Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America

This data set contains allele sizes for 8 previously published and 16 novel microsatellite loci, and one microsatellite redesigned for amplification in Merlins (Falco columarius) associated with circadian clock control and polymorphism that has been associated with juvenile dispersal and migratory behavior in some avian species for Merlin (Falco columbarius) from North America (n=21). Allele sizes

Streamgage Attributes, Basin Characteristics, and Seasonal Flow Regimes, Selected Streamgages in Alaska, 1914-2017

This data set contains selected information about U.S. Geological Survey (USGS) streamgages in Alaska that had at least 5 years of daily streamflow record through September 30, 2017. The goals for developing this dataset were to identify USGS streamgages that had at least 5 years of daily streamflow that responded mostly to seasonal meteorological inputs, that had a definable drainage basin above

Stable Isotope Data from Tundra Swan (Cygnus columbianus) Feathers, Alaska, 2008 and 2010

These data are in a single table that provides date and location information of Tundra Swans (Cygnus columbianus) that were sampled in Alaska for feathers that were subsequently used in a stable isotope analysis. Results of deuterium, nitrogen, and carbon stable isotope analysis of feathers are provided.

Tracking Data for Northern Fulmars (Fulmarus glacialis)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 19 satellite transmitters attached to Northern Fulmars on their breeding range in the Bering Sea and northern Gulf of Alaska, 2001-2006. Five data files are included in the "rawData" folder of this data package. Two data files (wit

Tracking Data for Tufted Puffins (Fratercula cirrhata)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 5 satellite transmitters attached to Tufted puffins on the Barren Islands in the northern Gulf of Alaska, 1995. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) cont

Continuous Records of Shallow Soil Temperature and Moisture in the Noatak River Basin, Alaska

Soil moisture and temperature were measured at four shallow depths in multiple locations within tundra and forested landscapes of the Agashashok River basin. The measurements were made continuously beginning in 2015 until the most recent download in summer, 2019 or until the sensors or loggers failed.

Meteorological Data from Two Locations in the Agashashok River Watershed, Northwestern Alaska, 2015 to 2017

Meteorological data was collected from two locations in the Agashashok River Watershed, one high in the drainage located on tundra (67.5440 N, -161.6828 E) and a second on a rocky knoll near the watershed mouth (67.2821 N, -162.5841 E). The data contain information on air temperatures, rainfall, barometric pressure, relative humidity, incoming and outgoing radiation, and wind speed and direction.

Land Cover Estimates for the Kenai Peninsula Lowlands; 1973, 2002, and 2017

These raster images represent continuous surfaces of estimated land cover types and probabilities for the western Kenai Peninsula circa 1973, circa 2002, and circa 2017.

Water Temperature and Dissolved Oxygen Measured During a Manipulative Thermal Challenge Experiment for Adult Salmonids, Yukon River, Alaska, 2018

This data set documents the temperature and dissolved oxygen of water during the implementation of a new experimental thermal challenge protocol for migrating adult Pacific salmon in remote settings. This experiment was conducted with migrating adult Chinook salmon near Pilot Station, Alaska, along the Yukon River in a location without access to utilities. The analysis of this data was published i

Gene Transcription and Heat Shock Protein 70 Abundance Results from Migrating Adult Chinook Salmon, Yukon Watershed, 2016-2017

This data set documents the gene transcription levels for a panel of 12 selected genes and the heat shock protein 70 (HSP70) protein abundance measured in the muscle tissue of individual wild Chinook salmon captured from locations within the U.S. portion of the Yukon River watershed. Chinook salmon were primarily captured in 2016 and 2017 from existing field efforts (n = 477). A small number of ad

Airborne Lidar-based Digital Elevation Models of Coastal Montague Island (Alaska) Acquired September 2018

This dataset provides a digital elevation model mosaic derived from airborne lidar data acquired in 2018 from September 2-3 over eight separate areas along Alaska's Montague Island coast, between Prince William Sound and the Gulf of Alaska.

Genetic Data from Three Accipiter Species, North America, 1996-2014

This data set provides sample collection information and genetic data used to identify relationships between groups of North American accipiters, including one hybrid. Genetic data includes gender identification, nuclear and mtDNA sequence markers, and microsatellite genotypes derived from 20 autosomal loci (Age1302, Age1303, Age1304, Age1305, Age1306, Age1307, Age1308, Age1309, Age1310, Age1311,
