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....

Climate models project the rapid warming of boreal and arctic regions of NorthAmerica. This has led to predictions that boreal forest vegetation and fauna will track these changes andshift northward into the arctic over the next century. We used a comprehensive dataset of avian pointcountsurveys from across boreal Canada and Alaska, combined with the best-available interpolatedclimate data, to develop bioclimatic niche models of current avian distribution and density for 102 nativespecies of forest songbirds. We then used a downscaling of projected climates in future periods (2011–2040, 2041–2070, 2071–2100) to assess the potential for these species to shift their ranges and increasetheir abundance across North...

This file contains information on avian nests found during this study including species, date and time found, location, status, estimated incubation dates, tiny tag and camera monitoring and retrieval information, and nest fate. Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and times were not set correctly prior to deployment. See fields...

We have gathered information on all known recaptures and resightings of marked Dunlin throughout the East-Asian Australasian flyway, as well as opportunistically at other locations. The objectives of this study were to (1) identify regional connectivity patterns within and among subspecies of Dunlin migrating and wintering along the EAAF, (2) examine the regional connectivity patterns of Dunlin of unknown subspecies captured and marked at sites on the nonbreeding grounds, (3) examine recovery patterns of arcticola Dunlin initially captured on the NW and NE portions of their Alaska breeding range, (4) examine recovery patterns of arcticola males and females, (5) examine recovery patterns of arcticola Dunlin of different...

This file includes R code to select annual sampling units for nest survival analysis on the Arctic National Wildlife Refuge using a stratified random sampling approach. We used the Generalized Random Tessellation Stratified (GRTS) procedure (Stevens and Olsen 2004) to obtain a spatially balanced sample of 28 plots in 2019 and 48 in 2022 within two of the four strata. In 2019, plots were equally allocated between wetland and moist strata, with 14 plots allocated to each. In 2022, additional plots were allocated to the moist stratum given the proportional availability on the landscape, with the final allocation being 30 moist plots and 18 wetland plots. We also selected an additional 20 “oversample” plots in each...

Collection of video files taken of avian nests by Plotwatcher Pro–Time Lapse cameras during field work conducted on the Arctic National Wildlife Refuge. Photos are organized in folders by year. Naming convention for each photo includes nest ID and camera number. Within each NestID folder are a series of TLV files saved directly from cameras. TLV files can be saved as an AVI file to view in Windows. Note, in 2019 camera date and times were not set correctly prior to deployment. See ‘ANWR nest survival nest data’ for date and time as set on the camera at time of deployment. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that...

The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...

This collection of files contains independent assessments of both the Tiny tag and camera data, as well as temperature actograms produced by Martin Bulla in his assessment of the Tiny Tag data. Each assessment is saved as a separate file, containing the name of the reviewer in the file name. Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and...

This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include nest ID. .ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings time as when the data were collected....

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...

Reproductive success is a key demographic parameter that can have profound impacts on a species’ population trend; however, broad-scale nest survival data are unavailable for all Arctic-breeding shorebird species. Accordingly, we set out to 1) measure current nest survival rates across a large area of the Arctic National Wildlife Refuge, and 2) identify predators of nests, so as to help elucidate the potential role reproductive failure plays in current shorebird population declines. This information is also relevant for assessing the indirect effects of land management decisions such as oil and gas development on a species’ reproductive success. In 2019 and 2022, we monitored 129 shorebird nests of 9 species using...
