• ]. In turn, the termites cultivate and clean the fungus gardens; thus, protecting them from infestation by invasive species (e.g., mycoparasitic Trichoderma species). Despite targeted efforts, strong evidence for defensive microbial symbionts has remained elusive [92]. Only one study showed that the

• oxylipins. Common products are 7,8-dihydroxyeicosatetraenoic acid and a novel eicosanoid with an unusual γ-lactone moiety. Several prostaglandins were predominantly formed by the invasive species. The role of some of these metabolites was investigated by surveying the attachment of E. peruviana on

Keywords: activated chemical defense; invasive species; oxylipins; prostaglandins; red algae; regulation; Introduction The red alga Gracilaria chilensis is native along the Chilean coast and is commercially farmed for the production of agar hydrocolloids [1

• . vermiculophylla cannot explain its success as an invasive species if only grazing by the generalist E. peruviana is concerned. Nevertheless, prostaglandins play important roles in the chemical defense against the generalist herbivorous isopod Idotea baltica [6]. While E. peruviana is a herbivore that co-occurs
