    Counting the plants in a forest or field, or looking for invasive species, takes days of hard work, trekking through thorny bushes and grass full of lice


    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


    Monitoring life on earth.
    Roger said: "The air may become the'water' above the land
