Figure 2

Spatio-temporal population structure of Caullerya mesnili parasites. Principal component loadings on the PCA-axes are based on the frequency of parasite TCS-types; the first two axes account for 84% of the variation in the data. Parasite DNA was obtained from Daphnia hosts originating from seven lakes; some of the populations were sampled over a period of two to five years, resulting in 16 samples altogether (genotyped after pooling of 20 infected host, per sample; see Table 1). If the same lake was sampled 3–4 times, the samples are connected by a line. Three additional subsamples, for which 10 infected individuals (per population) were genotyped individually (Table 1), are shown in grey.
