Graphical summary of the response of diversity indices, macroinvertebrate feeding functional groups and ecological groups during a fish eradication campaign in adjacent lentic and lotic (R1: inflowing river; R2: outflowing river) ecosystems. Up and down arrows, respectively, indicate increasing and decreasing trends associated with different probability levels (i.e., p levels from linear regression models and generalized linear models). MICRO.: microhabitats; San: mud/sand; Bou: boulders; Gra: gravel; Peb: pebbles; Mos: aquatic mosses.
