  3. For each experiment (referred to by their number: #), the D. magna clones (Host clones) and the P. ramosa strains (Parasite strains) used are indicated. The protocol used for the exposure(s) is given, described by the number of spores per Daphnia added (spore nb), the number (nb), the length (time) and the age (age) of the individuals when each exposure was performed. The environmental conditions of the experiment are detailed. For food, the algae species (Sp.: C for Chlorella, S for Scenedesmus) and the quantity (qty, in millions of cells) are indicated. The temperature(s) at which the experiment was performed (T°), the number of replicates per treatment (rep), the number of individuals per jar (ind/jar), the jar size, the controls used [Cont.: crushed unexposed Daphnia (c. D.) or sterile water (H2O)] and the total length of the experiment (Expe time) are also given.
