Consideration of biotype to improve invasive species management
… As globalization continues, the movement of species increases and provides more opportunities for introduction and establishment of nonindigenous invasive species. Species distribution models (SDM) represent widely used prevention tools to assess species’ potential ranges. Model predictions …

Big data for the benefit of aquatic invasive species management
Aquatic invasive species (AIS) are an expensive problem and the best thing we can do to manage AIS is to prevent their spread. Preventing the spread of AIS requires an interjurisdictional and big data approach to find pathways, locations, and people to prioritize for early interventions. In this …

Developing a decision support tool for improved aquatic invasive species management
Aquatic invasive species (AIS) are a serious problem with adverse ecological, economic, and social impacts. These wide-ranging impacts mean similarly wide ranges of affected and interested parties (stakeholders) and of knowledge and data types being involved in AIS decisions. Decision support tools …

A Comparative Static Analysis For Invasive Species Management Under Risk Neutral Preferences
This thesis investigates the optimal ex-ante mix of self-protection and self-insurance technologies employed to reduce the risk of biological invaders in the presence of exogenous variables within the probability and damage functions. This is accomplished by using a theoretical endogenous risk …

Social Investigation of Management Approaches to Effectively Control Scotch Broom (Cytisus scoparius) Invasion in the Sooke Region of Vancouver Island, BC
Invasive plant species, particularly Scotch broom (Cytisus scoparius), pose significant threats to biodiversity and ecosystem services on Vancouver Island by obstructing native plant restoration and elevating wildfire risks. This study investigates social perspectives on management strategies for …

Seasonal correlations between Pueraria montana var. lobata and avian species diversity and relative abundance in Hamilton County, Tennessee
Invasive species exist outside of their native ranges and can cause environmental harm where they have been introduced. One such species is kudzu (Pueraria montana var. lobata), an invasive vine in the southeastern U.S. Although kudzu is one of the most common invasive species management concerns …

Assessing the Influence of Different Inland Lake Management Strategies on Human-Mediated Invasive Species Spread
Species introduced to the Great Lakes region through shipping, pet trade, and as biological control have caused significant environmental damages and increased costs to boat owners and various water-dependent industries. Once established, some of these species, such as <i>Dreissenid</i> mussels and …

Visualising continuous intra-landscape isolation for brushtail possums using least-cost modelling
… affecting processes such as the spread of invasive species. It is therefore important to be able to produce maps that visualise how isolation changes across a landscape in order to enable better invasive species risk assessments to be undertaken. Many methods exist for quantifying isolation …

Optimizing resource allocation in computational sustainability: Models, algorithms and tools
… such as choosing a subset of locations where management actions must be taken to maximize the utility of the actions. These types of resource allocation problems involve combinatorial choices and tradeoffs between multiple outcomes of interest, all in the context of complex, dynamic systems …

A multi-temporal image analysis of habitat modification in the Coastal Watershed, NH
… increasing the potential of invasion by exotic species in vulnerable landscapes. The Coastal Watershed of New Hampshire (NH) has seen a 52% growth in population over the last 30 years which has led to marked urbanization and land use change. However, little has been done to study current land …

Optimal Management Of Biological Populations
The successful management of biological populations is essential to both the world's economic and environmental wellbeing. This includes controlling invasive species and sustainably harvesting biological resources for profit. In the first chapter we consider monitoring programs for the management …

Characteristics and Perceptions of Cost-share Funding for Emerald Ash Borer Mitigation in Virginia Urban Areas
Since most invasive forest pests first establish in urban areas, detection and containment of these pests within cities is important to the health of all forests. While the emerald ash borer (EAB) (Agrilus planipennis Fairmaire) has proved difficult to contain, efforts continue to mitigate the …

Population Dynamics Modeling and Management Strategy Evaluation for an Invasive Catfish
… their range to most Bay tributaries, the species has drawn concern from many stakeholders and scientists for its effects on at-risk and economically important native and naturalized species. My study focused on understanding the dynamics of this species based on multiple long-term …

Essays on Empirical Industrial Organization and Environmental Economics
… models of demand and dynamic models of invasive species management. In the first chapter, I analyze claims of falling business travel demand in the US following the COVID-19 pandemic. I focus on the US domestic airline market in between 2019 and 2022 and construct a structural model of …

INVASION DYNAMICS OF FRESHWATER CRAYFISH IN A MAN-DOMINATED LAND: SPATIO-TEMPORAL, ECOLOGICAL AND HUMAN DIMENSIONS
… by Fea et al., Chapter 2 aimed first to update invasive crayfish distribution, compiling occurrences from scientific and grey literature. Moreover, using Maximum Entropy (MaxEnt) modelling, high-suitability areas were identified, while both linear regression and Bayesian diffusion–growth models …

Use of genetic methods for determining patterns and processes during marine biological invasions
Invasive species are widely recognised as one of the major threats to marine biodiversity worldwide. With increasingly faster and more frequent transoceanic shipping, propagule pressure in the marine environment is likely to further increase, leading to a need for effective strategies for the early …

HEALTH OUTCOMES AND OPTIMAL CHOICES IN URBAN AREAS IN RESPONSE TO ENVIRONMENTAL SHOCKS AND CHANGES IN FOREST AMENITIES
… decisions, time use habits, and environmental management. This work exploits two distinct and unrelated shocks to forests in the United States to investigate the environmental and health economic links in urban areas between people and trees, and a proposed deeply ingrained role for …

Genome-scaled molecular clock studies of invasive mosquitoes and other organisms of societal relevance
… such as Anopheles and Drosophila, as well as to invasive mosquitoes Aedes aegypti and Aedes albopictus. Many other invasive pests are emerging worldwide aided by global trade, increased connectivity among countries, lack of prevention, and flawed invasive species management. Among them, there is …
