Effects of kelp phenolic compounds on the feeding-associated mobility of the herbivore snail Tegula tridentata

摘要: Tegula tridentata, is a common herbivore gastropod inhabiting the subtidal Lessonia trabeculata kelp forest, which tends to show higher densities after harvesting. We investigated if harvested beds may harbor of invertebrates, and underlying mechanisms. Thus, we evaluated exudates L. trabeculata change seawater levels soluble phenols, known have deterrent effect against feeding behavior some invertebrates. Finally whether increase in T. tridentata grounds could be related decrease phenols. Our results showed that density invertebrate herbivores increased up 32% grounds. provide first estimate rate phenolic exudation by L. trabeculata, demonstrate changes its food dependent movement presence with synthetic phloroglucinol. suggest recovery ecosystems can jeopardized herbivory triggered water-borne compounds.
