Can ecological models be transferred in time and space? An investigation using a range of contrasting taxa
… to this research is the use of ecological models to explain, predict and project species distributions. Transferring ecological models into novel environments, both spatially and temporally, can prove vitally important when there is insufficient response data to create a model in the target …

Use of Geospatial Methods to Characterize Dispersion of the Emerald Ash Borer in Southern Ontario, Canada
… and GLM known as the Random Generalized Linear Model (RGLM) were applied to EAB data from 2006-2012 across Ontario. Ultimately, three risk maps were created from the 2006-2012 EAB data to validate the prediction dataset from 2013. In terms of model transferability, RGLM had the best …

Plants in urban brownfields: modeling the driving factors of site conditions and of plant functional group occurrence in a dynamic environment
… plant functional groups (PFGs) and subsequent modeling, in the first part of the thesis, I identified relevant strategies for species survival. The results revealed that dispersal in space and in time as well as vegetative persistence on sites are most crucial factors for plant survival in …

Temporal transferability assessments of vehicle ownership models and trip generation models for Boston Metropolitan Area
In the last few decades, travel demand models have undergone tremendous development and, today, are routinely used to support planning and policy decisions. But uncertainty in forecasting with such models is often overlooked, and its impact on forecast accuracy is rarely evaluated. My thesis is …

Determining the Influence of Abiotic and Biotic Predictors on Ecological Niche Models
… and are typically excluded from ecological niche models (ENMs). However, the role such interactions play in shaping species distributions is increasingly recognized, sparking the development of methods for their integration into ENMs.</p> <p>Among the most common approaches are those that limit …

Multi-scale patterns of habitat use by Roanoke logperch (Percina rex) in Virginia rivers: a comparison among populations and life stages
… rivers; and 2) examine the transfer of habitat models among rivers. Habitat availability in the three rivers indicates that the Nottoway River is least impacted by human activity, while the Pigg River is most impacted. The Roanoke and Pigg rivers are found within the same region of Virginia and …

Enhancing Compound Flood Modeling through Efficient Data-Driven, Physics-based, and Transfer Learning Frameworks
… to predict using data-driven or physics-based modeling approaches. Compound flooding arises from either concurrent or successive occurrences of flood drivers and their nonlinear interactions, including tides, storm surge, waves, precipitation, and river flow. These synergistic flood drivers are …

Statistical and process-based models for understanding species distributions in changing environments
… legacy effects (statistical species distribution model, SDM); or (ii) mechanistically model the variety of processes determining species distributions (process-based model, PBM). SDMs are widely used due to their easy applicability and ability to handle varied data qualities. But they fail to …

A New Travel Demand Model for Outdoor Recreation Trips
… and travel mode choices. In travel demand modelling, discrete choice models (DCMs) have been applied to understand and predict a wide range of choices, such as how people choose among alternative destinations for jobs, homes, shopping, personal services etc. Surprisingly, DCMs have rarely …

Insects in mountainous landscapes: Implications of landscape context and climate change
… of field and laboratory methods and statistical modelling approaches. I mapped the spatial distribution of a riparian shrub, Veronica stricta (Plantaginaceae), at different spatial scales across the Tongariro National Park, central North Island New Zealand. Patch occupancy of Trioza obscura …

Transferability of regional climate models over different climatic domains
In the continuing quest to improve climate model predictions to meet the increasing demand for knowledge on the regional effects of global climate change, it is pertinent to increase our understanding of how the underlying processes of climate are represented in the models we use to make these …

Use of Advanced Techniques to Estimate Zonal Level Safety Planning Models and Examine their Temporal Transferability
… affect safety in urban planning. Safety planning models can provide a decision-support tool that facilitates the assessment of the safety implications of alternative network plans. The first objective of this research study is to develop safety planning models that are consistent with the regional …
