This dataset contains count and detection-nondetection data of Barred Owls from 106 historical breeding territories of Northern Spotted Owl territories (i.e. sites) in the Oregon Coast Ranges from 1995 to 2016. Data collected from 1995 to 2014 are partitioned into 2-week periods from 1 March - 31 August each year, totaling 12 possible sampling periods per year. Data collected from 2015 and 2016 ar

This is a comma separated values (csv) file used to conduct the logistic quantile regression analyses in R provided by Cade et al. (2017. Logistic quantile regression provides improved estimates for bounded avian counts: A case study of California spotted owl fledgling production. The Auk: Ornithological Advances. In press). The data set consists of records of California spotted owl fledgling c

Mesopelagic fishes represent an important component of the marine food web due to their global distributions, high abundances and ability to transport organic material throughout a large part of the water column. This study combined stable isotope (SIA) and gut content analyses (GCA) to characterize the trophic structure of mesopelagic fishes in the north central Gulf of Mexico. Additionally this

This U.S. Geological Survey (USGS) Data Release contains tree-core, groundwater, and soil data collected at the Vienna Wells Superfund site in Vienna, Missouri by the U.S. Geological Survey between 2011 and 2016. Concentrations of tetrachloroethylene (PCE), trichloroethylene (TCE), and 1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113) are reported for each location or sample in each medium. Tree-cor

Attenuation Factor (AF; Rao and others, 1985) and DRASTIC (Aller and others, 1987) models were developed for the Upper Floridan aquifer within the Southwest Florida Water Management District (SWFWMD) boundaries. The models were compared to assess the ability of each of these models to indicate the vulnerability of groundwater resources to contamination by Ethylene Dibromide and Bromacil pesticides

This dataset provides information on the current status and various other habitat and descriptive attributes of the native coastal vegetation for seven of the main Hawaiian Islands (i.e., does not include Niihau). This study was focused on identifying sites that still retain relatively intact and highly diverse native coastal plant communities throughout seven of the main Hawaiian Islands (Kaua

Expansion of renewable energy development is rapidly transforming the Mojave Desert landscape and has the potential to impact Golden Eagles through loss of foraging habitat and reduced prey base. Regional information on Golden Eagle food habits is limited and little is known of how dietary variability influences eagle productivity. We examined diet using motion activated trail cameras and collecti

Marine mussels are a ubiquitous and crucial component of the nearshore environment, and new genomic technologies exist to quantify molecular responses of individual mussels to stimuli, including exposure to polycyclic aromatic hydrocarbons (PAHs). We used gene-based assays of exposure and physiological function to assess lingering oil damage from the 1989 Exxon Valdez oil spill using the Pacific b

These present data on sediment carbon from soil cores taken from within submerged aquatic vegetation beds from fresh to saline coastal locations in southeast Louisiana. Water quality, site location, vegetation biomass and species composition are recorded.

These data include descriptions of all roadside segments surveyed, including GPS waypoints and verbal descriptions for each point (every half mile), survey data collected on roadside surveys in 2003-2005 in the months of July and August, along roads within the known breeding range of the Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus).

Major flood events have the potential to impact water quality. In this study, the effects of the September 2013 South Platte River flood in Colorado were assessed on the urban water cycle and basin-wide scales using time-series water sampling of three source waters (tap water, wastewater treatment facility effluent, and receiving stream) and a longitudinal sampling of the South Platte River and it

A hydrologic monitoring network was installed to investigate landslide hazards affecting the railway corridor along the eastern shore of Puget Sound between Seattle and Everett, near Mukilteo, Washington. During the summer of 2015, the U.S. Geological Survey installed instrumentation at four sites to measure rainfall and air temperature every 15 minutes. Two of the four sites are installed on cont
