data

all.csv contains the results of cross-inoculation experiments; each line is a specific parasite * host combination. The column "Virulence" is infectivity (0 or 1)

Variables_dynamique.xlsx contains host and parasite population sizes

population_sizes_dynamics contains R code to analyse the dynamics of host and parasite populations

correlations_and_nestedness contains R code to analyse the infectivity matrices (analyses ii to iv in the paper)

temporal_trends_infectivity contains R code to analyse temporal trends in infectivity (analysis v in the paper)
