Pop describes the effect of replicate selection lines within the treatments (predator absent or predator present) on the trait means, i.e. the divergence of populations with identical selective environment.

The direction (where applicable) means the direction of mean change of the ‘predator present’ treatment compared to the ‘predator absent’ treatment, or the direction of mean change of the red clones compared to the white clones. Null (0) denotes no difference between these treatments.
