摘要: Global warming opens the door for invasive macrophytes in Swedish lakes and streams The increased travelling transporting by man has caused more species to be moved new areas, e.g. ballast water. These are called introduced or alien species. Some manage reproduce grow rapidly their environment. They then Invasive is a threat against biodiversity an economical problem. compete with other can change environment these In this study aquatic plants (macrophytes) treated. have such immense growth that they obstacle swimmers anglers. Examples of been Sweden problems water weed (Elodea canadensis) fringed lily (Nymhopides peltata). Due emissions so greenhouse gases, scientist believes climate changing. estimate annual mean temperature will rise 2.5–4.5°C. consequences previously was not able survive might future. I compiled list vascular somewhere world. examined if described as could establish Sweden, both at current climate, future predicted two different models from Metrology Hydrology Institute (SMHI). By matching distribution using computer program GARP (Genetic Algorithm Rule-set Prediction), created niche each niches projected onto climate. results show risk introductions freshwater habitats increase Many also which biggest possibility are: Azolla filiculoides, Crassula helmsii, Lagarosiphon major, Lemna minuta, Myriophyllum aquaticum Zizania aquatica. warmer
