Rockin’ in the eDNA world: Testing and applying environmental DNA (eDNA) for applied ecology and conservation
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-08-01

Assessing variability in eDNA metabarcoding: implications for ecological interpretation in environmental monitoring
… involved and understanding of variability within eDNA use has been slower. Scottish aquaculture has adopted eDNA metabarcoding into its environmental<br/>impact monitoring, providing a real-world example of eDNA use with standardisation gaps. This thesis focused on eDNA metabarcoding, primarily of …

Barcoding and eDNA metabarcoding of a rapidly changing Neotropical freshwater fish community
… Furthermore, I evaluated the application of eDNA metabarcoding as a fish biodiversity assessment tool, along the course of the Jequitinhonha river. Results for the Doce suggested the occurrence of potentially cryptic species, species complex, or historical errors in morphological …

Environmental DNA (eDNA) Metabarcoding: Analysis of Freshwater Macroinvertebrate Community Structure and Diversity
… sampling are being explored. Environmental DNA (eDNA) metabarcoding, which can be used to identify the taxonomic composition of entire communities, has the potential to increase both survey efficiency and taxonomic resolution. In this study, I evaluated the efficacy of eDNA metabarcoding to …

DNA+eDNA: integration of traditional and emerging tools for monitoring marine ecosystems
… for conservation efforts. Environmental DNA (eDNA) has revolutionized biodiversity studies, offering high-throughput, non-invasive methods for assessing community composition and species distribution. Indeed, part of the present thesis focuses on optimizing eDNA methodologies and applying them …

16S rRNA sequence analysis of silver carp microbial community in eDNA water samples
… system taking triplicate environmental DNA (eDNA) water samples from 150 L tanks containing set numbers of invasive Silver Carp. Analysis eDNA samples typically involves only targeting the species of interest. However, eDNA detection alone cannot undeniably confirm the presence of the species …

Comparing fine-scale temporal environmental DNA (eDNA) sampling to camera trapping for detecting mammalian carnivores
… and stress to the animals. Environmental DNA (eDNA) has emerged as a cost-effective, non-invasive, and efficient biodiversity monitoring method which has been used for both aquatic and terrestrial species. Previous mammalian eDNA-based studies have effectively detected terrestrial and …

Using eDNA to construct community assemblages of amphibians at sites infected with Batrachochytrium salamandrivorans in the Netherlands.
… Bsal may cause. Utilising environmental DNA (eDNA) metabarcoding is a relatively new and effective method of monitoring biodiversity, especially elusive species. Thus the aims of this study are to 1.) validate the use of two different metabarcoding primers and single-species approaches in …

Overwintering habitat modeling and eDNA detection for the Eastern Massasauga (Sistrurus catenatus) in a southwestern mesic prairie
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Using eDNA and Habitat Suitability Modeling to Better Understand the Range and Habitat Requirements of the Eastern Black Rail
… method for Black Rail using environmental DNA (eDNA) and an ecological niche model identifying areas and characteristics of suitable habitat for this species. To detect Black Rail eDNA I developed a qPCR assay that targets a 219-bp region of the cytochrome c oxidase subunit 1 gene (COI) and uses …

Downstream Transport of Zebra Mussel (Dreissena polymorpha) Environmental DNA and its Implications for Analysis
Collection and analysis of environmental DNA (eDNA; genetic material that organisms shed into their environment such as sloughed cells and other wastes) enables detection of organisms without direct observation, promoting earlier detection and more rapid response than conventional sampling methods. …

e(lasmo)DNA : the role of environmental DNA (eDNA) analysis in marine fish biodiversity assessment, with special focus on elasmobranchs
… and application of an environmental DNA (eDNA) approach for the assessment of marine communities, and particularly of elasmobranch species. This novel eDNA approach was developed to investigate elasmobranch diversity in order to assess species richness in areas of special conservation …

Environmental influences on particle size distribution of Dreissena polymorpha environmental DNA in a Texas reservoir
Environmental DNA (eDNA) analysis provides an effective biodiversity survey method based on the analysis of genetic material shed into the environment and collected in bulk environmental samples such as water or sediment. With the expansion of eDNA applications, it is becoming increasingly …

Investigating the Utility of Environmental DNA Analysis for the Monitoring and Management of Mid-Atlantic Alosine Fishes
Environmental DNA (eDNA) tools can address gaps in fish assessment data while reducing the cost and the impact of sampling on threatened anadromous alosine fishes in Chesapeake Bay. Here, I tested the ability of high-frequency eDNA sampling of river herring to predict fish abundances from …

Examining uncertainty in environmental DNA analyses in freshwater lotic systems
The use of environmental DNA (eDNA) to quantify aquatic biodiversity is a rapidly emerging technique used for academic, government, and private purposes. The ease and relative low costs of taking environmental samples versus other methods of sampling makes eDNA methods an attractive choice, …

Development of a robust, standardised protocol for monitoring the distribution, abundance, and ecology of the Freshwater Pearl Mussel, <i>M. margaritifera</i>
… tools would be of benefit. Environmental DNA (eDNA) surveying involves sampling from the environment under the assumption that DNA from organisms of interest will be collected should they be/have been present. eDNA has been applied in the case of M. margaritifera previously, but further …

A CREDIBILITY, RELEVANCE AND LEGITIMACY FRAMEWORK ANALYSIS OF ENVIRONMENTAL DNA FROM THE POINT OF VIEW OF POTENTIAL END-USERS
… environment, also known as environmental DNA (eDNA). While there are many studies on the scientific and technical aspects of eDNA, not much attention has been paid to users’ and decision-makers’ perspectives on eDNA and their implication in aquatic environmental monitoring and assessment. …

Environmental DNA metabarcoding and citizen science as a cost-effective and rapid tool for monitoring terrestrial mammalian species
The use of environmental DNA (eDNA) has become increasingly important as a surveying technique for monitoring rare, elusive and/or invasive species. eDNA metabarcoding (which targets multiple species simultaneously) has been frequently used to monitor aquatic species but more recently, has been …
