abstract
Invasive species are being documented on a global scale. As a result, numerous studies have been conducted to asses the damage caused by them, and to help determine possible changes. The purpose of this research is to continue work determining the difference in nutrient needs between a native and two invasive aquatic snails by measuring ingestion, egestion (fecal matter) and assimilation efficiency of the common nutrient requirements, Carbon (C) and Phosphorus (P). Most of my project has focused on developing the methods that will be applied to the upcoming feeding trials, including establishing digestive turn-over and metabolic rate. Pending the return of samples from the University of Wyoming Stable Isotope Facility, the base line for the ratios of C, N (Nitrogen) and P of adult individuals will also be discussed. This will be the first study to measure assimilation efficiency in the context of C:N:P stoichiometry of an invasive invertebrate species, and the values that I gather will contribute to a growing database of information about invasive species and aquatic ecosystems. Increasing this knowledge base will provide a better understanding of how aquatic ecosystems function and how invasive species affect them.
