What is an invasive species: an alien species whose introduction does, or is likely to cause economic or environmental harm, or harm to human health. Traits: wells dispersed, exploit disturbance, germinate fast, and shorter life cycle. Higher npp, higher leaf nutrients, grow faster, shorter life cycles can produce many more growing seasons". Invasives produce more seeds so they are easily dispersed. Not very useful because r-selected species share these traits and lack of information in the public about invasive species. Native species are r & k selected while invasive species are r selected; the two are similar in ways but invasive species cause harm to the environment. Invasives have more phenotypic plasticity to acclimate better to new environments.
