Understanding the impacts of alien species on ecosystems is crucial as these species can disrupt local biodiversity, lead to the extinction of native species, and alter ecosystem functions. Invasive alien species often lack natural predators and can rapidly proliferate, causing significant ecological changes and economic losses. They may compete for resources, introduce diseases, and hybridize with native species, complicating conservation efforts. By studying these impacts, we can develop effective management strategies to mitigate harm and preserve native ecosystems, maintaining their biodiversity and resilience.
