Arctic Peregrine Falcon Abundance on Cliffs Along the Colville River, Alaska, 1981-2002 and Covariate Input Files

    This data set consists of fourteen data files. Rcode_arctic_peregrine_abundance.R contains R code that was used to analyze Arctic peregrine falcon data collected between 1981 and 2002. The code primarily uses the R package "UNMARKED" and is based on the Dail-Madsen model for estimating population abundance. To run this code in an R environment, download the file and open it in an R interpreter (such as RStudio). The remaining files are all covariate matrices that act as inputs to the R code.

    Raw Light-Level Geolocator Data from Golden-Winged Warblers Breeding at Three Sites in North America

      21 raw light-level data files (.lig) from geolocators (Biotrak, Wareham, UK; model ML6240, 2-min light-sampling regime) deployed on 20 individual Golden-winged Warblers from three breeding locations in North America. These data were collected to provide information on the migration routes and timing, and nonbreeding locations of individuals from these populations to inform conservation and management strategies. These data are being released following the publication of these findings.

      Water Resources of the United States

        Water is one of six science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources. This database contains downloadable water-related spatial data files for exploration and analysis.

        NWRC Chemical Effects Database

          The NWRC Chemical Effects Database is a searchable database that contains bioassay records and data for chemicals analyzed and evaluated for repellency, toxicity, reproductive inhibition, and immobilization. Studies were conducted from 1943 to 1987 by the U.S. Department of Agriculture's National Wildlife Research Center (NWRC), its predecessors, and by the U.S. Geological Survey's Patuxent Wildlife Research Center (PWRC) (formerly part of the U.S. Fish and Wildlife Service). The online database comprises published data only. The entire database, including unpublished data, is currently searchable by NWRC staff.

          National Wetlands Inventory

            The US FWS National Wetlands Inventory (NWI) is a publicly available resource that provides detailed information on the abundance, characteristics, and distribution of US wetlands. NWI data are used by natural resource managers, within the US FWS and throughout the Nation, to promote the understanding, conservation and restoration of wetlands.
