Distributions of non-native species are currently limited by water temperature. Non-native marine organisms (e.g. japweed and Chinese mitten crab) are spreading and becoming established in our waters through a combination of climate change, migration and human introductionThe action bringing a non-native species to a new environment, as opposed to an extension of range.. These can cause major ecological changes.
