Bacterial community structure and membership
Using the Bray-Curtis Dissimilarity distances, parasitise treatment, urbanization, and the interaction between the two variables did not significantly affect bacterial community structure (Figure S2A, parasite treatment: F = 1.52, P = 1.00, urbanization: F = 2.05, P = 1.00, Interaction: F = 1.24, P = 0.48). Using the unweighted UniFrac distances, parasitism, urbanization, and the interaction between the two variables did not significantly affect bacterial community membership (Figure S2B, parasite treatment: F= 1.45, P = 1.00, urbanization: F = 2.26, P = 0.52, Interaction: F = 1.77, P = 0.52). Using the weighted UniFrac distances, parasite treatment, urbanization, and the interaction between the two variables did not significantly affect bacterial community structure (Figure S2C, parasite treatment: F = 2.09,P = 1.00, urbanization: F = 2.73, P = 1.00, interaction: F = 3.14, P = 0.50). Year did not affect Bray-Curtis Dissimilarity, weighted UniFrac, or unweighted UniFrac (Table S2).
