Grass Growth in Mining Wastes with Compost and Endophyte Additions Grass Growth in Mining Wastes with Compost and Endophyte Additions
Phytostabilization reduces the mobility of inorganic contaminants by establishing or enhancing plant growth. For small, remote, or abandoned mines, phytostabilization may reduce potential environmental hazards—provided plants can establish and grow. We grew a widespread perennial grass, Bouteloua curtipendula, in mining wastes with and without soil (compost, lime) and microbial...
Waterborne Self-potential Data, Surface-water Temperature and Conductivity Logging data, and Electric Resistivity Tomography Data Measured at East Fork Poplar Creek, Oak Ridge, Tennessee, January-March 2022. Waterborne Self-potential Data, Surface-water Temperature and Conductivity Logging data, and Electric Resistivity Tomography Data Measured at East Fork Poplar Creek, Oak Ridge, Tennessee, January-March 2022.
Geophysical data were collected on January 13, 2022, from a reach of East Fork Poplar Creek in Oak Ridge, Tennessee to gain a better understanding of surface water/groundwater exchanges. This data release contains the following types of data: waterborne self-potential (WaSP), and surface -water temperature and conductivity data collected by the U.S. Geological Survey (USGS) from 220...
Historical (1940–2006) and recent (2019–20) aquifer slug test datasets used to model transmissivity and hydraulic conductivity of the Mississippi River Valley alluvial aquifer from recent (2018–20) airborne electromagnetic (AEM) survey d Historical (1940–2006) and recent (2019–20) aquifer slug test datasets used to model transmissivity and hydraulic conductivity of the Mississippi River Valley alluvial aquifer from recent (2018–20) airborne electromagnetic (AEM) survey d
The Mississippi River Valley alluvial aquifer (“alluvial aquifer”) is one of the most extensively developed aquifers in the United States. The alluvial aquifer is present at the land surface in parts of southeastern Missouri, northeastern Louisiana, western Mississippi, western Tennessee and Kentucky near the Mississippi River, and throughout eastern Arkansas. Historical (1940–2006) and...
lcp_centrality: Defining least-cost paths and graph theory centrality measures lcp_centrality: Defining least-cost paths and graph theory centrality measures
We present software that creates least-cost path spanning trees, a least-cost path minimum spanning tree, and graph theory centrality measures. The software was developed to support identification of population structures--specifically, greater sage-grouse (Centrocercus urophasianus), but also support other species or graph theory applications where least-cost paths are desired. We used...
Greater sage-grouse population structure and connectivity data to inform the development of hierarchical population units (western United States) Greater sage-grouse population structure and connectivity data to inform the development of hierarchical population units (western United States)
We present five hierarchical demarcations of greater sage-grouse population structure, representing the spatial structure of populations which can exist due to differences in dispersal abilities, landscape configurations, and mating behavior. These demarcations represent Thiessen polygons of graph constructs (least-cost path [LCP] minimum spanning trees [MST; LCP-MST]) representing...
North American Bat Monitoring Program: NABat Acoustic ML, Version 1.0.1 North American Bat Monitoring Program: NABat Acoustic ML, Version 1.0.1
Bats play crucial ecological roles, and provide valuable ecosystem services, yet many populations face serious threats from various ecological disturbances. The North American Bat Monitoring Program (NABat) aims to assess status and trends of bat populations, while developing innovative and community-driven conservation solutions using its unique data and technology infrastructure. To...
