Diet of the exotic Madeiran wall lizard: first insights into trophic interactions in an Atlantic seabird sanctuary

The Madeiran wall lizard Teira dugesii is a relatively new species to the Azores Archipelago, where it was accidentally introduced about 150 200 years ago. This lacertid quickly became naturalised and now occurs in all nine main islands of Azores. At Praia Islet, off Graciosa Island, recently observed preying on chicks threatened Monteiro’s storm-petrel Hydrobates monteiroi . To characterise lizards’ trophic niche, we conducted study diet at using stable isotope analysis next-generation sequencing. Our results indicate that has varied diet, consisting least 23 invertebrate taxa, 17 plant species, occasionally, birds (two detected, including storm-petrels). Marine derived food items were present few samples, vital monitor interactions Islet ensure conservation this storm-petrel.
