Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.
This thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was …

Advancing Vegetation Monitoring Strategies in Arid Ecosystems Using Unmanned Aircraft Systems
… freely accessible satellite data using Random Forest modeling. Chapter 2 investigated an alternative to traditional photogrammetric workflows by treating individual aerial images as independent sampling units. These approaches together illustrate how UAS can bridge the gap between fine-scale …

An Exploration of Histological Variation in the Human Rib: Applications for Age Estimation Methods in Applied Anthropology
… ribs. The third manuscript applies random forest modeling to histological age-at-death estimation using N=246 midthoracic human ribs incorporating nontraditional osteon morphotypes with flexible variable inclusion. Together, the three manuscripts in this dissertation contribute to a …

Ecologically-focused calibration of hydrological models for environmental flow applications
… analyses and variance explained in random forest modeling. This was especially true when two ecologically-focused criteria were combined, suggesting the importance of multiple calibration criteria. Flow metrics from the Combined Calibration provided the strongest flow-ecology models in …

Modeling the Distribution of the Northern Hardwood Forest Type in Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus) Recovery Areas of the Southern Appalachians
The northern hardwood forest type is a critical habitat component for the endangered Carolina northern flying squirrel (CNFS; Glaucomys sabrinus coloratus) for denning sites and corridor habitats between montane conifer patches where the squirrel forages. This study examined terrain data, and …

Modeling the effects of forest management on the carbon cycle in a loblolly pine (Pinus taeda) plantation
Forests have the ability to alleviate the impact of global warming through carbon sequestration. Six forest management scenarios for a 27,000 acre study area are modeled to determine the impact of forest management on carbon sequestration. Forest management determines annual harvested volume and …

Study of Pelvic Growth and Development Through Examination of Interlandmark Distances and Geometric Morphometric Analyses: Implications for Subadult Skeletal Sex and Age Estimation
… discriminant function analysis (DFA) and random forest modeling (RF). Lastly, the utility of pelvic metrics for skeletal age estimation were assessed using the Mixed Cumulative Probit (MCP). Both unilateral and bilateral measurements demonstrated sexually dimorphic growth in the dimensions …

Carbon dynamics under natural and manipulated meteorological boundary conditions in a forest and a fen ecosystem
… soil frost on soil C dynamics in a Norway spruce forest. In a minerotrophic fen located nearby, the effect of water table lowering (as a result of summer drought) on ecosystem C dynamics was quantified. Additionally, soil C dynamics at both sites were modeled under current meteorological …

Effects of forest harvesting best management practices on surface water quality in the Virginia coastal plain
… were monitored to evaluate effectiveness of forestry best management practices (BMPs) for minimizing hydrologic and water quality impacts associated with timber harvesting. One watershed was clear-cut without implementation of BMPs, one watershed was clear-cut with the implementation of BMPs …
