Fig. 3.

Trophic structure of drought mortality and stress across plant and animal taxa inside (A) and outside (B) areas infested with large populations of the European rabbit, O. cuniculus, showing declining impact at higher trophic levels. The size of a minimum circle surrounding each icon is directly proportional to the number of biotic impact records. Pie charts indicate the proportion of mortality records (black) vs. stress records (white). Examples of major groups for which few or no records exist (absent) are provided in each trophic level; from Top to Bottom: dingo (C. familiaris), raptors, owls, red fox (V. vulpes), feral cat (F. catus), crows and ravens (Corvidae), waterfowl (especially Anatinae), Muridae, gliders, turtles (especially Chelidae), flies, ants, and aquatic and riparian reeds, rushes, and other plants (including Phragmites, Typha). *Introduced species.
