Spider Webs Capture DNA From The Surrounding Environment, Which Can Be Used To Learn More About Wildlife

At Perth Zoo, DNA from 61 species was found, while DNA from 32 species was identified at the Karakamia sanctuary.

The difference is likely due to the greater density of animals at the zoo. The different types of spiderwebs that were gathered may also affect the type and amount of DNA collected.

Scientists aren’t sure how far eDNA travels or how long it lasts. It allows them to determine what kinds of animals are around but not how many there are.

So, while collecting spiderwebs for DNA is a clever innovation, it can be limiting when it comes to measuring biodiversity. Still, the technique is a game-changer and can be used in conjunction with other tools.
