Description: The upper Gila River in New Mexico is one of the few unobstructed rivers in the Colorado River Basin with largely intact native fish populations, including four federally listed and one state listed species.Freshwater systems throughout the West continue to be threatened by human encroachment and water development. Methodologies or decision support tools to evaluate resource management practices that foster an understanding of how fish species adapt to the effects of climate change are critical to future resource management planning.

Sky Island Alliance (SIA) is a non-governmental organizational that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land-owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity. Because of our long-standing collaborative relationships with land managers and our large corps of skilled volunteers, we were in a unique position to spearhead this project.SIA initiated this springs inventory, assessment and management planning project to develop baseline information on springs in the Sky Island...

Throughout the Arctic most pregnant polar bears (Ursus maritimus) construct maternity dens in seasonal snowdrifts that form in wind-shadowed areas. We developed and verified a spatial snowdrift polar bearden habitat model (SnowDens-3D) that predicts snowdrift locations and depths along Alaska’s Beaufort Sea coast. SnowDens-3D integrated snow physics, weather data, and a high-resolution digital elevation model (DEM) to produce predictions of the timing, distribution, and growth of snowdrifts suitable for polar bear dens. SnowDens-3D assimilated 18 winters (1995 through 2012) of observed daily meteorological data and a 2.5 m grid-increment DEM covering 337.5 km2 of the Beaufort Sea coast, and described the snowdrift...
The northern bobwhite Colinus virginianus has experienced range-wide declines over the past several decades, primarily due to habitat loss and habitat fragmentation. As northern bobwhite populations continue to decline, there is a need for studies that address the impact of habitat changes on population persistence at multiple spatial scales. Our goal was to assess changes in habitat and land use related to northern bobwhite declines across multiple spatial scales in Texas, Oklahoma, and Louisiana. We determined northern bobwhite trends for 1972–2012 using Breeding Bird Survey data. At the regional scale, we compared northern bobwhite population trends with road density (2000, 2012), human population (1970–2010),...
Yukon River Chinook salmon Oncorhynchus tshawytscha are described as having "stream-type" life histories. After emergence from river gravel, juvenile Chinook salmon feed and grow in tributary streams of the Yukon River throughout their first summer, overwinter in freshwater, and usually leave rearing areas for marine waters during the second spring/summer. Previous life history and distribution studies have shown that some age-0 Chinook salmon leave their natal streams and colonize downriver, nonnatal habitats for rearing and overwintering. A pilot study in 2006–2007 documented rearing of Canadian-origin Chinook salmon in downstream U.S. waters. A comprehensive three-year distribution study was funded by the Alaska...

PURPOSE: The exchange of lands between the U.S. Fish and Wildlife Service (FWS) and Doyon, Limited is proposed to enhance the Yukon Flats National Wildlife Refuge of Alaska. Doyon is the largest private landowner in the refuge and an Alaska Native regional corporation that has been interested in acquiring federal oil and gas interests since the refuge was established in 1980. Under the terms of an agreement in principle between the FWS and Doyon, the U.S. government would receive fee title to lease 150,000 acres of Doyon lands, including both surface and subsurface rights, with priority fish and wildlife habitats that can be incorporated into the refuge. Doyon would receive fee title to 110,000 acres of refuge lands,...
