The influence of recent climate change on the world’s biota has manifested broadly, resulting in latitudinal range shifts, advancing dates of arrival of migrants and onset of breeding, and altered community relationships. Climate change elevates conservation concerns worldwide because it will likely exacerbate a broad range of identified threats to animal populations. In the past few decades, grassland birds have declined faster than other North American avifauna, largely due to habitat threats such as the intensification of agriculture. We examine the effects of local climatic variations on the breeding performance of a bird endemic to the shortgrass prairie, the Lark Bunting (Calamospiza melanocorys) and discuss...

Playa wetlands on the west-central Great Plains of North America are vulnerable to sediment infilling from upland agriculture, putting at risk several important ecosystem services as well as essential habitats and food resources of diverse wetland-dependent biota. Climate predictions for this semi-arid area indicate reduced precipitation which may alter rates of erosion, runoff, and sedimentation of playas. We forecasted erosion rates, sediment depths, and resultant playa wetland depths across the west-central Great Plains and examined the relative roles of land use context and projected changes in precipitation in the sedimentation process. We estimated erosion with the Revised Universal Soil Loss Equation (RUSLE)...

The environment is rapidly changing and global warming brings impacts to all forms of life. This report is about the effects of a changing climate on the human environment and changes to communities and peoples’ lives. The best measures of change are the observations of people who live and work here, travel the trails, watch the weather, and harvest food from the land and sea. By listening, we learn the nature of the changes that are occurring, and gain insight into the causes and specific implications to people and the adaptations that are being developed and used every day. People of the Bering Strait are excellent observers of environmental change because of their local knowledge and expertise about the weather,...

Using a bioclimatic envelope approach, University of Alberta investigators project how the distribution and abundance of boreal forest birds across North America will respond to different scenarios of future climate-change. Investigation emphasis is on mapping and quantifying potential range expansions of boreal bird species into Arctic and subarctic regions across Alaska and Canada. The final products demonstrate a broad continental-scale overview of potential shifts in avian distribution.
Viable sockeye salmon populations are critical to the economy, culture, and freshwater ecosystems of Bristol Bay in Western Alaska, and it is unclear how populations might respond to warming temperatures during the critical life history stages of spawning and embryo incubation. The overarching goal of the project is to understand how temperature might influence population-specific patterns of embryo incubation, timing of hatching and fry emergence, and sockeye salmon embryo survival. By combining analyses of data from two large lake systems in the Kvichak watershed, laboratory rearing experiments to elucidate functional relationships, and simulation modeling, this project quantifies biological responses to changing...
The Red-throated Loon is the smallest of the world’s five loon species. This species typicallybreeds in low wetlands in both tundra and forested terrain (Barr et al. 2000). They nest on pondedges, sometimes along very small ponds (<1 ha), particularly in parts of their range sympatricwith Pacific Loons (Barr et al. 2000). Red-throated Loons are unique in that they regularlyforage on fish away from their nesting ponds.In Arctic Alaska this often involves flights to theArctic Ocean (Andres 1993). Like Yellow-billed Loons, the North American breedingpopulation, north of 68° latitude, appear to winter primarily in East Asia from the western KurilIslands to the Yellow Sea (J. Schmutz et al., unpublished data). In 1993,...
The Peregrine Falcon is one of the most ubiquitous bird species with a breeding distributionranging from tundra to the tropics. In Arctic Alaska this bird’s breeding stronghold is found inmajor river systems where cliff ledges abound and serve as preferred nesting sites. PeregrineFalcons prey on a wide variety of bird species ranging from small passerines to medium-sizedducks and will also take small mammals (White et al. 2002). This species travels widely andArctic-breeding Peregrine Falcons make some of the longest migrations of any bird species. TheNorth American subspecies (tundrius) winters in Central and South America (White et al. 2002).The global population is estimated at ~1.2 million individuals (BirdLife...
These data represent a potential future condition of large block grasslands if CRP lands expire and the land-use reverts back to cropland. Data layers for 2022 and 2027 were calculated by reclassing CRP lands scheduled to expire prior to these years to cropland and recalculating the large block grasslands layer as described above.

These data represent Conservation Reserve Program (CRP) lands and their scheduled expiration date. CRP lands are those with a cropping history that have been enrolled in a program to plant grass cover for wildlife, erosion, and other benefits. CRP contracts are normally 15 years in length. These data are proprietary to the Farm Service Agency and are available to PLJV through an MOU that prohibits their dissemination. Analyses derived from these data will be available to refuge staff and MOUs may be developed in the future to share the data directly.

Habitat hotspots were mapped for migratory birds ‘guilds’ across the LCD region using species presence/absence data collected from citizen-science datasets and modelled habitat conditions from the LANDFIRE program (Rollins, 2009). For presence/absence data, we used the eBird Reference Dataset (ERD, accessed October 1st, 2016; summarized in Sullivan et al., 2009) to model guild-level response to prevailing vegetation structure (e.g., percent-cover grass, tree, shrub, vegetation height), topography, and water availability for priority migratory bird species outlined in the Rio Mora NWR Land Protection Plan. We parsed eBird species “checklists” for species observed within a ~ 500 kilometer radius of the Rio Mora NWR....

The wind energy development suitability product is a per-pixel (30 square-meters) model representation of the predicted probability (0.00-1.00) that an area can support wind energy development. The result is represented as a percentage, such that any value greater-than 0.5 would be classified as suitable for wind energy development in model space. To model suitability for wind energy development, we used 9,399 observations of ‘windmills’ taken from the FAA Digital Obstruction File (http://bit.ly/dof_12549; accessed June, 2016). Because the extent of the LCD region is limited to the panhandle region of Texas, we excluded all windmill observations outside of Texas from consideration during model building. To generate...

Climate models project the rapid warming of boreal and arctic regions of NorthAmerica. This has led to predictions that boreal forest vegetation and fauna will track these changes andshift northward into the arctic over the next century. We used a comprehensive dataset of avian pointcountsurveys from across boreal Canada and Alaska, combined with the best-available interpolatedclimate data, to develop bioclimatic niche models of current avian distribution and density for 102 nativespecies of forest songbirds. We then used a downscaling of projected climates in future periods (2011–2040, 2041–2070, 2071–2100) to assess the potential for these species to shift their ranges and increasetheir abundance across North...

The King Eider, conspicuous for the male’s elegant plumage, is a common nester on the ArcticCoastal Plain of Alaska. King Eiders typically nest in wet lowland tundra with many small pondsand pools, islands, and wet marshes. Dry tundra is also used when small lakes and ponds areavailable nearby as foraging areas (Powell and Suydam 2012). Unlike other eiders, this species isnot as closely tied to coastal breeding habitats. During the breeding season, their diet is primarilyomnivorous (Powell and Suydam 2012). Alaskan breeders spend their winters in marineenvironments mostly in the Bering Sea and along the Aleutians (Powell and Suydam 2012).Eider populations have declined since the 1970s (Powell and Suydam 2012). Current...
The Common Redpoll is an abundant finch of northern regions around the world. Redpolls occurthroughout Alaska, thriving in habitats ranging from boreal to tundra across a wide elevationgradient (Knox and Lowther 2000). This species nests in trees when available. In tundra habitats,they nest in willows (primarily along riparian areas) or on the ground (Knox and Lowther 2000,J. Liebezeit, unpublished data). While primarily a seed eater, in summer this species consumesarthropods to feed young (Knox and Lowther 2000). Common Redpolls winter as far north as theBrooks Range but will wander further south in irruptive years when seed-crop production fails(Knox and Lowther 2000). While their global population numbers in...
The Snow Bunting is one of the first birds to return to their Arctic breeding grounds, with malesarriving in early April. This species occurs throughout the circumpolar arctic and, as a cavitynester,will use human-made nest sites (e.g. barrels, buildings, pipelines) as readily as naturalones (rock cavities, under boulders, cliff faces; Lyon and Montgomerie 1995). Snow Buntingsconsume a wide variety of both plant (e.g. seeds, plant buds) and animal prey (invertebrates).Their wintering range is centered in the northern continental US and southern Canada although itextends north into the low arctic in some places (Lyon and Montgomerie 1995). Current globalpopulation estimate is 40 million (Rich et al. 2004).
The Brant is a small goose well known in Alaska for the tens of thousands of individuals thatmolt in the Teshekpuk Lake area of the coastal plain during the late summer. In ArcticAlaska, this species typically nests within 8 km of the coast although in the NationalPetroleum Reserve – Alaska (NPR-A) can nest up to 30 km inland (Reed et al. 1998, D.Ward, pers. comm.). Brant often nest in colonies near the upper edge of salt marshes alongsloping seacoasts or on estuarine deltas, although in areas where salt marshes are lesscommon, they will be more dispersed, nesting near small ponds and freshwater marshes (Reedet al. 1998). Brant subsist on a vegetarian diet and during breeding primarily focus on just afew species...
