Species that expand their range in response to human-induced environmental perturbations, for instance due to climate or land use change, have been recently termed neonatives. Neonative species differ, biogeographically, from both native species (i.e. species present in a region since historic times) and the so-called alien species. While alien species have been accidentally or voluntarily moved by humans into areas in which they did not historically occur, neonative species have expanded their range via natural dispersal in response to anthropogenic environmental changes. As the phenomenon of species that expand their ranges seems to be increasing and is undisputed, it has still to be determined to which degree neonative species fundamentally differ from alien species. In this workshop, we will bring together internationally leading experts in invasion biology and environmental sciences to discuss cutting-edge advances in the research and management of neonative and alien species and identify their key differences. Among others, the following questions will be addressed.

• Do different taxonomic or functional groups differently establish neonative and alien populations?

• Are neonative species more or less likely than alien species to impact their recipient ecosystems and human societies?

• Can methodologies and approaches historically used to investigate the impacts of alien species also be utilized for neonative species?

• Should neonative and alien species be managed differently?

During the workshop, the experts will initially present state-of-the-art knowledge on this topic, from both conceptual and empiric angles. Experts and students will then discuss in smaller groups various aspects that differentiate neonative from alien species in order to identify gaps of knowledge and guide future research efforts. The workshop is aimed at students with a general interest in population, community, and conservation ecology, as well as at students working on alien species and climate change.
