\section{Initial Findings}  \subsection{Alpha Diversity}  Fig. 1 - Overall, there is a lot of methylotenera and planctomyces. Vallisneria leaves at P1 had large proportion of Providencia. Unknown host species leaf at P1 had Acinetobacter. Site P2 roots, especially Redhead Grass had sulficurvum and sulfurimonas. The grey portion on the Vallisneria roots at P2 and P3, as well as the grey in Eurasian watermilfoil roots at P3 are mostly made up of the family Rhodocyclaceae, but there was not enough resolution down to genus to see this. The grey portion of Vallisneria roots at P3 is also in large part made up of the family auto67\_4W. ***should go find some literature on what these genera and families do***  \subsection{Beta Diversity}  Fig. 2- Fig. 2  shows a PCoA using unweighted UniFrac. A shows the whole dataset. Leaves and roots tend to cluster separately within each site. In addition, the sites cluster into two groups: P1, P3, P4 make up one group and P2 makes up another group. Panel  B shows data for only site P2 in order to examine patterns between samples within only one site. Site P2 was chosen since it was the most distinct in microbial community compared to P1, P3, and P4.  It is apparent that samples are differentiated by whether they are leaves or roots and by the host species. Leaves and roots are most differentiated in Redhead Grass and Vallisneria. At the same time, the leaves (regardless of host) tend to cluster more tightly with each other than the roots with themselves. Still, there are distinct clusters differentiated by the host species within site P2.
