Non-native species can help ecosystems

When new plants and animals enter an environment, they often damage it, but Dov Sax (2009) points out the many ignored benefits of certain invasive species, such as honeybees in the Americas. In his paper, Sax says non-native species can fill in gaps left by extinct species and could help ecosystems adapt in a future of rapid changes in climate and land use.

A new study validated the environmental DNA (eDNA) method for detecting even small populations of marine animals. The study specifically validated the use of eDNA by David Lodge and his colleagues to find invasive Asian carp in Lake Michigan. Scientists could also use the method for detecting the presence of endangered species thought to have gone extinct.
