Invasive species are one of the top two threats to native biodiversity worldwide (Mack et al. 2000). A primary goal of invasion biology is to predict which introduced species become invasive, or reach pest status, and which systems are susceptible to invasion (Heger and Trepl 2003). In order to complete this goal, it is vital to understand long-term dynamics of invasive species populations and their interactions with native communities in their introduced range. Most studies of invasions by non-native species are not extensive enough to determine long-term effects on the native systems (Strayer 2010). The first objective of this study is to determine the long-term abundance and biomass of the New Zealand mud snail, (Potamopyrgus antipodarum), in the Greater Yellowstone Area (GYA). The second objective is to analyze the long-term effects of P. antipodarum on the biomass, abundance, and taxon diversity of native benthic invertebrate assemblages in the GYA. The ten-year span of data available for P. antipodarum and the native macroinvertebrate communities at Lower Polecat Creek in Grand Teton National Park and the Gibbon and Firehole Rivers in Yellowstone National Park provide a unique opportunity to study the macroinvertebrate community succession over time. Data from the proposed macroinvertebrate community survey in the summer of 2011 will be compiled with previous surveys from 2001-2009 to evaluate the long-term changes in the macroinvertebrate community at Polecat Creek and the Gibbon and Firehole Rivers.

Mushroom collecting in the Greater Yellowstone Area was relatively poor during the summer of 1999 due to a cool early season followed by dry weather during the summer. It was perhaps the poorest year of a long term study of Cortinarius, which Meinhard Moser and the late Vera and Kent McKnight began in earnest in the early 1980s; later joined by Joe Ammirati. None-the-less during the season Meinhard Moser was able to paint more than forty-five species for the monograph we are preparing on the Cortinarii of this region. At the end of the season, in late August, some good collections of Cortinarii were made at Sandpoint on Yellowstone Lake, and Lilypad Lake in Yellowstone National Park.

Invasive species are one of the primary threats to native biodiversity worldwide (Mack et al. 2000). Two main goals of invasion biology are to identify the mechanisms that determine which introduced species become invasive, or reach pest status, and which systems are susceptible to invasion (Heger and Trepl 2003). Therefore, it is vital to understand how invasive species sustain positive population growth rates in their introduced range. In this study, I estimated in situ survival of the invasive mud snail, Potamopyrgus antipodarium, in order to assess the population viability and life history patterns of this species in the Greater Yellowstone Area. The mean percent survival of P. antipodarium was 86% during the two-week study period. The field survival data is currently being used to construct a demographic population model of how P. antipodarum populations under different environmental conditions.

ABSTRACTEarly 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. Due to expected range expansion in eastern North America, we focus on the destructive New Zealand Mud Snail Potamopyrgus antipodarum (NZMS) invasion. We collected water samples from eight sites that prior evidence indicated were not yet invaded by the NZMS. After filtering these samples to collect eDNA, we used a species-specific probe with qPCR to identify NZMS eDNA. We found evidence for NZMS invasion at five of the eight sites, with later physical confirmation of mud snails at one of these sites. This study is the first example of successful detection of 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.

New Zealand Mud Snail

Environmental DNA (eDNA) detection of aquatic invasive species is currently at the forefront of aquatic conservation efforts because the methodology provides a cost effective and sensitive means to detect animals at low densities. Developments in eDNA technologies have improved detection probabilities for rare, indicator, and invasive species over the past decade. However, standard lab analysis can take days or weeks before results are available and is prohibitive when rapid management decisions are required for mitigation. Here, we investigated the performance of a real-time quantitative PCR system for on-site eDNA detection of New Zealand mud snails (Potamopyrgus antipodarum). Six sites in western Washington, USA were sampled using the rapid eDNA technique and traditional methods, with five samples per site. On-site eDNA detection of mud snails resulted in a 10% increase in positive sites (16/30 = 53% positive) relative to visual surveys (13/30 = 43% positive). In addition, positive associations were observed between mud snail eDNA concentration (eDNA copies per reaction) and the number of mud snail individuals at each site (R2 = 0.78). We show that the rapid on-site eDNA technology can be effective for detection and quantification of New Zealand mud snails in freshwaters. This on-site eDNA detection approach could possibly be used to initiate management protocols that allow for more rapid responses during the onset of biological invasions.

The chief aim of the present study was to reveal changes in a littoral macroinvertebrate community induced by the invasion of the New Zealand mud snail (Potamopyrgus antipodarum). For that purpose, we compared relevant aspects of the lake littoral macroinvertebrate community in pre- and post-invasion periods and determined the trophic position of P. antipodarum in the lake food web by performing the stable isotope-ratio analysis. The analyses performed showed that P. antipodarum is a primary consumer that may utilise a wide range of primary food sources. Overall, our study showed the following effects of the P. antipodarum invasion on the macroinvertebrate community: a definite increase in the total macroinvertebrate biomass, a significant increase in the local macroinvertebrate family richness and diversity, a shift in the community composition from crustacean- to gastropod-dominated. However, P. antipodarum invasion was not found to affect the biomass of local macroinvertebrates, which remained unchanged.

Evolutionary Consequences

Although many efforts are being made to address ecological impacts of invasive species, very little effort has been made to address the evolutionary impacts of biological invasions (Sakai etal. 2001, Cox 2004). Yet these impacts are likely to be widespread; invasive species have been shown to alter patterns of natural selection or gene flow (Parker et al. 1999), and many of the best examples of rapid evolution involve invasive species interacting with native species (Reznick and Ghalambor 2001, Strauss et al. 2006). Hence, I am addressing both the ecological and the potential evolutionary consequences of the invasive New Zealand mud snail, Potamopyrgus antipodarum on native benthic macroinvertebrates in the Greater Yellowstone Area (GYA).

This study will investigate the effects of wildlife ungulate herbivory, principally of elk and moose, upon riparian and stream habitats within the Greater Yellowstone Ecosystem, which encompasses both the Grand Teton National Park and the Yellowstone National Park. The emphasis of the research will concern how these effects express themselves within the aquatic macroinvertebrate community. Sampling conducted in August and October of 1996 revealed that sites subject to moderate and minimal herbivore use contain greater quantities of allochthonous material and a more diverse macroinvertebrate trophic structure than streams incurring heavy herbivore use.

New Zealand Mud Snail

Accurately predicting the effects of introduced species on native commumtles and ecosystems is a challenge. Utilizing methods of food web ecology, we measured grazing effects of the invasive freshwater New Zealand mud snail, Potamopyrgus antipodarum, in streams within the Greater Yellowstone Ecosystem. Previous results indicate that P. antipodarum can significantly reduce algal standing stocks in less than one week, but it is not yet known if grazing effects vary across streams differing in benthic algae production. In this study, we measured the strength of P. antipodarum grazing on algal resources across six streams varying widely in ambient primary production. In field enclosure experiments within each stream, we estimated direct grazing effects of snails on algae by measuring chlorophyll a, gross primary production and chlorophyll a-specific primary production. In most streams, P. antipodarum decreased overall algal standing stocks, as measured by chlorophyll a, even though gross primary production was not affected. As a result, chlorophyll-a specific primary production increased in productive streams. Finally, standardized comparisons of P. antipodarum-algae interactions indicated that grazing effects were largest in the most productive streams. The overall impact of P. antipodarum on native stream communities will be greatest in the most productive streams if these assemblages are also capable of supporting dense P. antipodarum populations.
