The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerousavian species including millions of migrating and nesting waterbirds. Climate change effectssuch as sea level rise and increased storm frequency and intensity have the potential to impactwaterbird populations and breeding habitat. In order to determine the potential impacts of theseclimate-mediated changes, we investigated both short-term and long-term impacts of stormsurges to geese and eider species that commonly breed on the Yukon-Kuskokwim Delta. Todetermine short-term impacts, we compared nest densities of geese and eiders in relation to themagnitude of storms that occurred in the prior fall from 2000–2013. Additionally, we modeledgeese...

This project evaluated the potential impacts of storm surges and relative sea level rise on nesting geese and eider species that commonly breed on the Yukon-Kuskokwim Delta (Y-K Delta). Habitat suitability maps for breeding waterbirds were developed to identify current waterbird breeding habitat and distributions. Short-term climate change impacts were assessed by comparing nest densities in relation to magnitude of storms that occurred in the prior fall from 2000-2013. Additionally, nest densities were modeled using random forests in relation to the time-integrated flood index (e.g., a storm specific measure accounting for both water depth and duration of flooding) for four modeled storms (2005, 2006, 2009, and...

This dataset contains rasters that represent mapped habitat suitability indices for 8 shorebird species, a raster that represents mean habitat suitability indices for all 8 species, and a raster that represents the number of species in which the habitat suitability index exceeded the selected threshold value for each pixel. The shorebird species used for this modeling effort are American Golden-Plover [AMGP], Black-bellied Plover [BBPL], Dunlin [DUNL], Long-billed Dowitcher [LBDO], Pectoral Sandpiper [PESA], Red Phalarope [REPH], Red-necked Phalarope [RNPH], and Semipalmated Sandpiper [SESA].

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...

The Yukon–Kuskokwim Delta of Alaska,USAis a globally important region for numerous avianspecies including millions of migrating and nesting waterbirds.However, data on the current spatial distributionof critical nesting areas and the importance of environmental variables in the selection of nest locations aregenerally lacking for waterbirds in this region.We modeled nest densities for 6 species of geese and eiders thatcommonly breed on the Yukon–Kuskokwim Delta, including cackling goose (Branta hutchinsii minima),emperor goose (Chen canagica), black brant (B. bernicla nigricans), greater white-fronted goose (Anser albifronsfrontalis), spectacled eider (Somateria fischeri), and common eider (S. mollissima).Thedata...

This dataset consists of a polygon vector file representing 767 plots surveyed as part of the Program for Regional and International Shorebird Monitoring (PRISM). For each plot, information pertaining to shorebird abundance, occupancy, and species richness is provided. This dataset was derived from single-visit rapid area shorebird surveys in which 1-2 surveyors recorded all suspected breeding shorebirds within the plot boundary. These data were acquired over the Arctic Coastal Plain of Alaska during nine years between 1998 and 2008 (surveys not conducted in 2003 and 2005).

The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerous avian species including millions of migrating and nesting waterbirds. Climate change effects such as sea level rise and increased storm frequency and intensity have the potential to impact waterbird populations and breeding habitat in the near future. In order to determine the potential impacts of these climate-mediated changes, it is important to monitor the current spatial distribution of important nesting areas and understand the importance of environmental variables in the selection of nest locations. To do this, we modeled nest density for 15 species or composite species of waterbirds that commonly breed on the Yukon-Kuskokwim Delta,...

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...
