Applications of ecological modeling in managing Central Appalachian upland oak stands for old-growth characteristics
Old-growth forests provide important habitat for wildlife, support the maintenance of biodiversity and serve as control areas for scientific research. Expanding current old-growth stand area by utilizing neighboring younger, managed stands allows private landowners to meet management needs and …

Comparative Ecological Modeling for Long-term Solution of Excess Nitrogen Loading to Surface Waters and Related Chronic and Systemic Human-Environment Problems
… values thus promises a solution to the global ecological crisis. Realization of such a cultural paradigm shift likely requires revisions to fundamental scientific definitions, theories and understanding of life, evolution and ecology, all of which now operate with a predominantly organismal …

MODELING APPROACHES FOR CLIMATE MITIGATION IN ALPINE FORESTS.
… for decarbonization. The second integrates ecological modeling with optimization to simulate forest growth, harvested wood products, and substitution effects under different climate and management scenarios, highlighting the importance of forest carbon stocks preservation and the relevance …

Unified Mathematical Modeling, Analysis and Simulation of COVID-19 and Ecological Processes
This dissertation is concerned with the modeling, simulation, and analysis of complex population dynamics using compartmental modeling frameworks based on ordinary differential equations (ODEs). First, we propose a mechanistic model to investigate the transmission dynamics of COVID-19, particularly …

The Influence of Environmental Change on Genetic Diversity Across Spatial and Taxonomic Scales
… data, genomics, and integrative spatial ecological modeling. Additionally, I create a novel computational tool to facilitate integrative modeling of species responses to environmental change. I find that global patterns of insect assemblage-wide genetic diversity differ from patterns …

AI-Driven Suitability Modeling for Sustainable Olive Cultivation: An Environmental Assessment in a Changing Climate
… the olive tree has high economic, cultural, and ecological value; however, it is highly sensitive to climate change. Rising temperatures and declining rainfall in drier and semi-drier regions, such as the northern part of Saudi Arabia, are threatening olive cultivation. Al-Jouf is considered a …

Integrated water resources management under uncertainty: exploring interconnected technological, infrastructural and institutional solutions
… of an integrated socioeconomic, hydrologic, and ecological modeling framework to quantify the effects of water rights allocation on a representative semiarid river basin. Through this framework we analyze the tradeoffs of several water management practices, institutional settings, and regional …

Assessing the impacts of environmental stressors on watershed ecosystem services integrating hydro-ecologic models and socio-cultural perspective
… conceptualizing the social components in hydro-ecological studies and the lack of appropriate decision support tools, decision-makers have not been able to evaluate the tradeoffs among decision alternatives that comprise uncertain information and social preferences. The overall goal of this …

Macroscopic insights from mechanistic ecological network models in a data void
… at lower levels of organization. Network modeling and analysis, being a powerful tool that can capture the interconnections that embody complex behaviour, has therefore been at the forefront of complexity science. In ecology, the network paradigm is relatively young and there remain …

Population Genomics, Ecology and Conservation of <i>Asterias</i> Sea Stars in the North Atlantic
… Taylor <em>et al.</em> 2014). In tandem with ecological modeling, such as species distribution models (SDMs), we can also assess global species distributions, and how they are influenced by these environmental factors along with genomic variation (Ehrlén & Morris 2015; Mathieu-Bégné <em>et …

Traditional Marine Management Systems in Northwest California: The Archaeology and Implications of Indigenous Stewardship Practices for Modern Marine Conservation and Restoration
… represent deeply intertwined frameworks of ecological stewardship and cultural heritage rooted in Indigenous knowledge systems, socio-cultural practices, and socio-economic relationships within marine ecosystems. These systems have endured over generations through Traditional Ecological …

Larval dispersal between hydrothermal vent habitats
… is difficult to directly test these hypotheses. Ecological modeling offers an alternative to experimental approaches to hypothesis testing. By creating a realistic model simulation, insight can be gained into which factors: vent spacing and instability (geological); flow regime (physical); or …

Mathematical models and numerical methods for the movement and life cycle of invasive pests across multiple scales
… managing these invasive pests is mathematical modeling, which enables forecasting of movements and the establishment potential of invasive species in an area, and can provide warnings to practitioners. In particular, principled models coupled with well-designed numerical methods enable …

Monitoring and assessment of macroinvertebrate communities in support of river management in northern Vietnam
… into classes ranging from very good to very poor ecological conditions. The current BMWP-Viet approach can be useful at an early stage of bio-assessment application in Vietnam. However, this method should be improved by optimising the scoring system for common taxa and development of more robust …

E pluribus unum: what individual whales can tell us about enigmatic species distribution and social organization
Large whales have historically been difficult to study and many aspects of their ecology remain unknown especially at the long -term population level. The ability to identify individual whales based on natural markings provides the opportunity to track individuals over time and space; this data may …
