Functional traits of indigenous and exotic ground‐dwelling arthropods show contrasting responses to land‐use change in an oceanic island, Terceira, Azores
Abstract Aim Land‐use change typically goes hand in hand with the introduction of exotic species, which mingle with indigenous species to form novel assemblages. Here, we compare the functional structure of indigenous and exotic elements of ground‐dwelling arthropod assemblages across four land‐uses...
