Figure 1. Discriminant analysis of principal components (DAPC) of the transcriptomics (left, n=6) and proteomics (right n=4, except 22:00 when n=8) datasets. Each large circle represents the centroid of a predefined group (time point). Smaller shapes connected to the larger one show the expression pattern for an individual copepod within the group. Daytime time points are yellow or orange; nighttime are in blue or gray. The percentage of variance explained by the linear discriminant (LD) is noted within each axis label.
