Synchrotron dendrochemistry: Exploring the comparison of multi-dimensional elemental analysis methodologies on tree cores using synchrotron techniques
… (i.e., ppm and ppb) of heavy metals in tree core samples. The samples used to determine this feasibility came from the arsenic (As)-laden region of Yellowknife, NT, which has had past gold mining activity for several decades. With an area of known As contamination, it was hoped that the …

Mapping the Distribution of Barrier Island Slash Pine Woodland and Determining Growth Responses of Pinus elliottii to Hurricane Katrina (2005) on Cat Island, Mississippi
… sensed data was used in conjunction with tree core and ground data to assess these relationships. Trees were selected for sampling using a point-centered quarter distance method. At each sample site, two to four radii were extracted from each tree then the stem diameter was measured. The …

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 …

Dealing with contaminated land in the ‘New Regime’: an appraisal of the use of plants as biomonitors for metal contamination analysis and risk assessment for a former landfill site in Greenwich
… become available to the surrounding biota. Trees and plants growing in the vicinity of a contaminated site may provide such a historic record. There have been few studies on their role as biomarkers to identify metal mobility or bioavailability for continuous monitoring purposes. The aim of …

Assessing the impact of greentree reservoir water management on red oak growth and anatomy in the lower Mississippi Alluvial Valley
… To preserve migratory waterfowl habitat, greentree reservoirs (GTRs) were established, providing artificial flooding during the fall and winter. Red oak species within GTRs provide vital resources, such as mast and habitat for wildlife, and make up an important part of waterfowl conservation. …

Refining dendrochronology to evaluate the relationship between age and diameter for dominant riparian trees in the Redwood Creek watershed
… of the challenges of</p> <p>analyzing riparian tree species. Three dominant tree species</p> <p>(Alnus rubra, Umbellularia californica, Acer macrophyllum)</p> <p>in the floodplain of Redwood Creek were evaluated for the</p> <p>relationship between age and diameter at breast height (DBH)</p> …

PSEUDO DIAMETER - A NOVEL CONCEPT IN DESIGNING HIGHLY BANDWIDTH EFFICIENT MULTICAST ROUTING PROTOCOLS
… can be done in two different ways: source based tree approach and shared tree approach. This research focuses on improving bandwidth utilization of source based multicast routing protocols and also provides core selection approaches for shared tree multicasting. In this work, we have defined new …
