This review provides a comprehensive analysis of invasive species, their impact on native biodiversity, and the mechanisms behind their success. Invasive species compete with native species for resources, disrupt ecosystem function, and alter habitats, potentially leading to the extinction of native species. This review highlights the ecological, economic, and social impacts of invasive species and emphasizes the urgent need for effective management strategies. It examines invasion pathways, factors influencing their emergence and spread, and the competitive dynamics between invasive and native species. Various assessment methods, including ecological surveys, modeling, and genetic analysis, are discussed to understand and mitigate the impacts of invasions. This review also examines international efforts and policies to manage invasive species and suggests future research directions to improve conservation strategies. By addressing these issues, this review aims to contribute to the protection of native biodiversity and the maintenance of ecological balance. Copyright@ International Science Community Association
