Matching a snail’s pace: successful use of environmental DNA techniques to detect early stages of invasion by the destructive New Zealand mud snail

Early detection of invasive species allows for a more rapid and effective response. Restoration of the native ecosystem after an invasive population has established is expensive and difficult but more likely to succeed when invasions are detected early in the invasion process. Containment efforts to prevent the spread of known invasions also benefit from earlier knowledge of invaded sites. Environmental DNA (eDNA) techniques have emerged as a tool that can identify invasive species at a distinctly earlier time point than traditional methods of detection. Here, we focus on whether eDNA techniques can be successfully applied to detect new invasions by the destructive New Zealand Mud Snail Potamopyrgus antipodarum (NZMS). It is an opportune time to apply eDNA-based detection in P. antipodarum , which is currently expanding its invasive range across eastern North America. We collected water samples from eight sites in central Pennsylvania that prior evidence indicated were not yet invaded by the NZMS but were part of the same watershed as other previously documented invaded sites. We found evidence for NZMS invasion at five of the eight sites, with subsequent physical confirmation of mud snails at one of these sites. This study is the first example of successful application of eDNA to detect a previously unidentified invasive population of NZMS, setting the stage for further monitoring of at-risk sites to detect and control new invasions of this destructive snail. This study also shows potential opportunities for invasion monitoring offered by using low-cost efforts and methods that are adaptable for citizen science.

“…This hypothesis can be evaluated by including further unsampled potential native source populations more recently invaded regions like Japan and Chile (Collado, 2014; Collado & Fuentealba, 2020; Hamada et al., 2013) as well as comparing the phenotypic means and variances of native versus invasive clones (e.g.Keller & Taylor, 2008; Levri et al., 2017; Neiman & Krist, 2016). These studies will provide a powerful test of the role—if any—of genetic and phenotypic variation in driving initial versus‐ later invasions.…”

“…These Japanese populations seem to represent an invasion that is distinct from European and US invasions (Hamada et al., 2013). Most recently, P. antipodarum was reported in central Chile in 2014 (Collado, 2014), where it has been extending its range (Collado & Fuentealba, 2020).…”

A layover in Europe: Reconstructing the invasion route of asexual lineages of a New Zealand snail to North America

Non‐native invasive species are threatening ecosystems and biodiversity worldwide. High genetic variation is thought to be a critical factor for invasion success. Accordingly, the global invasion of a few clonal lineages of the gastropod Potamopyrgus antipodarum is thus both puzzling and has the potential to help illuminate why some invasions succeed while others fail. Here, we used SNP markers and a geographically broad sampling scheme (N = 1617) including native New Zealand populations and invasive North American and European populations to provide the first widescale population genetic assessment of the relationships between and among native and invasive P. antipodarum. We used a combination of traditional and Bayesian molecular analyses to demonstrate that New Zealand populations harbour very high diversity relative to the invasive populations and are the source of the two main European genetic lineages. One of these two European lineages was in turn the source of at least one of the two main North American genetic clusters of invasive P. antipodarum, located in Lake Ontario. The other widespread North American group had a more complex origin that included the other European lineage and two New Zealand clusters. Altogether, our analyses suggest that just a small handful of clonal lineages of P. antipodarum were responsible for invasion across continents. Our findings provide critical information for prevention of additional invasions and control of existing invasive populations and are of broader relevance towards understanding the establishment and evolution of asexual populations and the forces driving biological invasion.

“…Taken together, our new data and these earlier studies hint that relevant and heritable variation -even in the almost total absence of molecular marker-based estimates of genetic diversity -was likely present in the New Zealand and, subsequently, bridgehead European populations that seeded future invasions. This hypothesis can be evaluated by including further unsampled potential native source populations more recently invaded regions like Japan and Chile (Hamada et al, 2013;Collado, 2014;Collado & Fuentealba, 2020) as well as comparing the phenotypic means and variances of native vs. invasive clones (e.g., Keller & Taylor, 2008;Neiman & Krist, 2016;Levri et al, 2017). These studies will provide a powerful test of the role -if any -of genetic and phenotypic variation in driving initial vs. later invasions.…”
