Science: Invasive species can be found through airborne DNA from plants

Now, researchers have proven that simply capturing and analyzing the DNA released by plants into the air can be as effective as putting a boot on the ground, and in some cases even better

Researchers say this method helps track how climate change changes the composition of plant communities and provides early warning of invasive species

BMC ecology and evolutionThis work brings environmental DNA (eDNA) research into a new field, namely the release, defecation, coughing, or other ways of releasing genetic material into the environment

The unique shape of these particles allows us to identify invisible species simply by capturing their pollen

Johnson said: "We can find no flowers, no pollination of species, or they are not active in the winter time

In his university, he studied in a small sandpit with his colleagues on a small prairie

Both surveys found the same 13 species of grasses, but eDNA's work found another 13 species

Lorenrieseberg, a plant evolutionary biologist at the University of British Columbia in Vancouver, says this is encouraging

"This report may encourage more researchers to adopt dust-proof devices to supplement" other types of surveys, especially in long-term research sites, said Fabian Roger, an ecologist at ETH zu rich , He was not involved in this work

"The underlying air DNA is incredibly diverse and represents all of the biodiversity," Roger said

A more effective filter, or a trap equipped with a fan to suck in air, can work better

"I can't see the app," he said

Roger said: "The air may become the'water' above the land
