Detected species interactions across data segments for the various time series transformations methods using Granger causality.

Interaction was judged to be detected if the p-values calculated were significant for at least three model orders (for q = 1 to 10) of the Granger causality tests. A → B means A Granger causes B, A ↔ B means symmetric interaction,—means less than three model order were significant hence no interaction detected.
