An Alien Invader Spawns A Species

The global mixing of plants and animals now going on could be a major channel for unplanned environmental change.

"The ecological alterations that an aggressive alien may bring vary. It can co-opt soil microbes to enhance its growth. It can deny native animals their natural food and shelter. It can create a new wildfire hazard as alien grasses are doing in some North American deserts. New research shows it can even help a new insect species to emerge."{
