GoKawiilResearchers use spiderwebs—and fake ones—to sample environmental DNA
Scientists including Curtin University's Joshua Newton found that spiderwebs collect exceptionally rich environmental DNA from surrounding wildlife, outperforming other passive sampling methods like vegetation swabs, water, and soil in identifying vertebrate species. Because collecting real webs means destroying spider homes, University of Waikato genomicist Angela McGaughran tested synthetic Halloween webs instead, finding they captured DNA from livestock, birds, and even fungal spores just as effectively.
