The term used to describe a species performing better in its new location than in its native environment is invasive species or invasiveness. Invasive species can outcompete native organisms for resources, disrupt local ecosystems, and alter habitats. Their success often results from the absence of natural predators, diseases, and competitors in the new environment, allowing them to thrive unexpectedly. Understanding the mechanisms behind invasiveness is essential for biodiversity conservation and ecosystem management, as it helps mitigate potential ecological damage caused by such species.
