Abundance patterns of selected genera and theorized trophic links. Abundance profiles (a) of some genera with trophic interactions described in the literature suggest potential top-down regulation models (b) in our dataset. (a) Raw abundances of several selected genera along the time series. Stars denote differentially abundant counts between the control and the amended treatment at a given time point (b) Models of potential trophic interactions between the selected genera.
