Factors influencing basal area growth of yellow-poplar ( Liriodendron tulipifera L.) in central West Virginia
… (Liriodendron tulipifera L.) as related to four topographic factors (aspect, slope position, steepness, and landform), two competition variables (basal area per acre and trees per acre) and four tree characteristics (age, diameter, total height, and crown diameter). These variables were plotted …

Evaluation of rainfall-induced landslide transit characterization
… varies according to geological and topographic factors in the study area. More importantly, locations with preceding landslides, regardless of occurrence time, are vulnerable to landslide reoccurrence. A systematic procedure of landslide transit characterization is developed in this …

Between Swamp and Sea: Agroforestry as Wetland Restoration in Southeast Virginia
… attention. I synthesize empirical studies on the topographic factors that determine marsh migration to derive and apply design guidelines for a loblolly pine production system. Drawing on regional geomorphology, this work proposes a phased microtopography-driven approach to enact long-term …

Characterising Sikussak and Other Forms of Ice Melange in Greenland Fjords
… a hierarchy of glacio-dynamic, environmental and topographic factors are identified. Finally, it is proposed that there exists a stabilising feedback between rapid glacier flow and sikussak formation, and that this may be threatened under future climate change.

Biophysical and Climate Analysis of the Mountain Pine Beetle (Dendroctonus ponderosae) Infestations in the Crown of the Continent, 1962 to 2014
… of beetle damage with respect to climate and topographic factors, on a regional scale, 2) there appears to be a link between local biophysical factors and winter precipitation and TPA within the CCE, and 3) a combination of a negative-phase PDO and La Niña is important in forecasting a decline …

Modeling Areal Measures of Campsite Impacts on the Appalachian National Scenic Trail, USA Using Airborne LiDAR and Field Collected Data
… the relative influence of environmental and topographic factors, both collected in the field and modeled in GIS using high-resolution topography (LiDAR) data, on areal measures of campsite impact utilizing Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression for factor …

Forest and woodland regeneration dynamics and persistence in the human- modified landscape of Greater Gombe Ecosystem, Tanzania
… strategy, we need to take into account other factors likely to affect forest attributes, including, topographic factors (e.g., slope), anthropogenic factors (e.g., wildfire), and plant functional traits (e.g., dispersal mode) on the variation of forest structure in these reserves. To provide …

The potential of LIDAR as an antisubmarine warfare sensor
… the acoustic environment. Environmental and topographic factors also play a major role. Removing or significantly reducing the acoustic capability, one forces the ASW forces to look to other technologies and sensors to compliment or replace the acoustic ones. This is where the interest of …

Multifunctional woody polycultures and their influence on soil organic carbon
… N [PMN]), inherent soil and landscape factors were quantified on samples collected using plot- and grid-based approaches to understand their influence on soil organic carbon (SOC) change. Baseline soil samples were collected in the spring of 2015 from land that was managed for decades …
