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....

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...
