Phytoforensics: Applications in vapor intrusion assessment
… and temporally and spatially variability. Trees are ideal candidates for environmental biomonitors because they are ubiquitous, active samplers of vapor and groundwater and because they are thought to sample over large spatial and temporal scales, effectively averaging variability. Sampling …

Monte Carlo integration in discrete undirected probabilistic models
… in and contributions to the field of Monte Carlo sampling for undirected graphical models, a class of statistical model commonly used in machine learning, computer vision, and spatial statistics; the aim is to be able to use the methodology and resultant samples to estimate integrals of functions …

Evaluating the Adaptive Genomic Landscape of Remnant and Backcross American Chestnut Populations to Inform Germplasm Conservation
The American chestnut tree (Castanea dentata) is a deciduous tree that largely exists in the eastern United States along the Appalachian Mountain range. Approximately 100 years ago, a fungal pathogen (Cryphonectria parasitica) decimated chestnut populations, resulting in the loss of billions of …

A CENTURY OF CHANGE IN FOREST STRUCTURE AND FIRE REGIME CONDITION CLASS IN A WESTERN MONTANA PONDEROSA PINE DOUGLAS-FIR FOREST
… The procedure for establishing bearing trees by the original surveyor was duplicated in the field at these corner locations in 2007, including tree data to the nearest 1 inch diameter class to produce a modern day version of the original 1902 notes. A point-to-tree sampling system was …

Relationships Between Hybrid Poplar Tree Extractives and Ground Water Contamination at a Phytoremediation Site
… with the planting of over 1000 hybrid poplar trees onsite. Creosote, a mixture of hazardous chemicals composed of 85% polycyclic aromatic hydrocarbons (PAH) had entered the site soil and ground water. After planting, a seasonal ground water testing program began that monitored the progress of …
