This is a slightly older paper, note that air environmental DNA now has progressed a lot, especially for species mapping. Here's a cool recent paper showing you can extract DNA of local species from spider webs, by sequencing DNA stuck to spider webs from next to a zoo https://www.sciencedirect.com/science/article/pii/S2589004224001251 https://www.sciencedirect.com/science/article/pii/S258900422...
