The use of multi-biomarkers to assess the potential trophic competition between marine native and non-indigenous species

The potential trophic niche overlap between native and non-indigenous species of a coastal lagoon in Portugal will be studied with the use of multi trophic biomarkers (fatty acids and stable isotopes). This project will focus on two pelagic species (the native blue mussel – Mytilus edulis, and the non-indigenous pleated sea squirt – Styela plicata) and two benthic species (the native common cockle – Cerastoderma spp. and the non-indigenous manila clam – Ruditapes philippinarum). The samples were collected throughout one year at the Albufeira coastal lagoon (Portugal) and were analyzed at the Institut des Sciences de la Mer de Rimouski-UQAR (Canada). This internship will allow the integration of the acquired data and the analysis and interpretation of the results with the goal of publishing the main findings in a scientific peer-reviewed journal.
