Abstract
Invasive species, or non-native organisms, pose significant threats to global biodiversity, ecosystems, and economies. This review provides a comprehensive analysis of invasive species, their impact on native biodiversity, and the mechanisms driving their success. Invasive species outcompete native species for resources, disrupt ecosystem functions, and alter habitats, potentially leading to the extinction of native species. The review highlights the ecological, economic, and social implications of invasive species, emphasizing the urgent need for effective management strategies. It examines the invasion pathways, factors influencing their establishment and spread, and the competitive dynamics between invasive and native species. Various assessment methods, including ecological surveys, modelling, and genetic analyses, are discussed to understand and mitigate the impacts of invasions. The review also explores international efforts and policies to manage invasive species and suggests future research directions to enhance conservation strategies. By addressing these issues, this review aims to contribute to the preservation of native biodiversity and the maintenance of ecological balance.
