1. The introduction of a non-native species frequently has adverse direct effects on native species. The underlying mechanisms, however, often remain unclear, in particular where native and invasive species are taxonomically similar. 2. We found evidence of direct competitive interactions between a globally distributed invasive species (the Pacific oyster, Magallana gigas) and its native counterpart (the European oyster, Ostrea edulis). We also discovered that the competitive outcome differed between different habitat types and structures by identifying context-dependent responses driven by environmental conditions and stress (i.e. intertidal compared to subtidal habitats; and vertical versus horizontal substratum). This is particularly important because the European oyster is threatened, or in decline, throughout most of its range and restoration efforts are underway in many regions. 3. We combined experimental manipulations and stable isotope analysis (SIA) to identify the direct effects of competition and ... : Zwerschke_et_al_2018_IBIS_BiomassBiomass.csvZwerschke_et_al_2018_IBIS_GrowthRate_MortalityGrowthRate_Mortality.csvZwerschke_et_al_2018_IBIS_SIA_OysterSIA_Oyster.csvZwerschke_et_al_2018_IBIS_SIA_ResourceSIA_Resource.csv ...
