Invasive species are non-native organisms that are introduced to a new environment and have negative impacts on native species, ecosystems, and human activities. These invasive species can outcompete native species for resources, disrupt food chains, spread diseases, and alter habitats. They can have significant economic, environmental, and social consequences, and are a major concern for conservation efforts worldwide. Research in invasive species focuses on understanding their biology, ecology, and impacts, as well as developing strategies for prevention, management, and control.
