Laboratory measurements and modeling N mineralization potential in Virginia Coastal Plain agricultural, fallow, and forest soils
(American Society of Agricultural and Biological Engineers, 2000)A long-term aerobic incubation and leaching technique was used to measure N mineralization of surface and subsurface soils (sandy loam) from agricultural,forest, and fallow sites in a Virginia Coastal Plain watershed. N ... -
Lamb performance in hardwood silvopastures, II: animal behavior in summer
(Oxford University Press, 2019-11-25)Integrating trees into pastures, a practice known as silvopasture, may benefit livestock in the summertime through the provision of shade. The purpose of this project was to compare the behavioral patterns of sheep grazing ... -
Land Cover Change in Northern Botswana: The Influence of Climate, Fire, and Elephants on Semi-Arid Savanna Woodlands
(MDPI, 2017-10-25)Complex couplings and feedback among climate, fire, and herbivory drive short- and long-term patterns of land cover change (LCC) in savanna ecosystems. However, understanding of spatial and temporal LCC patterns in these ... -

Landsat 8 Based Leaf Area Index Estimation in Loblolly Pine Plantations
(MDPI, 2019-03-02)Leaf area index (LAI) is an important biophysical parameter used to monitor, model, and manage loblolly pine plantations across the southeastern United States. Landsat provides forest scientists and managers the ability ... -
Landscape Dynamics on the Island of La Gonave, Haiti, 1990-2010
(MDPI, 2013-09-16)The island of La Gonave lies northwest of Port-au-Prince and is representative of the subsistence Haitian lifestyle. Little is known about the land cover changes and conversion rates on La Gonave. Using Landsat images from ... -
Landscape Tree Inventory and Management Plan for the United Company Corporate Campus, Bristol, Virginia
(Virginia Tech, 2010-04-27)The United Company’s corporate headquarters resides on 65 acres in a residential area just east of downtown Bristol, Virginia. The main office complex on the south side of campus is accented by a mixed landscape of trees, ... -
Lateral water flux in the unsaturated zone: A mechanism for the formation of spatial soil heterogeneity in a headwater catchment
(2017-09-30)Measurements of soil water potential and water table fluctuations suggest that morphologically distinct soils in a headwater catchment at the Hubbard Brook Experimental Forest in New Hampshire formed as a result of variations ... -

Leopard Panthera pardus fusca Density in the Seasonally Dry, Subtropical Forest in the Bhabhar of Terai Arc, Nepal
(Hindawi, 2014-07-16)We estimated leopard (Panthera pardus fusca) abundance and density in the Bhabhar physiographic region in Parsa Wildlife Reserve, Nepal. The camera trap grid, covering sampling area of 289 km2 with 88 locations, accumulated ... -
Lesser Prairie-Chicken Avoidance of Trees in a Grassland Landscape
(2017-01)Grasslands are among the most imperiled ecosystems in North America. Reasons that grasslands are threatened include conversion to row-crop agriculture, fragmentation, and changes in fire regimes. The reduction of fire ... -
Lesser prairie-chicken space use in relation to anthropogenic structures
(2019-01)The Southern Great Plains has been altered by conversion of native grassland to row-crop agriculture, which is considered the primary cause of declining lesser prairie-chicken (Tympanuchus pallidicinctus) populations. ... -
Lessons from Florida’s Experience Developing Numeric Nutrient Standards for Flowing Waters
(Virginia Water Resources Research Center, 2014-09)The December 2012 report entitled Technical and Policy Considerations and Options in Assessing Nutrient Stresses on Freshwater Streams in Virginia argued that the proposed screening process by the Academic Advisory Committee ... -
Let's Agree to Disagree: Comparing Auto-Acoustic Identification Programs for Northeastern Bats
(2019-12)With the declines in abundance and changing distribution of white-nose syndrome-affected bat species, increased reliance on acoustic monitoring is now the new "normal." As such, the ability to accurately identify individual ... -
Lidar-based estimates of aboveground biomass in the continental US and Mexico using ground, airborne, and satellite observations
(2017-01)Existing national forest inventory plots, an airborne lidar scanning (ALS) system, and a space profiling lidar system (ICESat-GLAS) are used to generate circa 2005 estimates of total aboveground dry biomass (AGB) in forest ... -
A life course approach to understanding social drivers of rangeland conversion
(Ecology and Society, 2017-01)Grassland to woodland conversion, also known as woody plant encroachment (WPE), is a global-scale phenomena caused in large part by changes in social processes that affect rural land use patterns. Woody plant encroachment ... -
Lignocellulose@ Activated Clay Nanocomposite with Hierarchical Nanostructure Enhancing the Removal of Aqueous Zn(II)
(MDPI, 2019-10-18)A lignocellulose@ activated clay (Ln@AC) nanocomposite with a hierarchical nanostructure was successfully synthesized by the chemical intercalation reaction and applied in the removal of Zn(II) from an aqueous solution. ...
