“…Additional detections with eDNA sampling on this landscape were consistent with eDNA transport from a nearby, hydrologically connected site with known historical species occurrence. Further, the performance of Pyrgulopsis eDNA sampling here is consistent with the literature on morphologically similar invasive hydrobiid New Zealand Mudsnails ( Potamopyrgus antipodarum ) (Goldberg et al., 2013; Ponce et al., 2021; Woodell et al., 2021). Multiple studies have found that eDNA sampling for P. antipodarum can be effective, even for low density population detection.…”

“…For example,Goldberg et al (2013), using a taxon-specific qPCR assay, were successful in detection of P. antipodarum at densities as low as one individual per 1.5 L of water.

Environmental DNA (eDNA) sampling is a powerful tool for rapidly characterizing biodiversity patterns for specious, cryptic taxa with incomplete taxonomies. One such group that are also of high conservation concern are North American freshwater gastropods. In particular, springsnails of the genus Pyrgulopsis (Family: Hydrobiidae) are prevalent throughout the western United States where >140 species have been described. Many of the described species are narrow endemics known from a single spring or locality, and it is believed that there are likely many additional species which have yet to be described. The distribution of these species across the landscape is of interest because habitat loss and degradation, climate change, groundwater mining, and pollution have resulted in springsnail imperilment rates as high as 92%. Determining distributions with conventional sampling methods is limited by the fact that these snails are often <5 mm in length with few distinguishing morphological characters, making them both difficult to detect and to identify. We developed an eDNA metabarcoding protocol that is both inexpensive and capable of rapid, accurate detection of all known Pyrgulopsis species. When compared with conventional collection techniques, our pipeline consistently resulted in detection at sites previously known to contain Pyrgulopsis springsnails and at a cost per site that is likely to be substantially less than the conventional sampling and individual barcoding that has been done historically. Additionally, because our method uses eDNA extracted from filtered water, it is non‐destructive and suitable for the detection of endangered species where “no take” restrictions may be in effect. This effort represents both a tool which is immediately applicable to taxa of high conservation concern across western North America and a case study in the broader application of eDNA sampling for landscape assessments of cryptic taxa of conservation concern.

“…These results have the potential for application to control of invasive populations of P. antipodarum, and especially populations earlier in the invasion process (e.g. Woodell et al (2021)). These outcomes also suggest value in addressing a role for density dependence in population dynamics of other invasive freshwater taxa.…”

Species invasion can negatively affect natural ecosystems by causing biodiversity loss, changing nutrient cycling processes, and altering trophic webs. Understanding how and why some species or lineages become invasive is critically important to preventing and controlling invasions. We address whether key life history traits of invasive vs. native lineages – here Potamopyrgus antipodarum - differ in response to environmental stressors that could determine the outcome of invasions. We focus here on population density, which is a fundamental characteristic of all populations and to which native lineages of P. antipodarum are very sensitive. This New Zealand freshwater snail successfully invaded Europe in the 19th century and is a more recent invader in North America. In just a few decades, invasive populations of P. antipodarum have spread across much of North America, with detrimental effects for local food webs and native species. We quantified individual growth rate and embryo number in P. antipodarum from multiple distinct native range and invasive lineages cultured from the juvenile stage across three different population density treatments. The growth of native but not invasive lineages decreased as density increased, and reproduction in invasive but not native snails was positively affected by increased density. These results are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become invasive while others do not. Our findings also align with previous studies that show that invasive lineages of P. antipodarum exhibit a relatively wide range of tolerance to environmental stressors.

“…Prevention and early detection of biological invasions leads to the most successful economic and ecological outcomes [ 14 – 16 ]. Towards this goal, the sampling of environmental DNA (eDNA) has shown promise when applied to the detection of non-native species [ 17 ]. Targeted quantitative Polymerase Chain Reaction (qPCR) methods have successfully revealed the presence of individual species of interest, including the terrestrial toad species Bufo japonicus formosus in Hokkaido, Japan and invasive crayfish in Baden-Württemberg, Germany [ 18 , 19 ].…”

Non-native species have the potential to cause ecological and economic harm to coastal and estuarine ecosystems. Understanding which habitat types are most vulnerable to biological invasions, where invasions originate, and the vectors by which they arrive can help direct limited resources to prevent or mitigate ecological and socio-economic harm. Information about the occurrence of non-native species can help guide interventions at all stages of invasion, from first introduction, to naturalization and invasion. However, monitoring at relevant scales requires considerable investment of time, resources, and taxonomic expertise. Environmental DNA (eDNA) metabarcoding methods sample coastal ecosystems at broad spatial and temporal scales to augment established monitoring methods. We use COI mtDNA eDNA sampling to survey a diverse assemblage of species across distinct habitats in the Salish Sea in Washington State, USA, and classify each as non-native, native, or indeterminate in origin. The non-native species detected include both well-documented invaders and species not previously reported within the Salish Sea. We find a non-native assemblage dominated by shellfish and algae with native ranges in the temperate western Pacific, and find more-retentive estuarine habitats to be invaded at far higher levels than better-flushed rocky shores. Furthermore, we find an increase in invasion level with higher water temperatures in spring and summer across habitat types. This analysis contributes to a growing understanding of the biotic and abiotic factors that influence invasion level, and underscores the utility of eDNA surveys to monitor biological invasions and to better understand the factors that drive these invasions.
