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...

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 year,... Categories: Data; Tags: ANIMALS/VERTEBRATES, Application, Arctic, BIOLOGICAL CLASSIFICATION, BIRDS, All tags...

To determine how to allocate the 108 plots among strata, we initially used shorebird densities and variances (averaged across species) presented in Brown et al. (2007), but adjusted these values to include additional upland and riparian plots. Final allocation included 45 wetland plots, 35 moist plots, 12 upland plots, and 16 riparian plots.

Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/).

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...
