- Title
MARINE RESERVES REESTABLISH LOST PREDATORY INTERACTIONS AND CAUSE COMMUNITY CHANGES IN ROCKY REEFS.

- Abstract
The article reports on the restoration of the lost predatory interactions of marine reserves and the community changes in Mediterranean rocky reefs. Protected areas fostered higher density and size of the most efficient fish preying on sea urchins compared with unprotected areas. Predation of medium-sized sea urchins at protected areas were also evident and common as shown by the bimodal structure of Paracentrotus lividus. The size range of consumed sea urchins are directly proportional with the size of Diplodus fish. Thus, size reduction of predatory fish caused by fishing affects the patterns of sea urchin predation and that fishing prohibitions may restore lost interactions on interactive species in rocky reefs with consequential effects.
