a trend toward significanceP =0.0576
The angular distribution of diurnal acrophases for H3K9Ac peaks proximate to such sites differed from those for peaks distant from such sites ( W =4,572.6, P =0.0136, n =664 samples), and the difference in angular distribution of seasonal acrophases showed a trend toward significance ( W =3,643.2, P =0.0576, n =664 samples).
