LETTER Contemporary evolution of an invasive grass in response to elevated atmospheric CO2 at a Mojave Desert FACE site Judah D. Grossman1 and Kevin J. Rice2* Abstract Elevated atmospheric CO 2 has been shown to rapidly alter plant physiology and ecosystem pro- ductivity, but contemporary evolutionary responses to increased CO An invasive species is a species that causes harm to its non-native environment. Once Knapweed begins to grow in an area it will form a very dense patch that will push out all of the native vegetation. It is in the Southwestern United States, primarily within southeastern California and southern Nevada, and it occupies 47,877 sq mi (124,000 km 2).Small areas also extend into Utah and Arizona.
