Most Optimal Sampling Source for terrestrial biodiversity monitoring (MOSS)

Developments in the field of environmental DNA (eDNA) have revolutionized biodiversity monitoring by providing cost-effective methods to detect organisms across the tree of life. Currently we use variety of eDNA sampling methods, but many are highly laborious and need specific sampling equipment. A solution for this is to use material that naturally collects eDNA from the surroundings that can be sampled to monitor biodiversity. Sponges are excellent for this purpose in marine environments, but we miss a comparable source for terrestrial environments. I propose that globally widespread mosses (Bryophytes) could act as natural eDNA samplers in terrestrial ecosystems. MOSS will investigate this prediction and assess the ability of DNA capture from microbes to vertebrates. Success of MOSS will enhance the current biodiversity monitoring toolset by presenting an easily accessible, cosmopolitan, and readily available terrestrial eDNA source that has been under our noses this entire time.
