Abstract

There are many knowns and unknowns about invasive species and their patterns. The purpose of this research is to investigate variation in invasion history between invasive trematodes, snails, and waterfowl. To do this, snails (Bithynia tentaculata) were crushed and analyzed under a microscope to find metacercariae (Cyathocotyle bushiensis and Sphaeridiotrema spp.), which are the parasites that infect the host. They were counted and added to data showing prevalence, abundance, and intensity. Data from 2018, 2019, and 2020 were compared to each other to check for annual variation in prevalence, abundance, and intensity between the years. Even though the data for 2020 needs to be completed, variation was seen in all factors over the three years. Future work can be done in order to make a connection between infection dynamics and waterfowl mortality rates.
