Intraguild predation dataset for arthropods on tarweed plants
Data on intraguild predation of arthropods on the tarweed Hemizonia congesta. Arthropod counts (predators, herbivores, etc) and counts of entrapped arthropod corpses on focal plants in an experiment manipulating arthropod carrion amount and plant damage. Quantifications of plant damage and reproduction are presented.
Mineral content, bulk density, and beryllium-7 activity of wetland soils of the Davis Pond Freshwater Diversion Outfall Area, Louisiana, in 2015
These data provide information regarding beryllium-7 radioisotope activity, bulk density, and percent organic matter for wetland soils in the immediate outfall region of an operational Mississippi River diversion. From them, information relating to short-term mineral sediment mass accumulation rates and sediment retention rates in the receiving basin can be inferred.
Microclimate influences mangrove freeze damage: Implications for range expansion in response to changing macroclimate
In this data release, we present data from three nights of chilling temperatures in 2015 (18th/19th January 2015; 18th/19th February 2015; 5th/6th March 2015) and from three nights of freezing temperatures in 2017/2018 (6th/7th January 2017; 1nd/2nd January 2018; 16th/17th January 2018). In the paper that accompanies this release, we synthesized hypotheses regarding the effects of microclimatic va
Low-streamflow trends and basin characteristics for 2,482 U.S. Geological Survey streamgages in the conterminous U.S.
This data release contains drainage basin characteristics and low-streamflow trend results for 2,482 U.S. Geological Survey (USGS) streamgages in the conterminous U.S. Data include streamgage identification number, name, drainage area, latitude, longitude, percent developed land use, percent crop land use, dam storage, streamgage classification, record completeness status, and trend slopes and sig
Breeding bird species in peatland habitats, Seney NWR, 2007-2009
The avian community of peatland habitats were surveyed along belt transects established in multiple units of Seney National Wildlife Refuge, representing peatland habitats dominated by a range of sedge to shrub cover at varying levels. Surveys were conducted during the 3-week period of mid-May to early June and again during mid-June-early July in three years (2007-2009). Three datasets are include
The Relative Impacts of Climate and Land-use Change on Conterminous United States Bird Species from 2001 to 2075
Species distribution models often use climate data to assess contemporary and/or future ranges for animal or plant species. Land use and land cover (LULC) data are important predictor variables for determining species range, yet are rarely used when modeling future distributions. In this study, maximum entropy modeling was used to construct species distribution maps for 50 North American bird spec
33 high-resolution scenarios of land use and vegetation change in the Upper Missouri River Basin
A new version of USGS's FORE-SCE model was used to produce unprecedented landscape projections for the Upper Missouri River Basin region of the northern Great Plains. The projections are characterized by 1) high spatial resolution (30-meter cells), 2) high thematic resolution (29 land use and land cover classes), 3) broad spatial extent (covering approximately 516,000 square kilometers), 4) use o
Data Release for The dependence of hydroclimate projections in snow-dominated regions of the western U.S. on the choice of statistically downscaled climate data
Climate change information simulated by global climate models is downscaled using statistical methods to translate spatially course regional projections to finer resolutions needed by researchers and managers to assess local climate impacts. Several statistical downscaling methods have been developed over the past fifteen years, resulting in multiple datasets derived by different methods. We apply
Vegetation Community Data within a Proposed Wetland Area on the NM Boys and Girls Ranch near Bernardo, New Mexico
The U.S. Geological Survey (USGS), working in cooperation with the U.S. Fish and Wildlife Service, installed a groundwater and vegetation monitoring network in a proposed wetland area east of the Rio Grande near Bernardo, New Mexico on the NM Boys and Girls Ranch, at a site now known as the Blue Heron Wildlife Preserve (BHWP). In September of 2016, baseline vegetation data were collected across th
Dissolved organic carbon concentration and dissolved organic matter characteristics in surface water samples from the U.S. Geological Survey National Water Quality Network rivers, 2008 to 2018
The sampling of 41 hydrologically diverse rivers that are monitored through the National Water Quality Network (NWQN) by the U.S. Geological Survey (USGS) took place during the water years of 2008 through 2018. Water samples were collected and filtered in the field (unless otherwise noted) using 0.45 micrometer pre-rinsed capsule filters (Versapor membrane), silicon tubing, and a peristaltic pump.
Polychlorinated biphenyl concentrations in adult walleye from the Fox River (Wisconsin) population, 2014
Adult walleye (10 females and 10 males) were caught in Fox River (Wisconsin) during April 2014. Total length, weight, and age were determined for each of the walleye. Whole-fish homogenates were prepared during 2017. Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018. For each sample, PCB congener concentration
Velocity and Bathymetry Surveys of the Columbia River near Northport, Washington, May 2018
Boat-mounted acoustic doppler current profilers (ADCPs) were used to collect velocity data on the Columbia River in a small area near Northport, WA. Velocity surveys were collected during two surveys at high-flow, high-stage conditions in May 2018. Bathymetric data were also collected during one of the surveys using a single-beam echo-sounder. The datasets here provide 1) raw ADCP and single-beam
