Mixtures of dissolved pesticides in 100 streams in the Midwestern U.S., 2013
Dissolved pesticides were measured in weekly water samples from 100 freshwater streams across eleven states in the Midwestern U.S. during May-August, 2013. A total of 182 pesticide compounds (94 pesticides and 88 degradates) were detected, with a median of 25 compounds detected per sample and 54 detected per site. Potential aquatic toxicity was evaluated using the Pesticide Toxicity Index and by c
Reproductive strategy, spawning induction, spawning temperatures and early life history of captive sicklefin chub Macrhybopsis meeki-Data
Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Only sicklefin chub (M. meeki) spawned successfully although sturgeon chub (M. gelida) released unfertilized eggs. All temperature and hormone treatments produced M. meeki spawns, but two treatments had similar success
Cottonwood Lake Study Area - Digital Elevation Model with Topobathy
This dataset contains a bare earth DEM, with a 0.5-square-meter (m2) cell size, of the Cottonwood Lake Study Area, Stutsman County, North Dakota. The digital elevation model (DEM) was based primarily on airborne lidar data acquired by Fugro Horizons of Rapid City, South Dakota., and made into a DEM by USGS personnel using the ArcGIS extension LP360 (QCoherent Software, 2013). Additional DEM proces
Cottonwood Lake Study Area - Wetland Vegetation Zone Spatial Data
Spatial polygons of vegetation zones for wetlands within the Cottonwood Lake Study Area, Stutsman County, North Dakota. Created from a collection of digital orthorectified images from aerial photographs of the study area.
Time-Domain Electromagnetic Data Used in the Assessment of the U.S. Part of the Mesilla Basin/Conejos-Mdanos Aquifer System in Doa Ana County, New Mexico, and El Paso County, Texas
The transboundary Mesilla Basin/Conejos-Mdanos aquifer system was identified as one of the priority transboundary aquifer systems for additional study by the United States and Mexico U.S.-Mexico Transboundary Aquifer Assessment Act of 2006. One of the largest rechargeable groundwater systems by total available volume in the Rio Grande/Rio Bravo del Norte Basin region of the United States and Mexic
Lionfish (Pterois sp.) invade the upper bathyal zone in the western Atlantic
Invasive lionfish have been widely recorded throughout the western Atlantic on both shallow and mesophotic reefs, where they have been linked to declines in reef health. In this study we report the first lionfish observations from the deep sea (>200 m) in Bermuda and Roatan, Honduras, with lionfish observed to a maximum depth of 304 m off the Bermuda platform, and 250 m off West End, Roatan. Place
Data Pertaining to Mapping the Approximate Inland Extent of Saltwater at the Base of the Biscayne Aquifer in the Model Land Area of Miami-Dade County, Florida, 2016
Data pertaining to mapping the approximate inland extent of saltwater at the base of the Biscayne Aquifer in the Model Land Area of Miami-Dade County, Florida in 2016. The inland extent of saltwater at the base of the Biscayne aquifer in the Model Land area of Miami-Dade County, Florida, was last mapped in 2011. Since that time, the saltwater interface has continued to move inland. The interface i
Greater White-fronted Goose (Anser albifrons) Habitat Use Data, Teshekpuk Lake Special Area, 2012-2013
This data release contains one table of data from a two-year study of Greater White-fronted Goose (Anser albifrons frontalis) molting ecology conducted in the Teshekpuk Lake Special Area within the National Petroleum Reserve-Alaska in 2012 and 2013.
Black Brant Banding and Recovery Encounter Histories, Alaska, 1990-2016
This data set contains two tables of live-dead encounter histories of Black Brant geese banded 4 breeding locations in the Arctic of northern Alaska and western Canada and one sub-Arctic location, the Tutakoke River colony on the Yukon-Kuskokwim Delta of Alaska, from 1990 to 2016.
Four Band Multispectral High Resolution Image Mosaic of the Colorado River Corridor, Arizona - 2013
In May 2013, the Grand Canyon Monitoring and Research Center (GCMRC) of the U.S. Geological Surveys (USGS) Southwest Biological Science Center (SBSC) acquired airborne multispectral high resolution data for the Colorado River in Grand Canyon in Arizona, USA. The imagery data consist of four bands (blue, green, red and near infrared) with a ground resolution of 20 centimeters (cm). These data are a
Data for Trap Net Captured Juvenile Lost River and Shortnose Suckers from Upper Klamath Lake, Oregon
Data included in this data set are for trap net captured juvenile suckers from Upper Klamath Lake, Oregon starting in 2001. Data were collected on fishing effort, the number of suckers captured, sucker length, and sucker species. There are two levels of data. Net level data contains 14,838 records and the data file is 2,069 KB and fish level data contains 25,236 records and the data file is 1,543
Repeated drought alters resilience of seed bank regeneration in Taxodium distichum swamps of North America
Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central United States and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern United States. Along the Mississippi River Alluvial Valley and
