Abstract: The invasive species is of global importance. It is recognized as one of the leading threats to biodiversity and imposes tremendous costs on agriculture, fisheries, wetlands, forestry, natural areas, and other human enterprises, including human health. The nature and distribution of invasive species has no geographical boundaries. The invasive plants (native, non-native, or alien) tend to have many similar biological attributes/traits relating to high reproduction and stress tolerance. These traits include germination of seeds without complicated requirements, rapid seedling growth, vegetative and sexual reproduction at early stage, aggressive spread by runners or rhizomes, diverse dispersal mechanisms, and the ability to tolerate a wide range of environmental conditions. Invasive species have been identified as the second biggest threat to biological diversity after habitat destruction. Will invasive weeds make ecological adaptation with climate change? What impacts do these plants may have in agriculture, health and the environment?.
