This model was used in Camouflage mismatch in seasonal coat color due to decreased snow duration (Mills et al. 2013, PNAS). Information about this model and analysis can be found at: http://www.pnas.org/content/110/18/7360.abstract.
Abstract: Native freshwater mussels are in global decline and urgently need protection and conservation. Declines in the abundance and diversity of North American mussels have been attributed to human activities that cause pollution, waterquality degradation, and habitat destruction. Recent studies suggest that effects of climate change may also endanger native mussel assemblages, as many mussel species are living close to their upper thermal tolerances. Adult and juvenile mussels spend a large fraction of their lives burrowed into sediments of rivers and lakes. Our objective was to measure surface water and sediment temperatures at known mussel beds in the Upper Mississippi (UMR) and St. Croix (SCR) rivers to estimate...

Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. USGS scientists worked closely with state management agencies and the National Wildlife Federation to complete several objectives that provide knowledge to aid their planning and management strategies in anticipation of coming changes. First, researchers updated a regional Great Lakes climate model to predict water level changes, water temperatures, and ice cover data for the entire Great Lakes basin 50-100 years into the future. Second, researchers used satellite data to determine whether the...
Abstract (from http://hol.sagepub.com/content/early/2015/04/21/0959683615580181.abstract): Old, multi-aged populations of riparian trees provide an opportunity to improve reconstructions of streamflow. Here, ring widths of 394 plains cottonwood ( Populus deltoides, ssp. monilifera) trees in the North Unit of Theodore Roosevelt National Park, North Dakota, are used to reconstruct streamflow along the Little Missouri River (LMR), North Dakota, US. Different versions of the cottonwood chronology are developed by (1) age-curve standardization (ACS), using age-stratified samples and a single estimated curve of ring width against estimated ring age, and (2) time-curve standardization (TCS), using a subset of longer ring-width...
The Sea Surface Temperature (SST) data of the nearshore region of the North Pacific show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The data points in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This...

One goal of the National Scale Assessment included identifying regions and associated river reaches across the United States that are most vulnerable to projected climate and land use changes. As an initial attempt to characterize river system vulnerability, we followed the definition posed by Kasperson et al. (2006) that incorporates exposure of systems to stresses like climate and land use changes, sensitivity of systems to those changes, and system resilience. This project intended to provide (1) a framework of stream classification to assess vulnerability of fish habitat under future climate change, (2) a framework of stream classification to assess vulnerability of fish habitat with projected urban and agriculture...

Florida is home to 50 endangered species, 23 National Wildlife Refuges, 9 national parks, and 119 state parks. Straddling both temperate and sub-tropical zones, the state is also unique in that it is a long and narrow peninsula, surrounded on three sides by warm water, creating a dynamic environment. The impacts of climate change, such as sea-level rise and severe storms, threaten the state’s unique biodiversity—yet managers are unsure how species will respond to these changes, which makes planning for the future difficult. In order to identify the impacts of climate change on Florida’s plants and wildlife, researchers developed regional climate scenarios identifying how temperature and precipitation patterns...
