scientists say this collect DNA can be used for identifying what plants and animals have been in the areas, it also helps documents change in the environment over time,
researchers say the finding suggest air quality measurement devices have collect large amount of biodiversity data.
an animals and plants go through their life cycle and their leave small pieces of themselves environment, this includes materials such as fur, feathers and pollen that identify their genetic makeup, but has been much harder to get a genetic picture of animals living on land. said Kristine Bohman.
In2021, both Bohman and Clare worked on similar project to see whether they could pull animal DNA from air. after sitting up collection in local zoo, the team were well able to capture and examine DNA from many different species.
after getting DNA from pieces inside the air filter the team was able identify more than 180 different kinds of animals and plants, this is scientists to discover resolute.
Allerton noted many countries have network to measure air quality. some also store their old filter many years. he said such data could help demonstrate how ecosystems have changed over time.
this is the DNA projects for scientists discover resolute issue
