Invasive species: fundamental and applied science
Management of invasive alien species (IAS) is notoriously difficult, with many examples of expensive, failed attempts. While there is growing consensus that prevention is better than cure, successful prevention requires user-friendly, effective methods to quantify the ecological impacts of …

Bioeconomics Of Invasive Species: The Gypsy Moth
… studies the bioeconomics and management of an invasive species. It uses gypsy moth as an example to examine the optimal control of invasive species. This dissertation is composed of five chapters. Chapter one provides an overview of the current bioeconomic research and the main questions I want …

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 …

Prevention, Control and Eradication of Aquatic Invasive Species
Invasive alien species (IAS) negatively impact freshwater ecosystems worldwide. As suppression and eradication techniques for established invader populations are often complex, costly and resource-intensive, the prevention of further invader spread is considered a key aspect of proactive management …

Marine Invasive Species in the Galapagos Marine Reserve
… transport and tourism. Invasions occur when species get transported from one region to another and establish themselves in the new habitat. These species compete for space and resources, displacing native species and changing, populations and communities. Invasive non-native species are the …

Interactions Among Invasive Species in Lakes: a Mesocosm Experiment
Nonindigenous invasive species (NIS) have become increasingly common worldwide and are one of the leading causes of biodiversity loss in freshwater. Three widespread NIS in Wisconsin lakes are rusty crayfish (Orconectes rusticus, RC), banded mystery snails (Viviparus georgianus, BMS), and Eurasian …

Understanding Invasive Species Impacts on Reclaimed Surface-Mined Lands
… umbellata) is one of the most prevalent invasive species on reclaimed mines in Appalachia and viewed as one of the main hindrances to the successful reclamation of mined land to restore native forests. In order to better assess the impact autumn olive can have on reclamation success, we …

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 …

IMPROVING THE ASSESSMENT OF SPREAD AND IMPACTS OF FRESHWATER INVASIVE SPECIES
… global freshwater biodiversity, Freshwater Invasive Species (FIS) play a key role. FIS can impact ecosystems through multiple pathways and in some areas they represent a major portion of freshwater biodiversity, both in terms of number of species and biomass. Moreover, their introduction …

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 Human-Centered Approach to Designing an Invasive Species Eradication Program
… there is a general consensus that exotic, invasive species are a primary driver of extinctions globally. By altering ecosystem structure and function, invasive species also affect human quality of life; however, not all impacts lead to negative outcomes. Given that invasive species have …

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 …

The effects of an invasive species on the structure of native ecosystems
The Australasian barnacle species Austrominius (=Elminius) modestus has been present in Europe for over seventy years, however little is known about how A. modestus interacts with native species, or how its presence may alter ecosystem function. It has been suggested that A. modestus may be an …

Ecosystem Consequences of Post-Fire Invasive Species in the Great Basin Desert
… large expanses of native sagebrush to post-fire invasive communities. The objective of this research was to test the general hypothesis that plant cover controls ecosystem function by quantifying the effect of land cover change on carbon, water and energy resources. Net carbon exchange (NCE), …

Incorporating social science into fisheries management to address challenges from aquatic invasive species
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-15 without embargo terms

Bottom-up effects of aboveground biota, invasive species and drought on soil animal communities
… the associated role of carrion beetles), and an invasive leaf litter shredder (lawn shrimp) at varying leaf litter densities. The impact of extreme drought on nematodes and microarthropods was examined in a field experiment, pairing drought simulation with grassland association manipulation. …

A comparative study of the seed bank dynamics of two congeneric alien invasive species
… those factors contributing most to their invasive success. This information was then used to assist in developing optimal control methods. On the basis of information available prior to this study, it was predicted that both species would have large, persistent seed banks in the so.il, and …
