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....

Salmon runs are an important time when salmon migrate from the ocean to freshwater, swimming upriver to reach spawning beds. These annual events provide an important food source for both predators and for local communities. However, Recent declines in salmon runs have caused hardship in subsistence fishing communities throughout Alaska, particularly in the Yukon River Basin. To adapt to a changing climate, fishing communities, natural resource managers, and scientists need to measure and understand climate impacts onto salmon runs in this region. To monitor changes in salmon populations and manage fisheries, the Alaska Department of Fish and Game (ADFG), U.S. Fish and Wildlife Service (USFWS), and Tanana Chiefs...

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...
