However, not all exotic species become invasive. As novel climate conditions develop, novel communities made up of new combinations of species are emerging as populations and species adapt and shift their ranges differentially, not always with negative consequences  . Novel communities differ in composition, structure, function and evolutionary trajectories, as the proportions of specialists and generalists, native, introduced and range-shifting species change and species interactions are altered, ultimately affecting ecosystem dynamics and functioning . The exact nature of novel communities is difficult to predict because species-level uncertainties propagate at the community level due to ecological interactions . However, observations, experimental mesocosms , and theoretical models  provide support that novel communities will continue to emerge with climate change .
