Spatial and temporal pattern of a pollinator-transmitted pathogen in a long-lived perennial, Silene acaulis

Questions: Does the spatial structure or rate of spread of anther-smut disease differ among plots with low versus high density of the host Silene acaulis or low (<6%) versus high (25%) disease frequency? What is the demographic pattern of seedling recruitment and host mortality in S. acaulis? How do the temporal dynamics of anther-smut disease differ among hosts that vary in lifespan and population persistence? Organisms: Silene acaulis, a long-lived alpine tundra perennial, and Microbotryum violaceum, a pollinator-transmitted fungus that causes anther-smut disease
