  1. This table lists all taxa presented in figures and taxa for which at least on one sampling date a statistically significant effect was observed
  2. ↓ = reduction in abundance, ↑ = increase in abundance, – = no significant effect (Williams test, p > 0.05). SI Supporting Information
  3. * Low density means that the number of individuals per sample was on average <10 individuals/mL when the statistically significant difference was observed
