Understanding interactions among different species plays an important role for the understanding of key ecological processes. In Galapagos, invasive species presence increased significantly before the establishment of regulations by the local authority. Unlucky, many of these species are now distributed in different islands in this archipelago and is imperative to understand the impact they are causing to other species (native and introduced as well). This is why, in collaboration with PhD Selene Escobar we are investigating how invasive ant species and their distribution and density, are affected by vegetation type in different sites along the whole archipelago. We are mainly focusing on the interactions non-native ants may present with other non-native/ invasive species, native biota and landscape aspects in our long-term monitoring sites.
