tourism industry. Glaciers are central to many of the area’s natural processes and economic activities, but the rates of glacier loss in Alaska are among the highest on Earth. Glacier loss

Informing Hydrologic Planning in the Red River Valley through Improved Regional Climate Projections

Across the Southern Great Plains, increasing temperatures are expected to alter the hydrological functioning of the region by contributing to severe droughts, more intense rainfall events, and more severe flooding episodes. These changes could adversely affect human and ecological communities. The ability to better predict future changes in precipitation and the response of hydrologic systems in t

Informing the Management and Coordination of Water Resources in the Rio Grande Basin

Understanding how to manage scarce water during drought is one of the great challenges we face as a society, particularly for communities in the Rio Grande Basin. Severe drought coupled with human development have profoundly impacted the quantity and quality of water in the basin. Running through Colorado, New Mexico, Texas, and Mexico, the Rio Grande is a multi-national resource that is managed b

Integrated Scenarios Tools: Improving the Accessibility of the Integrated Scenarios Data

The Integrated Scenarios of the Future Northwest Environment project (an FY2012 NW CSC funded project), resulted in several datasets describing projected changes in climate, hydrology and vegetation for the 21st century over the Northwestern US. The raw data is available in netCDF format, which is a standard data file format for weather forecasting/climate change/GIS applications. However, the she

Possible Future Changes to Water Resources in the Salt and Verde River Basins Associated with Atmospheric River Events

The Salt and Verde river basins in northeastern Arizona are a vital source of fresh water for the greater Phoenix metropolitan area and for two Native American tribes who rely on the basins’ natural resources for their livelihoods. The region depends on winter rain and snow to replenish the river basins’ water supply. Atmospheric rivers – long, narrow channels in the atmosphere that carry water va

River’s End: Mapping Patterns of Stream Drying in the Western United States

Water in the western United States is disappearing, and several states are facing severe water shortages as drought conditions worsen. Many streams are drying up, and there is growing concern that this trend will only continue as climate change produces warmer and drier conditions. The loss of stream ecosystems has far reaching ecological, social, and economic implications. Species that depend on

The Effects of Drought on Rio Grande Cutthroat Trout: The Role of Stream Flow and Temperature

Increasing temperatures and decreasing precipitation threaten the persistence of the Rio Grande cutthroat trout, the southernmost subspecies of cutthroat trout, found only in parts of New Mexico and Colorado. This subspecies appears to be more vulnerable to drought than more northern subspecies, because it occupies small and fragmented streams which are at greater risk of drying up during drought
