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...

Warming Arctic summers unlikely to increase productivity of shorebirds through renesting. Nature Scientific Reports 11:15277.Directories include: input_files, output_files, R_code, program_mark_files, and figure_files. Found in the analysis_output folder on the RDR.Information for the Dunlin brood survival project were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these files may also be contained within the Utqiagvik shorebird project archive (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project).Th...

This data release includes grids representing the depth and thickness of drinking-water withdrawal zones, polygons of hydrogeologic settings, an inventory of sources of well construction data, and summaries of data comparisons used to assess the depth of groundwater used for drinking-water supplies in the United States. Well construction data sources are documented in Table1_DataSources.xlsx. Data comparisons using the Mann-Whitney test to assess similarity between hydrogeologic settings were used to justify combining data where they were sparse (compare_neighbors_all_domestic.txt and compare_neighbors_all_public.txt). Water-supply-well depth varies geographically by water use and the type of well, which illustrates...

Beginning in 2003, we have conducted a long-term shorebird breeding ecology study at Utqiaġvik (formerly Barrow), Alaska. The objectives of this study are to (1) collect baseline data on temporal and spatial variability of shorebird diversity and abundance, (2) collect information on nest initiation and effort, replacement clutch laying, clutch and egg size, nest and chick survival, and other demographic traits of Arctic-breeding shorebirds, (3) establish a marked population of as many shorebird species as possible that will allow us to estimate adult survival, mate and site fidelity, and natal philopatry, and (4) relate weather, food availability, and predator and prey abundances to shorebird productivity and survival....

Information on abundance, distribution, chronology, and habitat associations of birds at U.S. Air Force Long Range Radar Sites (USAF LRRS) and U.S. Navy lands is either outdated or lacking. In other situations, existing information has been obtained using a variety of incompatible methods thereby complicating the ability to discern changes to bird communities or the habitats they rely upon. Up-to-date information on the use of military lands by all bird species is important for both the Department of Defense (DOD) and the U.S. Fish and Wildlife Service (USFWS). Furthermore, updating avian inventories and implementing a standardized monitoring program across military lands helps USFWS-MBM by improving avian trend...

This GeoPackage contains the analysis strata (“YKD_AnalysisStrata”) used in calculating population indices for ducks, loons, mergansers, grebes, gulls, and terns. This layer was created from the file (“YKD_DesignStrata”) when the existing rotating panel design was developed in 1999. This layer was originally created as an ArcInfo coverage, saved to a shapefile, and imported to SQLite Database format.

Results from Generalized Additive models (GAM), Random Forest models (RFM), and Cubist models (CUB) for three Dauphin Island Sealab (DIS) operated salinity sites in Mobile Bay are reported in this data release. These sites included Meaher Park (DIS:MHPA1), Middle Bay Lighthouse (DIS:MBLA1), and Dauphin Island (DIS:DPIA1). The constructed models predicted a 40-year daily salinity record from 1980 to 2021 at each site based on incomplete imputed salinity records and several explanatory variables. Explanatory variables included: daily streamflow from 8 United States Geological Survey (USGS) streamgages, daily minimum and maximum temperature, precipitation, vapor pressure, wind speed, wind direction, horizontal and...

The degradation of critical wintering and migratory stop-over sites is known to have direct consequences on the survival and reproductive condition of migratory shorebirds. However, little is known about migratory movements and connectivity of shorebird populations. By identifying migratory stop-over and wintering areas, we can begin to identify sites that should be conserved and evaluate the relative risks of development and climate change scenarios. Beginning in 2017, we initiated a project to track the migration movements of shorebird species using Argos, GPS, and Pinpoint tags. The primary objective of this study is to collect baseline information on movement patterns of shorebirds during the post-breeding period...

This data release provides water-quality trends for rivers and streams in the Delaware River Basin determined using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model and the Seasonal Kendall Trend (SKT) test. Sixteen water-quality parameters were assessed, including nutrients (ammonia, nitrate, filtered orthophosphate, total nitrogen, total phosphorus, and unfiltered orthophosphate), major ions (calcium, chloride, magnesium, potassium, sodium, and sulfate), salinity indicators (total dissolved solids and specific conductance), and sediment (total suspended solids and suspended sediment concentration). The child items include the input and output data used in the modeling and testing of water-quality...
