Differences between spring and summer were significant in all regions

  1. Significant differences between particular seasons, regions and their interactions were tested with Tukey HSD post hoc tests, and only combinations where p < 0.05 are presented in the table (*although the overall interaction region:season was not significant for the medium size zooplankton (p = 0.09), the Tukey HSD test output did show significant differences for the one-to-one interactions within each particular region season as detailed below).
