“…The release of bait is particularly well documented in existing literature, which finds that non-native bait species are sold in bait shops and can, likely unknowingly, contribute to the diffusion of AIS (Mahon et al 2014). Furthermore, the release of unused live bait is a conventional practice of anglers (Kilian et al 2012) who perceive the disposal of unused bait back into the water body as not only the most humane method but also beneficial to the ecosystem (Litvak and Mandrak 1993;Kilian et al 2012).…”

Exploring the efficacy of an aquatic invasive species prevention campaign among water recreationists

Water recreationists regularly engage in behavior that can contribute to the spread of aquatic invasive species (AIS), which can result in costly consequences for managers. As AIS prevention is more cost-effective than response, educational campaigns are implemented as a preventative management strategy. However, little is known about the efficacy of education campaigns in promoting recreationists' knowledge, personal responsibility, and engagement in behaviors that can prevent AIS spread. This study explored the Stop Aquatic Hitchhikers! TM (SAH!) campaign by conducting survey and focus group research with water recreationists' in Illinois and Indiana. Results from the survey research indicate moderate campaign success (55 % were aware of the SAH! campaign), and that awareness is significantly related to increases in knowledge, personal responsibility, and engagement in four of the six recommended control behaviors. Additionally, findings demonstrate that boater-anglers were most aware of the campaign (69 %), most knowledgeable of AIS species, and felt the most personal responsibility for AIS control. However, focus group results demonstrate the need for campaign enhancement, including streamlining campaign messaging and increasing campaign exposure. Policy informed by our recommendations may improve the efficacy of educational campaigns to manage recreation behavior and corresponding environmental impacts among multiple water recreationist groups.

“…Similar assays have successfully identified benthic invertebrates and their resting stages within ballast tank sediments (Darling and Tepolt 2008;Harvey et al 2009;Briski et al 2011). eDNA monitoring has also been proposed to assess authenticity of imported ornamental fish and identify potential invasive contaminant species within shipments (Collins et al 2012) as well as within the trade of bait associated with recreational fishing (Mahon et al 2014).…”

The ecology of environmental DNA and implications for conservation genetics

2015

Environmental DNA (eDNA) refers to the genetic material that can be extracted from bulk environmental samples such as soil, water, and even air. The rapidly expanding study of eDNA has generated unprecedented ability to detect species and conduct genetic analyses for conservation, management, and research, particularly in scenarios where collection of whole organisms is impractical or impossible. While the number of studies demonstrating successful eDNA detection has increased rapidly in recent years, less research has explored the ''ecology'' of eDNA-myriad interactions between extraorganismal genetic material and its environment-and its influence on eDNA detection, quantification, analysis, and application to conservation and research. Here, we outline a framework for understanding the ecology of eDNA, including the origin, state, transport, and fate of extraorganismal genetic material. Using this framework, we review and synthesize the findings of eDNA studies from diverse environments, taxa, and fields of study to highlight important concepts and knowledge gaps in eDNA study and application. Additionally, we identify frontiers of conservation-focused eDNA application where we see the most potential for growth, including the use of eDNA for estimating population size, population genetic and genomic analyses via eDNA, inclusion of other indicator biomolecules such as environmental RNA or proteins, automated sample collection and analysis, and consideration of an expanded array of creative environmental samples. We discuss how a more complete understanding of the ecology of eDNA is integral to advancing these frontiers and maximizing the potential of future eDNA applications in conservation and research.

“…The emergence of techniques that are able to detect low levels of such environmental DNA (eDNA) has enormous potential to break new ground in areas such as invasive species research456, pathogen detection7, palaeoecology8, and forensics and law enforcement9. The use of eDNA to survey rare and cryptic species that are difficult to detect using traditional methods also has wide implications for biodiversity assessment and the protection of species1011.…”

Seasonal variation in environmental DNA in relation to population size and environmental factors

Analysing DNA that organisms release into the environment (environmental DNA, or eDNA) has enormous potential for assessing rare and cryptic species. At present the method is only reliably used to assess the presence-absence of species in natural environments, as seasonal influences on eDNA in relation to presence, abundance, life stages and seasonal behaviours are poorly understood. A naturally colonised, replicated pond system was used to show how seasonal changes in eDNA were influenced by abundance of adults and larvae of great crested newts (Triturus cristatus). Peaks in eDNA were observed in early June when adult breeding was coming to an end, and between mid-July and mid-August corresponding to a peak in newt larval abundance. Changes in adult body condition associated with reproduction also influenced eDNA concentrations, as did temperature (but not rainfall or UV). eDNA concentration fell rapidly as larvae metamorphosed and left the ponds. eDNA concentration may therefore reflect relative abundance in different ponds, although environmental factors can affect the concentrations observed. Nevertheless, eDNA surveys may still represent an improvement over unadjusted counts which are widely used in population assessments but have unreliable relationships with population size.
