The Spectacled Eider is a medium-sized sea duck with males easily recognized by their striking“clown-like” head plumage. This species was listed as threatened in 1993 under the EndangeredSpecies Act as it has suffered severe population declines in western Alaska. The Arctic CoastalPlain population may also be declining. In Arctic Alaska, breeding Spectacled Eiders use riverdeltas and wet tundra habitats, including drained-lake basins, flooded wetlands, and islets withina matrix of thaw lakes for both nesting and foraging (Petersen et al. 2000). During the breedingseason, their diet consists primarily of both adult and larval aquatic insects (Petersen et al. 2000).Alaskan breeders spend their winters offshore in...
To elucidate these potential “bottom up” effects of climate changes to Arctic ungulates and evaluate the trophic mismatch hypothesis, the Arctic Landscape Conservation Cooperative (ALCC), the Bureau of Land Management (BLM), the U.S. Geological Survey (USGS), Teck, Inc., and the National Park Service provided funding in 2012-14 to incorporate the calving and summer range of the Western Arctic caribou herd (WAH) into an ongoing inter-agency research and monitoring effort to examine the influences of climate change on the nutrient dynamics of caribou forages. This work is leveraging existing projects on the North Slope of Alaska that are primarily funded through the USGS Changing Arctic Ecosystems Initiative. Field...
More information is needed about species composition, abundance, or distribution of the microfauna and meiofauna living within the interstitial spaces of the littoral zones along the Beaufort Sea coast. Shorebirds depend on meiofauna for food for pre-migratory fattening and these organisms make important contributions to bioremediation of oil spills.The information obtained from this jointly-funded research can contribute to development of mitigation measures and strategies to reduce potential impacts from post-lease exploration and development. This information need extends to the lower trophic levels forming the base of these complex food webs and the biochemistry that influences these relationships. Their contributions...

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.
Many Arctic shorebird populations are declining, and quantifying adult survival and the effects of anthropogenic factorsis a crucial step toward a better understanding of population dynamics. We used a recently developed, spatially explicitCormack–Jolly–Seber model in a Bayesian framework to obtain broad-scale estimates of true annual survival rates for 6species of shorebirds at 9 breeding sites across the North American Arctic in 2010–2014. We tested for effects ofenvironmental and ecological variables, study site, nest fate, and sex on annual survival rates of each species in thespatially explicit framework, which allowed us to distinguish between effects of variables on site fidelity versus truesurvival. Our...

Arctic wetlands, where millions of local and migratory birds nest, are composed of a mosaic of ice wedge polygons, non-patterned tundra, and large vegetated drained thaw lake basins. Regional climate projections suggest that evapotranspiration, rainfall, and snowfall will increase, making it difficult to predict how surface water distribution might change and how habitats for the invertebrate resources used by waterbirds will be impacted. This study will focus on evaluating how climate change will affect the invertebrate community, and whether the change in climate (through changes in hydrology and surface energy balance) could induce a trophic mismatch that might alter the growth and survival of shorebird young....

The Arctic Coastal Plain (ACP) of Alaska is an important region for millions of migrating and nesting shorebirds. However, this region is threatened by climate change and increased human development (e.g., oil and gas production) that have the potential to greatly impact shorebird populations and breeding habitat in the near future. Because historic data on shorebird distributions in the ACP are very coarse and incomplete, we sought to develop detailed, contemporary distribution maps so that the potential impacts of climate-mediated changes and development could be ascertained. To do this, we developed and mapped habitat suitability indices for eight species of shorebirds (Black-bellied Plover [Pluvialis squatarola],...

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...

The Adapt Alaska Collaborative grew out of a set of initiatives to promote climate resilience and adaptation in Alaska. On May 24 and 25, 2017 a group of participants (including representatives of Alaska regional, state and federal agencies and organizations) gathered at a work session to identify next steps to build on the momentum generated by these initiatives toward a more resilient Alaska. At the work session, three working groups formed around specific areas of effort, including a Planning Working Group with the task of identifying ways to streamline the many planning requirements associated with implementing climate resilience and adaptation strategies.The Adapt Alaska Planning Working Group looked at a range...

This project provides a better understanding how linkages among surface-water availability, connectivity, and temperature mediate habitat and trophic dynamics of the Fish Creek Watershed (FCW). These interrelated processes form a shifting mosaic of freshwater habitats across the landscape that can be classified, mapped, understood, and modeled in response to past and future climate and land-use change in a spatial and temporal context. Developing scenarios of freshwater habitat change in this context provides managers and scientists with a flexible template to evaluate a range of potential responses to climate and land-use change. Applying this approach in the FCW is made feasible because of the availability of...

The Integrated Ecosystem Model for Alaska project (IEM) uses down-scaled climate models as the drivers of ecosystem change to produce forecasts of future fire, vegetation, permafrost and hydrology regimes at a resolution of 1km. This effort is the first to model ecosystem change on a statewide scale, using climate change input as a major driving variable. The objectives of the IEM project are as follows; to better understand and predict effects of climate change and other stressors on landscape level physical and ecosystem processes, and to provide support for resource conservation planning.The IEM will provide resource managers with a decision support tool to visualize future landscapes in Alaska. Model outputs...
We assessed change in the seasonal timing of insect emergence from tundra ponds near Barrow, Alaska over a four-decade timespan, and explored factors that regulate this significant ecological phenomenon. The early-summer pulse of adult insects emerging from myriad tundra ponds on the Arctic Coastal Plain is an annual event historically coincident with resource demand by tundra-nesting avian consumers. Asymmetrical changes in the seasonal timing of prey availability and consumer needs may impact arctic-breeding shorebirds, eiders, and passerines. We have found evidence of change in the thermal behavior of these arctic wetlands, along with a shift in the phenology of emerging pond insects. Relative to the 1970s, tundra...

The distribution and abundance of fishes across the Alaska Arctic is not well understood. Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.
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).
