Comparison of antifouling properties of native and invasive Sargassum (Fucales, Phaeophyceae) species
The invasiveness of algal species can be facilitated by chemo-ecological traits that allow the establishment of invasive species in a highly competitive environment. Anti-bacterial, anti-quorum sensing, anti-diatom and anti-larval properties of the invasive brown macroalga Sargassum muticum and three native Sargassum species from Oman waters were compared in laboratory and field experiments to ...
متن کاملThe role of chemical antifouling defence in the invasion success of Sargassum muticum: A comparison of native and invasive brown algae
Competition and fouling defence are important traits that may facilitate invasions by non-indigenous species. The 'novel weapons hypothesis' (NWH) predicts that the invasive success of exotic species is closely linked to the possession of chemical defence compounds that the recipient community in the new range is not adapted to. In order to assess whether chemical defence traits contribute to i...
متن کاملMobile epifauna inhabiting the invasive Sargassum muticum and two local seaweeds in northern Spain
The mobile epifauna colonizing the invasive brown alga Sargassum muticum (Yendo) Fensholt was compared with assemblages inhabiting two locally established seaweeds (Fucus vesiculosus L. and Cystoseira nodicaulis (Whit.) Roberts) in a sheltered locality of northern Spain. The epifauna colonizing S. muticum was studied in both the shallow subtidal and intertidal pools at mid shore. The main aims ...
متن کاملWater-Borne Cues of a Non-Indigenous Seaweed Mediate Grazer-Deterrent Responses in Native Seaweeds, but Not Vice Versa
Plants optimise their resistance to herbivores by regulating deterrent responses on demand. Induction of anti-herbivory defences can occur directly in grazed plants or from emission of risk cues to the environment, which modifies interactions of adjacent plants with, for instance, their consumers. This study confirmed the induction of anti-herbivory responses by water-borne risk cues between ad...
متن کاملLong-Term Field Study Reveals Subtle Effects of the Invasive Alga Sargassum muticum upon the Epibiota of Zostera marina
Invasive species can alter coastal ecosystems both directly, e.g. through competition for substratum and nutrients, and indirectly. Indirect effects may be mediated by creation of dissimilar or inimical habitats, changes in predator and/or prey assemblages, alterations in associated biota, and perturbations of water movement and thermal regimes. Previous studies have shown that invasive algae c...
