EXPERIMENTAL EVIDENCE FOR THE DISRUPTION OF PREDATOR - PREY INTERACTIONS BY CHEMICAL POLLUTION

Predator - prey relationships are complex and chemical communication plays an important role. The role of chemical communication between Scorpaena porcus and Pomatoschistus spp. was assessed including the added effects of a herbicide. Tank trials featured living free - roaming and confined S. porcus as well as a maquets. This allowed for manipulations of cues perceived by the prey. Trials were performed in chemically polluted and unpolluted seawater. Pomatoschistus spp. assessed predation threats using multiple sources of information. Kairomones of S. porcus were detected by the prey, yet simultaneous visual and olfactory cues resulted in stronger anti - predator responses. Glyphosate disrupted predator - prey interactions.This work was supported by the Croatian Science Foundation under the project COREBIO (3107).
