The Wildlife Conservation Society will assess the climate change vulnerability of bird species that regularly breed in substantial populations in Alaska using the NatureServe Climate Change Vulnerability Index (CCVI) tool. Initial work will focus on breeding birds in Arctic Alaska including shorebirds, waterfowl and waterbird species (loons, gulls, terns, jaegers), and land bird species (passerines, raptors, ptarmigan).

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.

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 LCC created the Threatened Eider Geodatabase to serve as a repository for threatened eider distribution information. This database is intended to be a qualitative “first look” at where these two species of eider have been recorded and where surveys have been conducted. This dataset is intended for general planning and mapping purposes, it should NOT be used for deriving density estimates. Users are reminded that these data do not represent all locations within the geographic scope of this database that may be occupied by threatened eiders..

Shorebirds are among the most abundant and visible high-latitude vertebrates. Their ecology makes them particularly sensitive to climate change in the arctic. The current distribution of shorebirds on the Arctic Coastal Plain is poorly known because accurate data exist from just a few locations. The Arctic LCC has supported development of habitat selection models that combine bird survey data with remotely-sensed habitat maps to “fill in the gaps” where observations are sparse. In future phases, the distribution maps generated from these models could be ground-truthed and improved, and subsequently used as the basis from which to forecast future shorebird distribution for projected future climate scenarios.

The Shorebird Demographic Network is an international collaboration designed to evaluate how climate mediated changes in the arctic ecosystem are affecting shorebird distribution, ecology, and demography. The main purpose of the network is to monitor demographic parameters (e.g. nest success, adult survival) of widely distributed shorebirds, so that we may develop conservation strategies that tackle the most pressing problems facing these declining species. The Arctic LCC contribution adds monitoring components that track key environmental attributes (e.g. water and prey availability) that are expected to link climate with changing shorebird populations.This project attempted to evaluate portions of two conceptual...

To better understand and predict effects of climate change on wetlands, invertebrates and shorebirds, the ‘CEWISH’ group,composed of Cryohydrology, Invertebrate, Shorebird Food Use, and Shorebird/Population Modeling teams, collected fielddata at Barrow, Alaska, between May and September 2014–2015. The Cryohydrology team measured end-of-wintersnow accumulation, snowmelt at the landscape scale, pond water levels, and pond water and sediment temperatures. TheInvertebrate team monitored emergence at historic ponds, and documented emergence rates of dominant chironomid taxaunder different experimentally controlled thermal regimes. The Shorebird Food Use team developed a DNA library ofpotential prey items using samples...
