Figure 3.
Principal Component Analysis (PCA) plot of gene expression patterns in all Calanus spp. samples. The numbers in the symbols indicate the sampling day, i.e. 0, 5, 13 or 20. The borders surrounding the symbols indicate species, i.e. C. finmarchicus (C.fin), C. glacialis (C.gla) or a mix of the two species. C5s in the reference (Ref) group (red, in early diapause) clustered to the far right, and experimental (Exp) adults (green) to the far left. The experimental C5s (blue) were positioned somewhat variably between the reference group and adults, which may suggest some asynchronization in development and diapause phase.
