Cipangopaludina Chinensis: Effects of Temperatures and Parasite Prevalence
Cipangopaludina chinensis: Effects of temperatures and parasite prevalence BIOS 35502-01: Practicum in Environmental Field Biology Jennifer Lam Advisor: Sara Benevente 2016 Lam 2 Abstract Comparison of parasite prevalence between native snail species, Lymnaea stagnalis, and invasive snail species, Cipangopaludina chinensis, was conducted by euthanizing snails one day after capture from Brown Lake. Looking at if parasitism is a main factor in intraspecific competition of C. chinensis at different temperatures, snails were captured, measured for height and width, housed under different temperature settings (20◦C, 25◦C, and 34◦C), and competed against other for a week-long trial. After the week-long trial or when the last snail died, snails were re-measured for growth and checked for parasites. Result from parasite prevalence between two snails species was significant, C. chinensis rarely had infections compared to L. stagnalis. From the result, native parasites were predicted to be highly specialized for L. stagnalis and lack mechanisms to penetrate C. chinensis. Result from the intraspecific competition suggested that parasite prevalence was not important as survival (in weeks) in the change in growth. Since parasite prevalence was low, and sample size was small, conclusion on parasite prevalence not being a factor in growth was not robust. Further studies on impact of C. chinensis on freshwater systems and native snail species are needed. Introduction Climate change is a concerning factor for freshwater ecosystems. Climate change increases the average temperature of water in some aquatic systems. With warmer water temperatures, more exotic species can establish as native species disappear (Rahel and Olden 2008). As native species disappear from the ecosystem, other species dependent on a specific native species may not be able to sustain the loss, leading to a decrease in biodiversity. -
Emergence of Laricobius Nigrinus (Fender) (Coleoptera: Derodontidae) in the North Georgia Mountains1
Emergence of Laricobius nigrinus (Fender) (Coleoptera: Derodontidae) in the North Georgia Mountains1 C.E. Jones2, J.L. Hanula3, and S. K. Braman4 Dept. of Entomology, University of Georgia, 41 3 Biological Sciences Building, Athens, Georgia 30602, USA J. Entomol. Sci. 49(4): 401-412 (October 2014} Abstract Hemlock woolly adelgid, Adelges tsugae An nand, is currently found throughout most of the range of eastern hemlock, Tsuga canadensis (L. ) Carriere. Biological control agents have been released in attempts to control this pest, but how different climates influence the efficacy and survival of these agents has not been studied. One predatory beetle of A. tsugae, Laricobius nigrinus Fender, is native to the Pacific Northwest and, therefore, experiences a much different summer climate in the north Georgia mountains. To better understand survival of this predator as it aestivates in the soil, 5 mesh cages were set up at each of 16 sites with 4 sites located at an elevation below 549 m, 4 sites between 549 m - 732 m, 5 sites between 732 m - 914 m, and 3 sites over 914 m. At each site 30 larvae were placed inside one of the cages during March, April, or May on a bouquet of adelgid infested hemlock twigs, and emergence of adults was monitored in the fall . Of the 1440 larvae placed at the 16 sites, only 4 adult beetles emerged between 06 October 2012 and 05 November 2012. The overall success rate remains unknown, and more research is needed to assess the efficacy of L. nigrinus as a biological control agent in Georgia. -

Adelges Tsugae), a Relative of the Aphid, Is a Destructive Invasive Species in the Catskills
Background: The hemlock woolly adelgid (Adelges tsugae), a relative of the aphid, is a destructive invasive species in the Catskills. Detected in the southeast in the 1960s, this native of Asia has been present in the Hudson Valley and Catskills for the last 25 years. The adelgid consumes the tree’s sap and causes Hemlock trees to drop new shoots. In most cases, infestation results in tree mortality within 10 years. The wind and birds are the insect’s primary vectors: often HWA spreads along waterways Hemlock wooly adelgid under magnification (left) and infesting a hemlock tree where birds tend to perch for prolonged periods of time. Biological Control: Classical biological control Current work: CRISP recently released 500 Laricobius beetles. These predators attempts to keep populations of invasive species in check by utilizing predators hailing the same region were released at Mine Kill State Park in as their target prey or host. Biocontrol agents do late November 2013. Mine Kill State Park not eradicate the invasive species they feed on, but was selected for release as the stands of keep population levels very low, and under control. hemlock there are still healthy, and in the There is now hope that Hemlock Wooly Adelgid very early stages of infestation, so the can be sustainably managed using biological predators will have plenty of adelgids to control. The tiny Laricobius beetle is native to the eat. With this initial collection of 500 Pacific Northwest region of the United States and bugs, CRISP released about 150-200 per Actual size of Laricobius has recently been recognized as the most effective tree and will continue to monitor them predator of HWA. -

POTENTIAL THREATS OF THE EXOTIC APPLE SNAIL POMACEA INSULARUM TO AQUATIC ECOSYSTEMS IN GEORGIA AND FLORIDA by SHELLEY MARIE ROBERTSON (Under the Direction of Susan Bennett Wilde) ABSTRACT The Island apple snail, Pomacea insularum is a freshwater gastropod in the family Ampullaridae. It was introduced into the United States via the aquarium trade approximately 30 years ago and now has established reproducing populations in at least seven southeastern states. It is a highly invasive species with high rates of reproduction and consumption of native aquatic vegetation. A survey of reported Georgia populations confirmed that there are at least ten individual occurrences of exotic apple snails in the state, and that they have not reached their equilibrium distribution. We also investigated the ability of P. insularum to harbor a cyanotoxin that may be detrimental to its avian predator in Florida, the endangered Florida snail kite (Rostrhamus sociabilis). The invasive P. insularum transferred the undescribed cyanotoxin associated with Avian Vacuolar Myelinopathy to domestic chickens in a laboratory feeding study.

Presence on Native Snail and Bivalve Populations
Ellman 1 Impacts of Chinese mystery snail (Cipangopaludina chinensis) presence on native snail and bivalve populations BIOS 35502-01: Practicum in Field Biology Michael Ellman Mentor: Shannon Jones 2019 Ellman 2 Abstract The Chinese mystery snail (Cipangopaludina chinensis, or CMS), a species native to East Asia, has become widely established in the United States and may be negatively impacting native snail populations, while its effects on native freshwater bivalves are unknown. My study examined the influence of CMS on survivorship of native snails and bivalves with exclusion cages on two creeks in the Upper Peninsula of Michigan. There were no significant differences in native snail or bivalve populations between cages with snail populations left intact and populations with CMS removed, indicating either a flaw in experimental design or that CMS have no effect on these animals. In addition, there was no significant difference in native snail and CMS populations between different mesh sizes used to attempt to exclusively restrict movement of CMS. However, bivalve populations were found to be significantly higher in Tenderfoot Creek than in Brown Creek, perhaps due to the open vegetation and substrate composition in the part of Tenderfoot Creek tested. Native snail and bivalve populations were found to be higher in exclusion cages than in similar unfenced areas, possibly due to lower water flow rate in the cages. As the effect of CMS on native snails and bivalves could not be determined, conservation efforts should not be altered from current practices for now. Further studies could focus on mesocosm experiments involving CMS impact on native snail and bivalve communities and examine bivalve populations across habitat types. -

U.S. Fish and Wildlife Service Southeast Region Inventory and Monitoring Branch FY2015 NRPC Final Report Documenting freshwater snail and trematode parasite diversity in the Wheeler Refuge Complex: baseline inventories and implications for animal health. Lori Tolley-Jordan Prepared by: Lori Tolley-Jordan Project ID: Grant Agreement Award# F15AP00921 1 Report Date: April, 2017 U.S. Fish and Wildlife Service Southeast Region Inventory and Monitoring Branch FY2015 NRPC Final Report Title: Documenting freshwater snail and trematode parasite diversity in the Wheeler Refuge Complex: baseline inventories and implications for animal health. Principal Investigator: Lori Tolley-Jordan, Jacksonville State University, Jacksonville, AL. ______________________________________________________________________________ ABSTRACT The Wheeler National Wildlife Refuge (NWR) Complex includes: Wheeler, Sauta Cave, Fern Cave, Mountain Longleaf, Cahaba, and Watercress Darter Refuges that provide freshwater habitat for many rare, endangered, endemic, or migratory species of animals. To date, no systematic, baseline surveys of freshwater snails have been conducted in these refuges. Documenting the diversity of freshwater snails in this complex is important as many snails are the primary intermediate hosts of flatworm parasites (Trematoda: Digenea), whose infection in subsequent aquatic and terrestrial vertebrates may lead to their impaired health. In Fall 2015 and Summer 2016, snails were collected from a variety of aquatic habitats at all Refuges, except at Mountain Longleaf and Cahaba Refuges. All collected snails were transported live to the lab where they were identified to species and dissected to determine parasite presence. Trematode parasites infecting snails in the refuges were identified to the lowest taxonomic level by sequencing the DNA barcoding gene, 18s rDNA. Gene sequences from Refuge parasites were matched with published sequences of identified trematodes accessioned in the NCBI GenBank database.
