Studying non-native species in ecology is significant as these species can disrupt local ecosystems through competition, predation, or disease transmission. Understanding their impacts helps us formulate strategies to manage their spread and mitigate negative consequences on native biodiversity. Non-native species often outcompete native ones for resources, which can lead to local extinctions and altered food webs. By researching non-native species, ecologists can also enhance conservation efforts, restoring balance and functionality to ecosystems and protecting native flora and fauna.
